Abstract

Here, we present the draft genome sequences of four Staphylococcus aureus strains isolated from mastitic milk collected from animals with subclinical manifestations. Three of them were typed as sequence type 126 (ST126), a genotype with no genome sequence available. ST126 is found in several herds of southern Brazil and is described as a bovine pathogen strongly associated with milk around the world.

Highlights

  • Staphylococcus aureus is one of the main pathogens isolated from bovine mastitis infections [1]

  • Intense efforts have been made to understand the molecular mechanisms of bacterial pathogenesis [2, 3] and to link bacterial characteristics with the specific clinical manifestations of bovine mastitis [4]

  • Bacteria identified as S. aureus were genotyped by multilocus variablenumber tandem-repeat analysis (MLVA) and pulsed-field gel electrophoresis (PFGE)

Summary

Introduction

Staphylococcus aureus is one of the main pathogens isolated from bovine mastitis infections [1]. Intense efforts have been made to understand the molecular mechanisms of bacterial pathogenesis [2, 3] and to link bacterial characteristics with the specific clinical manifestations of bovine mastitis [4]. We monitored two herds in the State of Minas Gerais, Brazil, for the presence of subclinical mastitis for 6 months.
