Resumo: | Bovine leukosis virus (BLV) antibodies were screened by Ouchterlony's agar gel immunodiffusion (AGID) test (antigen gp-51) in dairy cattle (Holstein) and beef cattle (Zebu/Nelore) breed, raised in Londrina State, of Paraná/Brasil. The prevalence of antibodies anti-BLV was of 7,0% (69/985) and infected animals were found in 35,7% (5/14) of the farms. In all dairy cattle surveyed, the prevalence rate was of 18,4% (69/374), however, BLV antibodies were not detected in any beef cattle. The more intensive the management, the higher the prevalence rate of BLV was in the herds of dairy cattle (27,4% intensive; 8,5% semi-extensive management). There was a tendency to increase the prevalence rate of BLV reaching its highest rate of BLV as older the dairy cattle were reaching the highest prevalence rate in cows older than 60 months. The values obtained were the following: up to 6 months-8,7% (6/69); 6 to 12 months - 8,3% (5/60); 12 to 24 months -18,6% (13/70); 24 to 60 months - 16,1% (15/ 93) and older than 60 months - 36,6% (30/82). |

The prevalence of antibodies anti-BLV was of 7,0% (69/985) and infected animals were found in 35,7% (5/14) of the farms. In all dairy cattle surveyed, the prevalence rate was of 18,4% (69/374), however, BLV antibodies were not detected in any beef cattle. The more intensive the management, the higher the prevalence rate of BLV was in the herds of dairy cattle (27,4% intensive; 8,5% semi-extensive management). There was a tendency to increase the prevalence rate of BLV reaching its highest rate of BLV as older the dairy cattle were reaching the highest prevalence rate in cows older than 60 months. The values obtained were the following: up to 6 months-8,7% (6/69); 6 to 12 months - 8,3% (5/60); 12 to 24 months -18,6% (13/70); 24 to 60 months - 16,1% (15/ 93) and older than 60 months - 36,6% (30/82). Determinou-se a prevalência de anticorpos séricos anti-Vírus da Leucose dos Bovinos em animais leiteiros da raça Holandesa Preto e Branca e em zebuínos de corte da raça Nelore criados no Polo Regional de Londrina, Estado do Paraná, através da prova de imunodifusão radial dupla de Ouchterlony, em gel de ágar, com uso do antígeno glicoproteíco (gp-51) da cápsula do vírus. A prevalência de anticorpos séricos anti-VLB foi igual a 70% (69/985), sendo que 35,7% (5? 14) das propriedades avaliadas apresentaram animais infectados pelo Vírus da Leucose dos Bovinos. Considerando-se somente os bovinos da raça Holandesa Preto e Branca a a prevalência de anticorpos anti-VLB foi de 18,4% (69/374), enquanto nos rebanhos zebuínos da raça Nelore não se encontrou animais sororeagentes aos antígenos do VLB. A prevalência de anticorpos anti-VLB foi significamente maior nos rebanhos produtores de Leite B (27,4%), do que naqueles criados em propriedades que exploravam a produção de leite C (8,5%). A estratificação da população de bovinos da raça Holandesa Preta e Branca em faixas etárias demonstrou ser a prevalência encontrada nos animais com mais de 60 meses de idade significativamente maior do que as obtidas nos animais mais jovens. Os resultados encontrados nos vários grupos etários estudados foram os seguintes: até 6 meses de idade - 8,7% (6/69); idade entre 6 e 12 meses - 8,3% (5/60); entre 12 e 24 meses de idade - 18,6% (13/70); idade entre 24 e 60 meses - 16,1% (15/93) e nos bovinos com mais de 60 meses de idade - 36,6% (30/82).
