Characterization of shiga toxin producing escherichia
antibiotic resistance bacteria, Shiga Toxin-Producing
Escherichia coli, food products.
Shiga toxin-producing Escherichia coli (STEC) represent a severe public health issue worldwide, causing life-threatening diseases in the human gastrointestinal tract. This study aimed to determine the occurrence of virulent and antibiotic-resistant STEC in retail meat, milk products and human stool samples and to characterize the genes encoding for virulence and antibiotic resistance among the identified STEC isolates. Therefore, a total of 260 food samples (minced meat, beef luncheon, oriental sausage, beef burger and Karish cheese) were collected from retail markets in different localities at El Giza Governorate, Egypt. Additionally, 50 stool specimens were taken from children that had diarrhea at Imbaba Fever Hospital. Bacteriological examination showed a relatively high occurrence of E.coli in meat products (25%), in karish cheese (20%) and in human (28%) specimens. Serotyping of the food product isolates revealed the predominance of non-O157 (82.3 %) with the
