Chrysomya Bezziana Infestation Epidemiological Study in Dhi-Qar Ruminants

This study investigated the epidemiology and clinical characteristics of Chrysomya bezziana infestation in ruminants in selected districts of Dhi-Qar city, Iraq. Over the study period, 623 ruminants 60 cows, 545 sheep, and 18 goats were examined, revealing varying infestation rates across species, with sheep being the most susceptible 87.4%, followed by cows 9.6% and goats 2.8%. Clinical signs included abrasion wounds, reduced appetite, weight loss, and nasal discharge. Inadequate shearing practices among sheep contributed to heightened susceptibility. The findings emphasize the importance of targeted control measures and improved husbandry practices to mitigate the economic and welfare impacts of screwworm infestation in ruminant populations, underscoring the need for further research to develop effective prevention and control strategies.
