Background: The prevalence of opportunistic yeast infections has increased in recent decades as the resultof an increasing immunocompromised patient population.Aims: To evaluate ribosomal RNA (rRNA) gene sequence to identify medically important yeast species, toinvestigate the performance of both the rRNA gene internal transcribed spacer (ITS) and D1/D2 region in identifying clinically relevant yeasts, and to compare these results with those of a standard phenotypicmethod.Methods: Both regions from 50 yeast strains, comprising 45 clinical isolates and 5 reference strains, wereamplified using P ...Daha fazlası

Objective: To investigate Blastocystis’ etiologic role and association with gastrointestinal symptomatology in acute and chronic urticaria patients and to identify Blastocystis subtypes responsible for urticaria. Methods: The study included urticaria patients and healthy individuals that presented to our polyclinic between June 2015 and May 2017. The participants were assigned into Group I (137 patients), subdivided into acute (72) and chronic urticaria patients (65), and Group II (129 control individuals). Blastocystis presence was investigated by native-Lugol examination, trichrome staining, ...Daha fazlası

tBackground: mecA is a predefined gene causing methicillin resistance in Staphylococcus aureus (S. aureus)isolates; however, it has been shown that some methicillin-resistant S. aureus (MRSA) strains do notcarry this gene. Recently, in isolates found to be MRSA-positive but mecA-negative, a new resistance gene called mecC, which is a homolog of mecA, has been reported. This study aimed to investigate the mecCand mecA genes in MRSA strains isolated from different geographic regions in Turkey.Methods: The sample of the study consisted of 494 MRSA strains isolated from seven geographical regionsi ...Daha fazlası

Lyme disease is a common tick-borne infection caused by the spirochete Borrelia burgdorferi sensu stricto (s.s.). B. burgdorferi s.s. may utilize chemotaxis, the directional migration towards or away from a chemical stimulus, for transmission, acquisition, and infection. However, the specific signals recognized by the spirochete for these events have not been defined. In this study, we identify an Ixodes scapularis salivary gland protein, Salp12, that is a chemoattractant for the spirochete. We demonstrate that Salp12 is expressed in the I. scapularis salivary glands and midgut and expression ...Daha fazlası

Candida species cause cutaneous and systemic infections with a high mortality rate, especially in immunocompromised patients. However, the emergence of resistance to the most common antifungal drugs, also due to biofilm formation, there is an increasing need to design new and more effective antifungals with less toxic. Sulfonyl hydrazones are well-known for their pharmacological effects, such as antifungal and antibacterial potential and can act as an antinociceptive, antidepressant, antineoplastic activity. The aim of this study was to investigate the anti-candidal and anti-biofilm activity o ...Daha fazlası

Background: This study aimed to investigate the prevalence of symptomatic tinea capitis infections of the scalp and its asymptomatic carriage in students attending primary schools in Erzincan, Turkey. Materials and Methods: Eighteen primary schools were visited; 1 located in the central district and 17 located in other districts of the Erzincan province. From 2015 November to 2016 April, scalp scrapings were obtained from a total of 1879 students aged 6 to 13 years (mean age: 9.37±1.69) 924 (49.2%) male and 955 (50.8%) female using sterile hairbrushes, and assessed for tinea capitis and asympt ...Daha fazlası
BACKGROUND: High asymmetrical dimethylarginine (ADMA) levels have been associated with endothelial dysfunction and contribute to the development of several diseases. However, data on the relationship between hepatitis B virus (HBV) and ADMA are limited. The aim of our study was to explore the relationship between ADMA and HBV by comparing the ADMA levels in patients with chronic active hepatitis B (CHB), inactive HBV carriers (carriers), and healthy volunteers (controls). METHODS: The participants were divided into three groups: 90 patients with CHB, 90 HBV carriers, and 90 controls. Serum ADM ...Daha fazlası

Background: We aimed to determine the geographical features and seroprevalence of Borrelia burgdorferi in Erzincan, Turkey, which has a high tick population due to its geographical position and climatic conditions. Methods: From January to December 2014, 368 people living in Erzincan, northeastern Turkey were enrolled. B. burgdorferi IgG antibodies were investigated in the collected serum samples using the ELISA method in 2015. Positive and borderline results were confirmed using the Western Blot (WB) method. Results: Borrelia burgdorferi IgG positivity was found to be 4.1% by ELISA and 2.17% ...Daha fazlası

Why most women can clear human papillomavirus (HPV) infections while others can develop permanent infections. The stimulation of immunotolerance of the immune system of the host by the persistent HPV infection may be the answer to this question. Interleukin-33 (IL-33) may play a role in the pathogenesis of HPV infection, this hypothesis was thought to be due to the rapid release of IL-33 from damaged cells following tissue damage, necrosis, and activation of the inflammasome. Thus, in this study, the role of IL33/suppressor of tumorigenicity 2 (ST2) was emphasized in HPV positive and HPV negat ...Daha fazlası
