Insight into the genetic diversity of Anaplasma marginale in cattle from ten provinces of China.

ABSTRACT:

Background

Anaplasma marginale is an important tick-transmitted rickettsial pathogen of cattle, with worldwide distribution and an important economic impact. The genetic diversity of A. marginale strains has been extensively characterized in different geographical regions throughout the world, while information is limited on studies in China. This study was carried out to determine the prevalence and genetic diversity of A. marginale strains in cattle from ten provinces of China.

Methods

A total of 557 blood samples from cattle were collected and screened for the occurrence of A. marginale by PCR based on the msp4 gene. The partial msp1a gene containing tandem repeat sequences was further amplified from msp4 positive samples. The Msp1a amino acid repeats were identified, and
