Hemoprotozoan diseases, ectoparasites, Predictor, Prevalence

Abstract

A four (4) months survey on hemoprotozoan diseases was conducted in indigenous and crossbred goat of Dinajpur and Chittagong district of Bangladesh. A total of 120 blood samples were collected randomly from the goats of two representative areas in two different seasons. Samples were examined by Giemsa's stained blood smear method. The effect of topography, season, age, gender, body condition score, ecto-parasitic infections (Ticks) etc. were observed during this study. Among different haemoprotozoan diseases, only anaplasmosis was detected in both indigenous and crossbred goat of both districts. The overall prevalence of anaplasmosis was 5.93% where it was recorded higher in Chittagong (7.14%) in compare to Dinajpur (4%). Moreover, anaplasmosis was predominant in summer season than rainy season. It was also revealed that adult goats showed more susceptibility to anaplasmosis than young but it was not statistically significant. Furthermore, presence of ecto-parasitic infestation in the study animals shown to have more susceptible to anaplasmosis which was statistically significant (P<0.05). In general, it could be stated that presence of ecto-parasites and season were the most important predictor in the occurrence of hemoprotozoan diseases. Finally, as it was a very limited study, we recommended further extensive study including molecular detection of such diseases and identification of specific vectors in the study areas which will assist to take necessary preventive measures against such diseases.
