Epidemiological insights into bovine helminthiasis in Upper Egypt: Prevalence, risk factors, and pathological findings

Year: 2025

Type: article

Abstract: This study examines the prevalence ofhelminthic infestations, risk factors, and odds ratios in1300 cattle, revealing significant patterns inparasite distribution and influencing factors. Overall, 60.3% ofcattle were infested with one ormore types ofparasites, with Moniezia spp. being the most prevalent (46.9%), followed byFasciola spp. (36.9%), Paramphistomum spp. (26.8%), and Avitellina spp. (10.8%). Among the seasons, winter exhibited the highest infestation rate (66.1%), and calves under one year ofage were more commonly infested (64.2%) than older cattle (over three years: 51.1%, OR=0.5841). Distinct seasonal and age-related patterns were observed for specific parasites. Fasciola spp. was most prevalent inwinter (45.09%) and among the youngest cattle (47.87%), while Paramphistomum spp. and Moniezia spp. showed less variation across seasons. Avitellina spp. had the lowest infestation rates inthe spring, and cattle older than three years were affected. Co-infections were common, notably between Fasciola and other parasites, with the highest co-infestation rate observed between Avitellina spp. and Moniezia spp. Analysis ofdeworming efficacy indicated higher treatment success for Fasciola spp. and Paramphistomum spp., lower odds ofresponse for Avitellina spp., and nosignificant treatment effect for Moniezia spp. Microscopic and pathological examinations were also conducted. These results demonstrate the necessity of thorough deworming procedures along with targeted parasite control to reduce significant health hazards in cattle populations.
