penicillium digitatum inhalation

(2000) found that the antagonistic yeast-like fungus, Aureobasidium pullulans multiplied rapidly in apple wounds, and reduced decay incidence in apples inoculated with Botrytis cinerea and P. expansum. Gas chromatogram of volatile organic compounds in the atmosphere surrounding wounded oranges. Google Scholar. This stimulation was attributed to the permeation of anthranilic acid from the inner tissues to the fruit surface. This fungus was confirmed to be P. digitatum by molecular identification. Pathogens which penetrate through the host lenticels can feed on the nutrients secreted from the cells adjoining the lenticels, especially after injury following tissue senescence (Eckert, 1978). The development of the CO-sensitive Monilinia fructicola in peaches was completely inhibited in cold storage by the addition of CO to a low-O2 atmosphere (4%); however, a normal rate of rot development was resumed once the fruits were transferred to air at 20°C (Kader et al., 1982). 1949, 26 (4): 507-515. People are commonly exposed to the spores of this airborne pathogen every day. Copyright © 2020 Elsevier B.V. or its licensors or contributors. 2. Escherichia coli . However, none of these patients had antigen-specific precipitating antibodies to P. digitatum in tests of antigen extracted from patient’ sputum culture fluid or sputum. was tested. However, another promoting factor was isolated from the oil and was identified as prangolarin by spectrometric analysis. However, they also found that the antagonist was capable of inducing the activities of β-1,3-glucanase, chitinase and peroxidase in the treated wounds on the fruits. Here, we report a case of fatal pneumonia due to P. digitatum infection, as confirmed by repeated examination of cultured sputum. We confirmed the presence of antigen-specific precipitating antibodies to P. digitatum by using antigen derived from the patient’s sputum culture fluid or extracted from the fungus in his sputum (b). The effectiveness of this fungistatic gas is pathogen dependent and is greatly enhanced in combination with a low-O2 atmosphere (2.3%). Although human infection with P. digitatum is considered rare, it appears that this organism can be very virulent and resistant to antimycotics. The cavity continued to enlarge further. Hawksworth (1981a) gives a long list of additional mycoparasites growing on conidial fungi. PubMed Google Scholar. The species that most commonly cause postharvest spoilage of citrus fruit are Penicillium digitatum (green rot) and Penicillium italicum (blue rot). [1] … Limonene peak shown was attenuated 16 times. and other filamentous fungi: report from SENTRY antimicrobial surveillance program, 2000. 2002, 46: 1032-1037. We found antigen-specific precipitating antibodies to A. flavus and P. digitatum in the patient’s serum (Figure 3a) at April 2005.and pleural effusion at November 2005 by using Ouchterlony double immunodiffusion testing [4] with A. flavus and P. digitatum antigens (HollisterStier, Spokane, WA, USA). 1996, 110: 166-173. A number of condial Ascomycota are hosts to biotrophic parasites. He had therefore had no obvious opportunity for exposure to the citrus pathogen in his work environment or in and around his house. Management of crop health is in fact essential to agriculture. 1x is the concentration typical of the natural mixture measured surrounding wounded oranges. Generally, spores of Penicillium digitatum do not germinate in water on the surface of citrus fruit until the peel is injured (Smoot and Melvin, 1961). These studies indicated that lemon epicarp oil, with the limonene removed, promoted the production of green mold symptoms on only 28% of the wounds, suggesting that limonene was one facilitator of green mold formation on wounded fruits. J Clin Microbiol. Emphasis on microbiological spectra, patient outcome and prognostic factors. Phytopathology. These factors might have facilitated the infection. © 2020 BioMed Central Ltd unless otherwise stated. We diagnosed invasive pulmonary penicilliosis due to P. digitatum. His asthma was of the non-atopic type and moderate, as defined by the Global Initiative for Asthma Guidelines 2002. Penicillium species are among the most common fungi in the environment and are usually considered non-pathogenic to humans [1]. 1999, 89: 716-721. Mascotte, FL 34753 Additional index words. Fungal rots are one of the main causes of large economic losses and deterioration in the quality and nutrient composition of fruits during the postharvest stage. It has been suggested that fruit resistance to infection could be modulated, not only by delaying the normal decline of the antifungal diene by retarding fruit ripening, but also by increasing its synthesis. Penicillium digitatum is widely distributed in soils throughout the world. Since little or no germination of P. digitatum occurred on water agar alone, it was assumed that substrate nutrition was the determinant of spore germination and an important factor in host specificity of the pathogen to citrus fruits. Cookies policy. The authors declare that they have no competing interests. 1978). Penicillium funiculosum can smother various fungi in culture and thus prevent pineapple fruit diseases (Lim and Rohrbach 1980). PENICILLIUM DIGITATUM AND GEOTRICHUM CANDIDUM TO ULTRAVIOLET (UV-C) EXPOSURE Y. J ANETH F ERNANDEZ AND D AVID J. H ALL 1 Fresh Mark Corporation 662 E. Meyers Blvd. At higher concentrations, however, some volatiles, such as acetaldehyde, were found to be fungitoxic (Prasad, 1975) and have been evaluated as fumigants to control postharvest diseases of various crops (see the chapter on Chemical Control- Natural Chemical Compounds). Abstract The association of cereals with fungi cannot be disregarded as their manifestation in our foods poses serious health risks. RIVKA BARKAI-GOLAN, in Postharvest Diseases of Fruits and Vegetables, 2001. The discomycete Bisporella pallescens (synonym Calycella monilifera) fruits densely on the conspicuous black conidial patches of Bispora antennata on tree stumps (Jahn 1968). To extract the antigen from the sputum culture, we added 1.5 mL of Glass Beads (Biospec Product, OK, USA) to the patient’s sputum and crushed the mixture with a Mini-Beadbeater (Biospec Product, OK, USA). 1 displays the stimulating effect of various concentrations of oil produced from an orange rind on the germination rate of P. digitatum conidia. Thus, the presence of citrus juice with the appropriate acidity level can determine both the germination rate and the germ tube growth and, in turn, the rate of fungal development and the incubation period of the disease (Pelser and Eckert, 1977) (Fig. This may be explained by the fact that each potential biocontrol strain evolved to compete in the habitat from which it is obtained and is not as well adapted to other environments.8 Enhancing the effectiveness of biocontrol in diverse natural niches is therefore essential to including it in standard agricultural practices.8, The majority of microorganisms outside fungi that have been investigated as potential biological agents are Gram-negative bacteria including Agrobacterium, Pseudomonadaceae, and Erwinia; finally, several Bacillus strains and actinomycetes have been described to exert this natural antimicrobial activity, but in general Gram-positive organisms have received far less intensive study than Gram-negative bacteria.6 Bacillus species, however (like actinomycetes), show several characteristics that make them interesting candidates as biocontrol agents; mostly, they are abundant in soil and produce various biologically active metabolites, including zwittermicin A.6. Ann Hematol. Our patient had pulmonary emphysema and was elderly, and undernourished. It is also found in paint and compost piles. Diffuse reflectance occurs from waxy, round surfaces, but the ablation effects remove the debris (soil dust and pesticide residues). Bars indicate standard errors. CO examined the patient and contributed to manuscript preparation. A copy of the written consent is available for review by the Editor-in-Chief of this journal form. The fact that the average quantity of volatile compounds emanating from wounded fruits was 75 times greater than that from non-injured fruit may explain the lower germination of P. digitatum spores on water agar exposed to sound citrus fruits. 2001, 120: 177-10.1378/chest.120.1.177. Fig. Article  Certain compounds in the host tissues might, on certain occasions, affect the host susceptibility to infection by stimulating pathogen growth. (2014) observed that addition of purified triterpenoids and steroids from the crude fractions (hexane and chloroform) of G. lucidum exhibited antimicrobial activity against the yeast, C. albicans; Gram-positive (S. aureus, B. subtilis) and Gram-negative (P. aeruginosa, E. coli) bacteria (Vazirian et al., 2014). How each person reacts to the inhalation of Penicillium mold spores is unique. 1990, 83: 701-704. WALTER GAMS, ... KADRI PÕLDMAA, in Biodiversity of Fungi, 2004. Penicillium is among the five most common genera in the outdoor and indoor fungi aerosols {2649, 2747, 2759}. This induction was exhibited in a transient increase in the enzymatic activity which started 24 h after the application of the antagonist, and reached a maximum 48 or 96 h after the treatment. The genus penicillin molecule is a well-known antibiotics drug used in medicine to fight infection from certain kinds of bacteria. (5) It may cause hypersensitivity pneumonitis, allergic alveolitis in susceptible individuals. (1995) investigated the possibility that some components of the lemon peel oil might be essential for fungal development in the peel tissues. This includes soil particles and pesticide residues. Penicillium rot of pineapple was reduced considerably by spraying the fruit with nonpathogenic strains of the pathogen. Penicillin digitatum assists in the creation of immunologically inspired mycological discovery assays needed in the food sector. Antibiotics are in fact synthesized by multienzymatic synthetase complexes, are usually effective at higher concentrations (in the micromolar range), and affect a broad spectrum of microorganisms. The efficacy of thin-film diamond coated electrodes (DiaCell 101) for disinfection of water artificially contaminated with Penicillium digitatum and Pseudomonas spp. This fungus was confirmed to be P. digitatum by molecular identification. We diagnosed the patient with lung aspergilloma and treated with itraconazole (100 mg/day) for 3 months. Holmes LG, Eckert JW: Sensitivity of Penicillium digitatum and P. italicum to postharvest citrus fungicides in California. Effect of concentration of the synthetic mixture of volatile compounds on the germination of Penicillium digitatum spores. The ability of various antagonistic microorganisms to act as alternatives to systemic fungicides and control postharvest diseases may be connected with their ability to produce and secrete antibiotic substances, or their ability to injure the pathogen directly. Anamorphic Ascomycota also host necrotrophic parasites. For example, yeast treatments reduced postharvest rotting of peach and apple. Hansfordia (Dicyma) pulvinata is a destructive parasite on many dematiaceous conidial fungi (Hepperly 1986), particularly Cercospora (Hawksworth 1981b), but also Passalora (Mycovellosiella, Cladosporium, Fulvia) fulva on tomato (Peresse and Le Picard 1980; Le Picard and Trique 1987), and P. (Cercosporidium, Phaeoisariopsis) personata on peanut leaves (Mitchell et al. The ability of an optimized PUVC (248 nm) radiation field on oranges inoculated with Penicillium digitatum spores and exposed to a well-tolerated dose of 2000 mJ cm−2 is shown in Figure 12. PubMed  volume 13, Article number: 16 (2013) Penitrem is produce by species such as Penicillium cyclopium and Penicillium commune. When added to the fungus conidia during the 4 weeks prior to the picking-ripe stage the exudates significantly increased the aggressiveness of the pathogen on plum and nectarine fruits. He had been an office worker for 40 years and had never been involved in agriculture. Comparison of control (right) and PUVC (248 nm) excimer laser-treated (left) oranges inoculated with ∼2×104 cfu of Penicillium digitatum at ∼5 mm under the epidermis. The patient’s vital capacity (VC) of 2.64 L, percentage VC of 85.7%, forced expiratory volume in 1 s (FEV1) of 1.09 L, and percentage FEV1 of 50.9% in August 2005 was lower than his VC of 3.01 L,%VC of 95.6%, FEV1 of 1.12 L,%FEV1 of 49.6% in 2003.

California Privacy Statement, Applying mixtures of O2 and CO to B. cinerea-inoculated apples inhibited lesion development, and the inhibition was closely related to the decrease in the O2 level from 8% to 2% (Sommer et al., 1981). On the other hand, a synthetic mixture of limonene, the major terpene in the wounded fruit atmosphere, with acetaldehyde, ethanol and CO2, at concentrations similar to those measured in the atmosphere around wounded oranges, stimulated spore germination on water agar to the same degree as the natural mixture of volatiles. By using this website, you agree to our Penicillium digitatum is the most destructive postharvest pathogen of citrus fruits, causing fruit decay and economic loss. Fungal resistance to these chemicals, along with consumer pressure for safer control methods is providing the impetus for alternative treatments based on generally regarded as safe compounds in combination with heat treatments and biological control agents, such as naturally occurring bacteria and yeasts. 1995, 61: 1323-1330. PubMed  This period corresponds with the large increase in sugar content of the exudates, along with the increased susceptibility of grapes to infection (Kosuge and Hewitt, 1964; Padgett and Morrison, 1990). Penicillium marneffei infection found in both immunocompetent and immunosuppressed patients. 2005, 45: 184-207. These factors might have facilitated the infection. Postharvest rots of several fruits could be reduced considerably by spraying the fruit with spores of antagonistic fungi and saprophytic yeasts at different stages of fruit development, or by dipping the harvested fruit in the inoculum. CAS  Penicillium species are one of the most common causes of spoilage of fruits and vegetables.For example, Penicillium italicum and Penicillium digitatum are frequent causes of rot of citrus fruits, while Penicillium expansum is known to spoil apples and {798, 2539,3090}. PubMed Central  9-18B), and Rhizoctonia rots. 3). Citral exhibits strong antifungal activity against Penicillium digitatum.In this study, 41 over-expressed and 84 repressed proteins in P. digitatum after 1.0 μL/mL of citral exposure for 30 min were identified by the iTRAQ technique. However, in immunocompromised hosts they can be virulent pathogens and can cause death. Penicillium The fungus coils over hyphae and conidia of its host and kills them (Peresse and Le Picard 1980) with a fungistatic sesquiterpene metabolite, deoxyphomenone (Tirilly et al. Chest. The major components of this mixture were the terpenes, limonene, ∝-pinene, β-myrcene, and sabinene, accompanied by acetaldehyde, ethanol, ethylene and CO2, as identified by gas chromatography (Fig. A mold allergy can make you cough, make your eyes itch and cause other symptoms that make you miserable. However, when a comparable amount of isolated lemon peel oil was topically applied to the washed wounds, 92% of the inoculated wound sites did develop complete green mold symptoms (Arimoto et al., 1995). 1. Ripening apricots also release ethanol and acetaldehyde which, at low concentrations, stimulate germ tube growth of Monilinia fructicola, in vitro (Cruickshank and Wade, 1992). from this patient have a brush-like appearance; the spores of A British study determined that Aspergillus- and Penicillium-type spores were the most prevalent in the indoor air of residential properties, and exceeded outdoor levels. Article  When added to air, CO increased the CO2 and ethylene production rates and, in parallel, hastened the ripening of mature-green tomatoes, while the addition of CO to a low – O2 atmosphere had no or very little effect on these physiological responses. Here, we report a case of fatal pneumonia due to P. digitatum infection, as confirmed by repeated examination of cultured sputum. 1986, 1987). Privacy Penicillium digitatum is widely distributed in soils throughout the world. PubMed  MW and YK confirmed the fungus as P. digitatum by molecular identification. The three enzymes are considered to be potentially important in host resistance mechanisms: chitinase and β-1,3-glucanase are hydrolases, capable of hydrolyzing fungal cells (Schlumbaum et al., 1986; Wilson et al., 1994), while peroxidase is involved in lignin formation and the production of structural barriers against pathogens (El Ghaouth et al., 1998; Chittoor et al., 1999). The ascomycete Letendraea helminthicola parasitizes the hyphomycete Helminthosporium velutinum (Ellis and Ellis 1988). 1997, 35: 2654-2656. Fig. Sometimes the food people consume can be unsafe. A.D. Hocking, in Encyclopedia of Food Microbiology (Second Edition), 2014. The fungi gain entry if fruit is damaged during handling and storage, and then decay can spread from fruit to fruit. Volatile compounds that stimulate spore germination or fungal development were suggested by French (1985) to act by altering membrane permeability or regulating metabolism. However, the cavity became larger and thicker-walled (Figure 1c, July 2005), and the patient developed back pain. Ouchterlony O: Antigen-antibody reactions in gels. In potato tubers a close connection was found between the reducing sugar content and the susceptibility of the tuber to bacterial soft rot during storage at various temperatures (Otazu and Secor, 1981). In his case, antimycotics were ineffective in treating the lung involvement. AfpB is a recently identified AFP in the genome of the citrus postharvest pathogen Penicillium digitatum . The yeast Clavispora lusitaniae 146 has previously been shown to efficiently protect lemons from green mold caused by Penicillium digitatum. PubMed  All authors read and approved the final manuscript. We declare no financial support. Nevertheless, three general features, their formation in ribosomes, their activity at low concentrations (in the nanomolar range), and their narrow spectrum of action, permit one to differentiate bacteriocins from antibiotics. The investigators believe that weed pollens with high sugar contents are likely to lead to further stimulation of the pathogen on fruit in the orchard (Fourie and Holz, 1998). After exposure to fludioxonil, glycerol concentrations significantly increased in the sensitive and MR isolates, but not in the HR isolate. Untreated peaches (right) became severely rotten within 8 days from inoculation with M. fructicola, Anuja Bhardwaj, Kshipra Misra, in Management of High Altitude Pathophysiology, 2018. That is why intensive research is being done in order to come up with a lasting food security solution. Google Scholar, The pre-publication history for this paper can be accessed here:http://www.biomedcentral.com/1471-2466/13/16/prepub. Since Penicillium molds are fungi, their tiny spores can become airborne easily and linger in the air without us knowing it. This defect is not always obvious externally, but manifests as an internal blackening of the fruit. The presence of antigen-specific precipitating antibodies to Aspergillus flavus and P. digitatum was confirmed in the patient’s serum and also later pleural fluid by using Ouchterlony double immunodiffusion testing with A. flavus and P. digitatum antigens.

Patients with Penicillium species infections have been treated successfully with itraconazole [8], amphotericin B [3, 9], or fluconazole [3]. Once the citrus Penicillium became established in the apple, it progressed at a higher rate than that of the apple Penicillium. Edlich et al. Proceedings of the Florida State Horticultural Society, 93:305-307. 10.1097/00007611-199006000-00029. In April 2005, our patient had precipitins against both P. digitatum and A. flavus, but we did not find any P. digitatum or A. flavus in sputum cultures or in bronchoalveolar lavage fluids. Fig. Wild and Wilson (1996) have recently detected a host defense reaction in apples, which reduced decay development in fruits that had been challenged by Penicillium expansum, the typical blue mold fungus of apples. Article  To our knowledge, this is the first report of pulmonary infection with P. digitatum. In comparison to other detection assays, the latex agglutionation assay exceeds the … Studies with unripe avocado fruits indicated that their resistance to anthracnose, caused by Colletotrichum gloeosporioides, was related to the presence of an antifungal diene compound in the peel (Prusky and Keen, 1993). The disinfection effectiveness of high-power PUVC combined with diffuse all- direction exposure fields can be summarized in a few selected examples from laboratory experimentation. Mok T, Koehler AP, Yu MY, Ellis DH, Johnson PJ, Wickham NW: Fatal Penicillium citrinum pneumonia with pericarditis in a patient with acute leukemia. Conidia germination and germ tube growth of Penicillium digitatim in 1% (v/v) orange juice dialysate at several pH values. Although human infections with P. digitatum are considered rare, it appears that this organism can be very virulent and resistant to antimycotics. GEORGE N. AGRIOS, in Plant Pathology (Fifth Edition), 2005. NT examined the patient, took part in discussions about the patient, and was involved in manuscript preparation and editing. 2). In this study, 41 over-expressed and 84 repressed proteins in P. digitatum after 1.0 μL/mL of citral exposure for 30 min were identified by the iTRAQ technique. One such yeast, Candida saitoana, controlled postharvest decay of apple fruit by inducing systemic resistance in apple fruit while at the same time increasing chitinase and β-1,3-glucanase activities in the fruit. He was admitted to our hospital on 25 July 2005 and was treated for 3 months with an increased dose of itraconazole (200 mg/day) with added micafungin (300 mg/day). The proteins were closely related … It can be contaminated with a lot of components such as fung… At the time the patient did not have increased sputum production, but chest computed tomography (CT) revealed a thin-walled cavity about 4 cm across and containing a fungus ball in the left upper lobe (S1 + 2); a CT scan taken 2 years previously had revealed only a small cavity indicative of emphysematous change (Figures 1a, 1b). Aw 0.78 - 0.88 (5) A wide number of organisms have placed in this genera. The entomogenous Hirsutella citriformis, a destructive parasite of brown planthoppers on the Solomon Islands, was colonized by Calcarisporium (Cladobotryum) ovalisporum; because this fungus requires sterilized host hyphae to grow on agar media, it also may be dependent on the fungal metabolite mycotrophein (Rombach and Roberts 1987). Moreover, a mixture of these two compounds had a synergetic effect, leading to high germination rates in the conidia population (French et al., 1978). On first presentation in April 2005 to our hospital, he did not have asthma exacerbation or increased sputum production, but his dyspnoea on effort was graded 2 on the Hugh–Jones scale. On the other hand, washing wounded lemon fruit peel (epicarp) was found to greatly suppress P. digitatum infection, when the fruit was inoculated with fungal spores, so that only 2% of the fruit showed green mold symptoms. Observation was after 2 days of treatment. (1989) found that certain sugars taken up by B. cinerea could stimulate fungal growth and enhance its infection capability, but suggested that the stimulation was due to the active oxygen formed rather than to a nutritional effect. Challenge inoculation with the avocado pathogen, C. gloeosporioides (Prusky et al., 1990), or with a non-pathogenic mutant of Colletotrichum magna (Prusky et al., 1994) led to increased levels of the antifungal diene. This yeast also acts similarly against Rhizopus stolonifer, Botrytis cinerea, and Alternaria alternata on tomatoes and grapes. Metschnikowia fructicola-Penicillium digitatum (Mf-Pdig) interaction To obtain an even mycelial mat of P. digitatum on PDA, 1 ml of fungal spore suspension (1 × 10 4 spores ml -1 ) was thoroughly mixed with 9 ml molten 1% PDA (cooled down to about 40°C) in a petri dish and allowed to … Spores of Penicillium digitatum, the green mold fungus which attacks only citrus fruit, germinate to a minor extent in pure water, whereas the addition of fruit juice greatly accelerates germination (Pelser and Eckert, 1977). Biocontrol, that is, the use of microorganisms to inhibit plant pests, offers in this ambit an attractive option to chemical pesticides.8, Not only fungi, however, but numerous microorganisms have been identified that suppress plant pathologies both in the laboratory and in field experiments, but only few of these agents are effective over a broad range of conditions. The antagonistic yeast, Pichia guilliermondii, which is effective in controlling a wide variety of postharvest diseases in citrus fruits, apples and peaches, has been shown to induce enhanced levels of phenylalanine ammonia lyase (PAL) in citrus fruit peel (Wisniewski and Wilson, 1992), indicating the induction of a defensive response. 3. 1968, New York: Hafner Publ. Early studies with B. cinerea showed that distilled water on the surfaces of leaves and petals contains more electrolytes than distilled water on glass slides, and that spores of Botrytis usually germinate better in water containing electrolytes (Brown, W., 1922a). The fruiting structures (penicilli) of Penicillium from this patient have a brush-like appearance; the spores of Penicillium digitatum are typically elliptical under the microscope. Aspergillus luchuensis and a diversity of other fungi are parasitized in India by Fusarium udum (Upadhyay et al. # 93546-NE-001 . A greatly enhanced germination is stimulated by the ascorbic acid, whereas the citric acid has no stimulating effect. The patient was unable to undergo further lung function tests because of his progressive respiratory failure. And because we all need to breathe, we are likely to inhale these spores if there is a mold contamination in our home. Penicillium species can cause opportunistic infections [2]. 9. In the presence of 250 ppm oil, 15% of the spore population had germinated after 24 hours at 19°C, while no germination occurred in the control spores (water only). Gelfand MS, Cole FH, Baskin RC: Invasive pulmonary penicilliosis: successful therapy with amphotericin B. PubMed Central  (C) Peaches at left were protected from infection by the brown rot fungus (Monilinia fructicola) by prior treatment with the nonpathogenic bacterium Bacillus subtilis. Penicillium digitatum, Geotrichum candi-dum, postharvest decay Abstract. Studying the effects of various atmospheres on the severity of watery soft rot of celery caused by Sclerotinia sclerotiorium, Reyes (1988) found that whereas a low-O2 CA (1.5%), with or without high CO2 (16%), reduced decay development only slightly, a combination of 7.5% CO + 1.5% O2 suppressed disease significantly without causing undesirable effects on celery quality. Penicillium growth can still occur indoors even if the relative humidity is low, as long as there is sufficient moisture available on a given surface. G. lucidum extract showed higher activity against S. aureus and B. cereus than the antibiotics ampicillin and streptomycin in a study by Heleno et al. Pfaller MA, Messer SA, Hollis RJ, Jones RN, SENTRY Participants Group: Antifungal activities of posaconazole, ravuconazole, and voriconazole compared to those of itraconazole and amphotericin B against 239 clinical isolates and Aspergillus spp. We confirmed the presence of antigen-specific precipitating antibodies to P digitatum by using antigen derived from the patient’s sputum culture fluid or extracted directly from his sputum (Figure 3b). Citral exhibits strong antifungal activity against Penicillium digitatum. MC Lagunas-Solar, in Encyclopedia of Food Safety, 2014. statement and 1976; Tsuneda and Skoropad 1978, 1980), which forms coils and appressoria and sometimes penetrates the host hyphae. However, some patients with conditions caused by Penicillium species have died despite treatment with ketoconazole [2], amphotericin B [2], or itraconazole [10]. In some people, mold allergy is linked to asthma and exposure causes restricted breathing and other airway symptoms.If you have a mold allergy, the best defense is to reduce your exposure to the types of mold that cause your reaction. Figure 13. Fig. Penicillium spore germination is also stimulated by the addition of oil derived from the rind of orange, lemon, grapefruit or other citrus fruits (French et al., 1978). Eckert and Ratnayake (1994) found that a mixture of limonene, acetaldehyde, ethanol, CO2 and other volatile compounds emanating from wounded oranges induced germination of P. digitatum conidia on water agar.
