چکیده انگلیسی

Here, we conducted an epidemiological study in five regions in central China to assess the impact of theileriosis on small ruminants. PCR analysis and microscopic evaluations of blood smears to detect ovine and caprine theileriosis was conducted, in which 256 blood samples and 250 ticks were collected from sheep and goats, and tested for Theileria uilenbergi, T. luwenshuni, and T. ovis. The 18S rRNA gene sequences were deduced from positive samples and used for phylogenetic analysis. The results showed that T. luwenshuni was found most frequently in the five investigated regions and the prevalence of T. luwenshuni was found to be very high by PCR analysis. In contrast, T. uilenbergi and T. ovis infections were not detected in these regions. Phylogenetic tree analysis showed that all of the newly isolated Theileria spp. was in the same clade as T. luwenshuni. Haemaphysalis longicornis, which can transmit T. luwenshuni, was also detected in the sampled sheep and goats in these regions. Our results provide important data to increase the understanding of the epidemiology of ovine and caprine theileriosis, and will aid in the implementation of measures to control theileriosis transmission to small ruminants in central China.
