Abstract

A one-year epidemiological survey was conducted to determine the age, sex, and season-wise prevalence of Trypanosomiasis in dromedary camels (Camelus dromedarius) at Dera Ismail Khan region of Khyber Pakhtunkhwa, province of Pakistan. A total of 600 blood samples were parasitological examined, of which 300 were male and 300 were females. Camels have grouped age-wise as Adults (<2 years age) and calves (>2 years age), sex-wise as; male and female, while kept the ratio of animals in both age and sex group, were kept nearly 1:1. Season-wise prevalence was recorded by splitting the data into four seasons: pre-monsoon, Monsoon, Post-Monsoon, and winter. The samples were examined microscopically using thin, thick, and wet blood film to identify Trypanosoma evansi based on morphological characteristics. An overall prevalence was 6.67%. Age-wise prevalence was high at 9.06% in adults and low at 4.30% in calves (P<0.05). Sex-wise, the infestation was observed as high 7.66% in females and low 5.66% in male camels (P>0.05). Among four seasons of the year, the highest prevalence, 11.18%, was observed in the rainy season of monsoon, followed by 8.45, 7.85, and 0% in post-monsoon, pre-monsoon, and winter, respectively (P<0.05). All the results were statistically analyzed on SPSS using the Pearson Chi-Square test. This survey showed that age and season have a significant effect while sex has a non-significant effect on the prevalence of Trypanosomiasis in dromedary camels.
