ABSTRACT
A One year eventual study was conducted to detect the prevalence and feasible risk factors of myiasis in various species of animal in different areas of Chittagong, Bangladesh from March 2012 to February 2013. By Cross–questioning over animal rearers and with clinical examinations myiatic cases were identified and varied risk factors were distinguished. 226 cases were noted manifesting signs of myiasis. Prevalence rates were goat 69% and cattle 22%; wherever seasonal prevalence was explored highest in autumn (55.5%) than cold (11.6%) (p>0.05). Statistically significant difference in the prevalence was reputed with breed, age, sex, wound depthness, temperature and attitude of animal (p ≤0.05). Above 6 months aged animals (75.5%) and cross breeds (34.2%) were mostly infected where females (64.5%) were more prone to myiasis. Foul odorous abscess with wound, breach after delivery, umbilical infection, dirtiness, fecal and urine contamination, bed sore were the most habitual risk factors, though findings were not significant (p >0.05). Most exposed sites were vagina and perineal region, inter digital space, tail, brisket, navel, scrotum, inguinal region and gum. The study has remarked probable health hazards caused by flies in animal that will promote animal rearers in avoiding and clinically managing them. Additional widespread studies are suggested as molecular identification of species of flies and economic analysis caused by myiasis.
