| 總結: | Piroplasmosis (babesiosis and theileriosis) are the leading blood parasites responsible for
significant economic losses to the dairy enterprises. These parasites are transmitted by Ixodid
ticks from a diseased animal to a healthy animal. This study was executed to determine the
prevalence of Theileria and Babesia in water buffaloes in District Dera Ismail Khan for their
risk assessment. During this trial, 350 random blood samples were obtained from buffalos
within the region of District Dera Ismail Khan and examined for Babesia and Theileria
parasites using Giemsa staining technique under an oil immersion lens. Forty-eight blood
samples were found positive and the prevalence of Babesiosis was 7.43 %, followed by the
prevalence of Theileriosis (6.28 %). Babesiosis had a significantly higher (p < 0.05)
prevalence among both males and females (6.9 % and 7.7 %, respectively) followed by
Theileria (5.38 % and 6.8 %, respectively). The significantly highest (p < 0.05) prevalence of
Theileria was seen in calves younger than 2 years (16.7 %). Babesiosis was most prevalent (p
< 0.05) in calves aged 2 to 5 (11.7 %). The Kundhi buffalo breed had the highest (p < 0.05)
prevalence of babesiosis, followed by the Nili Ravi breed, while, the Nili Ravi breed had the
highest frequency (p < 0.05)of Theileria. Piroplasmosis prevalence significantly (p < 0.05)
peaked in the summer season. Piroplasmosisis the major risk factor in endangering the
general health of the buffalo’s population, therefore, stringent control measures are
recommended for the management of the tick population.
