Toxigenic Aspergilli isolated from different sources in Egypt.
45 cultures of Aspergillus, belonging to 25 species isolated from different sources in Egypt, were tested for toxicity to chicken embryos and to Bacillus megaterium growth. Mycotoxins were detected by TLC analysis. 30 isolates out of 45 exhibited toxicity. 3 isolates were recorded as high-toxin producers. (A. egyptiacus, A. carneus and A. terricola). The 2 former produced unknown toxins, while A. terricola produced aflatoxins (B1, B2, G1 and G2). Aflatoxins production by A. terricola is reported for the first time.
