Distribution of enterotoxin genes among carriage- and infection-associated isolates of Staphylococcus aureus.

Aims: To compare the distribution of genes encoding classical and newly described enterotoxins among Staphylococcus aureus, associated with carriage and infection.

Methods And Results: Forty-five nasal isolates from carriers and 42 clinical isolates were included. The genes sea to see and seg to sei as well as sem, sen, seo and seu were tested using multiplex and conventional PCR.

Distribution of virulence genes of Staphylococcus aureus isolated from stable nasal carriers.

In the present study, we report data on virulence determinants of Staphylococcus aureus from stable nasal carriers, emphasizing on the genes encoding fibronectin (fnbA, fnbB) and collagen (cna) adhesive molecules. Of the 44 S. aureus isolates included, 32 isolates (16 pairs) were cultured from the anterior nares of 16 healthy carriers, eight isolates (four pairs) were collected from the nose of four patients with recurrent skin infections and four isolates were obtained from the infection site of these patients.

The significance of nasal carriage of Staphylococcus aureus as risk factor for human skin infections.

The present study was designed to investigate the significance and the relationship between nasal carriage of Staphylococcus aureus and staphylococcal skin infections. Thirty-one S. aureus strains, isolated from 12 patients with chronic and recurrent skin infections, one patient with septicemia and one patient with otitis externa were studied.

[Activity of vancomycin and teicoplanin against clinical isolates of Staphylococcus aureus in the period 1994-1999].

Since the emergence of the methicillin-resistant S. aureus (MRSA) in the 1960's, glycopeptides (Vancomycin and Teicoplanin) has been the drugs of choice and commonly the sole antimicrobial agents available for the treatment of serious MRSA and other Gram-positive infections. The emergence of S.
