Abstract

The objective of this study was to utilize both polymerase chain reaction (PCR) and competitive enzyme-linked immunosorbent assay (cELISA) tests to determine the general prevalence of A. marginale in Arkansas beef cattle within 6 different geographical regions of the state. Anaplasmosis is an economically devastating disease in cattle that is caused by the rickettsial parasite Anaplasma marginale. It is estimated that this parasite causes over $300 million in expenses for the US cattle industry annually. In Arkansas, the beef cattle industry is the fifth largest agricultural commodity in the state. As a result, a better understanding of this disease and its prevalence within the state is needed.
