Occurrence, Risk Assessment and Wound Healing Approach of Myiasis in Cattle and Goat in Chittagong, Bangladesh

Abstract

| The present study was conducted to determine the clinical prevalence of myiasis in cattle and goats at three veterinary hospitals of Chittagong and Cox's Bazar district, Bangladesh. During the study period overall 2270 cases were observed of which 91 cattle and goats were affected with myiasis. The disease was diagnosed by their clinical history and signs. By using a structured questionnaire several factors like rearing system, species, breed, age, sex and predisposing factors, body part affected and antimicrobials used to treat myiasis wound of each individual case were recorded and subsequently analyzed. The overall proportionate prevalence of myiasis was 4.09% of which 1.67% (n=38) in cattle and 2.42% (n=55) in goat whereas proportionate prevalence in Patiya, Ruma and SAQTVH was 5.52% (N=670), 3.65% (N=1150) and 2.55% (N=550). Younger goat less than 1 year of age had 34 (71.4%) prevalence along with a semi-intensive rearing system 38 (69.09%) showed significantly highest infestation rate. In case of cattle the highest prevalence was found in cross breed 18 (56.2%) but 23 (41.82%) in case of Jamunapari breed of goat. Frequency of myiasis was higher in the vagina (13.99%) than other body regions and the most common predisposing factors were diarrhoea (17%), parturition (12%) and omphalitis (15%). Hematological parameters revealed that eosinophils were the predominated circulation cells. During the treatment of myiasis wound of cattle and goats penicillin and streptomycin combination was used in maximum 38 (40.86%) cases. These findings bring out the wound healing approach, management and treatment of myiasis in cattle and goat within different topography in Chittagong, Bangladesh. Keywords

“…Moreover, the efficacy of drugs, in addition to their dose and prescribing pattern to treat animal diseases has not been ascertained yet in Bangladesh (Islam et al, 2003;Adieme, 2017). Earlier some studies has published drug prescribing pattern mostly concised with species specific or disease specific (Islam et al, 2012;Sarker et al, 2016b;Samad et al, 2020). So, this study aimed to estimate the proportion of use of different antibiotics and supporting drugs against a wide variety of animal diseases.…”
