The carriage rate of Hepatitis-B surface antigen (HBsAg) in an urban community in Jos, the Plateau State capital, was studied to obtain the pattern of Hepatitis-beta virus (HBV) spread within the community. HBsAg screening was performed on a consecutive sample of 524 apparently healthy individuals (293 males and 231 females) aged 15-65 years who voluntarily turned up for the survey. Fifty-four (10.3%) were HBsAg positive by ELISA. The carriage rate in females 30/231 (13.0%) was significantly higher than in the males 24/293 (8.2%) (p<0.05). In relation to age, 14/144 (9.7%) were aged <20 years, 11/121 (9.1%) were 21-30 years, 7/115 (6.1%) were 31-40 years, 14/89 (15.7%) were 41-50 years, 2/27 (7.4%) were 51-60 years and 6/28 (21.4%) were >61 years. In relation to marital status, carriage rate was highest among the divorced/widowed group (12.5%) followed by the married group (10.6%). Carriage rates in relation to occupation showed that infection was highest among traders (13.7%) and students (13.2%). The survey therefore confirms the endemicity of HBV infection in Jos and describes the groups that are at risk. This calls for health education of the general population on preventive measures to check the spread of the virus in the community.

An evaluation of clonal relationship by PFGE method in Acinetobacter baumannii isolates, examining integron presence and antibiotic resistance.

Introduction: This study aims to investigate the presence of class 1, 2, and 3 integrons in Acinetobacter baumannii isolates, evaluate the relationship between integrons and antibiotic resistance and determine the clonal relationship between isolates by PFGE method.
Methodology: A total of 188 A. baumannii strains between February 2020 and March 2023 were included in the study.
Genetic and genomic variation among microbial strains can dramatically influence their phenotypes and environmental impact, including on human health. However, inferential methods for quantifying these differences have been lacking. Strain-level metagenomic profiling data has several features that make traditional statistical methods challenging to use, including high dimensionality, extreme variation among samples, and complex phylogenetic relatedness.

Cases of antibiotic-resistant () infections are becoming increasingly frequent and represent a major threat to our ability to treat cancer patients. The emergence of antimicrobial resistance threatens the treatment of infections. In this study, the antimicrobial profiles, virulent genes, and the frequency of extended-spectrum beta-lactamase (ESBL) gene carriage in fecal isolates from cancer patients at the Laquintinie Hospital in Douala (Cameroon) were determined.

Background: The prevalence of meningococcal carriage and serogroup distribution is crucial for assessing the epidemiology of invasive meningococcal disease, forecasting outbreaks and formulating potential immunization strategies. Following the meningococcal carriage studies conducted in Turkey in 2016 and 2018, we planned to re-evaluate meningococcal carriage in children, adolescents and young adults during the COVID-19 pandemic period.
Methods: In the MENINGO-CARR-3 study, we collected nasopharyngeal samples from 1585 participants 0-24 years of age, across 9 different centers in Turkey.
Streptococcus pyogenes carriage rate, associated factors and antimicrobial susceptibility profiles among urban and rural schoolchildren at Gondar city, Northwest Ethiopia.

Streptococcus pyogenes remains one of the top ten causes of mortality from infectious diseases. Children in low-income nations have high carrier rates of Streptococcus pyogenes, which can serve as a source of infections, including simple superficial infections that may lead to invasive and post-streptococcal diseases, particularly among schoolchildren. This study aimed to assess the prevalence of Streptococcus pyogenes, associated factors, and antimicrobial susceptibility profiles among urban and rural public schoolchildren in Gondar City, Northwest Ethiopia.
