Francisella Tularensis

Francisella tularensis is a highly infectious Gram-negative bacterium in the genus Francisella, which is one of the most dangerous zoonotic pathogens known to cause the infectious disease known as tularemia. It is typically contracted through the bite of an infected animal or contact with contaminated water, soil, or food. Human-to-human transmission is rare, but can occur through respiratory droplets or direct contact. Symptoms of tularemia can range from mild to severe and can include fever, skin ulcers, painful lymph nodes, and respiratory problems. With early detection and treatment, the infection is often treatable with antibiotics, but can be fatal in severe cases. As the causative agent of an infectious disease, Francisella tularensis is of public health significance.
