Isolation and characterization of bacillus species from soil in Ngere tea catchment area of Murang’a county, Kenya
(2014-07)Bacteria are a very diverse group of organisms in soil, and major taxonomic groups are represented in most soils. The extent of the diversity of microorganisms in soil is seen to be critical to the maintenance of soil ... -
Evaluation of an antigen-antibody “combination” enzyme linked immunosorbent assay for diagnosis
(2014-10)Background Development of “combination” assays detecting in parallel, within a single test, Hepatitis C Virus (HCV) antigens and antibodies, not only reduces the window period in HCV-infection but also costs. Reduction ... -
Evaluation of an Antigen-Antibody “Combination” Enzyme Linked Immunosorbent Assay For Diagnosis Of Hepatitis C Virus Infections
(2014-10)BACKGROUND: Development of “combination” assays detecting in parallel, within a single test, Hepatitis C Virus (HCV) antigens and antibodies, not only reduces the window period in HCV-infection but also costs. Reduction ... -
Genetic Diversity of Cassava Mutants, Hybrids and Landraces Using Simple Sequence Repeat Markers
(SCIENCEDOMAIN international, 2014-10-11)Aims: Cassava (Manihot esculenta Crantz) is a crop with largely unexplored and unexplained potentially valuable genetic variability. The knowledge and understanding of the extent of genetic variation of cassava germplasm ... -
Screening for Water Deficit Tolerance, Relative Growth Analysis and Agrobacterium-Infectivity in Tropical Maize [Zea Mays L.] Inbred Lines in Nairobi, Kenya
(2014-12)The gap between maize demand and regional supply is increasing as small-holder farmers grapple with many challenges, key among them drought. Research in identifying maize lines that are tolerant to water deficit and that ... -
Hypoglycemic effect of Helichrysum odoratissimum in alloxan induced diabetic mice
(2015)Diabetes mellitus is a disease of antiquity with worrying global incidence and prevalence. Conventional management and/or treatment interventions have been hampered by drawbacks like high costs, inaccessibility, likelihood ... -
Cultural Characterization of Fungi Isolated From Oil Contaminated Soils
(IISTE, 2015)Application of Fungi for effective removal of hydrocarbon contamination from soil is being considered as the better option when it comes to biodegradation. Other method like physical and chemical bioremediation leads to ... -
Field Abundance Patterns and Odor-Mediated Host Choice by Clover Seed Weevils, Apion fulvipes and Apion trifolii (Coleoptera: Apionidae)
(2015-02)The clover seed weevils Apion fulvipes Geoffroy, 1785 and Apion trifolii L., 1768 (Coleoptera: Apionidae) cause major losses to seed production of white clover (Trifolium repens L.) and red clover (Trifolium pratense ... -
