: To determine the serotype distribution of pneumococcus causing invasive pneumococcal disease (meningitidis, bacteremia and empyema) in children in Turkey, and to observe potential changes in this distribution in time to guide effective vaccine strategies. : We surveyed with conventional bacteriological techniques and with real-time polymerase chain reaction (RT-PCR) in samples of cerebrospinal fluid (CSF), blood and pleural fluid. strains were isolated from 33 different hospitals in Turkey, which are giving health services to approximately 60% of the Turkish population.

In this study, we aimed to investigate the performance of Toxin A + B (Clostridium difficile) DUO kit which detects C.

In this study, we evaluated the feasibility of a 5-hour incubation on solid medium after sub-cultivation of positive blood culture broth without any preparation steps in order to speed up the identification of bacteria.
Methods: In addition to standard laboratory protocols, a Columbia agar plate with 5% sheep blood was inoculated with 1 drop from the blood culture broth.
Background/aims: In contrast to many other studies of probiotic species, the number of publications evaluating Bifidobacterium lactis and its combinations with prebiotics as treatments for acute infectious diarrhea is limited. We investigated the synbiotic effects of B. lactis B94 plus inulin on acute infectious diarrhea.

Several chromogenic media have been proposed for the detection of ESBL producers in addition to the conventional phenotypic and genotyping methods. The aim of the present study was to evaluate the performance of Brilliance ESBL agar (Oxoid; Thermo Fisher Scientific, UK), a selective chromogenic agar for the detection of ESBL-producing Escherichia coli (E.

The Phoenix system (BD, Sparks, MD, USA) has been available since 2004 in our laboratory. This study evaluated the reliability of the Phoenix system for the detection of methicillin resistance in Staphylococcus aureus isolates in comparison to BD GeneOhm MRSA assay (Becton Dickinson Diagnostics GeneOhm, CA, USA).

View Article and Find Full Text PDFThe identification of community-acquired methicillin-resistant Staphylococcus aureus (MRSA) is becoming a hard task since colonization with MRSA is lasting for years and the number of the health care facilities other than hospitals is continuously increasing. In this study we aimed to investigate the genetic properties and health-care association of MRSA strains isolated from skin and soft tissue infections of outpatients admitted to Akdeniz University Hospital. Thirty strains were phenotypically identified as MRSA and after assessing the risk factors, 28 (93.
View Article and Find Full Text PDFImipenem and meropenem are broad spectrum antimicrobial agents that are especially useful in the treatment of nosocomially acquired Pseudomonas aeruginosa and Acinetobacter spp. infections. Previous reports have noted that susceptibility tests could show false resistance to imipenem.

After initial description in 2001 of unrelated VRE isolates, we report now the molecular characterization of a nosocomial outbreak at the Akdeniz University Hospital, Antalya, Turkey.
Methods: VRE isolates were from either clinical or rectal swab specimens.
