Staphylococcus saprophyticus hemagglutinin binds fibronectin.
Attachment of microorganisms to host tissue is regarded as an important step in the pathogenesis of infections. Staphylococcus saprophyticus adheres to various epithelial cells and hemagglutinates sheep erythrocytes. The hemagglutinin has been identified, but a human target for this surface protein is still not known. In our report, we show that hemagglutinating strains of S. saprophyticus bind...
متن کاملRecognition of Staphylococcus saprophyticus in urine cultures by screening colonies for production of phosphatase.
Phenolphthalein diphosphate was incorporated into a primary blood agar medium for use in performing quantitative urine cultures. Phosphatase-negative staphylococci, such as Staphylococcus saprophyticus, were differentiated from phosphatase-positive species, such as Staphylococcus epidermidis, by spot testing colonies on filter paper saturated with 1 N NaOH. Phosphatase-positive colonies turned ...
متن کاملIntrinsic novobiocin resistance in Staphylococcus saprophyticus.
Intrinsic novobiocin resistance in Staphylococcus saprophyticus was associated with expression of a novobiocin-resistant form of the drug target protein (GyrB). Site-directed mutagenesis established that resistance depends upon the presence of two specific amino acid residues in GyrB: a glycine at position 85 and a lysine at position 140.
متن کاملSlime production by Staphylococcus aureus strains isolated from cases of bovine mastitis.
The objective of the present research was to determine the frequency of slime production by Staphylococcus aureus strains recovered from bovine mastitis and comparison of slime formation frequency, depending on the determination procedure employed. The investigations embraced 59 Staphylococcus aureus strains obtained from the inflammatory secretion of mammary glands of 45 cows. Slime production...
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...
