Abstract
The prevalence of anaplasmosis in Oklahoma cattle was determined on the basis of the standardized Anaplasma marginale complement fixation test on 20,155 sera submitted to the Oklahoma Animal Disease Diagnostic Laboratory during a 15-year period. Rates of seropositivity ranged from 4.7% to 17.6% on samples submitted for anaplasmosis testing of adult cows. The geographic distribution of recorded cases of anaplasmosis was 35 Oklahoma counties in 1977 and 48 Oklahoma counties in 1991.Keywords
