Aflatoxin contaminates foods including peanuts. Aflatoxin is a carcinogenic toxin mainly produced bty Aspergillus flavus. Other Aspergillus species that rarely produce aflatoxins are A. nomius and A. niger. Aflatoxin is associated with liver failure, hepatocellular carcinoma (HCC) and death. Recent studies have shown that peanuts in Kenya are highly contaminated with aflatoxins but information ...

BACKGROUND Fungi, especially Aspergillus flavus, can cause chronic rhinosinusitis with nasal polyposis and modulate host innate immune components. The objective of this study was to examine the serum levels of T helper (Th) cell subset Th1, Th2, and Th17 cytokines and total IgE in patients having chronic rhinosinusitis with nasal polyposis and Aspergillus flavus infection. METHODS A case-cont...

Aspergillus infections have grown in importance in the last years. However, most of the studies have focused on Aspergillus fumigatus, the most prevalent species in the genus. In certain locales and hospitals, Aspergillus flavus is more common in air than A. fumigatus, for unclear reasons. After A. fumigatus, A. flavus is the second leading cause of invasive aspergillosis and it is the most com...

Aspergillus flavus is one of the most common contaminants that produces aflatoxins in foodstuffs. It is also a human allergen and a pathogen of animals and plants. Aspergillus flavus is included in the Aspergillus section Flavi that comprises 11 closely related species producing different profiles of secondary metabolites. A six-step strategy has been developed that allows identification of nin...

Fungi are known to produce a vast array of secondary metabolites that are gaining importance for their biotechnological applications. In the present study, the crude methanolic extracts of Aspergillus niger and Aspergillus flavus var. columinaris were tested by the disc diffusion method and minimal inhibitory concentration (MIC) determination for detection of antimicrobial activity against ten ...

silymarin, the principal constituent of silybum marianum, is one of the most commonlyused herbal therapies as a natural antioxidant, hepatoprotector and antihepatotoxic agent,in counteracting the toxic effects of mycotoxins. to determine the efficacy of silymarin,the levels of hematological and serum biochemical parameters of 70 ross broilers from35 to 49 days of age in an experimental chronic ...

Aspergillus flavus and Aspergillus oryzae belong to Aspergillus section Flavi. They are closely related and are of significant economic importance. The former species has the ability to produce harmful aflatoxins while the latter is widely used in food fermentation and industrial enzyme production. This review summarizes the current understanding of the similarity of the A. flavus and A. oryzae...

Most of the information available about Aspergillus infections has originated from the study of A. fumigatus, the most frequent species in the genus. This review aims to compare the pathogenicity and clinical aspects of Aspergillosis caused by A. fumigatus an A. flavus. Experimental data suggests that A. flavus is more virulent than A. fumigatus. However, these were mostly models of disseminate...

Antimicrobial activity of 25, 50, 75 and 100% alcohol extract of Piper nigrum (Black Pepper), Psidium guajava (Guava), Amomum cardamom (Cardamom) and Cynogen dactylon (Bermuda grass) has been evaluated against Pseudomonas lundensis, Bacillus cereus, Aspergillus niger and Aspergillus flavus. Psidium guajava extract showed excellent antimicrobial activity against all the test organisms. In 25% co...

Nine isolates of Aspergillus flavus and Aspergillus parasiticus were screened for aflatoxin production on a coconut extract agar medium. Aflatoxin-producing colonies were detected under long-wave UV light (365 nm) by blue fluorescence on the reverse side after 2 to 5 days of growth. Aflatoxin production was verified by chemical analysis. Several types of shredded coconut available in the United...
