Trypanosoma evansi infection in bovine and buffalo calves in Indonesia.
Fifteen bovine and 11 buffalo calves born on different farms in a Trypanosoma evansi-endemic area of West Java were monitored for the presence of T. evansi and T. evansi antibody at monthly intervals until they were 12 months of age. Fifty percent of the bovine and 83% of the buffalo calves sampled in the first month of life were antibody positive. This antibody was considered to be of colostral origin. Antibody developing later in life persisted for up to 12 months and was considered to have arisen in response to T. evansi infection. No protective function could be ascribed to the colostral antibody.
