Methods: A cross-sectional study was conducted to investigate the prevalence of coinfection of malaria and bacterial bloodstream infections among 232 children under 13 years who reported to three healthcare facilities in Accra and Dodowa ...

PHENOTYPIC CHARACTERIZATION OF HOST-PATHOGEN INTERACTION IN Mycobacterium africanum

Abstract Background: Mycobacterium africanum (MAF) and Mycobacterium tuberculosis sensu strico (MTBss) are two members of a closely related bacterial species of Mycobacterium tuberculosis complex (MTBC) that causes tuberculosis (TB) in humans. However MAF is known to cause up to 50% of human pulmonary TB in West Africa only. MAF has been subdivided into MAF West African 1 (MAF1) (Lineage 5) and MAF West African 2 (MAF2) (Lineage 6), as two distinct phylogenetical lineages within MTBC. Subsequ...

MOLECULAR CHARACTERIZATION OF PREVIOUSLY NON-TYPEABLE ROTAVIRUS STRAINS IN GHANA

ABSTRACT Background Rotavirus is associated with severe infantile diarrhoea requiring hospitalization. In order to control severe disease caused by rotavirus infection, vaccination is considered an essential strategy. Currently, two rotavirus vaccines (Rotarix™ and RotaTeq™) have been included in the Expanded Program on Immunization of most African countries to help reduce the high disease indections. Ghana has over the past 20 years been involved in the surveillance of rotavirus diseases...

Occurence, Civersity and Antimicrobial Susceptibility of Listeria Species From Retail Raw Beef and Goat Meat in Port Harcourt, Nigeria

ABSTRACT Listeriosis has emerged as a disease of public health importance because of its clinical severity, high fatality and challenges to its control including resistance to antibiotics. Outbreaks reported in developing countries including Nigeria were associated with consumption of meat and meat products. However, previous work on Listeria in Nigeria focused on environmental samples. Hence, the need to ascertain the presence of Listeria in meat and their response to antimicrobial agents. ...

ANTIBACTERIAL ACTIVITIES OF THREE MEDICINAL PLANTS ON ORGANISMS ASSOCIATED WITH DENTAL PLAQUE

ABSTRACT The antimicrobial properties of plants have shown promise for development of new drugs which might aid to overcome the increasing challenge of resistance and also the toxicity of the currently available antibiotics. Hence, the aim of the study was to investigate the antibacterial activities of Sida acuta, Anthocleista nobilis, and Zanthozylum leprieurii on clinical isolates of Streptococcus mutans and Streptococcus sanguis and two reference strains: Streptococcus mutans (ATCC 700610)...

Entamoeba histolytica infection in children in Accra: prevalence and risk factors

ABSTRACT Background: Entamoeba histolytica causes amoebiasis in humans which is a major cause of morbidity and mortality in children in developing countries like Ghana where there are problems with sanitation. Studies conducted in Ghana have not placed much emphasis on the prevalence of this infection in both symptomatic and asymptomatic children in Accra. Thus, the aim of this study was to determine the prevalence of Entamoeba histolytica among children in Accra, and to identify some risk fa...

THE POTENTIAL ROLE OF NOCTURNAL BITING INSECTS IN THE TRANSMISSION OF MYCOBACTERIUM ULCERANS IN THE AKUAPEM-SOUTH DISTRICT

ABSTRACT Several hypotheses have been made about the possible mode of transmission of Mycobacterium ulcerans (M. ulcerans) and one of these is the role of insects as possible vectors. Although studies have been conducted extensively on aquatic insects and mosquitoes, limited work has been done on the prevalence of M. ulcerans in other insects. This study investigated the potential role of nocturnal biting insects as vectors of M. ulcerans. Nocturnal insects were sampled from Buruli Ulcer ende...
