Morphological and Characteristic Diagnosis of Fusarium foetens and the possibility of production mycotoxins

Abstract

The results  of isolation and diagnosis showed that there  were three species of fungi , Aspergillus flavus , Aspergillus parasiticus and Fusarium foetens.                                                   Both Aspergillus flavus , Aspergillus parasiticus  had ability to produce aflatoxins . In contract   F.foetens fungus was able to produce  three toxic metabolic compounds , these compounds affected the physiological blood parameters of albino rat males e.g. a decrease of hemoglobin amount from  11 mg /L ( in untreated ) to 10 .8 mg /L in blood of animals that treated with toxic  compound ( Ffo ₁ ) also raised  the number of white blood cells ( WBC_S )  to 13166 cell /mm³  . Metabolic products also affected the biochemical  parameters by  raising the level of Glutamic Pyruvate Transaminase (GPT ) and Glutamic Oxaloacite  Transaminase (GOT ) to (8 ,7  IU/L ) and (9.9-24.9 ,8-28 IU/ L) respectively .In contrast, cholesterol level was reduced in blood of treated animals with (Ffo₁) the control group   to( 84.58 mg/dl) and ( 67.33- 84.58  mg / dl) respectively.Histological  study showed that all three metabolic compounds caused pathogenic changes in the intestines, as shirnking of its intra structure , vascular congestion and focal aggregate inflammatory cells, while the effects in kidney appeared as hemorrhage around the glomeruli and focal aggregate inflammatory cells .
