Myasthenia gravis (MG) is a multifaceted autoimmune disorder affecting the postsynaptic neuromuscular junction. In this study, we examined CD4 and CD8 T lymphocyte levels and ratios within peripheral blood mononuclear cells (PBMCs) in MG patients. Additionally, we assessed lymphocytes for the expression of CD71, which functions as a transferrin receptor mediating the uptake of iron into the cells.

Following the emergence of severe acute respiratory syndrome coronavirus-2 (SARS CoV-2) and using only PCR for diagnosis, antibody tests have been rapidly developed by various commercial companies. There are differences between the sensitivity and specificity of these tests due to the usage of different viral target proteins and antibody subclasses. In order to evaluate the diagnostic use of these tests, we aimed to examine the diagnostic performance, especially sensitivity and specificity, of SARS-CoV-2 IgM, IgA and IgG tests of various companies (Abbott, Roche, Euroimmun, Dia.

Background: The increasing rate of infections caused by multiple drug resistant gram-negative bacteria has led to resuscitation of colistin. As a result, colistin resistance, mainly among Klebsiella pneumoniae strains has also been increased. The aim of this study was to investigate molecular mechanisms behind colistin resistance.

Background: Since Brucellosis is difficult to diagnose based on clinical symptoms, the diagnosis mostly relies on the results of serological testing. ODAK Brucella Coombs Gel Test is a novel and rapid gel microcolumn agglutination test which is performed in microcolumns containing gel matrix and Coombs antibodies. In this study, we aimed to compare ODAK Brucella Coombs Gel Test with other commonly used serological tests.

The high prevalence of Bacillus species in nature and the detection of these bacteria as contaminant in cultures may lead diagnostic dilemma, however they should still be considered as a pathogen particularly in case of repeated positive cultures from patients with risk factors. Bacillus pumilus is a bacteria, though rarely, been reported as the causative agent of various infections such as sepsis, endocarditis, skin infections and food poisoning in human. In this report, a sepsis case in an immunocompetent patient caused by B.

Background: Anaerobic bacteria play an important role in eye infections; however, there is limited epidemiologic data based on the the role of these bacteria in the etiology of keratitis and endophthalmitis. The aim of this re- search is to determine the prevalence of anaerobic bacteria in perforated corneal ulcers of patients with keratitis and endophthalmitis and to evaluate their antimicrobial susceptibilities.

Methods: Corneal scrapings were taken by the ophthalmologist using sterile needles.
