Bovine Anaplasmosis is an infectious, hemolytic disease transmitted by the rickettsia parasite Anaplasma marginale in cattle. A. marginale parasitizes the red blood cells of an animal throughout their lifetime. The beef cattle industry is the fifth largest agricultural commodity in Arkansas, so potential economic losses due to bovine anaplasmosis is a critical issue. Previously tested beef cattle herds at the University of Arkansas’ Savoy and Batesville units have tested seropositive for A. marginale with low percent inhibitions; however, all seropositive animals tested negative for infection on DNA analysis. The objective of this study was to determine the current infection status …

Anaplasmosis is an economically devastating disease in cattle that is caused by the rickettsial pathogen Anaplasma marginale. It is estimated that this parasitic bacterium causes over $300 million in expenses for the U.S. cattle industry annually. In Arkansas, the beef cattle industry is the fifth largest agricultural commodity in the state, thus necessitating a better understanding of this disease along with its prevalence. In this study, both polymerase chain reaction (PCR) and competitive enzyme-linked immunosorbent assay (ELISA) tests were used to determine the prevalence of A. marginale infection in Arkansas beef cattle on pasture in the six commonly known geographical …
