Parasitological and Entomological Data
This is the parasitological and entomological data
Steps to reproduce
Both parasitological and entomological data in each study seasons were collected and recorded in Microsoft excel spread sheet. STATA version 14.2 computer software was applied for the statistical analysis at 95% confidence interval. The prevalence of trypanosomosis was calculated as the number of infected cattle divided by the total number of sampled animals and then multiplied by 100 (19). Those associated risk factors with a P-value < 0.25 in the Univariable logistic analysis were included in the final multivariable logistic model. The infection rates (IR) of trypanosomes in G. pallidipes was calculated as the number of microscopically positive flies divided by the total number of dissected flies and multiplied by 100 (27). The apparent density (AD) of tsetse and biting flies were expressed as the number of each type of flies per traps per day (FTD). In all cases, 95% of confidence intervals were used and p-value less than 0.05 were considered as significant (33).
