Abstract

Antibodies specific to bovine leukosis (leukemia) virus (BLV) were examined by enzyme-linked immunosorbent, assay (ELISA) in 2,849 serum sample from exotic/improved and indigenous cattle originating from 6 regions of Tanzania, 2,047 from dairy cattle and 802 from beef cattle. An overall infection rate (prevalence) of approximately 36% was detected. The infection rates were 41% and 21.4% in dairy and beef herds respectively. In the dairy herds the infection rate varied from herd to herd. The possible sources of infection and methods of spread within Tanzania are discussed.

摘要

通过酶联免疫吸附测定（ELISA）检测了来自坦桑尼亚6个地区的外来/改良牛和本地牛的2849份血清样本中针对牛白血病病毒（BLV）的特异性抗体，其中2047份来自奶牛，802份来自肉牛。检测到总体感染率（患病率）约为36%。奶牛群和肉牛群的感染率分别为41%和21.4%。在奶牛群中，感染率因牛群而异。文中讨论了坦桑尼亚境内可能的感染源和传播方式。
