Abstract:

Background: Drug-resistant tuberculosis (DR-TB) poses a significant challenge to global TB control efforts, particularly in low- and middle-income countries (LMICs) where diagnostic resources are limited, thereby widening treatment gap. This has increased morbidity and mortality due to TB in Sub-Saharan Africa. We sought to evaluate the role of clinical diagnosis in identifying DR-TB in pulmonary TB cases missed by the sputum GeneXpert MTB/RIF assay in Ekiti State, Nigeria.

Abstract:

Background: Aquaculture environments are increasingly recognized as reservoirs for antimicrobial-resistant bacteria due to the routine use of antibiotics such as tetracyclines. Members of the family Enterobacteriaceae readily acquire and disseminate resistance determinants, posing risks to food safety and public health. In Nigeria, molecular data on tetracycline resistance in aquaculture systems remain limited. This study investigated the occurrence and molecular basis of tetracycline resistance among Enterobacteriaceae isolated from earthen catfish ponds in Akure, Nigeria.    Continue reading “Molecular detection of tetracycline resistance genes in an emerging Enterobacteriaceae isolate from earthen catfish ponds in Akure, Nigeria”

Abstract:

 Background: Hepatitis E virus (HEV) is a zoonotic pathogen with significant public health implications, particularly among pig handlers who are at increased risk due to occupational exposure. Despite the growing pig farming industry in Enugu State, Nigeria, awareness and preventive practices related to HEV remain poorly understood. This study assessed the knowledge and preventive measures of HEV among pig handlers in Enugu State, identifying key demographic factors influencing awareness and hygiene practices.

Abstract:

Background: Klebsiella species are significant pathogens responsible for various healthcare-associated infections. Despite the existence of several mechanisms of resistance against high priority antibiotics such as carbapenems, the production of carbapenemases remains the most important mechanism of resistance among Klebsiella spp. The aim of this study was to determine the prevalence of carbapenemase-production among Klebsiella spp isolated from clinical specimens at the University College Hospital (UCH) Ibadan, Nigeria.

Abstract:
Background: Antibiotics are significant for improving the health and productivity of chickens, but overuse and misuse of antibiotics have led to the development of antimicrobial resistance (AMR), which has resulted in ineffective treatment of infectious diseases with associated mortality in chicken and potential spread of AMR pathogens to humans. The objective of the study was to evaluate the AMR profiles of Enterobacteriaceae from faecal samples of laying chicken in Ibadan, southwestern Nigeria.
