“…argenteus has an average nucleotide identity of 87.4%, corresponding to a DNA-DNA hybridization value of 33.5% compared to S. aureus [12,14]. S. argenteus shares most of the major virulence factors of S. aureus, such as staphylococcal enterotoxins (SEs) [15] Antimicrobial resistance genes such as mecA have also been found in S. argenteus [16,17] indicating the presence of mobile genetic islands and horizontal gene transition.…”

Background: Staphylococcus argenteus is a new specie positive coagulase staphylococci. We investigate the presence of S. argenteus in isolates previously classified as S. aureus, obtained from the milk of cows with mastitis in Brazil. Results: Among 856 S. aureus tested in chocolate agar, tryptone soya agar and salt egg yolk agar, white or colorless colonies were observed in 185 (21.6%) isolates. Regarding the ctrOPQMN operon, 111 (60%) presented the complete cluster. Despite some missing genes in this cluster, the remaining strains (74) were confirmed as S. aureus using the nrps gene. Conclusions: As far as we know, this is the first review of S. aureus collection in Brazil and S. argenteus does not appear to be a significant problem in Brazilian herds.
