Antimicrobial resistance and epidemiological patterns of Streptococcus pyogenes in Türkiye.

Background: Drug-resistant Group A beta-hemolytic streptococci remain significant infectious agents globally. This study investigated the major S. pyogenes strains responsible for infections in Türkiye and their susceptibility to beta-lactam and macrolide antibiotics.

Predictive Role and Clinical Value of Serum Cytokines in COVID-19.

Objective: are clinically relevant for severity prediction and treatment of COVID-19 caused by SARS-CoV-2. We aimed to demonstrate the potential cytokines for severity prediction in the five days after symptom onset and describe the importance of serum cytokine levels for patients with different disease severity.

Materials And Methods: Hospitalized COVID-19 patients and healthy control participants were recruited, and serial sera were collected from COVID-19 patients.

Pseudomonasaeruginosa antimicrobial susceptibility profiles, resistance mechanisms and international clonal lineages: update from ESGARS-ESCMID/ISARPAE Group.

Scope: Pseudomonas aeruginosa, a ubiquitous opportunistic pathogen considered one of the paradigms of antimicrobial resistance, is among the main causes of hospital-acquired and chronic infections associated with significant morbidity and mortality. This growing threat results from the extraordinary capacity of P. aeruginosa to develop antimicrobial resistance through chromosomal mutations, the increasing prevalence of transferable resistance determinants (such as the carbapenemases and the extended-spectrum β-lactamases), and the global expansion of epidemic lineages.

COVID-19 associated bacterial infections in intensive care unit: a case control study.

We described the secondary bacterial infections (SBI) among COVID-19 patients in comparison with non-COVID-19 patients. We performed a retrospective case-control study between January 01, 2020 and April 01, 2022. Including the adult patients, who stayed ≥ 72 h in intensive care unit (ICU).

: Is it an Underestimated Cause of Urinary Symptoms in Males?

Objective: This study aimed to investigate the detection rate of by multiplex PCR test in the genitourinary samples of male patients with suspected urethritis and related symptoms.

Materials And Methods: A total of 144 male patients who presented to our department between February 2021 and October 2021, either with urinary symptoms or concerns following unprotected sex, were included in the study.A total of 128 (88.

Duration of infectious shedding of SARS-CoV-2 Omicron variant and its relation with symptoms.

Objectives: SARS-CoV-2 infections with Omicron variants have a high capability of human-to-human transmission. Nevertheless, the duration of isolation for mild cases was shortened to 5 to 7 days. We aimed to detect the duration of viral shedding among healthcare workers (HCWs) with Omicron by using viral culture.

[The Use of Resapolymyxin NP Test in Determining the Sensitivity of Colistin in Escherichia coli, and Klebsiella pneumoniae Isolates].

Colistin is used as the last choice of drug in multidrug resistant gram-negative bacilli infections; therefore, accurate detection of colistin susceptibility has gained critical importance. Unfortunately, many of the widely used and practical methods in the clinical laboratory have various limitations for the determination of colistin susceptibility. This situation has led researchers to search for new methods to determine colistin susceptibility.

Placental deficiency during maternal SARS-CoV-2 infection.

Introduction: Maternal anti-SARS-CoV-2 Spike antibodies can cross the placenta during pregnancy, and neonates born to infected mothers have acquired antibodies at birth. Few studies reported data on the histopathological changes of the placenta during infection and placental infection. SARS-CoV-2 infection may cause impaired development of the placenta, thus predisposing maternal and fetal unfavorable outcomes.

The Investigation of Malaria Cases in a Central Laboratory in İstanbul Region for a Period of Fifteen Years.

Objective: The aim of this study is to examine the cases with malaria identified in the last 15 years in a central laboratory in Istanbul and assess their clinical features in general.

Methods: A retrospective examination of the laboratory records of all malaria-suspected patients whose thin and thick smears of blood samples were examined between 2002 and 2017 was conducted. Cases diagnosed as having malaria were evaluated in terms of their personal features such as age and gender, complaints and findings at the time of diagnosis, clinical features and recent travel history to an endemic region.

Evaluation of the Carba NP Test for the Detection of Carbapenemase Activity in Bacteroides Species.

We evaluated the usefulness of the Carba NP test for rapid detection of carbapenemase activity in Bacteroides spp. The minimum inhibitory concentration (MIC) for imipenem was determined with gradient test strips, and cfiA gene was investigated by polymerase chain reaction for 27 clinical Bacteroides spp. isolates.

[Molecular epidemiology, antimicrobial resistance and characterization of extended-spectrum beta-lactamases of Salmonella enterica serotype Paratyphi B clinical isolates].

Although Salmonella enterica serotype Paratyphi B is the less frequently isolated serotype worldwide and in Turkey, it is the most common serotype in our hospital, with a marked increase in 2007. The purpose of this study was to investigate the antibiotic susceptibility and the extended spectrum beta-lactamase (ESBL) profile, and molecular epidemiology of S. Paratyphi B isolates detected in our hospital microbiology laboratory.
