PREVALENCE AND RISK FACTORS OF MYIASIS AT SOME SELECTED AREAS OF CHITTAGONG OF BANGLADESH AND TAMIL NADU STATE OF INDIA.

Abstract

ABSTRACT A prospective study for nine months was undertaken to estimate the prevalence and probable predisposing and risk factors of myiasis in different species of animals at some selected areas of Chittagong Division of Bangladesh as well as Tamil Nadu state of India from February, 2014 to October 2014. A total of 178 cases were identified manifesting signs of myiasis. By extensive cross-questioning of animal owners, farmers and attendants and scientific clinical examinations different pre-disposing factors and probable other risk factors were noted. The prevalence rates were recorded 59% in goat and 26% in cattle. In addition, the seasonal prevalence was explored the highest in autumn (55.5%) than the winter (11.6%). Statistically significant difference in the prevalence was noted with breed, age, sex, depth of wound, body temperature and general attitude of animal. Above 6 months aged animals (69.8%) and cross breeds (35.5%) were mostly infected where females (62.5%) were more prone to myiasis. The study attempted to addres the probable health hazards caused by flies in different animals that will benefit the veterinarians, farmers and animal owners in avoiding and clinically contain them as well. Further extensive studies are recommended as molecular identification of species of flies and economic analysis caused by myiasis in these selected areas.
