Evaluation of cypermethrin insecticides on the growth of some selected soil bacteria isolated from Makurdi, Middle Belt, Nigeria
In the present investigation, a total of 30 soil samples were collected from five different sites in Makurdi metropolis to investigate the effect of cypermethrin on some soil bacteria. Physicochemical properties of the soil samples from various sites were determined using standard procedures. Some selected soil bacteria such as Escherichia coli, Klebsiella spp., Bacillus spp., Staphylococcus spp. and Proteus spp. were...

A study of bacterial pathogens associated with diarrhoea in children under 2 years in Ile-Ife, Nigeria
Diarrhoea, a major contributor to high mortality in children may be caused by an array of bacterial, viral or parasitic pathogens acting individually or synergistically. This study identified the bacterial pathogens associated with diarrhoea in children aged 0-24 months, established the frequency of diarrhoea caused by each pathogen encountered in diarrhoea and determined the antibiotic resistance pattern of the...

Mycorrhizal activity as a quality indicator in the use of mining slag as soil conditioner
The main residue of iron and nickel mining is slag, a solid residue of low solubility and rich in magnesium silicate. A residue with potential use as a soil conditioner, however, it is still necessary to investigate whether its use brings impacts to the environment. Microorganisms are extremely sensitive to environmental changes, changes that can be used as environmental quality indicators. Among the organisms that act...

Identification of recombinants of hepatitis B virus genotypes C from Hong Kong China
Hepatitis B virus (HBV) infections severely threaten the health of the human being. Frequent recombination of HBV within or between genotypes was reported to favor the viral evolution and adaption and the recombination may cause more severe clinical symptoms. In the study, we collected genotype C HBV from five Asian countries and detected their possible recombination events by bioinformatic analysis. There are two main...

Molecular identification of genotypes of Hepatitis B virus in Borno State, Nigeria
Hepatitis is a significant disease of the liver caused by different genotypes of hepatitis B virus. Neonates delivered of HBsAg and HBeAg positive mothers are most susceptible. The sequelae of infection and prognosis vary with the age of patient infected and the genotype (A-J) of the virus involved. These genotypes have 7.5 to 8% difference in their genomic sequences. This study was aimed at identifying the genotypes...

Occurrence of virulent and antibiotic resistant Staphylococcus species in ready-to-eat Rhynchophorus phoenicis and Archachatina marginata vended along the Port Harcourt-Bayelsa route
This study was aimed at determining the occurrence of Staphylococcus species in ready-to-eat (RTE) Rhynchophorus phoenicis (edible larvae) and Archachatina marginata (land snail) vended along Port Harcourt-Bayelsa route. Eighty samples from four locations were analysed employing standard techniques for proximate and microbiological analyses; virulence determination and antibiotic susceptibility. Data were statistically...
