1A0Z/A04.9 Bacterial intestinal infections, unspecified



Bacterial intestinal infections, unspecified, can be caused by a number of bacterial species, including Escherichia coli, Salmonella, Campylobacter, Shigella, Clostridium and Yersinia. These bacteria can be transmitted through contaminated food and water, contact with infected individuals or animals, and improper hygiene.


Diagnosis of bacterial intestinal infection typically involves a combination of laboratory testing, physical examination, and patient history. Tests may include stool sample analysis to detect bacterial presence, blood tests to check for bacterial toxins, and imaging tests such as X-rays or CT scans.

Differential diagnosis

Differential diagnosis of bacterial intestinal infection includes other causes of abdominal pain and diarrhea such as viral infections, food intolerance, irritable bowel syndrome, and inflammatory bowel disease.


Treatment of bacterial intestinal infection depends on the type of bacteria causing the infection and may include antibiotics, antidiarrheal medications, and probiotics.


The prognosis for bacterial intestinal infection is generally good with appropriate treatment. However, some bacterial infections can cause more severe complications such as dehydration, sepsis, and organ failure.
