Abstracts of the papers presented at the 16th Annual Convention and International Symposium of Indian Virological Society on “Management of Vector-Borne Viruses” at International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Patancheru-502324, Hyderabad, India, February 7–10, 2006.
Foot and mouth disease virus (FMDV) is endemic in the Northeastern states particularly in Assam. The disease causes high morbidity and mortality in animals. During the period from 1996–2005, a total of 451 outbreaks were recorded in Assam, out of which 52 (11.52%) out break occurred in vaccinated animal herds and 399 (88.47%) in unvaccinated animal herds. The sample collected from these outbreaks were typed by Sandwich ELISA and the type O, A and Asia-1 of the FMDV could be detected from 280, 106 and 14 outbreaks, respectively. A controlled study carried out to estimate the economic losses showed that the losses incurred in vaccinated animals were les than those from unvaccinated animals. It was also observed that type O virus occurring more in both vaccinated and unvaccinated animals. Severity of the disease and duration of the outbreak was more in unvaccinated herds compared to vaccinated herds.
