title: Seroprevalence of anaplasmosis in the Red River Plains and south-east areas of Louisiana.
abstract: The indirect fluorescent antibody test was used to detect antibodies to Anaplasma marginale in serum samples collected from cattle in the Red River Plains and South-east areas of Louisiana. Convenience sampling of herd clusters was used. A reactor rate of 7.8% was found in 11,085 samples. Beef cattle had a 11.2% reactor rate compared with 3.8% for dairy cattle. The Angus and Angus cross-breed group had the highest reactor rate.
