[A New Case of Fournier's Gangrene Caused by Actinotignum schaalii].

Actinotignum schaalii (formerly known as Actinobaculum schaalii) is an anaerobic or facultative anaerobic gram-positive bacillus that can be found commensally in the urogenital region. It can be overlooked because it grows slowly and is difficult to identify with classical microbiology laboratory techniques. Colonies become visible after 48-72 hours of incubation on blood agar in anaerobic or CO₂-rich media.

HCV Genotype Distribution of Patients with Chronic Hepatitis C in Istanbul.

Objectives: Hepatitis C virus (HCV), which has no protective vaccine, is a common cause of chronic hepatitis, which is a severe public health threat. There are differences in nucleotide and amino acid sequences in different regions of the HCV genome. As a result of these differences, HCV has been shown to have at least seven major genotypes and many subtypes.

Nosocomial Infection Agents of Şişli Hamidiye Etfal Training and Research Hospital: Comparison of 1995 and 2017 Data.

Objectives: Healthcare-associated infections (HCAI), which are important causes of mortality and morbidity, are high cost but preventable infections. This study aimed to determine hospital infections and isolates in Şişli Hamidiye Etfal Training and Hospital and to determine our local data. The changes in the distribution of the isolates in this process were evaluated by comparing the data of 1995 and today.

Trend in Antibiotic Resistance of Extended-Spectrum Beta-Lactamase-Producing and Bloodstream Infections.

Objectives: Extended-spectrum beta-lactamases (ESBLs) have been detected more frequently in members of the family, particularly and . Infections caused by ESBL-producing bacteria are often resistant to treatment with various antibiotic classes and accompanied by increased complication risks, mortality, and costs. In this study, blood culture results were analyzed to determine the change in the ESBL production rate and antibiotic susceptibilities in and isolates over a period of 3 years.

Clinical effect of discordance in empirical treatment of cases with urinary tract infection accompanied by bacteremia.

Objective: It has been shown in previous studies that inadequate empirical treatment is associated with mortality in a variety of infections caused by Gram-negative bacteria. In this study, the clinical effect of discordance in empirical treatment was investigated in patients with urinary tract infection (UTI) accompanied by bacteremia.

Material And Methods: We retrospectively reviewed the files of adult (>18 years old) patients who were diagnosed with UTI in our clinic between January 2014 and December 2015.

[Evaluation of Mascia Brunelli rapid antigen test in the diagnosis of group A streptococcal pharyngitis].

Pharyngitis in most cases is due to viral microorganisms however drug therapy without the detection of etiological agent leads to unnecessary use of antibiotics. On the other hand, when the etiologic agent is group A beta-hemolytic streptococci (GAS) it is important to identify the etiologic agent rapidly which will guide the treatment with appropriate antibiotics. The use of highly sensitive rapid tests will contribute significantly to early diagnosis and appropriate therapy.

Evaluation of the Carbapenem Inactivation Method for Detection of Carbapenemase-Producing Gram-Negative Bacteria in Comparison with the RAPIDEC CARBA NP.

Timely detection of carbapenemases by both phenotypic and genotypic methods is essential for developing strategies to control the spread of infections by carbapenem-resistant isolates and related morbidity and mortality. The aim of this study was to compare the performance of a commercial kit, the RAPIDEC CARBA NP, and an in-house technique, the carbapenem inactivation method (CIM), against a panel of 136 carbapenemase- and noncarbapenemase-producing Enterobacteriaceae, Acinetobacter baumannii, and Pseudomonas aeruginosa isolates. RAPIDEC CARBA NP displayed 99% sensitivity and 100% specificity, whereas the sensitivity and specificity were 78% and 100% for the CIM test, respectively.

VIM-1, VIM-2, and GES-5 Carbapenemases Among Pseudomonas aeruginosa Isolates at a Tertiary Hospital in Istanbul, Turkey.

Worldwide increase in carbapenem resistance and transferable carbapenemases are significant challenges in treatment of Pseudomonas aeruginosa infections. In this study, investigation of carbapenemase production in carbapenem-resistant P. aeruginosa isolates recovered from clinical specimens in a tertiary hospital was aimed.

Corynebacterium propinquum bronchopneumonia in a child with ataxia telangiectasia.

Nondiphtherial Corynebacterium species isolated from clinical specimens are usually considered as contaminants by many clinicians when reported by microbiologists. However, an increasing number of studies have confirmed the importance of Corynebacterium spp. in the etiology of a variety of infectious processes.
