penicillium expansum disease

Many molds are harmful to human health, especially to infants, those with respiratory conditions such as asthma, elderly people as well as those with poorly functioning immune systems. Joanna Tannous, Omer Barda, Dianiris Luciano-Rosario, Dov B. Prusky, Edward Sionov, Nancy P. Keller, New Insight Into Pathogenicity and Secondary Metabolism of the Plant Pathogen Penicillium expansum Through Deletion of the Epigenetic Reader SntB, Frontiers in Microbiology, 10.3389/fmicb.2020.00610, 11, (2020). Penicillium expansum is one of the most harmful post-harvest pathogens of pomaceous fruits and the causal agent of blue rot disease. other than P marneffei occurs almost exclusively among profoundly immunosuppressed patients and is exceedingly rare. If you are experiencing any of the above-mentioned symptoms and you suspect that mold is the cause, it’s advisable to see your doctor. Some people may also experience rashes or hives as well as swelling in the throat, which can be a life-threatening reaction known as anaphylaxis. There are currently no serological tests to diagnose P marneffei infection. Anemia is the most common laboratory abnormality present and is found in approximately three-quarters of patients. Mold, septate hyphae 1.5-5 um in diameter. The United States also played a significant role in the large-scale production of Penicillium during World War II, thereby making the life-saving substance that was once in limited supply widely available. The disease also closely resembles histoplasmosis and cryptococcosis as it occurs in HIV-infected patients. Penicillium expansum has a wide host range, causing similar symptoms on fruits which include apples, pears, cherries, and citrus . Generalized lymphadenopathy is also often present. Its significance has increased in recent years because it produces a mycotoxin, patulin, which occurs in Penicillium-rotted fruit and subsequently in fruit juice produced from reject fruit. Habitat utama dari P. expansum adalah patogen dekstruktif pada buah pome. The identification of these species is based on their microscopic features and macroscopic morphology. Blue mold is the most important postharvest disease of apples and pears worldwide and in the Pacific Northwest (Amiri and Ali, 2016; Rosenberger, 1990). Without a doubt, any identified mold should be removed from your home—the sooner the better. ©Anna L. Snowdon It is also found in paint and compost piles. Like all molds, Penicillium can develop whereever there is moisture and a temperature that is conducive for its growth. Blue mold. is one of the most common global and economically important postharvest fruit rot diseases (Zhong et al., 2018). In this study, Penicillium expansum was isolated from naturally infected apple fruits and identified by morphological observation and rDNA‐internal transcribed spacer analysis. Infection caused by Penicillium spp. This is the reason why many homeowners make the decision to hire a mold removal professional to safely eliminate the mold problem. P. expansum also produces an array of mycotoxins that are detrimental to human health. Some produce antibiotics, some can be opportunistic pathogens, and some produce mycotoxins. The blue mould decay of apples is caused by Penicillium expansum and is associated with contamination by patulin, a worldwide regulated mycotoxin. (Pianzzola et al., 2004); it produces a mycotoxin with neurotoxic functions on apple fruits (Brause et al., 1996). In addition, recovery from a sterile body fluid such as blood or synovial fluid is suggestive of infection but must be interpreted with caution in view of the frequency with which Penicillium spp. (2). Penicillium molds feed off of water, humidity or any other type of moisture. PgAFP produced by Penicillium chrysogenum can inhibit the growth of several P. expansum strains in vitro, and reduce disease incidence and severity in Royal Gala apples (Delgado et al., 2019). Relapse rarely occurs in immunocompetent patients but is common among AIDS patients. The blue mould fungus negatively affects fruit quality, thereby reducing fresh fruit consumption, and significantly contributes to food loss. A standard course of therapy is 2 weeks of amphotericin followed by 6 weeks of itraconazole. It was Penicillium mold that was responsible for saving many lives by producing the first known modern antibiotic known as penicillin. Penicillium expansum sebagai Foodborne Disease Salah satu spesies tertua dari Penicillium , adalah P. expansum. GENOME ANNOUNCEMENT. Vegetative Structure of Penicillium 3. A nonproductive cough is frequently present. (10) Another example, as mentioned earlier, is the penicillin drug, produced by P. chrysogenum, which is frequently found in many households. Published: August 19, 2018 Updated: April 1, 2019, Written by: John Ward Account Executive Mold Busters, Fact checked by: Charles Leduc CPI, CMI, CMR Mold Busters. In Thailand, penicilliosis is the third most common opportunistic infection in patients with AIDS. This species profile comprises a comprehensive literature review of this aggressive pathogen associated with pomes (apple, pear, quince), focusing on biology, mechanisms of disease, control, genomics, and the newest developments in disease management. Penicillium ear rot and blue eye Penicillium spp. The following is a list of the personal protective equipment you should wear when cleaning mold: Once you have removed all Penicillium molds from your home, you need to prevent them from growing back. As such, the health of the building’s occupants can be adversely affected if the indoor environment contains high concentrations of Penicillium. Inspection for Cannabis Growing Facilities, exposure to this mold is not good for human health, American academy of allergy asthma & immunology. Blue and gray mold caused by Penicillium expansum and Botrytis cinerea, respectively are the most prominent postharvest diseases on pome fruit. Over the years, a great deal of effort has been put into establishing standards for safe levels of mold spores in indoor residential environments. Blood cultures will establish the diagnosis, but other specimens including bone marrow, skin, abscess fluid, lymph nodes, sputum, and others may yield the organism. Some produce antibiotics, some can be opportunistic pathogens, and some produce mycotoxins. Usually, puncturing, bruising and limb rubs occur during harvesting, packaging, and processing of the fruit all of which are sites the spores can enter the fruit. On occasion, a more suppurative reaction can occur in immunocompetent patients, resulting in abscess formation in various organs, especially the lung, skin, liver, and subcutaneous tissues. Penicillium expansum sebagai Foodborne Disease Salah satu spesies tertua dari Penicillium, adalah P. expansum. The word penicillus is Latin for paintbrush. (5) It may cause hypersensitivity pneumonitis, allergic alveolitis in susceptible individuals. Difenoconazole (DIF) is a new demethylation inhibitor (DMI) fungicide registered recently to manage postharvest diseases of pome fruit. Colletotrichum gloeosporioides and Penicillium expansum cause postharvest diseases in tropical and deciduous fruit. They are present in soil, […] Rot start as a soft, light-colored spot that spreads rapidly across the surface and deeply into the fruit tissue, with blue … Penicillium expansum is one of the main pathogens causing decay in fruits and vegetables. Initial infection most often occurs at sites of fruit injury, such as bruises or puncture wounds. The blue mould decay of apples is caused by Penicillium expansum and is associated with contamination by patulin, a worldwide regulated mycotoxin. lack the necessary virulence factors to commonly cause human infection, and only in the setting of extreme immunodeficient states can invasive infection occur. Penicillium spp. P. expansum on apple: Post-harvest infection via injuries caused by stalks protruding from neighbouring fruits. This fungus is a wound parasite, for infection the fruits need to be wounded in advance. And because we all need to breathe, we are likely to inhale these spores if there is a mold contamination in our home. Its discovery, as well as the first recognition of Penicillium’s therapeutic potential, happened in the United Kingdom. Lesions caused by P. solitum were small and thus considered unimportant to industry. In addition, he discovered that there was some factor present in Penicillium mold that, apart from inhibiting bacterial growth, might also be used to combat infectious diseases. This will reduce dampness and humidity, which is the key factor in any mold contamination. are ubiquitous in nature and may be recovered with ease from a variety of sources within the hospital environment. 3) and Pilidiella granati (Fig. Nevertheless, colonization must be distinguished from the possibility of invasive disease. The most common types of mold that cause allergies include Aspergillus, Penicillium, Alternaria and Cladosporium. During infection, P. expansum produces the toxic secondary metabolites patulin and citrinin that can impact virulence and, further, render the fruit inedible. The genus was first identified in scientific literature by Johann Heinrich Friedrich Link in his 1809 work Observationes in ordines plantarum naturale. There are over 300 accepted species of Penicillium. Penicillium expansum was the most aggressive and P. crustosum the second most aggressive on all apple cultivars ('Royal Gala', 'Granny Smith', 'Golden Delicious', 'Topred', and 'Cripps Pink') and two pear cultivars ('Packham's Triumph' and 'Forelle… Chronic maintenance therapy with itraconazole is indicated in patients with AIDS. Thus, it is important to control postharvest diseases to increase the shelf life of apples. Little is known of P. crustosum and P. digitatum on stone fruits, even though they seem to pose a potential threat to industry. is prevalent. could interfere in the fruit ethylene biosynthesis at the biochemical and molecular level. TAXONOMY: Penicillium expansum Link 1809. During infection, P. expansum produces the toxic secondary metabolites patulin and citrinin that can impact virulence and, further, render the fruit inedible. Using an air purifier and/or dehumidifier will also help reduce the relative humidity inside your home. Blue mold decay leads to significant economic losses during storage that also impacts fruit destined for processing by its production of the carcinogenic mycotoxin patulin (Barkai-Golan, 2008). Because very little is known about the environmental niche of P marneffei, there are no recommendations or guidelines for prevention and control of this infection. Control of this devastating pathogen mainly relies on the use of fungicides but the development of resistance has become an important factor in limiting the efficacy and useful lifetime of fungicides. (6). Several studies have shown that epigenetic machinery controls synthesis of secondary metabolites in fungi. The present study investigated the interaction between P. expansum and wounded apple fruit tissues during the early stages of the infection. P. expansum … de Hoog, G. S., J. Guarro, J. Gene, and M. J. Figueras, (2000): International Historic Chemical Landmarks – American Chemical Society, (Retrieved in 2018): Kirk, PM; Cannon, PF; Minter, DW; Stalpers, JA., (2008): Pasanen A-L., Lappalainen S., Pasanen P., (1996): Yousef Al-Doory and Joanne F. Domson, Lea and Febiger, (1984). Except for P marneffei, the Penicillium spp. Unfortunately, there has yet to be a consensus since every species of mold presents a different set of health risks. Penicillium can be found practically anywhere, from air and soil to our homes. Ontario, Canada In the laboratory, P marneffei will grow as a mold with hyphal characteristics similar to the other Penicillium spp. Of the approximately 150 recognized species, some are frequently implicated in the deterioration of food products where they may produce mycotoxins. The results show that the fruit ethylene biosynthesis was differently altered during the P. expansum infection than in response to other biotic (non-host pathogen P. digitatum) or abiotic stresses (wounding). Blue mold disease, caused by Penicillium expansum (Link), is the most economically important postharvest disease of fruit and vegetables in storage. caused by Penicillium spp., among which P. expansum (Link) Thom. Some strains of the blue mold causal fungus, Penicillium expansum, secrete patulin, a mycotoxin with mutagenic, neurotoxic, and gastrointestinal effects (Ramalingam et al., 2019). There is a marked predominance of male cases (~ 90%). Indoors, it usually grows on wallpaper, wallpaper glue, carpet, paint, fabrics, house dust and water-damaged buildings in general. 4), no decay was observed on control fruit and fruit inoculated with P. minioluteum. Colletotrichum gloeosporioides and Penicillium expansum cause postharvest diseases in tropical and deciduous fruit. Person-to-person transmission does not occur. In this study, two species of yeast that can biocontrol apple diseases caused by Penicillium expansum were discovered. Penicillium expansum causes blue mold, the most economically important postharvest disease of pome fruit worldwide. However, there are thousands of species of mold, and not all of them cause allergic reactions. It is therefore better to be safe than sorry, and to discard any food items that show signs of mold growth. In most cases where Penicillium spp. It can also contaminate leather goods and other textiles, and is a strong indicator of indoor moisture issues. Several studies have shown that epigenetic machinery controls synthesis of secondary metabolites in fungi. Because skin involvement occurs in nearly two-thirds of patients, skin lesions are usually present and are most commonly found on the face, upper trunk, and arms. mould caused by Penicillium expansumand other Penicilliumspp. The brlA gene encodes a C2H2-type zinc-finger transcription factor, which is essential for asexual development. Infection is acquired via inhalation, inoculation of the skin, and possibly ingestion. 20 per page; 50 per page; 100 per page; Search Results [1… Mold Busters created an open-source library of microscopy images of various kinds of mold which are used to train machine learning algorithms. Penicillium is a common allergen, triggering allergies such as hypersensitivity pneumonitis and hay fever. 8:1240. doi: 10.3389/fmicb.2017.01240 The postharvest pathogens such as R. nigricans, A. flavas and P. expansum are the causal agents of jujube or orange fruit, therefore, in vitro and in vivo antifungal activities of cinnamon oil to inactivate these fungi were investigated.

Some strains of the blue mold causal fungus, Penicillium expansum, secrete patulin, a mycotoxin with mutagenic, neurotoxic, and gastrointestinal effects (Ramalingam et al., 2019). With over 300 accepted species, the Penicillium genus includes some of the most common fungi in the world. Blue mould caused by Penicillium expansum and other Penicillium spp. According to Raper and Thom (1949), the genus includes 1 36 species, distributed throughout the world. Penicillium expansum causes an economically serious postharvest decay of fruits and is known as “blue mold” in reference to the abundant blue-green spores produced by this species and several other Penicillium species that cause the disease (1, 2). RBQ# 5726-4947-01, Kingston, ON Control of primary postharvest diseases caused by Rhizopus stolonifer, Botrytis cinerea, and Penicillium expansum on a variety of fresh fruit was evaluated with an invert emulsion formulation of Trichoderma harzianum.Diseases evaluated were quantified by the period of protection conferred by the antagonist and the diameter of decay lesions. ADVERTISEMENTS: In this article we will discuss about:- 1. May be cultured from a variety of specimens including blood. Penicillium refers to a group of molds that share the same characteristics and can be found all over the world. Penicillium expansum causes blue rot, the most common and destructive postharvest problem encountered in apples and pears (Figure 1). 514-667-3696 advantage that Penicillium expansum is the compatible pathogen and P. digitatum is the non-host of apples, the present study aimed at deciphering how each Penicillium spp. Penicillium spp. Fungal diseases; Alternaria leaf blight Alternaria dauci: Black root rot Thielaviopsis basicola Chalara elegans [synanamorph] Black rot (black carrot root dieback) Alternaria radicina = Stemphylium radicinum. Penicillium is a genus of mold-forming fungi that grow on stored feed , growing plants, crops and damp indoor spaces. The objective of this study is to find out some effective plant essential oils as an alternative to synthetic fungicides against P. expansum causing fruit rot of grapes . Previously known as Penicillium notatum, Penicillium Chrysogenum is a widely studied species of Penicillium that is most famous for being a source of penicillin and several other antibiotics.P. Penicillium expansum was the most aggressive and P. crustosum the second most aggressive on all apple cultivars ('Royal Gala', 'Granny Smith', 'Golden Delicious', 'Topred', and 'Cripps Pink') and two pear cultivars ('Packham's Triumph' and 'Forelle… In tissue specimens, the mycelial elements are somewhat larger at 15-20 um in width and exhibit branching at ~ 45° angles. These fungi are commonly found in soil, food, cellulose, grains, paint, carpet, wallpaper, interior fiberglass duct insulation and decaying vegetation. Penicillium expansum is one of the main pathogens causing decay in fruits and vegetables. Its significance has increased in recent years because it produces a mycotoxin, patulin, which occurs in Penicillium -rotted fruit and subsequently in fruit juice produced from reject fruit. PgAFP produced by Penicillium chrysogenum can inhibit the growth of several P. expansum strains in vitro, and reduce disease incidence and severity in Royal Gala apples (Delgado et al., 2019). Some Penicillium species are capable of producing microbial volatile organic compounds (MVOCs) and toxins that can be harmful to human health, especially upon long-term exposure. P. expansum … Infection with Penicillium spp. Antagonistic yeasts can inhibit fungal growth. Recently, a cluster of 15 genes (patA-patO) involved in patulin biosynthesis was identified in P. expansum. (8) Often, Penicillium molds are found in decaying vegetation, soil and air. The drug of choice for treatment of P marneffei infection is amphotericin B, although in vitro resistance has been described (Box 5). Microbiol. Kingdom: FungiPhylum: AscomycotaClass: EuascomycetesOrder: EurotialesFamily: TrichomaceaeGenus: Penicillium (9) These toxins make food inedible and dangerous. Quebec, Canada In addition to being the first person to suggest that Penicillium mold is capable of secreting an antibacterial substance, Dr. Fleming was also the first person to develop a concentrate of the active substance, penicillin, in 1928. Blue mold decay leads to significant economic losses during storage that also impacts fruit destined for processing by its production of the carcinogenic mycotoxin patulin (Barkai-Golan, 2008). Blue mold decay caused by Penicillium expansum is one of the recently identified diseases of grapes (Vitis vinifera). How each person reacts to the inhalation of Penicillium mold spores is unique. is one of the most common global and economically important post - harvest fruit rot diseases (Zhong et al., 2018). These molds commonly contaminate clinical specimens and cause contamination in the laboratory. Other people involved in the mass production of penicillin included Ernst Chain, Edward Abraham, Howard Florey and Norman Heatle. Cinnamaldehyde is the main constituent of cinnamon oil. Although infections may start in the field, infected spots often become evident post-harvest, and expand while fruit is in storage. Penicillium expansum is one of the most harmful post-harvest pathogens of pomaceous fruits and the causal agent of blue rot disease. No matter what, always try to give your home plenty of fresh air and sunlight. Fungal diseases occur regularly during storage and can cause severe yield and economic losses. P marneffei infection in immunosuppressed patients can be granulomatous or necrotizing and is likely to disseminate. Infected areas are clearly delineated and light brown, and soft decaying tissue can be easily "scooped" out of the surrounding healthy tissue., Spore masses later … When we inhale mold spores into our lungs, we become vulnerable to respiratory problems such as coughing, shortness of breath, chronic sinusitis, sneezing and a runny nose. (7). Infections caused by Penicillium spp. In recent years, researchers have discovered that some yeasts have antagonism against Penicillium expansum. 819-303-0250 In recent years, researchers have discovered that some yeasts have antagonism against Penicillium expansum. Penicillium Chrysogenum. RBQ# 5726-4947-01, Gatineau, QC other than P marneffei occur worldwide. Penicillium. Penicillium are cosmopolitan, predominant in regions of temperate climate. Since Penicillium molds can cause food spoilage, they also present a health hazard when consumed. Infection with P marneffei occurs only in people who have lived or traveled in the endemic areas of Southeast Asia and southern China. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1360277/, https://www.ncbi.nlm.nih.gov/pubmed/17127632, https://en.wikipedia.org/wiki/Penicillium_marneffei. If you do have an allergy to Penicillium, your immune system’s response will be to trigger symptoms like itchy and watery eyes, sneezing, nasal congestion, itchy lips, mouth and nose, or a runny nose. are recovered from clinical specimens, they represent colonization. The increasing concern about the use of chemical substances and pesticides in … They grow rapidly and release a strong musty odour. Aw 0.78 - 0.88 (5) A wide number of organisms have placed in this genera. They are papular in appearance and resemble molluscum contagiosum. In our previous research, Meyerozyma guilliermondii , one of the antagonistic yeasts, exhibited antagonistic activity against Penicillium expansum . Some individuals may experience asthma symptoms or allergic reactions, while others may not feel anything. The most common species of Penicillium include P. chrysogenum (also known as P. notatum), P. purpurogenum, P. janthinellum and P. marneffei (also called Talaromyces marneffei). is prevalent. Blue mold (primarily Penicillium expansum) is a very common post-harvest fungal disease on apples worldwide.This disease is of economic concern to both the fresh-fruit industry and the fruit-processing industry because some strains produce the mycotoxin patulin, which can rise to unacceptable levels affecting the quality of apple juice. Full-strength and 50% EO water decreased viable spore populations by greater than 4 and 2 log units, respectively. Reproduction. Since mold spores are often airborne, your home should be well ventilated with plenty of air exchange. Penicillium rot or blue mould is one of the most common and easily recognised post-harvest rots of apple, but is not necessarily responsible for large losses. is rare; occurs in immunosuppressed patients. Hepatosplenomegaly may be detected on abdominal examination and is more common in children. During colonization, C. gloeosporioides and P. expansum secrete ammonia in hosts with low sugar content (LowSC) and gluconic acid in hosts with high sugar content (HighSC), respectively, as a mechanism to modulate enhanced pathogenicity. Penicillium expansum Es una enfermedad común en manzanas y peras. Postharvest apples are stored in order to provide market with quality of fruits. Front. In tissue specimens, it grows as a small yeast cell that resembles Histoplasma capsulatum. Penicillium rot or blue mould is one of the most common and easily recognised post-harvest rots of apple, but is not necessarily responsible for large losses. It can also trigger or worsen asthma symtpoms. The diagnosis of invasive disease by Penicillium spp. blast analysis revealed that patL encodes a Cys6 zinc finger regulatory factor. These blue-green molds grow rapidly in the mycology laboratory and produce fine septate hyphae with 1.5-5 um wide elements. P. expansum telah ditetapkan sebagai penyebab utama kerusakan buah pome selama beberapa abad yang lalu. Penicillium glaucum Link) Penicillium funiculosum Thom Penicillium oxalicum Currie & Thom Penicillium verrucosum Dierckx Penicillium viridicatum Westling Rhizoctonia ear rot Waitea circinata Warcup & Talbot While disease symptoms were observed after seven days incubation at 20ºC on pomegranates inoculated with P. expansum, P. sclerotiorum, P. glabrum (Fig. (4). One of the Penicillium spp., P marneffei, is unique because of its dimorphic characteristic. Department of Microbiology, Medicine and Pathology, School of Medicine & Health. When cleaning mold, you should avoid exposing yourself to mold spores and mycotoxins. P. expansum is one of the most aggressive and commonly reported Penicillium spp. However, if there are drastically more Pencillium spores indoors than there are outdoors, you definitely have a mold or air quality problem that needs to be addressed. In this study, two species of yeast that can biocontrol apple diseases caused by Penicillium expansum were discovered. Unique among the Penicillium spp., P marneffei is an endemic mycosis that is found in Southeast Asia and southern China. P marneffei found in Southeast Asia and southern China. caused by Penicillium spp., among which P. expansum (Link) Thom. Penicillium expansum causes blue mold disease and is the main source of patulin, a mycotoxin that contaminates apple-based food. Since Penicillium molds are fungi, their tiny spores can become airborne easily and linger in the air without us knowing it. Key word: Penicillium expansum, Blue mold, Apple and Carbendazim fungicide. Isolated case reports of invasive penicilliosis, including prosthetic valve endocarditis, peritonitis, endophthalmitis, and infections at other sites, have been reported in the literature. At Mold Busters, our diagnostic mold inspections and visual assessments often reveal hidden moisture problems that contribute to ongoing mold contamination and decreased indoor air quality inside of homes. In immunocompetent patients, P marneffei infection may resemble histoplasmosis with a granulomatous reaction involving the reticuloendothelial system.
