Identifying the dissemination patterns and impacts of a virus of economic or health importance during a pandemic is crucial, as it informs the public on policies for containment in order to reduce the spread of the virus. In this study, we integrated genomic and travel data to investigate the emergence and spread of the SARS-CoV-2 B.1.1.318 and B.1...

The three foremost medically important mosquito species of public health importance belong to the genera Anopheles, Aedes, and Culex. The Anopheles mosquito is the most important in the transmission of human malaria, while members of the genera Culex and Aedes are more important in the transmission of arboviruses. Reducing the number of competent v...

Three selected chicken abattoirs and two retail locations were studied to determine the frequency of occurrence and profile for Shiga toxin-producing Escherichia coli (STEC) strains present in abattoirs and retail (frozen) chicken carcasses in Osun state, Nigeria. Samples were plated on Eosin Methylene Blue agar for the presence of E. coli. Further...

Investment in Africa over the past year with regards to SARS-CoV-2 genotyping has led to a massive increase in the number of sequences, exceeding 100,000 genomes generated to track the pandemic on the continent. Our results show an increase in the number of African countries able to sequence within their own borders, coupled with a decrease in sequ...

The spate of health challenges via the ingestion of radionuclides is still of concern especially in regions that have no clear documentation of background of radioactive sources. The present study evaluated the activity concentrations of naturally occurring radioactive nuclides in plants and their corresponding soil collected at Ibeshe and Covenant...

The progression of the SARS-CoV-2 pandemic in Africa has so far been heterogeneous and the full impact is not yet well understood. Here, we describe the genomic epidemiology using a dataset of 8746 genomes from 33 African countries and two overseas territories. We show that the epidemics in most countries were initiated by importations predomina...

Recent reports on finding Wolbachia-strain infections in field mosquito species in some West African countries and the potential for developing these as disease vector biocontrol tools have prompted a search for Wolbachia in mosquitoes within the study area. Using a completely randomised design, mosquito traps were set at different locations in a r...

Aim: To explore perceptions, attitudes and hand washing practices in relation to the effectiveness of hand sanitizers in controlling enteropathogens amongst residents of a Nigerian University with the purpose of creating awareness on the importance of hand hygiene to control the spread of communicable diseases. Study Design: A simple random cluster...

Aim: In order to ensure the accurate taxonomic identification of the lactic acid organisms that were previously isolated from spontaneously fermented yam for safety assessment and quality assurance purposes, phenotypic and genetic identification data were compared. Study Design: Using the purposive sampling method, four microorganisms were characte...

Aim: The present work was aimed at ensuring the accurate taxonomic identification of the fermentation organisms previously isolated from spontaneously fermented cassava for the purpose of safety assessment and quality assurance. Study Design: Purposive sampling method was used as all the five isolated organisms (from the previous study); 2 bacteria...

Groundnut (Arachis hypogea) and its popular derivative snack-product, kulikuli are particularly prone to contamination by a wide variety of toxigenic microorganisms due to its high nutritive content. Peanuts are rich in calories and contain many nutrients, minerals, antioxidants, and vitamins that are essential for optimum health. Samples were coll...

Hand washing is known to be an important preventive strategy and a major step in infection control. However, compliance is low in most communities. The present work investigated the relationship between the levels of compliance to hand washing and related this to the occurrence of infectious bacteria in the test population. A questionnaire which co...

Objectives: Three operational types of abattoir, batch, slaughter and line abattoirs with their effluents (wastewater) were investigated for bacteriological quality in Lagos and Ogun states of Nigeria. The present study is a surveillance work to assess the housekeeping practices and the environmental impact of the three major abattoir types in Nige...

Musa paradisiacal (plantain) is among the major tropical staple foods. This study was designed to determine the proximate, mineral, fat soluble vitamins and acrylamide constituents of unripe plantain fried with three different oils (canola oil, soya oil and vegetable oil) and unripe plantain oven dried. The vitamins and acrylamide determination wer...

The aim of this study is to partially purify and characterize the cellulase extracted from the snail haemolymph of the African giant land snail of the species, Archachatina marginata. The protein concentration of the haemolymph was found to be 168 mg mLG 1 and the specific activity of the crude cellulase was found to be 0.007 U mgG 1 protein using...

In spite of its socio-economic and cultural importance to silk production, not much work has been done on Bombyx mori and silk farming in Nigeria. Of particular interest to this study is bacterial flacherie which is probably the most serious disease of Bombyx silkworm. Using a completely randomized block design, moribund (manifesting symptoms of fl...

When JH II, III or methoprene was applied in the nymphal stages to two different strains of the brown planthopper which were selected to produce long (macropterous) or short (brachypterous) wing forms, no effect was observed on the molting profile or metamorphosis. Brachypterization of a majority of the presumptive macropters was, however, observed...
