Sheep (ovine and caprine theileriosis) theileriosis is spread by ticks protozoa genus by泰勒科泰勒, parasitic in sheep and goats macrophages , lymphocytes and erythrocytes caused diseases in general . Sheep theileriosis serious harm , sheep, lambs and in the field can cause the introduction of a large number of deaths , chronic disease of goats and sheep and development slows significantly reduced the amount of meat production and wool yield , which cause significant economic losses to the sheep industry . In China, the sheep theileriosis is a common tick-borne protozoal , mainly distributed in China 's western regions , including Gansu , Ningxia , Inner Mongolia , Qinghai, Sichuan and Shaanxi provinces . However, the the domestic sheep Taylor sporozoites is not yet comprehensive. This study of the distribution of Lu Theileria is the main object of study , to further study its biological characteristics , the main findings are as follows: the discovery of the Haemaphysalis longicornis hunger into the female ticks salivary glands , including a composition composed of three acinar species of the the type Ⅰ non- particle type acinar and two ⅱ and ⅲ type particles acini ; including the type Ⅰ acini at least by the central cells and peripheral cells ; the II type acini mainly containing ab , c1 , c2 , c4 five kinds of particles cells ; the III type acinar contains d , e, f and the three granulosa cells . Lu Theileria sporogony entire process occurs in the the III type acinar e cells . Through the ticks - bloodsucking stimulation , the sixth day of maturation . Pressure film observed a large concentration of sporozoites e cells ; suspension smears found was a purple-blue sporozoites ; approximately 386 bp fragment was amplified using specific primers , confirmed the presence of sporozoites of Lu Taylor .
