In simple words: Gastrointestinal tularemia is a bacterial infection of the stomach and intestines. It's caused by bacteria called Francisella tularensis, which can be spread by ticks, insects, or contact with infected animals. Symptoms can include fever, stomach pain, nausea, vomiting, sweating, and swollen lymph nodes.Doctors can diagnose it with blood tests and other lab tests.It's treated with antibiotics.

Gastrointestinal (GI) tularemia is a bacterial infection of the GI tract caused by Francisella tularensis.It can spread from infected rodents and other wild and domestic animals through infected tick or flying insect bites, by direct entry of the bacteria through cuts or sores or touching the mouth with unwashed hands after handling infected dead animals, or from the bacteria entering the blood stream from other infected sites. Symptoms include fever, stomach pain, nausea, vomiting, sweating, and enlarged lymph nodes in the abdominal and inguinal areas. Diagnosis is based on history, symptoms, physical exam, and lab tests including blood cultures, serologic tests, PCR, and microscopic analysis of biopsies. Treatment includes antibiotics such as doxycycline, ciprofloxacin, streptomycin, and tetracycline.

Example 1: A hunter develops fever, abdominal pain, and diarrhea after handling a wild rabbit carcass.Testing confirms Francisella tularensis infection, leading to a diagnosis of gastrointestinal tularemia., A child experiences vomiting and swollen lymph nodes after being bitten by a tick.Blood tests reveal antibodies to Francisella tularensis, and the patient is diagnosed with gastrointestinal tularemia., A farmer develops fever and stomach cramps after drinking contaminated water.A stool culture confirms the presence of Francisella tularensis, resulting in a diagnosis of gastrointestinal tularemia.

Documentation should include signs and symptoms, exposure history (e.g., tick/insect bites, animal contact, contaminated food/water), lab results (e.g., blood cultures, serology, PCR), and response to treatment.
