[Foot-and-mouth disease in buffaloes (Bubalus bubalis, Linnaeus, 1758): search of antiantigen antibodies and isolation of the virus].

The immune response to virus-infection-associated (VIA) antigen was studied in 379 Indian buffalos (Bubalus bubalis). These animals were vaccinated three times a year with commercial acetylethyleneimine (AEI)--inactivated foot-and-mouth disease vaccines under field conditions. Two months after the last vaccination, antibody against virus-infection-associated (VIA) antigen was found in 23 per cent. Foot-and-mouth disease virus -- (FMDV) type C "Waldmann" was isolated from oesophageal/pharyngeal fluid of 7 samples buffalos.
