Microorganisms isolated from the bile of the patients who have undergone cholecystectomy and their antibiotic resistance pattern: multicenter prospective study.

Background: Gallbladder and biliary tract infections are diseases with high mortality rates if they are not treated properly. Microbiological evaluation of perioperatively collected samples both ensures proper treatment of patients and guides empirical treatment due to the determination of microorganism susceptibility.

Aims: This study aimed to isolate the microorganisms in bile cultures from patients who underwent cholecystectomy and to determine sensitivity results of these microorganisms.

Incidence, etiology and risk factors associated with mortality of nosocomial candidemia in a tertiary care hospital in Istanbul, Turkey.

Objective: The aim of this study was to determine the incidence, etiology and risk factors for mortality of patients with nosocomial candidemia.

Subjects And Methods: This observational study was performed at Haydarpasa Numune Training and Research Hospital, a tertiary care hospital with 750 beds, between the years 2004 and 2007. Fifty defined cases with a nosocomial bloodstream infection caused by Candida species were included in the study.

The virulence factors and antibiotic sensitivities of Escherichia coli isolated from recurrent urinary tract infections.

Objective: We determined the antibiotic sensitivities of uropathogenic Escherichia coli (UPEC) strains isolated from the urine of patients who have recurrent urinary tract infections (UTIs).

Methods: Our study was carried out between November 2000 and January 2002 at the Infectious Diseases Clinic, Istanbul Haydarpasa Numune Hospital, Istanbul, Turkey. We compared the virulence factors (fimbrial adhesion, hemolysin production, motility property) of 50 strains of Escherichia coli (E.

The carriage of group B streptococci in Turkish pregnant women and its transmission rate in newborns and serotype distribution.

The prevalence of group B streptococci (GBS) colonization was studied in 500 pregnant women and their newborn infants by collecting vaginal and rectal swabs from mothers, and umbilical and throat swabs from their infants. Forty-six isolates of GBS were obtained from mothers' specimens and eight from neonates. Maternal and infant colonization rates were found to be 9.
