Abstract
The present study was undertaken to determine the gastrointestinal parasitism in buffaloes of Jammu region based on fecal examination (n=1680). Most prevalent parasite recorded was amphistome (7.9%) followed by Buxtonella spp. (7.5%), coccidia (5.8%), strongyles (5.6%), ascarids (0.3%) and Moniezia spp. (0.06%). The mixed infections were found in 12.3% of samples examined. Monsoon season showed significantly higher (p<0.01) prevalence (54.3%) in comparison to summer (50.2%), post-monsoon (33.6%) and winter (20.2%) seasons. In males, the infection rate was higher (44.3%) than females (39.2%). The animals aged up to 6 months showed significantly higher (p<0.01) prevalence (54.3%) in comparison to animals above 6 months to 1 year (40.3%) and above 1 year (38.3%) age groups. The irrigated area showed significantly higher (p<0.01) prevalence rate (49.9%) in comparison to rain-fed area (29.3%). Based on the morphological characteristics of sporulated oocysts, nine species of Eimeria were identified as E. bareillyi (28.6%), E. zurenii (18.0%), E. bovis (14.0%), E. subspherica (12.8%), E. canadensis (9.0%), E. alabamensis (6.2%), E. ellipsoidalis (5.4%), E. auburnensis (3.3%) and E. cylindrical (2.7%). Molecular characterization of strongyle larvae revealed Ostertagia and Trichostrongylus targeting ITS-2 gene fragments at 293 bp and 237 bp, respectively.
