Rapid laboratory diagnosis of ulceroglandular tularemia with polymerase chain reaction.

Tularemia is a zoonotic disease which, in Scandinavia, is usually acquired through a mosquito bite. As the infecting organism, Francisella tularensis, is highly virulent the culturing of F. tularensis has generally been avoided. PCR offers a safe way to rapidly confirm diagnosis of tularemia. The case of a 9-y-old boy with ulceroglandular tularemia is presented. The diagnosis was made rapidly with DNA amplification from a pus specimen. The efficacy of ciprofloxacin treatment of tularemia in children is also discussed.
