Problems solved by technology

However, its use is limited when conducting large-scale censuses in areas infested by multiple species of Theileria due to cross-reaction problems between some Theileria species
Enzyme-linked immunosorbent assay (ELISA) serological tests are increasingly used to detect parasite-specific antibodies, but this method can only detect a specific species of worms alone, mainly due to the various ELISAs for detection of Theileria antibodies There is poor specificity, and ELISA, as a serological detection method, sometimes only shows whether the tested animals have been infected with pathogens

Abstract

The invention discloses a kit for identifying and diagnosing bovine theileria annulata, theileria sergenti and theileria sinensis sp.nov., a preparation method and an application method of the kit. The kit at least comprises an upstream primer of the theileria annulata and a downstream primer of the theileria annulata, an upstream primer of the theileria sergenti and a downstream primer of the theileria sergenti, as well as an upstream primer of the theileria sinensis sp.nov. and a downstream primer of the theileria sinensis sp.nov.

Description

technical field [0001] The invention relates to a kit capable of differentially diagnosing Theileria annuli, Theileria cercei and Theileria sinensis, and a preparation and use method of the kit. Background technique [0002] Bovine Theileriasis is a tick-borne disease of cattle. There are 6 types of Theileria infecting cattle, of which there are two that are the most pathogenic and cause serious economic problems, one is small Theileria and the other is Ring Theileria insect. Theileria bovis that exist in China mainly include Theileria annulus, Theileria thieri, Theileria buffalo / Theileria orientalis and Theileria sinensis. Theileria sinensis is a new species of Theileria bovis transmitted by blood ticks in Qinghai discovered by Bai Qi et al. It is mainly distributed in Gansu and Qinghai provinces in China. The main vector of Theileria bovine, the bovine tick, is widely present in tropical and subtropical countries. In view of the serious harm of this type of disease, the ...
