Pathogenicity of Boophilus Species Hard Tick among Engorged Female in Naturally Infested Cattle with Ixodidae Piroplasmosis in Sulaimani Province-Kurdistan Region/ Iraq.


Isolated seventy-five cattle (female local breed) infested naturally with Ixodidae, identified into three genera: Boophilus, Hyalomma and Rhipicephalus. According to chi-square test for independence, shows highly significant value 50.75** which compared to tabular chi-square, it means that there were an association between the genus of hard tick in different locations with cattle groups. The prevalence rate of Boophilus spp. was the highest 286 (52.8%) followed by Hyalomma spp. 173 (32%) and Rhipicephalus spp. as the lowest 82 (15.2%). When using chi-square test, the overall prevalence rate of Piroplasmosis in all three types of Boophilus spp. examination were 4.9%, whereas; in adult female hymolymph 8 (10.7), followed by histological examined 2 (2.7%) than larva hymolymph 1 (1.3) with still the Anaplasma spp. the highest prevalence 54.5% followed by Babesia spp., 4 (36.4%), than in Theileria spp., 1 (9.1%) in all examination occurred in Boophilus spp., and shows not significant differentiation in their investigation among the hemolymph examined in adult and larva stage and histological examination. The prevalence rate of piroplasmosis in cattle (blood smear examined) was equally distributed and a not significant difference shows among different locations. According the chi- square test for independence, nonetheless that the result shown, the highest prevalence of piroplasmosis observed with blood smear 18.7%, whereas; Anaplasma spp. 9 (12 %), followed the Theileria spp., 3 (4 %) than the Babesia spp., 2 (2.7%) as a lowest. The prevalence rate of infection with piroplasmpsis in cattle blood smear infested with hard ticks was higher than hemolymph and histological cutters examined.
