Aspergillus flavus Link:Fr. may infect seed of corn, cotton, peanut, and tree nuts and contaminate them with aflatoxins, which are potent hepatoxic, carcinogenic metabolites that pose a significant health hazard (3,4). Members of Aspergillus section Flavi are widespread in crop fields, particularly in subtropical to tropical latitudes (5,11,17,19). Population biologists seek to understand the g...

background and objectives: food contamination by aflatoxins is an important food safety concern for agricultural products. in order to identify and develop novel antifungal agents, several plant extracts and isolated compounds have been evaluated for their bioactivities. anti-infectious activity of piper betle used in traditional medicine of malaysia has been reported previously. materials and ...

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...

Aflatoxin contamination in corn caused by Aspergillus flavus Link is a serious constraint on economical corn (Zea mays L.) production in the Mississippi Delta. The ecology of A. flavus was evaluated in a 3-year study assessing the spatial variability of soil populations of A. flavus in a Mississippi Delta field under different crops. A 1.07-ha section of the field was laid out in 126 9.2-m2 plo...

The aflatoxin producer Aspergillus flavus and the koji mold Aspergillus oryzae are morphologically similar species that belong to the Aspergillus section Flavi. We used amplified fragment length polymorphism (AFLP) to differentiate these two species. In this study, we tested thirteen A. flavus, nine A. oryzae, and three A. flavus var. columnaris strains. DNA fragment profiles amplified with eac...

abstract in order to investigate correlation between the rate (amount) of micro and macro elements and protein percentage in pistachio kernels of six cultivar including: akbari, abbasali, kaleh gouchi, ahmadaghaie, ouhadi and khanjari with aspergillus flavus growth and aflatoxin b1 production, the amount of micro and macro elements were measured using atomic absorption, micro-kjeldhal digestion...

One hundred-thirty soil isolates of A. flavus were collected from commercial pistachio orchards in two main production regions including Rafsanjan (Kerman Province, south-eastern of Iran) and Damghan (Semnan Province, central north of Iran) and assayed for vegetative compatibility groups (VCGs). The sixteen and twenty VCGs were identified for 41 and 37 nit-mutant producing isolates of A. flavus...

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...

In order to evaluate pistachio contamination to Aspergillus flavus in Semnan province; samples of pistachio kernels were collected from the last processing pistachio stage in traditional and semi-mechanized processing plants in 2010. They were examined for the presence A. flavus fungi. The samples were cultured on AFPA media. All plate were incubated for 3 to 7 days. At the end of incubation pe...
