Isolation, Identification And Characterization Of Microbial Contaminants In Selected Biosafety Laboratories In Kenya

ABSTRACTMicrobial contamination in laboratories and hospitals is becoming serious problem worldwide and characterization of such contaminants offer hope for treating some hospital and laboratory acquired infections (LAI). Microbial contaminants on benches, floors, media and in equipment can be influenced by temperature, humidity, nutrient media used in the laboratories as well as storage conditions of the media. Therefore there is need to determine the microbial sources, isolate and identify ...

Associations Between Sdf-1 Alpha Polymorphisms And Malarial Outcomes In Children At Siaya County Referal Hospital, Western Kenya

ABSTRACTIn high Plasmodium transmission regions, malaria caused by Plasmodium falciparum is the leading cause of malaria-related morbidity and mortality among children under the age of 5 years. Severe malaria anaemia (SMA) is the most common cause of malaria burden in holoendemic P. falciparum transmission regions such. Although the mechanisms underlying development of SMA are poorly understood, direct and indirect lysis of erythrocytes, suppression of erythropoiesis, erythrophagocytosis, dys...

Evaluation Of Biological Activity Of Alkaloids And Flavanoids In Zanthoxylum Gilletii (De Wild Waterman) Extracts From Different Geographical Regions In Kenya

ABSTRACTPlants appear to be almost an exclusive source of medicine to the worlds’ gradually increasing population with substances derived from them constituting a big percentage of all prescribed conventional medicines and other products. This puts pressure on the demand for medicinal plants, most of which are sourced from the wild. Zanthoxylum gilletii is an African indigenous deciduous tree which is overexploited for its medicinal use among many communities. This species has its habitat e...

Genetic Basis Of Striga Hermonthica (Del.) Benth Resistance In Wild Sorghum Accessions

ABSTRACTStriga weeds are root parasitic plants that affect production of food in sub-Saharan Africa. Striga genus includes species; Striga hermonthica, S. gesnerioides, S. aspera, S. asiatica and S. forbesii with S. hermonthica being the most widely spread in the semi-arid tropical African zones. The most effective Striga control strategy is to exploit natural resistance. Wild grasses contain a resistance mechanism that enables them to resist Striga infection resulting in low Striga quantity ...

In Vitro Antibacterial Activities Of Dichloromethane: Methanol Extracts Of Fuerstia Africana, Polygala Sphenoptera And Centella Asiatica Against Selected Bacteria

ABSTRACTBacterial infections are responsible for numerous deaths every year worldwide. On average, 80% of the African populations cannot afford conventional drugs. Moreover, many synthetic antibiotics are associated with side effects and progressive increase in antimicrobial resistance. Currently, there is growing interest in discovering new antibacterial agents from medicinal plants. About 60% of the population living in developing countries depends on herbal remedies for healthcare needs. T...

In Vitro Antibacterial And Antioxidant Activities Of Methanolic And Dichloromethanolic Seed Extracts Of Kenyan Annona Squamosalinn

ABSTRACTEnterobacterial constitute a large family of Gram-negative bacteria which reside in the intestines of the animals and can be pathogenic. Penicillins and fluoroquinolones have been used as antibiotics to combat enterobacterial infections. Challenges in treatment of enterobacterial infections with conventional drugs have led the physicians to opt for phyto products and other alternative medicine for treatment of enterobacterial infections. Heavy bacterial l...

Antidiabetic Activity And Safety Of Aloe Volkensii, Acacia Nilotica, Euclea Divinorum, Rhoicissus Tridentata, Cynanchum Viminale And Urtica Dioica In Mice

ABSTRACTDiabetes is increasingly affecting a growing number of patients and seriously reducing their quality of life. Use of conventional drugs in diabetes management is expensive, thus, unaffordable to most patients. Furthermore most of these conventional drugs are associated with undesirable side effects. Incorporation of herbal medicine into conventional healthcare system may significantly improve the overall management of Diabetes. Evaluation of efficacy and safety by scientific method is...

Antimicrobial Activity And Phytochemical Profiles Of Warburgia Ugandensis Sprague (Canellaceae) Extracts From Different Populations Across The Kenyan Rift Valley

ABSTRACTWarburgia ugandensis Sprague is a highly valued medicinal plant which is over-exploited for its medicinal use among many communities. Encroachment and fragmentation of the species habitat has led to a notable decrease in its population size and distribution to the level that warrant some conservation efforts. Moreover, information on diversity in its antimicrobial activity and phytochemical profiles is lacking. The aim of this study was to evaluate variations in antimicrobial activity...

Enhancement Of Resistance Against Colletotrichum Gloeosporioides In Cassava Over-Expressing Rice Thaumatin-Like Protein (Pr-5) Gene

ABSTRACTCassava (Manihot esculenta Crantz), is an energy giving food and has a crucial role in many of the world‟s least developed countries by providing not only food but also economic security. However, its productivity has been hampered by constraints that reduce yields. One of the biotic constraints is cassava anthracnose disease (CAD) caused by pathogen Colletotrichum gloeosporioides, results into more than 30 per cent reduction of produce in the fields. The use of conventional methods...

Sustainability Of Information And Communication Technology Projects In Public Organisations In Kenya; A Case Of Kenya Revenue Authority

ABSTRACTThe emergence of Information and communication technologies (ICTs), and e-Government, has made it possible to improve efficiency and effectiveness of internal administration within government and to re-locate government service from government offices to locations closer to the citizens. However, in its effort to have ICT systems that make these services available to citizens, most of the system projects have not been sustainable as the systems do not last or achieve the objective the...

Phenotypic Characterization And Genetic Diversity Studies Of Selected Rice (Oryza Sativa L.) Populations Based On Aroma And Cooked Kernel Elongation

    ABSTRACTRice (Oryza sativa L.) is the main staple food for more than half of the world’spopulation. Improving cooking and eating quality of rice is one of the importantobjectives of many plant breeding programs. Aroma and cooked kernel elongation aretwo critical parameters that determine the market value, cooking and eating qualitiesof rice. The objective of this study was to evaluate the phenotypic and geneticdiversity of thirteen (13) Oryza sativa L. populati...

The research designs adopted for this study are ex-post facto and survey which was conducted using a well structured questionnaire to obtain information. The sampling designs adopted are simple random sampling for questionnaire distribution and judgemental sampling for the selection of...

Estimation Of Inter-City Travel Demand For Public Road Transport From Owerri To Some Selected Cities In Nigeria

ABSTRACT This study calibrates an intercity travel demand model which uses the principal structural variables that have been identified in the literature. It uses a robust econometric method which has been little applied in the sphere of land transport in Nigeria. This research develops an urban public travel demand model for 19 directional O-D city-pair network originating from Owerri Urban. Using revealed preference data from the period of 2014 to 2016 which was filtered into 207 obs...

Elemental Analysis Of Bills Of Quantites For The Construction Of Bungalow Buildings In Owerri

ABSTRACT Dissatisfaction expressed by clients on the poor performance and level of service received from construction industry operators especially professionals gave birth to the need for this study.
