Expression of three virulence-related genes in leptospiral strains of serogroup sejroe after weekly subcultures

Landerson Lucas Rodrigues Correia, L. V. Malliagros, Tommy Figueiredo Brasil, Bruno Cabral Pires et autres

Bovine leptospirosis is characterized mainly by reproductive problems associated with infections by strains of serogroup Sejroe. Pathogenic strains belonging to same serogroup could present differences in pathogenicity, suggesting existence of unknown molecular mechanisms involved in virulence. Furthermore, it is known that subculture …
