this study is aimed at assessing the in-vitro effect of Aframomum daniellii seed extract, Aloe vera gel, Gongronema Latifolium leaf extract, Monodora myristica seed extract and honey on Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae and Candida albicans. Agar well diffusion method was used for the susceptibility test. The plates were incubated at 37 oC for 24 h. Extracts and diameter zones of inhibition were measured. All test organisms were susceptible to honey and Aloe vera gel, and a combination of both honey and Aloe vera gel.

This study assessed heavy metals (HMs) contamination in road dust using geochemical indices and their potential risks from an urban environment in Delta State, Nigeria. Fifteen road dust samples were sampled, digested in aqua regia and their HMs concentrations determined using atomic absorption spectrometry.

Tomato as vegetable and regarded as protective food is a very significant food crop globally. In this study, lycopene present in tomato and known for its anti-oxidative ability was correlated with fruit yield. Three varieties of tomato were selected and their growth rates were compared by measuring the length (cm) of stem from the day of transplanting till maturity (at flowering), on weekly basis. The three tomato varieties identified as Igb1/9/21, Igb2/9/21 and Igb3/9/21 were not significantly different in their growth.

The efficacy of methanol leaf extract of Jatropha curcas was investigated through in-vitro assay against Trypanosoma brucei-brucei in 96 well micro-titer plates. Maceration method was used to obtain the leaf extract using absolute methanol.

This study was carried out to evaluate the hypoglycemic, hematologic and hypolipidemic potential of berry oil in alloxan-induced adult Wistar rat. Five groups of Wistar rats (4 rats per group) Group 1 served as “Normal control” rats and received normal rat pellets and water. Diabetes mellitus was induced in Groups 2, 3, 4, and 5 by intraperitoneal injection of alloxan (160 mg/kg). Group 3 rats were treated with glibenclamide (5 mg/kg body weight), groups 4 and 5 received 500 mg/kg and 1000 mg/kg body weight of Berry oil daily respectively for 21 days via oral gavage.

The aim of this study was to evaluate the effect of poultry manure on the growth of Amaranthus caudatus with a view to establishing the optimum poultry manure treatment for its growth. The study was carried out between the months of February and May 2020, in a portion beside the botanical garden in the University of Benin, consisted of three (03) treatments namely PM1 (10%), PM2 (20 %), and PM3 (30 %) with poultry manure and control (PM0) in a randomized complete block design (RCBD) and replicated three times.

This study was carried out in the undergraduate project plot of the department of Plant Biology and Biotechnology, University of Benin from March to July 2020, to determine the impact of lead contamination on okra plant. A field experiment was conducted using 4 levels of Pb pollution namely 25, 50, 75, 100 mg/kg and control. Each bag containing 5 kg of air dried sandy loam soil was arranged in a completely randomized design (CRD) with three replicates. Five (05) seeds were sown in each bag. All bags were watered regularly. Plants were thinned down to one per bag after a week of emergence.

Phytochemical and gas chromatography and mass spectrometry (GCMS) analysis of the ethanolic extract of Uvaria ovata (Uo) roots was carried out. Phytochemical analysis showed high amounts of alkaloids, tannins and flavonoids, moderate amounts of saponins, terpenes and cardiac glycosides, while steroids and phenols were found in little quantities. Gas chromatography and mass spectrometry analysis revealed the presence of eleven compounds, of which D-Streptamine and Cystine were prominent.

Therapeutic plants have kept on drawing in consideration worldwide in the quest for powerful antimicrobial drugs that can battle resistant pathogens that have rendered numerous conventional medications out of date in the treatment of diseases. As such this study was carried out to evaluate the ethnobotanical survey of medicinal plants used for oral pathogens among Esan tribe in Esan West Local Government Area of Edo State. A total of four medicinal plants were collected and identified as follows: Harungana madagascariensis, Jatropha curcas, Aframomum melegueta and Plumbago zeylanica.

Staphylococcus aureus is one of the most significant pathogens causing nosocomial infections. Twelve (12) methicilllin resistant Staphylococcus aureus (MRSA) strains obtained from clinical samples in Abia State, Nigeria was subjected to DNA fingerprinting by Random Amplified Polymorphic DNA (RAPD) analysis to examine their genotypic polymorphism and subsequently determine the degree of genetic relatedness among the various isolates. DNA extraction was carried out by boiling method and quantified using nanodrop1000 spectrophotometer.
