Genotypic and phenotypic detection of capsular polysaccharides in Staphylococcus aureus isolated from bovine intramammary infections in Argentina.
(Sociedade Brasileira de Microbiologia, 2012-07)
Staphylococcus aureus (n=157) isolated from intramammary infections in Argentine dairy areas were evaluated for presence of cap5 and cap8 loci. Isolates carrying cap5 and cap8 were serotyped using specific antisera. Sixty ...
Staphylococcus aureus adaptation to the host and persistence: Role of loss of capsular polysaccharide expression
(Future Medicine, 2010-12)
A vast array of virulence factors enable Staphylococcus aureus to readily adapt to different environmental niches in diverse hosts. The cap gene cluster is present in almost all relevant clinical S. aureus isolates and ...
Salicylic acid diminishes Staphylococcus aureus capsular polysaccharide type 5 expression
(American Society for Microbiology, 2010-03)
Capsular polysaccharides (CP) of serotypes 5 (CP5) and 8 (CP8) are major Staphylococcus aureus virulence factors. Previous studies have shown that salicylic acid (SAL), the main aspirin metabolite, affects the expression ...
Genotypic and phenotypic detection of capsular polysaccharide and biofilm formation in Staphylococcus aureus isolated from bovine milk collected from Brazilian dairy farms
(2016-12)
Staphylococcus aureus is a pathogen that frequently causes mastitis in bovine herds worldwide. This pathogen produces several virulence factors, including cell-associated adhesins, toxic and cytolytic exoproteins, and ...
Preparation and characterization of a Staphylococcus aureus capsular polysaccharide-protein conjugate prepared by a low cost technique: a proof-of-concept study
(2015-01)
Staphylococcus aureus is a worldwide distributed pathogen that produces several diseases in many species and is the major cause of mastitis in dairy cows. S. aureus capsular polysaccharide 5 (CP5) has been widely proposed ...
Mutation of Agr is associated with the adaptation of Staphylococcus aureus to the host during chronic osteomyelitis
(Frontiers Media SA, 2018-02)
Selection pressures exerted on Staphylococcus aureus by host factors may lead to the emergence of mutants better adapted to the evolving conditions at the infection site. This study was aimed at identifying the changes ...
Survey of potential factors involved in the low frequency of CP5 and CP8 expression in Staphylococcus aureus isolates from mastitis of dairy cattle from Argentina, Chile, and Uruguay
(2018-08)
Staphylococcus aureus produces capsular polysaccharides (CPs) both in vivo and under defined culture conditions being serotypes 5 and 8 the most prevalent. S. aureus isolates that fail to produce CP5 or CP8 are defined as ...
Survey of potential factors involved in the low frequency of CP5 and CP8 expression in Staphylococcus aureus isolates from mastitis of dairy cattle from Argentina, Chile, and Uruguay
(Polish Academy of Sciences, 2018-08)
Staphylococcus aureus produces capsular polysaccharides (CPs) both in vivo and under defined culture conditions being serotypes 5 and 8 the most prevalent. S. aureus isolates that fail to produce CP5 or CP8 are defined as ...
Streptococcus pneumoniae galU gene mutation has a direct effect on biofilm growth, adherence and phagocytosis in vitro and pathogenicity in vivo
(Oxford University Press, 2018-10)
Streptococcus pneumoniae, the most common cause of bacterial pneumonia, has developed a wide range of virulence factors to evade the immune system of which the polysaccharide capsule is the most important one. Formation ...
Cell autoaggregation, biofilm formation, and plant attachment in a sinorhizobium meliloti lpsB mutant
(American Phytopathological Society, 2018-10)
Bacterial surface molecules are crucial for the establishment of a successful rhizobia-legume symbiosis, and, in most bacteria, are also critical for adherence properties, surface colonization, and as a barrier for defense. ...
