Pneumocystis jirovecii, HIV/AIDS ve immün sistemi baskılanmış hastalarda Pneumocystis pnömonisine (PCP) neden olan atipik bir fungustur. PCP profilaksi ve tedavisinde sülfa ve sülfon grubu içeren ilaçlar yaygın olarak kullanılır. Özellikle trimetoprim sulfametoksazol (TMP-SMX)’un, uzun süreli kullanılması P.jirovecii dihidropteroat sentaz (DHPS) geninde ilaç direnci ile ilişkili belirli nokta mutasyonlara neden olmaktadır. Ayrıca, DHPS ve mitokondriyal büyük alt birim [mitochondrial large subunit (mtLSU)] rRNA genotip karakterizasyonu P.jirovecii epidemiyolojisi hakkında önemli veri sağlamaktadır. Bu çalışmada, Mersin Üniversitesi Hastanesinde, immün sistemi baskılanmış hastalardan izole edilen P.jirovecii izolatlarının DHPS ve mtLSU rRNA gen bölgesi polimorfizmlerinin araştırılması amaçla...

Amaç: Toksoplazmoz zorunlu hücre içi paraziti olan Toxoplasma gondii tarafından oluşturulan bir enfeksiyondur. Genellikle asemptomatik seyretmekle birlikte, immün sistemi baskılanmış kişilerde ve gebelerde yaşamı tehdit eden enfeksiyonlara neden olabilmektedir. Çalışmada, Tıbbi Mikrobiyoloji Anabilim Dalı Laboratuvarı’na toksoplazmoz şüpheli hastalardan gönderilen kan örneklerinde anti-T. gondii IgG, IgM ve IgG avidite test sonuçlarının retrospektif olarak değerlendirilmesi amaçlanmıştır. SUMMARY Retrospective Evaluation of One-Year Results of the Toxoplasma gondii IgG Avidity in a University Hospital Objective: Toxoplasmosis is an infection caused by Toxoplasma gondii which is an obligate intracellular parasite. It generally courses as an asymptomatic infection, but it can lead to life th...
Purpose: The aim of this study was to evaluate the bacterial species distribution and antibiotic susceptibility in blood cultures obtained from patients in a secondary care center in Mersin, Türkiye.
Materials and Methods: Blood culture specimens of inpatients sent to the microbiology laboratory between January 2022 and December 2023 were retrospectively analyzed to determine the etiologic agents of bloodstream infections and to evaluate their antimicrobial susceptibility. Samples were processed using the BD Bactec FX40 automated blood culture system (BD, USA), which allows continuous monitoring and rapid detection of microbial growth. Typing of causative agents in positive cultures and antimicrobial susceptibility testing were performed using conventional methods and the Vitek2 Compact ...
Periodontal diseases are chronic inflammatory diseases and tissue destruction increases with oxidative stress in periodontal tissues. Periodontal diseases are associated with systemic diseases such as diabetes, cardio-vascular diseases and rheumatoid arthritis by means of systemic inflammation. Sickle cell disease (SCD) is a chronic inflammatory disease in which vaso-occlusive crisis and endothelial dysfunction are present. It is not known whether the chronic systemic inflammation seen in SCD affect periodontal tissues. The aim of this study was to investigate the relationship between periodontal and systemic inflammation in children with SCD. Forty-three children with SCD and 43 healthy children were included in the study. Physical, dental and periodontal statuses were examined, blood and...
