penicillium digitatum inhalation

PubMed Google Scholar. It was then incubated with 0.125 mol of NH4CO3 overnight at 4°C and the antigen extracted after freeze-drying of the filtrate. 1989); in high concentrations, the parasite inhibits the conidial germination and hyphal growth of its host, apparently through competition for nutrients. Penicillium species are among the most common fungi in the environment and are usually considered non-pathogenic to humans [1]. Barmore CR, Brown GE, 1982. In that connection, a lot of components are used to create new food supplements, genetically engineered foods, and great food alternatives. It is interesting to note that volatile compounds evolved from diced peels of various Citrus spp. The patient was treated over a period of months with itraconazole, micafungin, voriconazole, amphotericin B, and antibacterials. 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. Figure 12. We diagnosed the patient with lung aspergilloma and treated with itraconazole (100 mg/day) for 3 months. Penicillium digitatum is a plant pathogen that commonly causes a postharvest fungal disease of citrus called green mould; it very rarely causes systemic mycosis in humans. A 78-year-old male presented at our hospital in April 2005 with a history of bronchial asthma and pulmonary emphysema first diagnosed at age 66 years. Chen KY, Ko SC, Hsueh PR, Luh KT, Yang PC: Pulmonary fungal infection. 1. 1 displays the stimulating effect of various concentrations of oil produced from an orange rind on the germination rate of P. digitatum conidia. Searching for the reason for this phenomenon, Eckert and Ratnayake (1994) found that a mixture of volatiles evaporating from the abrasions of wounded oranges were capable of accelerating or inducing germination of P. digitatum spores on water agar as well as within an injury of the rind. The addition of high CO2 to this atmosphere further enhanced fungal growth inhibition, because of the additive effects of CO and CO2 (El Goorani and Sommer, 1979,1981). 2002, 46: 1032-1037. 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). Fatal pneumonia caused by Penicillium digitatum: a case report. In his case, antimycotics were ineffective in treating the lung involvement. Article  These factors might have facilitated the infection. Upon Ouchterlony double immunodiffusion testing, the sera of five of 770 patients with pulmonary lung disease were confirmed to have low titres of antigen-specific precipitating antibodies to P. digitatum against antigen (obtained from Greer Laboratories, Lenoir, NC). 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. 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). Alternaria species can cause black center rot of oranges and mandarins. 10.1159/000237283. Since Penicillium molds are fungi, their tiny spores can become airborne easily and linger in the air without us knowing it. 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. People are commonly exposed to the spores of this airborne pathogen every day. Proceedings of the Florida State Horticultural Society, 93:305-307. GEORGE N. AGRIOS, in Plant Pathology (Fifth Edition), 2005. Here, we report a case of fatal pneumonia due to P. digitatum infection, as confirmed by repeated examination of cultured sputum. No A. flavus or P. digitatum and no bacteria or tubercle bacilli were detected in cultures of sputum or bronchial lavage fluids. PubMed  Article  Correspondence to 1981), which produces a diffusible toxin and induces vesicular deformations in its host. 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). Diffuse reflectance occurs from waxy, round surfaces, but the ablation effects remove the debris (soil dust and pesticide residues). AfpB is a recently identified AFP in the genome of the citrus postharvest pathogen Penicillium digitatum . The fruiting structures (penicilli) of PubMed  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. 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. EPA Registered Name Bio-Safe. Phytopathology, 72(1):116-120 J Clin Microbiol. Here, we report a case of fatal pneumonia due to P. digitatum infection, as confirmed by repeated examination of cultured sputum. Volatile compounds that stimulate spore germination or fungal development were suggested by French (1985) to act by altering membrane permeability or regulating metabolism. CAS  In humans there is cross-reactivity to Aspergillus and Penicillium: most sera from patients with precipitins against Penicillium have precipitins against Aspergillus [7]. Google Scholar. 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. 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). Green mold, caused by Penicillium digitatum, is the most economically important postharvest disease of orange fruit worldwide. A greatly enhanced germination is stimulated by the ascorbic acid, whereas the citric acid has no stimulating effect. Glass NL, Donaldson GC: Development of primer sets designed for use with the PCR to amplify conserved genes from filamentous ascomycetes. Cookies policy. Chest. Commonly found in soil, food, cellulose and grains (17, 5). Conidia germination and germ tube growth of Penicillium digitatim in 1% (v/v) orange juice dialysate at several pH values. 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 genus was first identified in scientific literature by Johann Heinrich Friedrich Link in his 1809 work Observationes in ordines plantarum naturale. Penicillium digitatum Medications can help keep mold allergy reactions under control. Often found in aerosol samples (17). Penicillium is among the five most common genera in the outdoor and indoor fungi aerosols {2649, 2747, 2759}. Google Scholar. BMC Pulm Med 13, 16 (2013). Antigen-specific precipitating antibodies to Aspergillus flavus and Penicillium digitatum in the patient’s serum (a) were found by Ouchterlony double immunodiffusion testing with A. flavus and P. digitatum antigens. 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. If you have a mold allergy, your immune system overreacts when you breathe in mold spores. Cite this article. After exposure to fludioxonil, glycerol concentrations significantly increased in the sensitive and MR isolates, but not in the HR isolate. 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. their compositions, hence the relative differences among the stimulating or suppressing activities of oils produced from different sources. Aspergillus luchuensis and a diversity of other fungi are parasitized in India by Fusarium udum (Upadhyay et al. Mycotoxins such as alternariol (AOH) and alternariol monomethyl ether (AME) may be associated with Alternaria rots in citrus. This area was suggested to be the location in which the host defense reaction occurred (Wild and Wilson, 1996). Our patient had pulmonary emphysema and was elderly, and undernourished. PubMed Central  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. This fungus was confirmed to be P. digitatum by molecular identification. The patient’s medication regimen was changed to voriconazole (400 mg/day), amphotericin B (10 mg/day), and fluconazole (400 mg/day), in addition to itraconazole (200 mg/day) and antibacterials. Fungal spores can rapidly degrade this acid to 2,3-dihydroxybenzoic acid, which is responsible for the accelerated germination. Barmore CR, Brown GE, 1980. In addition, the yeast Candida oleophila was approved for postharvest decay control in citrus and apples under the trade name Aspire. Penicillium digitatum is the most devastating pathogen of rotten citrus fruit and is responsible for 90% of production losses during post-harvest handling [ 6 ]. 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. Inoculum was injected ∼5 mm deep (in three sites) and represented a common practical problem as wounded, deep infection sites can normally develop into larger infections and are inaccessible to sprayed pesticides or fumigants. Penicillium digitatum is the most destructive postharvest pathogen of citrus fruits, causing fruit decay and economic loss. (1995) investigated the possibility that some components of the lemon peel oil might be essential for fungal development in the peel tissues. Our patient had pulmonary emphysema and was elderly, and undernourished. 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. Penicillium digitatum is a plant pathogen that commonly causes a postharvest fungal disease of citrus called green mould [1]; it very rarely causes systemic mycosis in humans [3]. (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. A similar effect occurred on Penicillium italicum conidia also. (1978) showed that the addition of CO (5 or 10%) to a low-O2 atmosphere (4%) reduced the incidence and severity of the gray mold decay in Botrytis cinerea-inoculated tomatoes at their mature-green or pink stage. 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. Penicillium funiculosum can smother various fungi in culture and thus prevent pineapple fruit diseases (Lim and Rohrbach 1980). Penicillium digitatum, Geotrichum candi-dum, postharvest decay Abstract. 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). Manage cookies/Do not sell my data we use in the preference centre. Figure 13. Fig. Below are the links to the authors’ original submitted files for images. 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. 1. From sputum culture only one fungus was isolated repeatedly on potato-dextrose agar in large quantities. 1949, 26 (4): 507-515. Google Scholar, The pre-publication history for this paper can be accessed here:http://www.biomedcentral.com/1471-2466/13/16/prepub. The biotrophic Debaryomyces hansenii can control penetration of citrus fruit by Penicillium digitatum (Droby et al. In his case, antimycotics were ineffective in treating the lung involvement. This includes soil particles and pesticide residues. are typically elliptical under the microscope. Partial sequences of the β-tubulin gene determined by using the primers Bt2a and Bt2b [5] underwent BLAST analysis at the National Centre for Biotechnology Information. At 25–30 °C, fruit will rot completely in 4 or 5 days, and the disease can spread by contact. Penicillium digitatum and Geotrichum candidum are 1997, 35: 2654-2656. Testing the effect of the juice components on spore germination revealed that of the sugars within the juice (glucose, sucrose and fructose), glucose is the best stimulant. Partial sequences of the beta-tubulin gene were determined by using the primers Bt2a and Bt2b for PCR amplification and sequencing and underwent a BLAST search at the National Centre for Biotechnology Information, these results confirmed that the isolated fungus was P. digitatum. 1976; Tsuneda and Skoropad 1978, 1980), which forms coils and appressoria and sometimes penetrates the host hyphae. Cavitation refers to a physical process in which increased UV penetration is obtained due to the multiple scattering of photons from diffuse reflecting surfaces including waxy fruit surfaces. There were no inflammatory changes in the peripheral blood (leukocyte count, 7950 cells/μL; C-reactive protein, 0.23 mg/dL; erythrocyte sedimentation rate, 10 mm/h; Aspergillus antigen, negative; β-D glucan, negative), but antigen-specific precipitating antibodies to Aspergillus flavus and P. digitatum were confirmed in the patient’s serum and pleural fluid by Ouchterlony double immunodiffusion testing [4]. P. guilliermondii, as well as an isolate of the yeast Candida famata, which is similarly effective against Penicillium digitatum in citrus fruits (Arras, 1996), contributes to enhanced host resistance by inducing the formation of the phytoalexin scoparone or of scoparone plus scopoletin, respectively, in the fruit peel (Rodov et al., 1992; Arras, 1996). In comparison to other detection assays, the latex agglutionation assay exceeds the … The terpenes alone, in several concentrations and combinations, failed to stimulate spore germination significantly above its level on water agar. Raper KB, Thom C: Penicillium digitatum. Isolates of Penicillium digitatum, cause of citrus green mould, were collected in California from infected fruit from packing houses or groves. The fractured cells in the injured area also supply the nutrients required for the germination and infection phases. Oshikata, C., Tsurikisawa, N., Saito, A. et al. The panel included Penicillium digitatum, Penicillium italicum, Rhizopus stolonifer, Botrytis cinerea and Monilinia fructicola, all of which cause relevant economic losses worldwide as a result of affecting harvested fruits. 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). Another common postharvest problem of citrus is sour rot, caused by the yeastlike fungus, Geotrichum candidum. Pollen exudates from weeds commonly found in stone fruit orchards have also been found to be stimulators of B. cinerea growth (Fourie and Holz, 1998). Pulmonary infections with fungi, including Penicillium species, are associated with much higher mortality rates in patients with nosocomial infections or infections complicating organ failure [11]. PubMed  The application of the protein synthesis inhibitor, cycloheximide prevented the reaction and resulted in more than 700% increase in decay. 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). 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). However, on the surface of banana fruits, both spore germination and the formation of appresoria (specific resting spores responsible for fruit infection) were accelerated (Swinburne, 1976).

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). Article  Penicillium digitatum is a plant pathogen that commonly causes a postharvest fungal disease of citrus called green mould [1]; it very rarely causes systemic mycosis in humans [3]. [12]. 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. A cavity was found in the left upper lung on routine chest X-ray in a 78-year-old undernourished male who had been diagnosed at age 66 with bronchial asthma and pulmonary emphysema. To our knowledge, this is the first report of pulmonary infection with P. digitatum. 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. 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). The food sector is very important. However, some patients with conditions caused by Penicillium species have died despite treatment with ketoconazole [2], amphotericin B [2], or itraconazole [10]. In a search for parasites of Macrophomina phaseolina (synonym Rhizoctonia bataticola), Arachniotus species and Aspergillus aculeatus were found to be promising control agents (Dhingra and Khare 1973). 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). 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. 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. Penitrem is produce by species such as Penicillium cyclopium and Penicillium commune. Effect of orange oil suspension in 1% water agar on germination of conidia of Penicillium digitatum. MW and YK confirmed the fungus as P. digitatum by molecular identification. PubMed  3). [1] … This yeast also acts similarly against Rhizopus stolonifer, Botrytis cinerea, and Alternaria alternata on tomatoes and grapes. ], Ganoderma sp. 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). 2001, 120: 177-10.1378/chest.120.1.177. The cavity continued to enlarge further. In spite of the efficiency of CO combined with Iow-O2 atmospheres in decay suppression, the use of this gas is limited, mainly because of its high toxicity to humans and the fear of inhalation of the poisonous gas by workers. The effectiveness of this fungistatic gas is pathogen dependent and is greatly enhanced in combination with a low-O2 atmosphere (2.3%). 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). WALTER GAMS, ... KADRI PÕLDMAA, in Biodiversity of Fungi, 2004. 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). The authors declare that they have no competing interests. statement and Management of crop health is in fact essential to agriculture. 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. Google Scholar. 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). Fig. He died from progressive renal failure. The efficacy of thin-film diamond coated electrodes (DiaCell 101) for disinfection of water artificially contaminated with Penicillium digitatum and Pseudomonas spp. In April 2005, when the patient was 78 years old, an abnormal shadow representing a cavity was found in the left upper lung on chest X ray at his yearly medical check-up. Although human infections with P. digitatum are considered rare, it appears that this organism can be very virulent and resistant to antimycotics. Phytopathology. was tested. 1986, 1987).
