Biologic and immunologic characterization of rabies virus isolates of domestic animals from rabies endemic areas of Brazil
Keywords:Zoonoses, Rabies, Rabies virus, Antigens (immunofluorescence)
Biologic and immunologic profiles of rabies virus isolates obtained from domestic animals of endemic areas were compared to the CVS rabies virus by means of mice inoculation, serum-neutralization test and by the fluorescent antibody technique (FA). The mean incubation period was 10.2 days, with a range of 4 and 23 days; the disease period was found with a mean period of 3.3 days with a range of 1 and 5 days; the overall value of pathogenicity was 96.5% (332/344) and clinical manifestations all resembled rabies. All rabies virus isolates have reacted specifically to FA test and they all revealed immunologic identity to the standard strain of the CVS virus through the serum-neutralization technique.
