“…In this research, 40 strains were isolated from sick children, 10 strains from nurses' hands and 5 strains from the equipment [20] Another research was done in 2005; in this research 103 strains of Staphylococcus aureus were isolated from community, hospital and patients with granulomatous. 12 strains out of 51 strains isolated from community, 5 strains out of 34 strains isolated from hospital and 4 strains out of 16 strains isolated from patients with granulomatous reported presence of tst gene [21]In the present research, 29 strains out of 35 strains isolated from the patients, 5 strains out of 6strains isolated from the personnel and 15 strains out of 20 strains isolated from the equipment included tst gene. Moreover, 16 strains out of 35 strains isolated from the patients, 4 strains out of 6 strains isolated from the personnel and 8 strains out of 20 strains isolated from the equipment included eta gene.…”

Staphylococcus aureus is the most common pathogenic organisms in the hospitals and communities' infections. It is responsible for more than 80 percent of infectious diseases. The purpose of the present paper is to determine the incidence of Staphylococcus pathogenic genes isolated from different wards of hospitals by PCR method. This study included 61 Staphylococcus aureusisolates collected from different wards hospital, between 2011 and 2012 in University of Kurdistan (Toohhid and Besat hospitals). All isolates were previously identified as Staphylococcus aureusby a standard microbiological procedure. It isolates were incubated at 37Ċ for 24h on blood agar; single colonies were tested with tube and slide coagulase, catalase tests and growth on Manito salt agar. Following genomic DNA extraction, the presence of ETA, TSST-1 genes was analyzed by PCR.61 strains of Staphylococcus aureushave been isolated from different wards of the hospital. Frequency of tst gene was 81% and eta gene was 47%. Moreover, frequency of strains with both eta and tst genes was 40%. Results of the present paper indicate that the prevalence of Staphylococcusaureus results on prevalence of eta and tst genes, and this is a matter of concern.

“…In this study, agr IV was not found in any isolates, similar to what was observed in a previous report 29 , suggesting that the agr IV S. aureus isolate was not common. The agr III and IV groups were associated with tst and exfoliatin toxin production, respectively 30,31 . The tst gene was most common in the agr II S. aureus isolates (59%), followed by the agr III (27%) and agr I (14%) isolates.…”

Staphylococcus aureus is the most common cause of nosocomial fevers. We investigated the virulence genes and genotypes of S. aureus strains isolated from bloodstream infections of patients in a Thai teaching hospital. Thirtythree methicillin-resistant S. aureus (MRSA) and 52 methicillin-susceptible S. aureus (MSSA) collected during 1997-1998, and 29 MRSA and 52 MSSA strains collected during 2010-2011 were studied. Susceptibility to 8 antimicrobials was determined using an agar dilution method. Twelve virulence genes were detected by polymerase chain reaction. The bacterial strains were typed by SCCmec, agr, spa, and multilocus sequence typing. The majority of the MSSA isolates were susceptible to almost all antimicrobials tested, whereas the MRSA isolates were resistant to more than 3 of the antimicrobials tested. The hla-sea was the most common virulence gene profile in the MRSA isolates from both periods (46% in 1997-1998, 31% in 2010-2011), and hla alone was the most common pattern in the MSSA isolates (56% in 1997-1998, 35% in 2010-2011). The S. aureus isolates in 2010-2011 contained more virulence gene profiles than those in 1997-1998. All MRSA isolates from 1997-1998 carried SCCmec III-agr I, whereas those in 2010-2011 carried SCCmec III-agr I (48%) and SCCmec type II-agr II (31%). No specific virulence genes or genotypes of the isolates related to a poor clinical outcome were found.
