ZACARIAS R, Erik; BENITO Z, Alfredo  e  RIVERA G, Hermelinda. Seroprevalencia del virus de la rinotraqueitis infecciosa en bovinos criollos de Parinacochas,  Ayacucho. Rev. investig. vet. Perú [online]. 2002, vol.13, n.2, pp.61-65. ISSN 1609-9117.

The seroprevalence of Bovine Herpes Virus-1, the etiological agent of Infectious Bovine Rinotracheitis, was evaluated in criollo cattle from the districts of Coracora, Chumpi, Puyusca and Pullo of the Parinacochas Province, Ayacucho. A total of 469 serum samples from 25 herds were tested by virus neutralisation test to detect neutralizing antibodies. The 67.6 + 4.2% (317/469) of the samples had antibodies against BHV-1. The seroprevalence of the virus was similar in the animals of the 4 districts under evaluation. The antibody titers ranged from 2 to 256. All sampled herds had seroreactive animals. The study reported the presence of the BHV-1 in criollo cattle of the Parinacochas province, with a higher prevalence than the described in dairy herds in the country.
