ABSTRACT
Gastrointestinal parasites (GIPs) are common 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 the Kathmandu valley. One hundred (n = 100) freshly voided dung samples were collected from eight sites. The samples were processed using the 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 males (73.68%) than in females (69.76%). The prevalence was found to be highest in adults (63.89%) followed by heifers or steers (27.78%) and calves (8.33%). Approximately, 76% of the cross breed and 65% of the local breed of cattle were positive for parasitic infection. The parasites differed both in prevalence and intensity. Eimeria sp. was the most prevalent (27%) species and had the highest intensity (858.02 OPG ± 63.46 SD). To our knowledge, this is the first research of its kind in relation to stray cattle in Nepal. Our findings reveal that there is a burden of helminth infections of zoonotic and socioeconomic importance in straycattle. Therefore, we recommend regular inspection of stray cattle and relevant preventive measures be put in place.
