Epidemiological analysis, pathological examination, and influencing factors associated with the Monizia parasite in cattle in New Valley, Upper Egypt.

Abstract

Moniezia infection, caused by cestodes of the genus Moniezia, poses a significant parasitic challenge within bovine populations globally, particularly impacting cattle health and productivity in Egypt. This study aimed to investigate the epidemiology of Moniezia infection in Egyptian cattle, integrating epidemiological data with microscopic and pathological analyses. A cohort of 700 cattle from the New Valley Governorate was assessed over one year, with 260 (37.2%) cases of helminth infections confirmed. Factors such as season, age, and study location significantly influenced infection rates, with the highest rates observed in winter, among calves under one year, and in the Al-Farfra and Baris regions. Gender did not significantly affect infection rates. Microscopic examination identified two species, Moniezia denticulata and Moniezia benedeni, with prevalence rates of 22.9 % and 14.3%, respectively. Histopathological analysis revealed severe inflammatory reactions in the intestinal tissues of infected cattle. These findings underscore the need for targeted control strategies, incorporating improved veterinary services and farmer education, to manage Moniezia infections effectively in Egypt.
