Enzootic bovine leukosis virus in Brazil
Tropical Animal Health and Production, 1981A sero-epidemiological survey for antibodies to the glycoprotein of enzootic bovine leukosis virus showed that the infection is widely disseminated in the State of Rio de Janeiro, Brazil. Sero from 1,290 females and 154 males from 12 dairy herds were tested by the agar gel precipitin test. Seven hundred and one females (54.3%) and 68 males (44.2%) were

Integration of bovine leukaemia virus at all stages of enzootic bovine leukosis
Archives of Virology, 1991Integration of bovine leukaemia virus DNA was investigated at all stages of infection in cattle. We report here the detection of integrated proviral DNA in the majority of antibody positive animals without lymphocytosis. In all but one case virus was integrated at a number of different sites.

Serological and haematological diagnosis of enzootic bovine leukosis in cattle in Turkey
Veterinary Record, 1995A serological study of enzootic bovine leukosis in the Bursa Region of Turkey showed that of 459 cattle (282 Holstein, 127 Brown-Swiss and 50 native Boz breed) 42 (9.15 per cent) were seropositive. The seropositive cattle had higher IgG1 (P < 0.001) and lower IgM (P < 0.01) levels than the seronegative cattle.

Enzootic bovine leukosis–-a slow virus disease
Outlook on Agriculture, 1984In many countries, enzootic bovine leukosis is of minor economic importance compared with diseases such as brucellosis and Rift Valley fever, and this has tended to limit interest in its cause and prevention. In central and eastern Europe, however–-and in certain herds in the USA and Colombia–-the incidence and fatality rate is high enough to cause ...
