MAIDANA, S.S. et al. Herpesvirus bovino 1 (BoHV-1): actualización de las cepas circulantes en Argentina. Rev. vet. [online]. 2018, vol.29, n.1, pp.52-56. ISSN 1669-6840.  http://dx.doi.org/10.30972/vet.2912791.

BoHV-1 in cattle results in a wide range of clinical manifestations, such as infectious bovine rhinotracheitis, abortion and infectious pustular vulvovaginitis, depending on the virulence of the virus and the immune status of the host. Forty-four Argentinean BoHV1 isolates were characterized by restriction endonuclease analysis (REA). Viral DNA was cleaved with HindIII which allows the differentiation among subtypes 1.1, 1.2a and 1.2b. According to the REA, 35 field strains (80%) showed a pattern similar to K22 strain (BoHV-1.2b prototype), 7 field strains (16%) showed a clear pattern similar to LA strain (BoHV-1.1 prototype) and only 2 filed strains (4%) showed a clear pattern similar to ST strain (BoHV-1.2a prototype). The results demonstrated the presence of a marked prevalence of subtype 1.2b among Argentinean BoHV-1 isolates. We also report for the first time in Argentina the circulation of the subtype BoHV-1.2a
