Toxigenic Aspergilli isolated from different sources in Egypt. 1977

A H Moubasher, and I A el-Kady, and A Shoriet

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.

UI	MeSH Term	Description	Entries
D002642	Chick Embryo	The developmental entity of a fertilized chicken egg (ZYGOTE). The developmental process begins about 24 h before the egg is laid at the BLASTODISC, a small whitish spot on the surface of the EGG YOLK. After 21 days of incubation, the embryo is fully developed before hatching.	Embryo, Chick,Chick Embryos,Embryos, Chick

D001681	Biological Assay	A method of measuring the effects of a biologically active substance using an intermediate in vivo or in vitro tissue or cell model under controlled conditions. It includes virulence studies in animal fetuses in utero, mouse convulsion bioassay of insulin, quantitation of tumor-initiator systems in mouse skin, calculation of potentiating effects of a hormonal factor in an isolated strip of contracting stomach muscle, etc.	Bioassay,Assay, Biological,Assays, Biological,Biologic Assay,Biologic Assays,Assay, Biologic,Assays, Biologic,Bioassays,Biological Assays
D013045	Species Specificity	The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
