Effect of HMGB1 and HBD-3 levels in the diagnosis of sepsis- A comparative descriptive study.

Sepsis is a life-threatening condition characterized by a dysregulated host response to infection. Early and accurate diagnosis of sepsis is crucial for timely intervention and improved patient outcomes. In recent years, there has been growing interest in identifying reliable biomarkers to aid in the diagnosis of sepsis.

Clinical carbapenem-resistant isolates simultaneously harboring , types and qnrS genes from the Kingdom of Bahrain: Resistance profile and genetic environment.

The prevalence of Carbapenem-resistant (CRKP) is currently increasing worldwide, prompting WHO to classify it as an urgent public health threat. CRKP is considered a difficult to treat organism owing to limited therapeutic options. In this study, a total of 24 CRKP clinical isolates were randomly collected from Salmaniya Medical Complex, Bahrain.

Perception of online and face to face microbiology laboratory sessions among medical students and faculty at Arabian Gulf University: a mixed method study.

Background: The COVID-19 pandemic has impacted all spheres of society including medical education and healthcare systems. In response to the pandemic, there has been a transition in medical education practice from traditional forms of teaching to online instruction delivery and virtual learning. Effective clinical microbiology education involves a combination of 'hands-on' practical learning and instructional delivery of scientific knowledge.

Dysregulation of human beta-defensin-3 expression in the peripheral blood of patients with sepsis.

Objectives: Sepsis is a serious medical condition caused by the body's systemic inflammatory response to infections. The antimicrobial peptides, human beta-defensins, play a key role in modulating host immune responses, and aberrant expression of human beta-defensins has been implicated in many infections and inflammatory diseases. However, little is known about the expression of human beta-defensin-3 in systemic infectious diseases.

Student Perception of Microbiology Laboratory Skills Learning Through a Problem-Based Learning Curriculum: Arabian Gulf University Experience.

Introduction: The curriculum at medical school at Arabian Gulf University is centered on small group learning and real-life problems provided to students and guiding students to learn actively. In microbiology, laboratory skills are taught in an innovative manner using mini cases and different lab sessions and are integrated with other basic sciences. This article describes the format and pattern of laboratory skills sessions conducted using PBL methods at Arabian Gulf University and discusses the perception of students towards PBL in laboratory skill learning and way forward for the same.

vacA genotypes in Helicobacter pylori strains isolated from patients with and without duodenal ulcer in Bahrain.

Background: The vacuolating cytotoxin and the cytotoxinassociated protein, encoded by vacA and cagA, respectively, are important virulence determinants of Helicobacter pylori.

Objective: The aim of this study was to perform vacA genotyping and evaluate its association with cagA genotype and clinical outcome.

Methods: One hundred and twenty H.

Campylobacter jejuni induces diverse kinetics and profiles of cytokine genes in INT-407 cells.

Objective: To examine the kinetic ability of embryonic human epithelial INT-407 cells to express messenger ribonucleic acid mRNA for various cytokines and chemokines in response to Campylobacter jejuni C. jejuni stimulation.

Methods: In an experimental single-blind study, cultured embryonic human epithelial INT-407 cells were treated with different concentrations of viable C.

Trends in antibiotic sensitivity pattern and molecular detection of tet(O)-mediated tetracycline resistance in campylobacter jejuni isolates from human and poultry sources.

This study was conducted to determine the trends in Campylobacter antibiotic resistance occurring in our setting and to assess the differences in the isolates using patterns of plasmid profiles. One hundred Campylobacter jejuni strains of human and poultry origin isolated in 2002-2003 (phase A) and 2005-2006 (phase B) in the Kingdom of Bahrain were evaluated. Susceptibility to erythromycin, ciprofloxacin and tetracycline was determined, and plasmid extraction and polymerase chain reaction detection of the tet(O) gene was carried out.

Multiplex PCR for direct identification of Campylobacter spp. in human and chicken stools.

Differentiation between Campylobacter jejuni and Campylobacter coli is problematic in clinical specimens due to fastidious growth requirements and limited biochemical tests. This study describes a rapid, multiplex PCR protocol for the direct detection and differentiation of C. jejuni and C.

Clinical relevance of virulence genes in Campylobacter jejuni isolates in Bahrain.

There are no data describing the genetic make-up of Campylobacter strains (an important aetiological agent of diarrhoea) circulating in the Arabian Gulf region. Here, the molecular characterization of two virulence genes in Campylobacter jejuni from Bahrain and the relationship with clinical infection are reported. Molecular screening for cytolethal distending toxin (cdtB) and invasion-associated marker (iam) genes was carried out on C.
