Ulceroglandular tularemia: a typical case of relapse.

: Tularemia is an infectious disease that continues to occur sporadically and in epidemics in the United States. It is characterized as an acute febrile illness with constitutional symptoms associated with skin, glandular, respiratory, or gastrointestinal involvement. Tularemia usually can be treated effectively with streptomycin. Relapse most often occurs when patients are treated with bacteriostatic agents such as chloramphenicol or tetracycline. We present a case of ulceroglandular tularemia distinguished by its relapse after initial streptomycin/doxycycline therapy and subsequent slow response to additional streptomycin.
