Stool Culture is a microbiological test that identifies and isolates bacterial pathogens from stool samples to diagnose gastrointestinal infections. This test is essential for detecting foodborne illnesses and bacterial causes of diarrhea, including Salmonella, Shigella, Campylobacter, and pathogenic E. coli strains. The test involves culturing stool samples on selective media to grow and identify specific bacteria, followed by antimicrobial susceptibility testing to guide appropriate antibiotic treatment. Stool cultures are typically ordered when participants present with symptoms such as bloody diarrhea, fever, severe abdominal pain, or persistent gastrointestinal symptoms. The test is particularly important for participants who have recently traveled to areas with poor sanitation, have been exposed to known bacterial agents, or have symptoms that suggest a bacterial rather than viral cause of their illness.
