BIOTYPING OF MULTIDRUG RESISTANT CAMPYLOBACTER JEJUNI FROM POULTRY AND HUMANS IN NORTHERN REGION OF GHANA

Thermophilic Campylobacters are zoonotic bacteria which are universally famous for causing enteritis in humans. They are normally found as commensals in the digestive tract of food animals with poultry being a major reservoir of the pathogenic species. This study highlighted the presence of Campylobacter in poultry (commercial and domestic) and humans (patients and asymptomatic individuals) and characterized strains by biotyping and susceptibility test in the Northern region of Ghana where an...

Hidden diversity of eukaryotic plankton in the soda lake Nakuru, Kenya, during a phase of low salinity revealed by a SSU rRNA gene clone library

Abstract A SSU rRNA gene clone library was constructed to establish the diversity of eukaryotic plankton in the African soda lake Nakuru during a phase of low salinity (9.7 ppt = hyposaline). Normally, the lake is mesosaline (up to 50 ppt) and its phytoplankton is dominated by few species of cyanobacteria, in particular Arthrospira fusiformis, which is the main food resource of Lesser Flamingos. Our study recovered a unique phytoplankton species composition characterized by a high diversity ...

Exposure to Salinity and Light Spectra Regulates Glucosinolates, Phenolics, and Antioxidant Capacity of Brassica carinata L. Microgreens

Abstract: The effect of salt treatment on Brassica carinata (BC) microgreens grown under different light wavelengths on glucosinolates (GLs) and phenolic compounds were evaluated. Quantifiable GLs were identified using ultra-high performance-quadrupole time of flight mass spectrometry. Extracts’ ability to activate antioxidant enzymes (superoxide dismutase (SOD) and catalase (CAT)) was evaluated on human colorectal carcinoma cells (HCT116). Furthermore, BC compounds’ ability to activate ...

Multi-source spatial data-based invasion risk modeling of striga (Striga asiatica) in Zimbabwe.

Abstract: Monitoring of destructive invasive weeds such as those from the genus Striga requires accurate, near real-time predictions and integrated assessment techniques to enable better surveillance and consistent assessment initiatives. Thus, in this study, we predicted the potential ecological niche of Striga (Striga asiatica) weed in Zimbabwe, to identify and understand its propagation and map potentially vulnerable cropping areas. Vegetation phenology from remote sensing, bioclimatic an...

Droplet Actuation Platform for Chemical Sensors

An open microfluidic system has been developed to dispense and manipulate individual droplets on plastic sheets. Superhydrophobic material is applied to the surface of obtainable plastic sheets by spraying, then hydrophilic symbols are printed with an inkjet printer. The plastic sheets are connected to a two-axis tilting platform driven by stepper motors, which produces mechanical agitation enabling droplet transport. The system has been demonstrated to carry out various droplet operations, s...

Antimicrobial Resistance Pattern of Coagulase-negative Staphylococci isolates from Medical Students of Some Nigerian Teaching Hospitals

Abstract The antimicrobial resistance or otherwise of Coagulase-negative Staphylococci (CoNS) isolates from medical students of some South Eastern Nigerian Universities were determined. Swab samples were obtained from the students and were cultured for CoNS using standard microbiological methods. Isolates obtained were assayed for antibiotic resistance using disc diffusion method. MecA and blaZ genes on 533bp and 510bp respectively, of the isolates were amplify using the Polymerase Chain Reac...

ENHANCEMENT OF METHANE PRODUCTION BY CODIGESTION OF KERATIN AND CELLULOSIC FEEDSTOCKS AT MESOPHILIC AND THERMOPHILIC CONDITIONS USING MICROBIAL CONSORTIA

ABSTRACTNigeria has energy crisis, hence, there is urgent need to diversify the country’s energy resources towards renewable alternatives for economic and social transformation. Biogas generated from the anaerobic digestion of local biomass resources, will increase national energy security as well as reduce dependence on fossil fuels. Optimization of methane production by codigestion of poultry feather and sawdust using microbial consortia were investigated. The results of the molecular ide...

ISOLATION AND CHARACTERIZATION OF MICROORGANISMS ASSOCIATED WITH BIOREMEDIATION OF HYDOCARBON POLLUTED SITES

Abstract:  The negative impacts of hydrocarbon pollutants on our environments and economic resources cannot be overemphasized. The need to harness the bioremediation potentials of microorganisms associated with hydrocarbon pollution becomes very imperative in order to mitigate the environmental impacts of petroleum hydrocarbons in our environments. The molecular identification of the microorganisms isolated from four automobile workshops at Ugbene 2 Abakpa Nike, Enugu, Nigeria based on 1...

PRODUCTION OF COMPOSITE YOGHURT FROM BLEND OF SOY MILK AND COW MILK USING MIXED LACTIC STARTER CULTURES ISOLATED FROM AQUARAPHA YOGHURT

ABSTRACTThe need to improve our vegetable protein consumption in order to reduce the incidence of protein deficiency diseases cannot be over-emphasized. This research was premised on evaluating the appropriate levels of substitution of cow milk with soya milk to produce composite yoghurt. Eight hundred (800) grams of soya bean seeds after sorting out foreign materials and washing were usedto produce 4.0 liters of soya milk (20% total solids). Cow milk (20% TS) was blended with soya milk in th...

Keywords: Environment, Annual rate, Global crisis, Foreign investors, Epidemiology, Psychology. Introduction The outbreak of Coronavirus Disease (COVID-19) has been declared a Publi...

Determination of Minimum Data Set for Vegetable Fields under Biofertilizer-fortified Compost Farming in Southwestern Nigeria

This  study  discovered  that  infiltration  rate,  bulk  density, pH  and  available  phosphorous  were  the  most  sensitive  soil properties  for  use  as  MDS  indicators for vegetable fields at south western of Nigeria. The    study    also    revealed    that    both    the  MDS indicators  and  SQI  value  obtained  were  influenced  by biofertilzer-fortified  compost  application and would  serve  as vital  instrument for evaluating soil fe...
