ABSTRACT From 2007 to 2011 HIV-positive pregnant women in Ghana, were given a combination of Zidovudine and Lamivudine as prophylaxis during pregnancy and a single dose of Nevirapine upon the onset of labour towards the prevention of mother to child transmission (PMTCT) of HIV. Since these women were subsequently given the same antiretrovirals (ARVs) to manage their HIV infection, there was, therefore, the need to determine the HIV-1 drug resistance profiles in such patients in Ghana. This s...
ABSTRACT The resurgence of lymphatic filariasis (LF) infection after several rounds of Mass Drug Administration (MDA) has been the main reason behind constant monitoring of treatment. The MDA is designed to interrupt transmission by reducing microfilaraemia in a community to a threshold that local vectors may not be able to pick up microfilariae (MF) during a blood meal. The current study has been carried out to determine whether transmission had actually been interrupted following stoppage o...
ABSTRACT Molecular studies of ESβL-producing bacteria isolated from clinical samples was determined as well as the effects of medicinal plants on the isolates. The study was conducted from September 2013 to September 2015. A total of 480 bacterial isolates (250 from urine, 110 from wound swab & 120 from HVS & US) were used. The knowledge, attitude and practices (KAP) of health workers in Imo State towards multiple antibiotic resistant bacterial isolates and extended spectrum beta-lacta...
ABSTRACT Background: Wound infections mostly caused by Pseudomonas are on the increase in hospitals in Ghana. Most of these infected wounds are very difficult to treat with available antibiotics. This failure of treatment has resulted in increased need for healthcare, undue financial burden on both hospitals and patients and finally death of many of these patients. This has become a source of worry for both patients and healthcare providers in Ghana. General Aim: The main aim of this study w...
Abstract Mushrooms are considered as one of the notable functional foods for human consumption that have been cultivated and gathered for hundreds of years. The usage of mushrooms has expanded to a wide extent not only as food but also in the area of pharmaceuticals and nutraceuticals. In particular, mushrooms have been appreciated and consumed for both their nutritional value and medicinal properties. Bioactive molecules, particularly polysaccharides (PS) from mushrooms have been the subject...
Abstract As an initial step towards characterisation of the molecular processes that define the phenotype of the mycobacterial stationary phase, the effect of growth phase of Mycobacterium smegmatis on total protein synthesis and on the heat shock response was investigated. De novo protein synthesis was monitored by labelling with 35 [S]methionine and the protein expression profiles analysed using one- and/two-dimensional polyacrylamide gel electrophoresis , autoradiography , and/or immunoblo...
ABSTRACT Methicillin-resistant staphylococcus (MRS) infections are of global concern in healthcare institutions and community settings with significant morbidity and mortality due to multidrug resistance challenges. In Nigeria, most methicillin resistance detection was based on phenotypic method with scanty reports on molecular characterisation of MRS. In this study, molecular techniques were used to determine the presence of methicillin resistant gene (mecA) with its associated resistance de...

A B S T R A C T The physiological activities of Bacillus species that ferment African locust bean (Parkia biqlobosa (Jacq.) BenthJ to produce ' iru1 were investigated. The strains studied belong to the B. subtillis group and Were designated BS1 , BS2, BS3, BLl, BL2, BL4 and BP2. These seven strains showed significant differences (at c* = 0.05) in gtowth and extracellular proteinases production. The following (defecending) Order was obtained for the growth of the organisms in liquid medium: BS...
ABSTRACT Fish farming enterprise has increased in recent times due to public demand for fish protein. However, rising costs of fish feed ingredients have greatly reduced the profit margin of local fish farmers. Cheap, readily available and locally sourced ingredients may be better substitutes to the costly fish feeds. The aim of this study was to evaluate the performance of fermented Palm Kernel Cake (PKC) and Rice Bran (RB) as substitutes in the diet of Clarias gariepinus. Fungi were isolate...
ABSTRACT Tylosema esculentum is a nutritious drought avoiding plant endemic to the Kalahari Desert. Our study assessed the density, diversity and distribution of endophytic microbial community structures associated with leaves, stems and tuberous roots of T. esculentum in Eastern Namibia. Culture-dependent and PCR-based 454 pyrosequencing methods were used. ANOVA with pairwise comparison revealed a significant difference in bacterial density between below and above ground. Endophytic bacteri...
Abstract Namibia is among the driest countries in the world, and with the current drought that the country is experiencing, there is a greater need to provide drinking water not only to Windhoek, but the greater Nation at large. The Gammams Wastewater Treatment Plant, which is responsible for treating domestic and some industrial wastewater, regularly experiences toxic pluses that result in the inhibition of nitrification in the activated sludge process, leading to poor removal of ammonia. T...
ABSTRACT Most African foods used in weaning are usually cereal-based gruels fermented by Lactic Acid Bacteria (LAB). The food mainly supplies carbohydrate; excessive intake of which might cause malnutrition in growing children. Minimum dietary requirements of a child could be met through fortification with protein-rich supplements. Soybean is rich in dietary protein but contains some antinutritional factors and raffinose, an oligosaccharide responsible for gas formation, bloating and flatulen...
Abstract Background: The ability of the host immune system to efficiently clear Plasmodium falciparum parasites during a malaria infection depends on the type of immune response mounted by the host. Study design: In a cross-sectional study, we investigated the cellular-and antibody responses in individuals with P. falciparum infection, in an attempt to identify immunological signs indicative of the development of natural immunity against malaria in Ibadan, Nigeria. Levels of IL-10, IL-12(p70)...
ABSTRACT While street vended ready-to-eat meats provide a source of readily available and nutritious meals for the consumers, there is a concern for their safety and microbiological quality. The prevalence of E. coli, Salmonella, Shigella, L. monocytogenes, S. aureus and Enterobacteriaceae was assessed in a total of 96 street vended ready-to-eat meat samples collected from Windhoek locations, namely, Katutura, Prosperita and Dorado Park. Selective media was used to assess aerobic plate count...
