Streptococcus uberis is one of the most important mastitis-causing pathogens. Although pathogenesis and virulence factors required for intramammary infection development are not yet well established, several putative virulence-associated genes have been described. This work aimed to investigate presence ten known in S. isolated from subclinical or clinical mastitis its closely related species p...
Streptococcus pyogenes is a significant pathogen of humans, annually causing over 700,000,000 infections and 500,000 deaths. Virulence in S. pyogenes is closely linked to mobile genetic elements like phages and chromosomal islands (CI). S. pyogenes phage-like chromosomal islands (SpyCI) confer a complex mutator phenotype on their host. SpyCI integrate into the 5' end of DNA mismatch repair (MMR...
Presumptive systemic streptococcal infections were detected histologically in farmed Litopenaeus vannamei juveniles submitted from a Latin American country and the bacteria isolated. Characterization work demonstrated that the Gram-positive cocci form chains, grow aerobically and anaerobically, are oxidase- and catalase-negative, non-hemolytic, non-motile, Lancefield Group B positive and PCR po...
