Penicillium digitatum (/ ˌ p ɛ n ɪ ˈ s ɪ l i əm ˌ d ɪ dʒ ɪ ˈ t eɪ t əm /) is a mesophilic fungus found in the soil of citrus-producing areas. [1] [2] [3] It is a major source of post-harvest decay in fruits and is responsible for the widespread post-harvest disease in Citrus fruit known as green rot or green mould.
Salmonella Typhi which causes typhoid fever is different from the other Salmonella bacteria that usually cause salmonellosis, a common type of food poisoning. [10] Diagnosis is performed by culturing and identifying S. Typhi from patient samples or detecting an immune response to the pathogen from blood samples.
Penicillium expansum, a pathogen of apples and other fruit, produces patulin; Penicillium glabrum; Penicillium glaucum, a mold that is used in the making of some types of blue cheese, including Bleu de Gex, Rochebaron, and some varieties of Bleu d'Auvergne and Gorgonzola. Penicillium imranianum; Penicillium italicum, a Citrus pathogen ...
Penicillium expansum produces the mycotoxin patulin, a neurotoxin that can enter the food supply via apples and apple products such as juice and cider. [19] Considering the size of the apple product industry and the large number of people that may come into contact with infected fruits, control of P. expansum is vitally important. [20]
Aspergillus penicillioides is a species of fungus in the genus Aspergillus, and is among the most xerophilic fungi. [1]Aspergillus penicillioides is typically found in indoor air, house dust, and on substrates with low water activity, such as dried food, papers affected by foxing, and inorganic objects such as binocular lenses. [2]
These pathogens typically reach the large intestine after entering orally, through ingestion of contaminated food or water, oral contact with contaminated objects or hands, and so on. Each specific pathogen has its own mechanism or pathogenesis, but in general, the result is damage to the intestinal linings, leading to the inflammatory immune ...
The ability of the pathogen to survive within the macrophages probably determines latency of the disease, dissemination and resistance to antifungal agents. In order to survive in the hostile intracellular environment of the macrophage, one of the responses of C. neoformans is to upregulate genes employed in responses to oxidative stress. [11]
Physical methods to prevent growth of mycotoxin‐producing fungi or remove toxins from contaminated food include temperature and humidity control, irradiation and photodynamic treatment. [36] Mycotoxins can also be removed chemically and biologically using antifungal/anti‐mycotoxins agents and antifungal plant metabolites .
