Is it worth screening for vancomycin-resistant Enterococcus faecium colonization?: Financial burden of screening in a developing country.

Background: The screening of critically ill patients at high risk of vancomycin resistant enterococci (VRE) colonization, to detect and isolate colonized patients, is recommended to prevent and control the transmission of VRE. Screening asymptomatic carriers brings financial burden for institutions. In this study, we performed risk analysis for VRE colonization and determined the financial burden of screening in a middle-income country, Turkey.

Serotype distribution of Streptococcus pneumoniae in children with invasive diseases in Turkey: 2008-2014.

Successful vaccination policies for protection from invasive pneumococcal diseases (IPD) dependent on determination of the exact serotype distribution in each country. We aimed to identify serotypes of pneumococcal strains causing IPD in children in Turkey and emphasize the change in the serotypes before and after vaccination with 7-valent pneumococcal conjugate vaccine (PCV-7) was included and PCV-13 was newly changed in Turkish National Immunization Program. Streptococcus pneumoniae strains were isolated at 22 different hospitals of Turkey, which provide healthcare services to approximately 65% of the Turkish population.

The relationship between holding time and the bacterial load on surgical instruments.

The aim of this investigation was to determine the bacterial load on used instruments and to evaluate the relationship between the bacterial load and the holding time prior to cleaning. Thirty six sets were evaluated to establish the average number of bacteria per square centimeter. For the experimental study, three different bacteria were prepared in sheep blood and used to contaminate sterile stainless steel pieces with the surface of 10 cm(2).

Effect of resin infiltration on enamel surface properties and Streptococcus mutans adhesion to artificial enamel lesions.

The aim of this study was to evaluate and compare the effects of resin infiltration and sealant type on enamel surface properties and Streptococcus mutans adhesion to artificial enamel lesions. Artificial enamel lesions were produced on the surfaces of 120 enamel specimens, which were divided into two groups: Group A and Group B (n=60 per group). Each group was further divided into four subgroups (n=15 per subgroup) according to sealant type: Group I-Demineralized enamel (control); Group II-Enamel Pro Varnish; Group III-ExciTE F; and Group IV-Icon.

An unpredicted side effect of prophylactic antibiotic use.

Introduction And Objective: We investigated the effects of cefazolin sodium (CS), on wound healing in rats.

Material And Method: Forty rats in which an incisional wound model was created by removing two skin strips (4×1 cm), and suturing the wound edges, were included. Four groups were formed in a randomized way with each having 10 rats.

[Epidemiology, clinical and microbiological characteristics of invasive streptococcal infections in Turkey, 2010-2011].

A one-year active surveillance study was conducted to investigate the epidemiological and microbiological characteristics of invasive group A streptococci (GAS) infections in Turkey and to provide data for the establishment of national preventive strategies related to invasive GAS infections. A total of 46 clinical microbiology laboratories from 12 different regions of Turkey (Istanbul; Eastern and Western Marmara; Eastern and Western Blacksea; Aegean; Mediterranean; Western, Central, Northeastern, Middle-eastern and Southeastern Anatolia) participated in the study. Accordingly, GAS strains isolated from sterile body sites (blood, cerebrospinal, synovial, pleural, peritoneal, pericardial fluids) in the study centers between June 2010-June 2011, were sent to Maltepe University Hospital Clinical Microbiology Laboratory for microbiological confirmation and further analysis.

[Comparison of ertapenem-EMB Agar with traditional methods for screening carbapenem-resistant Klebsiella pneumoniae from rectal swabs].

Detection of rectal colonization with carbapenem-resistant Klebsiella pneumoniae (CRKP) is the most important step in the infection control protocols in order to prevent infections caused by CRKP which has an increasing incidence all over the world. In this study, it was aimed to compare the detection rate of 2 mg/L ertapenem EMB agar medium with the other methods recommended by various international guidelines. These methods include direct plate method using ertapenem disc, enrichment method in tryptic soy broth containing 2 mg/L ertapenem and the investigation of the predominant betalactamases in the colonized patients.

Microbiology of Brucella.

The genus Brucella is a member of family Brucellaceae and includes ten species which are small, non-motile, non-sporing, aerobic, gram-negative intracellular coccobacilli. They are catalase, oxidase and urea positive bacteria. Members of the genus can grow on enriched media like blood agar or chocolate agar.

Materials And Methods: Forty-eight eyes of 24 New Zealand white albino rabbits were divided into six groups (n=8 in each). The right eyes were divided into three groups and defined as infected group; left eyes were divided into three groups and defined as uninfected group.

Antimicrobial susceptibility and molecular subtyping of 55 Turkish Bacillus anthracis strains using 25-loci multiple-locus VNTR analysis.

Anthrax, which is caused by the bacterium Bacillus anthracis, is one of the oldest documented infectious diseases in both livestock and humans. The differentiation of B. anthracis strains is difficult because of their highly homogeneous genomes.

Locking tunneled hemodialysis catheters with hypertonic saline (26% NaCl) and heparin to prevent catheter-related bloodstream infections and thrombosis: a randomized, prospective trial.

Objective: Tunneled cuffed dual-lumen catheters (TCCs) are commonly used for vascular access in hemodialysis (HD) patients. Catheter-related bloodstream infection (CRBSI) is the major problem leading to morbidity and mortality. We investigated whether 26% NaCl solution has any favorable effect on the infections and thrombosis caused by HD catheters.

[Genotyping of nosocomial methicillin-resistant Staphylococcus aureus strains isolated from clinical specimens by rep-PCR].

Methicillin-resistant Staphylococcus aureus (MRSA) infections are associated with increased cost, mortality and length of hospital stay compared with the other infections. Therefore, controlling the spread of this pathogen by screening patients, personnel and the environment remains as a high priority in infection control programs. The aim of this study was to detect the clonal relationship between nosocomial MRSA strains by using repetitive-sequence-based polymerase chain reaction (rep-PCR) method which has several advantages owing to its speed and ease of use.

[Comparative evaluation of e-test and disk diffusion methods for susceptibility testing of Nocardia species].

Variations in antimicrobial susceptibility among different Nocardia species limit the options for therapy. It is very difficult to perform antimicrobial susceptibility testing of these bacteria due to their slow growth rate and problems in inoculum preparation. The aim of this study was to compare E-test and disk diffusion methods for the determination of antimicrobial susceptibilities of Nocardia isolates.

Changing pattern of antibiotic susceptibility in intensive care units: ten years experience of a university hospital.

The study was performed to assess microorganisms and antibiotic susceptibility patterns during ten years in intensive care units of a University Hospital. Infection Control Committee has active, prospective surveillance in ICUs for thirteen years. Ten years data of ICUs was evaluated retrospectively from surveillance forms.

Molecular typing and cdt genes prevalence of Campylobacter jejuni isolates from various sources.

The genetic diversity of 168 Campylobacter jejuni isolates originating from human (n=30), cattle (n=36), sheep (n=44), dog (n=35), and poultry (n=21) and cdt genes prevalence of the isolates were investigated.
