Kc. Schoepf et al., SEROLOGICAL EVIDENCE OF THE OCCURRENCE OF ENZOOTIC BOVINE LEUKOSIS (EBL) VIRUS-INFECTION IN CATTLE IN TANZANIA, Tropical Animal Health and Production, 29(1), 1997, pp. 15-19
Antibodies specific to bovine leukosis (leukemia) virus (BLV) were exa
mined by enzyme-linked immunosorbent assay (ELISA) in 2,849 serum samp
les from exotic/improved and indigenous cattle originating from 6 regi
ons 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 respec
tively. In the daily herds the infection rate varied from herd to herd
. The possible sources of infection and methods of spread within Tanza
nia are discussed.
