Effect of metarhizium anisopliae and its complementation with phenylacetonitrile pheromone on reproductive potential and mortality of gregarious nymphs of schistocerca gregaria
(School of Biological Sciences, University of Nairobi, 2004-11)Recent concerns over possible human health problems and environmental damage resulting from large scale application of chemical' pesticides for desert locusts control have led to proposals for alternative control strategies. ... -
Adverse skin reactions to sulfadoxine-pyrimethamine in western Kenya: implications for malaria treatment strategies
(Department of Zoology, University of Nairobi, 1998)With the increasing problem of chloroquine-resistant falciparum malaria in Kenya, treatment with alternative drugs such as sulfadoxine-pyrimethamine is becoming common. One of the side-effects associated with the use ... -
A study of the butterfly diversity in the Arabuko-Sokoke forest, Kenya
(School of Mathematics, University of Nairobi, 1997)In this study the diversity of butterfly fauna in the Arabuko-Sokoke Forest is examined by looking into their population abundance and seasonality. Investigation of these were by means of systematic collecting and trapping, ... -
Pathogenesis and immune responses in HIV-l infected infants and children
(School of Biological Sciences, University of Nairobi, 2001)There are limited reports on HIV-l RNA load, CD4 T-Iymphocyte counts, anti-HIV-l antibody responses and age in relation to disease progression in HIV-1 infected untreated children in Africa. Understanding these parameters ... -
In vitro screening of bacillus strains for antagonism against selected phytopathogenic microorganisms and their potential use in biocontrol
(School of Biological Sciences, University of Nairobi, 2008-05)A total of 137 endospore-forming bacteria isolated and identified as members of the genus Bacillus in a previous study were tested for viability by subculturing onto fresh nutrient agar (NA) plates from slants in tubes ... -
A study of the factors influencing aphids as vectors of viral diseases of brassica Oleracea (kale and cabbage) in Kenya
(Department of Zoology, University of Nairobi, 2005-04)Aphids are insects of the Family Aphididae in the Order Homoptera. Their importance as pests is due to their ability to carry plant viruses, the effect of their sucking damage on the growth of plants and their rapid rate ... -
Diagnosis of acute bovine sarcocystosis using genomic DNA probes
(Department of Pathology and Microbiology, University of Prince Edward Island, 1994-01)DNA probes were prepared from a Sarcocystis cruzi sporozoite genomic library constructed in bacteriophage lambda gt 10. Of the 96 clones examined, 14 showed strong hybridisation to parasite DNA and were further analyzed. ... -
The in vivo identification of trypanosome proteins interacting with the Glossina midgut proteolytic lectin (GPL)
(Faculty of Medicine, University of Nairobi., 2008)Protein-protein interactions mediate in the transformation of parasites during the course of infection. The Glossina proteolytic lectin (Gpl) is associated with the transformation of the bloodstream trypomastigotes into ... -
Isolation of soil actinomycetes from different sites and screening for their antimicrobial activity
(Schoolof Biological Sciences College of Biological and Physical Sciences University of Nairobi, 2008)Screening of several microbes for bioactive compounds is an open avenue for discovery of novel bioactive compounds with varied functions as agricultural chemicals. The work done resulted in isolation of seventeen ... -
Comparing the effects of radiation-attenuated vaccine when administered either before or after praziquantel treatment in schistosoma mansoni infected balb/c mice
(Department of Zoology, University of Nairobi, 2006)Schistosomal vaccine candidates such as Paramyosin and Multiple antigen epitopes (MAP) are in different stages of development and clinical trials. However, it is probable that during initial field clinical trials, some ... -
Characterization of trypanosomosis resistance QTL, tir1, in the mouse
(Department of Zoology, University of Nairobi, 2000)In order to characterise the D17MIT16 BAC DNA clone which is part of a 1200 kilobase DNA insert believed to contain mouse trypanotolerance genes, restriction endonucleases were used to digest the insert for restriction ... -
Evaluation of leishmania major transmission by phlebotomus duboscqi in balb/c mice during sodium stibogluconate (pentostam) treatment.
(School of Biological Sciences, University of Nairobi, 1990)The mainstay treatment of leishmaniasis is pel tavalcnt antimony III the form of sodium stibogluconate (pentostarn'') and mcglumine antimoniate (glucatime"). The two drugs have been used with relative success for the ... -
Renormalizable gauges and radiative corrections in gauge theories
(Department of Physics, University of Nairobi, 1984)Radiative corrections in gauge theories are used to study physical processes on the basis of the standard electroweak model. The concepts of gauge invariance and gauge dependence are investigated by considering the ... -
Changes in soil organic carbon and soil nutrient levels of a natural semi-arid savanna brought under cultivation
(Department of Botany, University of Nairobi, 2002)The study was conducted between January 1997 and February 2000 in a semiarid area located at the University of Nairobi's Institute of Dryland Research, Development and Utilisation, located at Kibwezi. The purpose was to ... -
Nutrient productivity relationships in tropical Naivasha basin lakes; Kenya
(Department of Botany, Faculty of Science University of Nairobi, 1982)Nutrient availability and seasonal variation have often been cited as the principal factors controlling rates of primary productivity and phytoplankton abundance in tropical African lakes. Very few studies of nutrient ... -
UL marketing management decision support system
(2004)The title of this project is "UL marketing management decision support system" here referred to as UL-DSS. The system is designed to assist the sales and marketing managers III making more accurate and timely decisions ... -

(1979)Electrophoretically demonstrable variation was analyzed in ten enzymes encoded by fifteen genetic loci in samples from nine populations of five Zaprionus species from Kenya • frequencies were determined from ... -
Nitrogen fixation associated with maize plants (zea mays l.) in a temperate and a tropical soil
(Department of Botany, College of Biological and Physical Sciences, 1987)In the temperate soil, low rates of acetylene reduction activity were detected in excised roots of field grown maize without preincubation. A higher acetylene reduction activity (20 nmol C2H4/ g d.wt./ 24 h) was recorded ...
