Drug resistant patterns of enterococci recovered from patients in Tehran during 2000–2003

Frequency of isolation and antimicrobial susceptibility of bacteria isolated from bloodstream infections at Children's Medical Center, Tehran, Iran, 1996–2000

“…Conversely, in contrast to other regions of the world, all of our enterococci were susceptible to vancomycin during the period of the present study [22,23]. However, this finding is in sharp contrast to reports by Feizabadi et al [24] who have recently shown a considerable 7% resistance rate among enterococci isolated from a small hospital in Tehran, indicating an alarming shift in vancomycin susceptibility among enterococci in Iran in recent years. Additional concern in the treatment of enterococcal infections in Iran is warranted because gentamicin resistance among our enterococcal isolates has also been shown to be much higher than the enterococci studied in other geographical areas [23,25].…”

Clonal heterogeneity of clinical isolates of vancomycin‐resistant Enterococcus faecium with unique vanS

“…Data on the prevalence of these strains are scarce in Iran, and to the best of our knowledge there is no published information concerning the genetic relatedness of VRE isolates. In 2004, the rate of VRE in Iranian hospitals was around 2% (Feizabadi et al 2004); 16% of enterococcal isolates in Iran are resistant to at least three antibiotics (Feizabadi et al 2002). Comparison of our results with the findings reported by investigators from other countries in this region suggests that the incidence of VRE in Iran is higher (Khan et al 2002;Kacmaz & Aksoy 2005).…”

Antimicrobial resistance of enterococci in Turkey

“…In the same study, 26 E. faecium strains had differing ratios of resistance to ampicillin and penicillin of 75% and 50%, respectively. There are also other reports of varying rates of penicillin and ampicillin resistance [13,14].…”
