Detection of E. coli O157: H7 bacteria in Iraqi soft cheese in some areas of Baghdad

Abstract

in this study 25 samples of Iraqi soft cheese were collected from different areas in Baghdad. The total number of isolates was 82, the number of fermented isolates of sorbitol was 60 and unfermented isolates of sorbitol was 22.

The diagnosis of non-fermented isolates of sorbitol was carried by cultural, Morphological and Biochemical diagnosis, the results of the biochemical tests initially showed that the isolate belongs to the E. coli O157: H7 serotype.

The latex test results indicate a clear appearance of granularity (agglutination) when using drops of O157 Test Latex reagent compared to control treatment
