Macrolide-lincosamide-streptogramin resistance phenotypes and genotypes of coagulase-positive Staphylococcus aureus and coagulase-negative staphylococcal isolates from bovine mastitis
BACKGROUND There are limited data available on macrolide-lincosamide-streptogramin (MLS) resistance of Staphylococcus aureus (S. aureus) and coagulase-negative staphylococci (CoNS) from bovine milk in China. To address this knowledge gap, MLS resistance was determined in 121 S. aureus and 97 CoNS isolates. Minimum inhibitory concentrations (MICs) of MLS antibiotics were determined by an agar di...
متن کاملAn association between milk and slime increases biofilm production by bovine Staphylococcus aureus
BACKGROUND Staphylococcus aureus is associated with chronic mastitis in cattle, and disease manifestation is usually refractory to antibiotic therapy. Biofilm production is a key element of S. aureus pathogenesis and may contribute to the treatment failure that is consistently reported by veterinarians. Minas Gerais State is the largest milk-producing state in Brazil, and the characterization o...
متن کاملSlime Production and Biofilm Forming Ability by Staphylococcus Aureus Bovine Mastitis Isolates
Some Staphylococcus aureus strains, identified as causative agents of mastitis in cattle, exhibit the ability of producing a viscous extracellular polysaccharide layer (slime), which is nowadays considered to be a virulence factor, as it promotes bacterial adhesion onto the mammary epithelial cells and protects bacteria from opsonization and phagocytosis. Some strains of this genus are believed...

Skalka B.: Bacteriocin Activity of Staphylococcus aureus, Staphylococcus intermedius and Coagulase-n.egative Staphylococcal Strains. Acta vet. Brno, 55, 1986: 65-72. A total of 567 staphylococcal strains was examined for bacteriocin activity. It contained 367 S. aureus strains, 114 S. intermedius strains, and 86 coagulasenegative staphylococci belonging to ten species. The deferred method was e...
متن کاملIdentification of slide coagulase positive, tube coagulase negative Staphylococcus aureus by 16S ribosomal RNA gene sequencing.
AIMS To ascertain the clinical importance of a strain of slide coagulase positive but tube coagulase negative Staphylococcus species isolated from the blood culture of a 43 year old patient with refractory anaemia with excessive blasts in transformation who had neutropenic fever. METHODS The isolate was investigated phenotypically by standard biochemical methods using conventional biochemical...
