Aspergillus niger is used in the chemical industry for a variety of applications, while also being a known food contaminant and a possible pathogen to humans. Aspergillus oryzae and A. sojae are used in East Asian cuisine in the production of sake , soy sauce and other fermented food products.
Aspergillus fumigatus is a species of fungus in the genus Aspergillus, and is one of the most common Aspergillus species to cause disease in individuals with an immunodeficiency. Aspergillus fumigatus , a saprotroph widespread in nature, is typically found in soil and decaying organic matter, such as compost heaps, where it plays an essential ...
Within the lungs of such individuals, the fungal hyphae spread out as a spherical growth. With the restoration of normal defense mechanisms, neutrophils and lymphocytes are attracted to the edge of the spherical fungal growth where they lyse, releasing tissue-digesting enzymes as a normal function. A sphere of the infected lung is thus cleaved ...
Humans are home to 10 13 to 10 14 bacteria, roughly equivalent to the number of human cells, [2] and while these bacteria can be pathogenic to their host most of them are mutually beneficial to both the host and bacteria. The human immune system consists of two main types of immunity: innate and adaptive.
Cases of tularemia, also known as “rabbit fever," are on the rise in the U.S., according to a new report from the CDC. The report identifies symptoms and the groups most at risk.
In humans, A. terreus is less commonly encountered as a pathogen than other Aspergillus species, most notably A. fumigatus, A. flavus and A. niger. [24] [26] Although less frequently seen in clinical samples, A. terreus displays evidence of amphotericin B resistance which correlates to a high rate of dissemination and an overall poor prognosis ...
