Prevalence of Bovine Anaplasmosis in Malaysian Farms

The mam objective of this cross sectional study was to determine the prevalence of bovine anaplasmosis in Malaysian farms involving Selangor and Pahang and to determine the potential risk factors related to the seroprevalence. A total of 180 animals from seven dairy farms and 12 beef farms were invo...
