Abstract:

The increasing threat of antimicrobial resistance (AMR) in Africa, coupled with limited access to advanced antibiotics and high rates of bacterial infections poses serious public health challenge. Bacteriophages, viruses that target and destroy bacteria, present a promising alternative or complementary therapy to traditional antibiotics. Phage therapy leverages its unique ability to target specific bacterial strains without affecting the host beneficial microbiota. It is an effective tool against multi-drug-resistant (MDR) microbial pathogens, particularly in resource-limited settings. This narrative review explores the potentials of phage therapy in Africa, highlighting its advantages, such as specificity, minimal side effects, and cost-effectiveness, alongside its capability to tackle biofilm-associated and AMR infections. It discusses current research and collaborations, including case studies from Nigeria, Benin, and South Africa that demonstrate the efficacy of phage therapy against bacterial pathogens such as Escherichia coli, Acinetobacter baumannii and Klebsiella pneumoniae. Furthermore, it discusses the challenges to phage therapy implementation such as regulatory hurdles, public skepticism, and infrastructure limitations, while emphasizing the importance of developing local production and awareness campaigns. The review concludes by recommending the integration of phage therapy into Africa healthcare strategies to address AMR. Through strategic partnerships, education and regulatory frameworks, phage therapy could become a transformative solution, particularly for neglected diseases and infections common in low-resource settings. As Africa seeks innovative approaches to its growing AMR crisis, phage therapy stands out as a viable and adaptable option.

Abstract:  

Background: Antimicrobial stewardship (AMS) is one of the main strategies to stem the global tide of antimicrobial resistance (AMR). While developed nations have successfully implemented antimicrobial stewardship programmes, such initiatives remain underdeveloped in many Nigerian healthcare institutions. This is a report of a project to improve the AMS programme at the Lagos University Teaching Hospital (LUTH), Nigeria, by strengthening the antimicrobial stewardship committee (AMSC) and antimicrobial stewardship team (AMST) of the hospital.

Abstract:

Background: Antibiograms and antibiotic guidelines are important tools for appropriate prescribing practices in combating the antimicrobial resistance (AMR) challenge. They serve as a prelude to an evidence-based Antimicrobial Stewardship (AMS) program, which is necessary for better Infection Prevention and Control (IPC) activities, especially in low-resource settings like Nigeria. This study determined the bacterial profile and antibiogram of clinical isolates in a tertiary healthcare facility in Gombe, northeastern Nigeria.

Abstract:

 Background: Lassa fever (LF) is a zoonotic acute viral hemorrhagic disease caused by the Lassa virus (LV). It has a high case fatality rate of about 5,000 deaths in humans from 300,000-500,000 cases each year globally. The high mortality rate from Lassa fever has been associated with abnormal liver enzyme production due to LV infiltration of the liver. However, data are sparse on the different enzymes and their proportions associated with LF. This study aims to evaluate the effect of LF on the levels of selected liver enzymes.

Abstract:

Background: The pervasive presence of filamentous fungi in poultry farming environments has a profound impact on the bird health, leading to reduced growth rates, increased mortality, and decreased egg production. The objective of this study was to use an avian model to determine the pathogenicity of some filamentous fungal isolates from litter, feed, and fecal samples on day-old birds.  Continue reading “Pathogenicity of filamentous fungi isolated from poultry farms on gastrointestinal system of day-old chicks in Anambra State, Nigeria”

Abstract:

 Background: Salmonellosis persists in Lagos, Nigeria, despite interventions. This study investigated antimicrobial resistance patterns of Salmonella species from clinical, food, and environmental samples in Lagos.    Methodology: From June to December 2018, 276 samples (86 blood, 80 stool, 40 hospital effluents, and 70 food) were collected for microbiological analysis. Clinical samples (blood and stool) were collected from patients in General Hospital Igando and Lagos State University Teaching Hospital Ikeja. Food samples were collected from food vendors in the urban periphery of Lagos State, and hospital effluents were collected from Gbagada General Hospital and Ojo Health Centre. The samples were processed using standard microbiological procedures.

Antimicrobial susceptibility of isolated bacteria was done using the Kirby-Bauer disk diffusion method. Continue reading “Antimicrobial susceptibility pattern of Salmonella isolates from clinical, environmental and food sources in Lagos, Nigeria”

Bacteriological quality of Datura stramonium cocktail (‘gegemu’) and antimicrobial susceptibility of isolated bacterial pathogens

*1Onipede, J. A., 2Morka, E., 1Adeleye, O. R., and 3Onipede, O. M.

Abstract:
Background: Datura stramonium, commonly known as Jimson weed, is widely recognized in traditional medicine, and is a key ingredient in various herbal concoctions. Aside from the well-known herbal formulation, a cocktail made from Datura stramonium, known locally as ‘gegemu’, has become increasingly popular among students in our environment, raising concerns about its microbial quality. The fact that this cocktail is not commercially available raises the possibility of contamination by pathogenic microorganisms during preparation or storage, posing significant health risk. The objective of this study was to assess the microbial quality of this cocktail drink and determine the antimicrobial susceptibility of the bacteria isolates.
