Clinical Utility

Tularemia is primarily a disease of wild animals. The organism, F. tularensis is commonly found in nature. Many wild and domestic mammals, birds, and common house pets have been infected. The disease often begins with the sudden onset of flu-like symptoms (chills, fever, headache and body aches). Incubation is 2-10 days. A positive assay supports the clinical diagnosis of tularemia. Tularemia agglutinins appear in 10-14 days and peak in 5-10 weeks. A four-fold increase during illness or a single titer greater than 1:160 suggests infection. Titers decrease over years.
