SEROPREVALENCIA DEL VIRUS DE LA RINOTRAQUEITIS INFECCIOSA BOVINA EN GANADO LECHERO DEL VALLE DE LIMA
The seroprevalence of bovine herpes virus type 1 (BHV-1), the causative agent of Infectious Bovine Rhinotracheitis (IBR) was determined in non-vaccinated bovines older than 6 months of age and reared in 12 dairy farms in the valley of Lima, Peru. Blood samples were collected from 395 animals and assayed for antibodies to BHV-1 by using virus neutralization test. Antibodies against BHV-1 were detected in 26 ± 0.47% (143/395) of the animals with titers between 2 and >256. Sixty seven per cent (8/12) of herds had seropositive animals. The higher prevalence was found in herds with more than 300 animals and in herds located in the north and south of Lima, and in those animals older than 2 years. These results confirmed the wide distribution of BHV-1 in the Lima valley, despite of the absence of clinical signs. Since farmers have indicated to have observed respiratory diseases in young animals, the BHV-1 would be associated to the bovine respiratory complex in calves.

El presente estudio tuvo como objetivo determinar la seroprevalencia del virus herpes bovino tipo 1 (VHB-1), agente causal de la Rinotraqueitis Infecciosa Bovina (RIB), en bovinos mayores de 6 meses de edad, procedentes de 12 hatos lecheros del valle de Lima y sin historia de vacunación. Se tomó muestras de sangre en 395 hembras para la detección de anticuerpos neutralizantes en suero mediante la prueba de neutralización viral. El 36 ± 0.47% (143/395) de los animales presentaron anticuerpos neutralizantes contra el VHB-1 con títulos entre 2 a >256. El 67% (8/12) de los hatos muestreados tuvieron animales seroreactores. Las mayores prevalencias se presentaron en hatos con >300 animales, en hatos ubicados en el norte y sur del valle de Lima y en animales mayores de 2 años de edad. Estos resultados confirman que el VHB-1 está difundido en el valle de Lima a pesar que no se obtuvo evidencias clínicas de la RIB. Sin embargo, considerando que los ganaderos manifestaron observar problemas respiratorios en animales jóvenes, esto podría ser indicativo que el virus estaría asociado al complejo respiratorio bovino.
