In the light of the finding that peel oil extracts applied to wounded epicarps can restore disease development potential to the pathogen, Arimoto et al. Case presentation Copyright © 2020 Elsevier B.V. or its licensors or contributors. This led to a delay in diagnosis. Part of Medications can help keep mold allergy reactions under control. Various solvent extracts of G. lucidum have demonstrated antibacterial activity against Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Bacillus subtilis, Salmonella typhi, and Pseudomonas aeruginosa (Quereshi et al., 2010). Since Penicillium molds are fungi, their tiny spores can become airborne easily and linger in the air without us knowing it. The pleural effusion increased, and the patient began producing purulent sputum. https://doi.org/10.1186/1471-2466-13-16, DOI: https://doi.org/10.1186/1471-2466-13-16. Fatal pneumonia caused by Penicillium digitatum: a case report. Observation was after 2 days of treatment. 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). Ascorbic acid and a number of terpene compounds in citrus fruits, much like their stimulating effect on the germination of P. digitatum spores, can also stimulate mycelial growth of this fungus, which is specific to citrus fruits (Pelser and Eckert, 1977; French et al., 1978). (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. The yeast Clavispora lusitaniae 146 has previously been shown to efficiently protect lemons from green mold caused by Penicillium digitatum. The polysaccharides derived from G. lucidum have been found effective against harmful food-spoiling microorganisms, including Bacillus cereus, B. subtilis, E. coli, Aspergillus niger, and Rhizopus nigricans, and plant pathogens such as Erwinia carotovora, Penicillium digitatum, and B. cinerea (Bai et al., 2008). A mold allergy can make you cough, make your eyes itch and cause other symptoms that make you miserable. 1976; Tsuneda and Skoropad 1978, 1980), which forms coils and appressoria and sometimes penetrates the host hyphae. He had been an office worker for 40 years and had never been involved in agriculture. PubMed Central  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. Germination of various fungal spores may be stimulated by solutes that diffuse from within the fruit or other plant organs into the water film over the infection site. PubMed  The fungicide sensitivity of 166 isolates to imazalil (IMZ), thiabendazole (TBZ), sodium ortho-phenylphenate (SOPP), and pyrimethanil (PYR) were determined. Our patient had pulmonary emphysema and was elderly, and undernourished. As an example, yeasts belonging to the genus Metschnikowia may release pulcherrimin, an antibiotic substance that is able to inhibit several bacterial and fungal species and that is currently used, therefore, to control postharvest pathogens. 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. 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). 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). That is why intensive research is being done in order to come up with a lasting food security solution. 2). 1989); in high concentrations, the parasite inhibits the conidial germination and hyphal growth of its host, apparently through competition for nutrients. Article  In Varanasi, India, Colletotrichum dematium is parasitized by Acremonium sordidulum, which smothers the host and reduces its sporulation on the plant (Singh et al. Here, we report a case of fatal pneumonia due to P. digitatum infection, as confirmed by repeated examination of cultured sputum. J Clin Microbiol. Hsu JH, Lee MS, Dai ZK: Life-threatening airway obstruction caused by penicilliosis in a leukemic patient. 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. 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. In addition, C. guilliermondii is lethal on the tomato root-knot nematode Meloidogyne incognita.69, While B. cereus biocontrol properties rely on zwittermicin A, multiple modes of action support the biocontrol activity of C. guilliermondii. ], Ganoderma sp. Fig. In his case, antimycotics were ineffective in treating the lung involvement. Examination of the various oil component activities revealed that nonanal and citral were the most effective compounds. statement and Also, significant reduction of citrus green mold (caused by Penicillium digitatum) was obtained by treating the fruit with antagonistic yeasts (Fig. The possibility of using CO atmosphere for decay suppression during storage has been studied for various commodities. Here, we report a case of fatal pneumonia due to P. digitatum infection, as confirmed by repeated examination of cultured sputum. His asthma was of the non-atopic type and moderate, as defined by the Global Initiative for Asthma Guidelines 2002. Computed tomographic imaging of the chest at the level of the aortic arch in 2003, two years before dyspnea onset, showed a small cavity in the left upper lobe due to emphysematous change (a). Written informed consent was obtained from the kin of the patient for publication of this Case Report and any accompanying images. Its microscopy can make the o… [12]. Hawksworth (1981a) gives a long list of additional mycoparasites growing on conidial fungi. Biocontrol of the plant-pathogenic Verticillium dahliae has been attempted repeatedly, as reviewed under “Mycoparasites of Mycelia, Ectomycorrhizae, Sclerotia, and Spores in Soil.” Alternaria brassicae, Pleospora species, and Trichothecium roseum are highly susceptible to hyphal interference by Verticillium luteo-album (Tsuneda et al. It was then incubated with 0.125 mol of NH4CO3 overnight at 4°C and the antigen extracted after freeze-drying of the filtrate. Penicillium species can cause opportunistic infections [2]. 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 addition of CO to the atmosphere results in the suppression of various fungi sensitive to the gas, such as Penicillium digitatum, P. italicum and Monilinia fructicola. 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. 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. 1986, 1987). Treatment with this broad range of antimycotics and antibiotics did not slow the growth of the cavity: its fluid content continued to increase, and invasive consolidation and pleural effusion developed (Figure 1e, December 2005; 1f, January 2006). Fungal spores can rapidly degrade this acid to 2,3-dihydroxybenzoic acid, which is responsible for the accelerated germination. However, when P. digitatum spores on water agar were exposed to several wounded oranges in closed containers, germination did take place in the absence of substrate nutrients (Eckert and Ratnayake, 1994). (5) It may cause hypersensitivity pneumonitis, allergic alveolitis in susceptible individuals.

J ANETH F ERNANDEZ AND D AVID J. H ALL 1 Fresh Mark Corporation 662 E. Meyers Blvd. A Manual of the Penicillia. Pulcherrimin, specifically, is a reddish pigment that is able to chelate iron ions, thus immobilizing the metal in the medium where antagonized organisms cannot therefore grow; mutants that do not produce the pigment do not show the antimicrobial activity.45–68 The latter may affect several bacterial and fungal species, including Aspergillus flavus, Aspergillus versicolor, Aspergillus nidulans, Aspergillus ustus, Aspergillus fumigatus, Aspergillus rubrum, Aspergillus terreus, Aspergillus flavipes, Trichophyton mentagrophytes, Trichophyton schoenleinii, Trichophyton violaceum, and Trichophyton tonsurans.45–68, Likewise, some Candida guilliermondii strains exhibit a relevant potential in postharvest biocontrol of spoilage fungi during storage of vegetables and fruit. Turhan (1993) found a number of additional, interesting antagonists of Alternaria alternata, particularly Dicyma olivacea, Stachybotrys elegans, a species of Sesquicillium, five species of Myrothecium, and Coniothyrium sporulosum. Manage cookies/Do not sell my data we use in the preference centre. Others of this species are used in the food making industry specifically in the production of cheese. Kingdom: FungiPhylum: AscomycotaClass: EuascomycetesOrder: EurotialesFamily: TrichomaceaeGenus: Penicillium 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. The application of the protein synthesis inhibitor, cycloheximide prevented the reaction and resulted in more than 700% increase in decay. In addition, the yeast Candida oleophila was approved for postharvest decay control in citrus and apples under the trade name Aspire. PubMed Central  Diffuse reflectance occurs from waxy, round surfaces, but the ablation effects remove the debris (soil dust and pesticide residues). Penicillium marneffei infection found in both immunocompetent and immunosuppressed patients. Here, we report a case of fatal pneumonia due to P. digitatum infection, as confirmed by repeated examination of cultured sputum. The discomycete Bisporella pallescens (synonym Calycella monilifera) fruits densely on the conspicuous black conidial patches of Bispora antennata on tree stumps (Jahn 1968). 10.1159/000237283. volume 13, Article number: 16 (2013) A similar effect occurred on Penicillium italicum conidia also. Various fungi, which penetrate through wounds, encounter the moisture required for germination of their spores in fresh wounds in the cuticle and epidermis of the host. 9. A conidial suspension of this fungus with carboxymethyl cellulose sprayed on P. personata prevented secondary spread of the pathogen under moist conditions (Mitchell et al. 2001, 120: 177-10.1378/chest.120.1.177. The biotrophic Debaryomyces hansenii can control penetration of citrus fruit by Penicillium digitatum (Droby et al. This method has been successful in detecting contamination of grains and processed foods at a limit of detection of 5–10 ng/mL of antigen. The efficacy of thin-film diamond coated electrodes (DiaCell 101) for disinfection of water artificially contaminated with Penicillium digitatum and Pseudomonas spp. Mok T, Koehler AP, Yu MY, Ellis DH, Johnson PJ, Wickham NW: Fatal Penicillium citrinum pneumonia with pericarditis in a patient with acute leukemia. Penicillium ascomycetous fungiare microscopic organisms that are of major importance in the natural environment, in the production of foods and in the pharmaceutical industry. People are commonly exposed to the spores of this airborne pathogen every day. In a recent study, Vazirian et al. Moreover, a mixture of these two compounds had a synergetic effect, leading to high germination rates in the conidia population (French et al., 1978). 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. 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. 10.1097/00007611-199006000-00029. Emphasis on microbiological spectra, patient outcome and prognostic factors. 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). Kader et al. 1990, 83: 701-704. Terms and Conditions, 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. 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. In a recent study, Ippolito et al. These mold species usually grow on foods such as cheese and fruits, and the mycotoxin finds its way toward human’s digestive system through oral consumption. # 93546-NE-001 . PubMed  This acid is involved in the active transport of iron in various microorganisms and reduces the iron level around the spores on the surface of the banana (Harper and Swinburne, 1979; Harper et al., 1980). Limonene peak shown was attenuated 16 times. Privacy 1949, 26 (4): 507-515. 2002, 46: 1032-1037. This yeast also acts similarly against Rhizopus stolonifer, Botrytis cinerea, and Alternaria alternata on tomatoes and grapes. 2. All authors read and approved the final manuscript. Passalora personata also can be parasitized by Cladosporiella cercosporicola (Esquivel-R. 1984). These genetic elements have been implicated in azole resistance in many filamentous fungi due to increased expression of the target gene by increasing promoter activity. Electrolysis process was performed with different operation conditions: current densities at 4, 8, and 12A and water flow rate at 150, 300, and 600 L/h. Ten days later, the germination rate amounted to 70% with the oil, in comparison with approximately 10% in the control. 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. 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 … 1991). This phenomenon explains why siderophores, which are chelating agents with a high affinity for this metal, that are formed on the banana surface by bacteria, under conditions of iron deficiency (Neilands, 1981), stimulate and accelerate germination of Colletotrichum spores and the formation of appresoria (McCracken and Swinburne, 1979). Raper KB, Thom C: Penicillium digitatum. 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. To our knowledge, this is the first report of pulmonary infection with P. digitatum. Penicillium digitatum, Geotrichum candi-dum, postharvest decay Abstract. (B) Apples 3 months after they had been wounded and inoculated with fungi Penicillium and Botrytis with (right) or without (left) treatment with the biocontrol bacterium Pseudomonas syringae (BioSave 110). Acta Pathol Microbiol Scand. CAS  Chen KY, Ko SC, Hsueh PR, Luh KT, Yang PC: Pulmonary fungal infection. It was identified as P. digitatum and had the form of a spreading organism with a mealy, grey-green colour that turned olive green in culture. J Clin Microbiol. 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.
