摘要
Respiratory viral infections are known for serious economic losses in ruminants. Bovine parain-fluenza 3 virus (bPI-3V) a member of Respirovirus genus in association with other respiratory viruses causes respiratory disease complex in ruminants. The aim of this study was to estimate the seroprevalence of bPI-3V in non vaccinated cattle, sheep and goats from Grenada. Sera were collected randomly from 60 sheep, 60 goats and 60 cattle from all six parishes of Grenada. Sera were tested for antibodies to bPI-3V using an indirect Enzyme Linked Immunosorbant Assay (ELISA) kit. Antibodies to bPI-3V were detected in 13.4% (Confidence Level (CL): 95%;Confidence Interval (CI): 4.76% to 22.02%) in cattle;16.7% (CL: 95%;CI: 7.26% to 26.14%) in sheep and 11.7% (CL: 95%;CI: 3.57% to 19.83%) in goats. There was statistically no significant difference in prevalence (p > 0.05) of antibodies to bPI-3V in cattle, sheep and goats in Grenada. This is the first report on seroprevalence of bPI-3V in ruminants in Grenada, West Indies.
