Coproculture

Coproculture is a type of laboratory analysis used to detect bacterial infections in the digestive tract. This stool analysis is particularly indicated when a patient exhibits symptoms such as diarrhea, abdominal cramps, with or without fever, suggesting a possible infection.

To determine the presence of a bacterial infection, a stool sample is collected for coproculture. At IntroLab in Vračar, we perform coproculture test to identify potentially present pathogenic bacteria and assess their sensitivity to specific antibiotics. This allows for accurate diagnosis and selection of appropriate treatment.

When is Coproculture indicated?

Coproculture is recommended when symptoms such as diarrhea (including bloody diarrhea), fever, nausea, abdominal pain, and cramps are present. These symptoms, particularly if prolonged, can lead to dehydration, requiring fluid and electrolyte replacement. In some cases, these symptoms can escalate into a serious condition known as hemolytic-uremic syndrome, which poses significant risks for the elderly, young children, and individuals with weakened immune systems.

Microbiological stool examination can identify various bacteria, including Campylobacter species, Salmonella species, and Shigella species. Some bacteria, such as Escherichia coli and Clostridium difficile, cause illness through toxin production. For these bacteria, culturing is performed, but it is also crucial to detect their toxins through additional tests.

Interpretation of results

A negative coproculture result means that no pathogenic bacteria were found in the stool sample. This indicates that there is no need for antibiotic therapy, and the cause of the symptoms is likely due to other factors.

A positive coproculture result indicates the presence of pathogenic bacteria in the stool sample. Following a positive result, additional tests, such as an antibiogram, may be performed to determine the bacteria’s sensitivity to specific antibiotics. This information is crucial for doctors to select the most effective antibiotic therapy to treat the infection.
