Diarrhea, API 20 E, Antibiotics resistance.


This study was conducted to isolate some types of bacteria that cause diarrhea in humans, and 350 stool samples were collected from all ages of both sexes who suffer from diarrhea in Al-Shatrah General Hospital, Bint Al-Huda Hospital, and the Public Health Laboratory in Thi-Qar province. Morphological traits routine and advanced biochemical tests were adopted in this study, The results showed that the percentage of diarrhea-causing bacteria isolates in stool samples was (5.71%), Salmonella (4) (20%), Aeromonas  (2) (10%), Enterobacter  (14) (70%). Enterobacter had the highest rates of resistance to Cefotaxime/clavulanic acid (28.571%), while Aeromonas had the highest rates of sensitivity to the same antibiotic (50%).
