Enzootic bovine leukosis virus in Brazil

Tropical Animal Health and Production, 1981
A 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

Eradication of enzootic bovine leukosis from Finland

Preventive Veterinary Medicine, 2003
Enzootic bovine leukosis (EBL) was recognized among Finnish cattle in 1966. Administrative decisions specifying and refining official control measures were given in 1966, 1976, 1980, and 1993. The measures' key principle always has been 'test and slaughter'.

Studies on the sporadic and enzootic forms of bovine leukosis

Journal of Comparative Pathology, 1979
Abstract The relationship between the skin form of bovine lymphosarcoma (SLS) and bovine leukemia virus (BLV) was studied by a number of immunological techniques. Neither C-type virus expression, BLV antigens in culture cells nor antibody to BLV antigens were found in the SLS case. The percentage of B and T cells in lymphoid cells of the SLS case was

The eradication experience of enzootic bovine leukosis from Lithuania

Preventive Veterinary Medicine, 2007
Before 1985 the situation regarding enzootic bovine leukosis (EBL) in Lithuanian cattle was described only haphazardly. In 1986 serological investigations were initiated together with an eradication programme. The EBL bovine leukosis virus (BLV) situation was monitored by the Institute of Immunology Vilnius University, national and regional veterinary ...

Enzootic bovine leukosis–-a slow virus disease [PDF]

open access: possibleOutlook on Agriculture, 1984
In 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 ...

Study on the Diagnosis of Enzootic Bovine Leukosis by Complement Fixation

Zentralblatt für Veterinärmedizin Reihe B, 1977
SummaryThe presence of antibodies directed against Bovine Leukemia Virus (BLV) antigens was studied by complement‐fixation technique in 245 animals from 5 leukemic herds. Fifty animals reacted positively to the CF test while 45 were immunodiffusion‐positive and 41 had hematological disorders (lymphocytes counts) classified as leukemic or suspicious by ...
