摘要: The cyst-forming protozoan parasite Neospora caninum is one of the main causes bovine abortion worldwide and great economic importance in cattle industry. Recent studies have revealed extensive genetic variation among N. isolates based on multilocus microsatellite genotyping. Currently, most study reported genotyping 96 samples from four countries two continents (Spain, Argentina, Germany Scotland) that demonstrate different clusters genotypes (MLGs) implicated abortions as well population sub-structuring caninum, which partially associated with geographical origin. aim this was to genotype aborted foetuses originated Mexico within region Aguascalientes investigate their diversity. Parasite DNA detected 27 out 63 analysed recovered 10 herds. Complete or nearly complete profiles 9 markers were obtained 11 samples. Diverse MLGs occurrence each herd. All Mexican differed previously determined for Argentinean, Spanish, German Scottish populations. failed cluster by eBURST analyses. MLG relationships using PCoA showed a close relationship between Spanish portion population, but more distant Argentinean genotypes. These results diversity studied areas other populations around world.
