Abstract
This study focuses on the occurrence, identification, and molecular characterization of Eimeria species causing coccidiosis in cattle in the Kashmir Valley, India. Coccidiosis, caused by apicomplexan parasites of the genus Eimeria, poses a significant threat to global cattle farming. Conventional techniques for identification, which rely on the morphology of sporulated oocysts, have drawbacks, leading to the adoption of molecular techniques to accurately delimit species. A total of 190 cattle were sampled in nine farms and parasitological examination revealed an occurrence of 45.7% for Eimeria spp. Molecular analysis using PCR and sequencing identified three predominant species: E. zuernii, E. alabamensis, and E. bovis. The study highlights the widespread occurrence of these species globally, as supported by previous research conducted in Bangladesh, Austria, Egypt, and Brazil. The phylogenetic analysis based on internal transcribed spacer (ITS-1) gene sequences revealed distinct clusters for E. zuernii and E. bovis, while E. alabamensis formed a separate clade. The genetic diversity and phylogenetic connections provide insights into the evolutionary relationships among these Eimeria species. This study contributes valuable information for understanding the epidemiology and genetic diversity of cattle coccidiosis in the Kashmir Valley, emphasizing the importance of molecular characterization for accurate species identification.
