A total of 200 individuals (100 with acne v...

Introduction: Asymptomatic bacteriuria (ASB) is defined as the isolation of bacterial strain in quantitative counts ≥105cfu/mL in the urine without the presence of any symptoms. The aim of this study was to investigate prevalence and pathogen microorganisms of ASB, and the most appropriate diagnostic test in the fırst trimester of pregnancy. Method...

Background: Demodex folliculorum mite infestation is associated with many diseases such as rosacea, pityriasis found with acne vulgaris, and blepharitis. Aim: In this research, the aim of this study was to investigate an association between patients who have metabolic syndrome and presence of Demodex folliculorum. Patients/methods: This resear...

Purpose: The Pap smear is a routine screening test for the detection of cervical abnormalities viral, bacterial, and fungal infections of the uterine cervix, The aim of this study is to investigate if Pap smear is an alternative to cervicovaginal culture in the diagnosis of asymptomatic Candida. Materials and Methods: A retrospective analysis of 13...

Background Incidence of mycobacterial infections has been increasing. However, diagnosis and treatment of mycobacterial infections can be difficult. The aim of this study was to investigate high‐performance liquid chromatography (HPLC) analysis of the mycolic acids for rapid identification and dendrogram cluster analysis of mycobacterium species....

Hafnia alvei is a rarely s een p athogen i n humans. In this article, we present a 58-year-old male case of Hafnia alvei with respiratory impairment due to a severe lower respiratory tract infection. Chest X-ray and computed tomography showed consolidation and significant infiltration in the right lung. Cultures of sputum were positive for Gram-neg...

Candida spp. are the most common opportunistic mycosis worldwide. Although Candida albicans is the most common cause of urinary tract infections, the frequency of non-albicans Candida species is increasing with common use of antifungal in the prophylaxis and treatment. This may lead to difficulties in treatment. Antifungal tests should be applied w...

Background: Staphylococci are one of the most common pathogens in nasocomial and community-acquired infections. Methicillin-resistant staphylococci are known to be resistant against all beta-lactam antibiotics. Therefore, non-beta-lactam antibiotics such as macrolide and lincosamides can be used. Resistance to those antibiotics may lead to therape...

Amaç: Pseudomonas aeruginosa özellikle hastanede yatan hastalarda ve bağışıklık sistemi zayıflamış bireylerde ciddi ve hayatı tehdit edici enfeksiyonların iyi bilinen bir etkenidir. Bu çalışmanın amacı P. aeruginosa suşlarında antibiyotik duyarlılık profilinin belirlenmesidir. Yöntem: Eylül 2011 – Nisan 2013 arasında hastanemize başvuran hastaların...

Amaç: Escherichia coli komplike olmayan üriner sistem infeksiyonlarında (ÜSİ) en sık karşılaşılan etkendir. Tedavisinde sıklıkla tercih edilen antibiyotiklere son yıllarda artan oranlarda direnç bildirilmektedir. Bu çalışmada komplike olmayan ÜSİ etkeni olan E. coli infeksiyonlarında tedavide alternatif olarak değerlendirilebilecek olan fosfomisini...

Brucellosis is a zoonotic infectious disease that can affect many organs and systems and leads to very different clinical circumstances. Brucellosis is rare in association with various infectious agents. Fascioliasis is a zoonotic disease caused by Fasciola hepatica, popularly referred to as a large leaf-shaped liver fluke. This case is a 39-year-o...

Objectives: The aim of this study was to investigate in vitro susceptibility of fusidic acid to clinic isolates of staphylococci. Materials and methods: The forty-one coagulase negative staphylococci (CNS) and 18 Staphylococcus aureus strains isolated from various clinical specimens were included in this study.
