The impact of refugees on leishmaniasis in Turkey: a new Syrian/Turkish Leishmania tropica population structure described by multilocus microsatellite typing (MLMT).

Turkey is one of the leishmaniasis endemic countries, and according to the recent reports, more than 45% of the cases were reported from the Southeastern part of Turkey. The disease is endemic in Syria with annually 25,000 cases, and it is emphasized by WHO that the actual number was estimated to be 2-5-fold higher than the reported numbers. Due to the civil war in Syria, more than seven million people were displaced and migrate to neighboring countries.

Leishmaniasis in Istanbul; A new epidemiological data about refugee leishmaniasis.

[Investigation of high-risk ST131 clone in ESBL-producing Escherichia coli isolates isolated from urine and non-urinary clinical specimens with MALDI-TOF MS and real time PCR].

In recent years, the ST131 clone was identified as a high risk pandemic clone among Escherichia coli isolates by multilocus sequence typing (MLST) studies and has been associated with extended spectrum beta-lactamase (ESBL) production (often with CTX-M-15) and antibiotic resistance especially against fluoroquinolones. The aim of this study was to determine the rate of high risk ST131 clone in ESBL producing E.coli isolates in our region, to investigate the sensitivity of MALDI-TOF MS in the detection of ST131 clone, and to compare the frequency of antimicrobial resistance among ST131 and non-ST131 isolates.

[Results of a multicenter study investigating plasmid mediated colistin resistance genes (mcr-1 and mcr-2) in clinical Enterobacteriaceae ısolates from Turkey].

Colistin is a polymyxin antibiotic which is considered as one of the last line agents against infections due to multidrug resistant or carbapenem resistant gram-negative pathogens. Colistin resistance is associated with chromosomal alterations which can usually cause mutations in genes coding specific two component regulator systems. The first plasmid-mediated colistin resistance gene, mcr-1 was described in Escherichia coli and Klebsiella pneumoniae isolates in December 2015 and followed by another plasmid-mediated colistin resistance gene mcr-2 in 2016.

Molecular characterization of carbapenem- resistant Enterobacteriaceae yields increasing rates of NDM-1 carbapenemases and colistin resistance in an OXA-48- endemic area.

We aimed to characterize carbapenem-resistant isolates in a tertiary hospital in Istanbul, Turkey, high-prevelance area for OXA-48 producers. About 76 Enterobacteriaceae clinical isolates were included. Carbapenemase production was detected by Carbapenem Inactivation Method and carbapenemase genes were investigated by PCR.

Is there any difference in tetanus IgG levels of diabetic patientswith respect to the presence of foot ulcers?

Background/aim: The aim of this study was to reveal the tetanus immunization status of diabetic patients and to determine whether diabetic patients with foot ulcers have different TIG levels.

Materials And Methods: A cross-sectional study was designed that included diabetic patients with foot ulcers (n = 30) and diabetic patients without ulcers (n = 30). The groups were compared for serum TIG levels along with total serum protein, albumin, C-reactive protein (CRP), and total immunoglobulin G (Ig G).

[Investigation of the frequency and distribution of beta-lactamase genes in the clinical isolates of Acinetobacter baumannii collected from different regions of Turkey: a multicenter study].

The diversity and distribution of TEM, SHV and CTX-M type of extended-spectrum beta-lactamases (ESBLs) are important for the treatment and control of infections. Determination of ESBL genes in clinical isolates by polymerase chain reaction (PCR) and DNA sequencing can obtain useful data for their molecular epidemiology and risk. The aim of this study was to investigate the frequency of beta-lactamase genes in Acinetobacter baumannii strains isolated from different regions of Turkey.

[Characterization of class 1 and class 2 integron gene cassettes in Escherichia coli strains isolated from urine cultures: a multicenter study].

Escherichia coli is the most common pathogen isolated from both nosocomial and community acquired urinary tract infections. Although there are many studies from different centers concerning the antibiotic susceptibility of E.coli isolates in Turkey, the studies are quite few about class 1 and class 2 integron cassettes in clinical E.

Causative pathogens and antibiotic resistance in children hospitalized for urinary tract infection.

Background: Urinary tract infections (UTI) are one of the most common bacterial infections in children and a major cause of hospitalization.
