BETANCOURT, A et al. ENTEROPATHOGENICITY OF A BOVINE CORONAVIRUS STRAIN. Rev Salud Anim. [online]. 2009, vol.31, n.1, pp.18-23. ISSN 0253-570X.

The experimental reproduction of diarrheas was achieved in newborn calves deprived from calostrum, after inoculation by oral route of a Bovine coronavirus strain, Guayabal. Diarrheas appeared at 24 hours post-inoculation. In all inoculated calves, anatomo and histopathological lesions which corresponded to the disease were observed in necropsy. Bovine coronavirus was excreted after the establishment of diarrhea and not any other pathogenic microorganism involved was found. This sustained the enteropathogenicity of the Guayabal strain.

Keywords : bovine coronavirus; strain; enteropathogenicity.
