Francisella tularensis is a gram-negative bacterium responsible for tularemia.
Tularemia can be transmitted through insect bites, direct contact with infected animals, ingestion of contaminated water or food, and inhalation of aerosols.
Symptoms can vary based on infection route but commonly include fever, ulceration at the site of infection, and swollen lymph nodes.
The disease is often diagnosed via serological tests or PCR to detect F. tularensis DNA.
Streptomycin is the preferred antibiotic treatment for tularemia, although gentamicin and doxycycline are also effective.
