Prevalence and Burden of Gastrointestinal Parasites in Stray Cattle of Kathmandu Valley
Abstract Gastrointestinal parasites (GIPs) are ubiquitous among cattle resulting severe infection. Prevalence of GIPs in stray street cattle may pose risk of dissemination of parasites of zoonotic importance. This study was conducted to determine the prevalence of GIPs in stray cattle of Kathmandu valley. Hundred (n=100) freshly voided dung samples were collected from eight places. The samples were processed using concentration method for microscopic examination, and modified McMaster technique for quantification of mean eggs/oocysts per gram of feces (EPG/OPG). Results revealed that 72% of the cattle were found positive for one or more species of GIPs and nine genera of GIPs were recorded (Eimeria, Ostertagia, Haemonchus, Trichostrongylus, Capillaria, Trichuris, Toxocara, Fasciola and Paramphistomum). The prevalence of parasitic infection was higher in male (73.68%) than in female (69.76%). The prevalence was found to be highest in adults (63.89%) followed by heifers (27.78%) and calves (8.33%). Approximately 76% of the cross breed and 65% local breed of cattle were positive for parasitic infection. The parasites differed both in prevalence and intensity, Eimeria sp. being the most prevalent (27%) with highest intensity (858.02 OPG ±63.46 SD). To our information, this is the first research of its kind in relation to stray cattle in Nepal. Our findings reveal that there is burden of helminth infections of zoonotic and socioeconomic importance in the straycattle. Therefore, it warrants regular inspection, relevant preventive measures and molecular detection of parasites.
