The data on the epidemiological analysis of cholera cases in the epicenter of this infection in the Daghestan, viz. in the village of Gerga, Kaiakent District, are presented. The outbreak of cholera was due to the import of this infection by pilgrims from their hajj to Saudi Arabia. The causative agent of the outbreak was the epidemic variant of V. cholerae eltor Ogawa. Everyday contacts were the main route of the transmission and spread of this infection, the water factor playing an insignificant role. Two epidemic waves of cholera were registered in Gerga, each of them provoked the penetration of the infection to other regions of the Republic of Daghestan.

Cholera rapid diagnostic tests (RDTs) are vulnerable to virulent bacteriophage predation. We hypothesized that an enhanced cholera RDT that detects the common virulent bacteriophage ICP1 might serve as a proxy for pathogen detection. We previously developed a monoclonal antibody (mAb) to the ICP1 major capsid protein.

Objectives: The objective of this study is to investigate lipopolysaccharid-binding protein (LBP), zonulin and calprotectin as markers of bacterial translocation, disturbed gut barrier and intestinal inflammation in patients with radiographic axial spondyloarthritis (r-axSpA) during tumour necrosis factor inhibitor (TNFi) therapy and to analyze the association between disease activity, response to treatment and biomarker levels.
Methods: Patients with active r-axSpA of the German Spondyloarthritis Inception Cohort starting TNFi were compared with controls with chronic back pain. Serum levels of LBP, zonulin and calprotectin were measured at baseline and after 1 year of TNFi therapy.

We studied the relationship of frailty and acute lower respiratory infection (ALRI) among a multi-site cohort of community-dwelling older adults aged ≥60 years in India. During January 2019‒January 2020, participants completed the Edmonton Frail Scale (EFS) at baseline and every 3 months at four sites in India, with each participant completing a maximum of four surveys. Participants were categorized as non-frail (0-5 points), vulnerable (6-7 points), and frail (≥8 points) based on EFS score.

In Zambia, cholera has been a persistent public health concern for decades, mainly attributed to inadequate sanitation and restricted access to clean water in some parts of the country. The literature was collected from PubMed, Google Scholar, and public health organization websites, focusing on cholera outbreaks in Zambia since 2000. Key search terms included 'cholera prevention' and 'Zambia outbreaks.

In the current study, the analytical sensitivity, analytical specificity, reproducibility, anti-interferences ability, and clinical performance of the QIAstat-Dx Gastrointestinal Panel (GIP) system were evaluated using pooled stool samples. Results showed that the pooled sample test detected the selected ten targets exclusively, with no cross reaction with any other targets of common enteropathogens. The analytical sensitivity of the pooled sample test on QIAstat-Dx GIP system was 10 CFU/ml for Shigella spp.
