Abstract

BackgroundMycoplasma bovis (M. bovis) is a highly contagious cattle pathogen spreading worldwide and especially in Ningxia Hui Autonomous Region in China.ResultsTwo types of ST, ST10and ST134, were identified in Ningxia Hui Autonomous Region. Thirty-seven strains belonged to ST10 and 28 strains belonged to ST134. ST134 was a new ST and first found in 2009 and was only widely distributed in Ningxia Hui Autonomous Region at present. The M. bovis ST10 was widely spread in many provinces in China and was widespread in Ningxia Hui Autonomous Region since 2010. It is speculated that the prevalence of M. bovis ST10 in Ningxia Hui Autonomous Region began in 2010.ConclusionsThis study is the first report on the genetic diversity of M. bovis from 2009 to 2018 in Ningxia Hui Autonomous Region and provides the epidemiological information. These results may help further our understanding of the evolution of M. bovis and provide information that may be useful for the development of novel vaccines.

Summary

Introduction

Mycoplasma bovis (M. bovis) is a highly contagious cattle pathogen spreading worldwide and especially in Ningxia Hui Autonomous Region in China. Mycoplasma bovis (M. bovis) is an important pathogen causing severe pneumonia, mastitis, and arthritis in the world. Pneumonia caused by M. bovis has high morbidity and mortality. It is becoming one of the most widely recognized pathogens in the world[1, 2]. The pathogen is highly contagious and can spread rapidly throughout the herd. M. bovis can cause pneumonia, mastitis, arthritis, and otitis and induce postpartum infection of the uterus with a mortality rate of.
