TICK AND TICK BORNE HEMOPARASITIC DISEASES IN CROSSBRED CATTLE OF SELECTED FARM IN CHITTAGONG CITY

Abstract

The study was undertaken for a period of 52 days from 7th July, 2008 to 27th August, 2008, to measure the proportional prevalence of tick and tick born diseases (Babesiosis and Anaplasmosis). In cattle of selected farm in Chittagong city and to identify the risk factors associated with blood parasitic diseases. A total number of 117 animals were included in the study (FXL-Cross, SXL-Cross and Local were N=101, N=12 and N=4 respectively) for epidemiological study, laboratory examination, and statistical analysis. The epidemiological survey of this study was carried out using preset questionnaires, for laboratory examination peripheral blood smear from ear vein were prepared from suspected cattle (2 smears per cattle).Out of 117 animal there were found 10 positive cases in where FXL-Cross, SXL-Cross local were 9,1 and 0 respectively. Result revealed that the proportional prevalence of blood parasites was 8.54%. Host risk factors such as type of animal, breed, age, nutritional status, and environmental risk factor such as presence of ectoparasites were investigated for the possible association with the frequency of blood parasitic diseases. Of the risk factors investigated, nutritional status was very nearly significant.
