Prevalence and Whole Genome Sequence Analysis of Mycoplasma bovis Isolates From Bulk Tank Milk of Dairy Farms in Tennessee, USA.

ABSTRACT:

Background

Mycoplasma bovis mastitis is an important disease of dairy cows that causes substantial economic losses. However, its prevalence in different states in the United States (US), including Tennessee, is not well known. Furthermore, recent studies showed a high prevalence of bovine hemotropic mycoplasmas in US dairy farms.

Objectives

Determine the prevalence of M. bovis in bulk tank milk (BTM) of dairy farms in Tennessee and evaluate the genetic diversity, virulence factors, and antimicrobial resistance genes of the identified isolates. In addition, the prevalence of Mycoplasma wenyonii and Candidatus Mycoplasma haemobos in the bulk tank milk was determined.

Methods

Seventy-five BTM samples were collected from 59 dairy farms. Of the 59 farms, 56 are in Tennesse
