Stool culture is a laboratory test used to determine the aetiology of infective, bacterial diarrhoea. Stool culture test may sometimes give a false negative result indicating the absence of a pathogenic organism in the sample. Additional charges are incurred for identification and susceptibility testing. Use of a selective enrichment broth to recover Clostridium difficile from stool swabs stored under different conditions. If germs that can cause infection grow, the culture is positive.Culture; isolation and identification (at an additional charge) of Salmonella, Shigella, and Campylobacter, and detection of enterohemorrhagic E coli (EHEC) Shiga toxin by EIA. Bacteria are a common cause of gastroenteritis including diarrhea, ulcer, vomiting, food poisoning, etc. It has a mortality rate of 19%, and when untreated it raises to 60%. ), Tetracycline (suppressed on CSF and blood), Trimethoprim-sulfamethoxazole (suppressed on blood), Gentamicin, high level (suppressed on urine).
