Aim: To determine the microbiological etiology in critically ill neurosurgical patients with nosocomial meningitis (NM) and to show the impact of Gram-negative rods and the differences between patient characteristics and the clinical and prognostic measures in Gram-negative and Gram-positive meningitis.

Material And Methods: In this prospective, single-center study, we reviewed all adult patients hospitalized during a 12-year period and identified pathogens isolated from post-neurosurgical cases of NM. Demographic, clinical, and treatment characteristics were noted from the medical records.

Introduction: This study was aimed to determine the relationship between vitamin D and soluble vitamin D receptor (VDR) levels and brucellosis, a common infection in Turkey, in which the cellular immune system is important in the course of the disease.

Methodology: Patients who had been followed up in the Department of Infectious Diseases and Clinical Microbiology of Cukurova University Medical Faculty, having been diagnosed with brucellosis and who had no brucellosis treatment before, were enrolled in the study along with healthy controls. The participants' vitamin D and soluble VDR values were recorded.

Background: In patients with chronic hepatitis C, triple drug regimens containing a protease inhibitor, peginterferon and ribavirin were found to significantly increase sustained virologic response rates compared to dual drug regimen containing pegylated interferon and ribavirin, especially in genotype 1.

Objectives: In Turkey, telaprevir has been used since March 2013. We aimed to evaluate results of patients with chronic hepatitis C treated with telaprevir, peginterferon and ribavirin.

Background: Killer cell immunoglobulin-like receptors (KIRs) are a family of inhibitory and activating receptors expressed by natural killer (NK) cells and regulate NK cell activity in the innate response against viral infections. The aim of this study was to determine the possibility of KIR genes and genotypes as a candidate for susceptibility to or protection against chronic hepatitis B virus (HBV) infection or spontaneous remission of the infection in a Turkish cohort.

Material And Methods: The present study was carried out on 37 patients with chronic HBV infection, 36 patients in spontaneous remission of HBV infection, and 85 healthy subjects.

In this study, we aimed to evaluate the 1-year post-treatment follow-up results of 112 patients who received pegylated interferon (PEG-IFN) for 52 weeks. HBeAg negativity/seroconversion and/or negative HBV-DNA at the end of the treatment were considered as response. Patients who had response at the end of treatment but had HBV-DNA breakthrough during 1-year follow-up were considered as relapse.

Background: This study aimed to identify the agents causing community-acquired urinary tract infections (CAUTIs) and their resistance patterns and to investigate risk factors for ESBL production.

Material/methods: Patients diagnosed at the Department of Infectious Diseases in the Cukurova University School of Medicine Hospital with CAUTI between January 2006 and April 2007 were included prospectively. Patient data were recorded and the microorganisms and their sensitivity patterns were evaluated by the university's central microbiology laboratory.

Lyme disease (borreliosis) is a systemic illness resulting from infection with the spirochete Borrelia burgdorferi. It is transmitted to humans by the bites of infected ticks belonging to several species of the genus Ixodes. After the bacteria enter the body via the dermis, most patients develop the early, localised form of Lyme disease, which is characterised by erythema migrans and influenza-like symptoms.
