Interaction of Phaseolus vulgaris with thermotolerant isolates of Rhizobium leguminosarum biovarphaseoli from Kenyan soils Interaction dePhaseolus vulgaris avec des isolats thermo-tolérants deRhizobium leguminosarum biovarPhaseoli de sols du Kenya
(Kluwer Academic Publishers, 1989)Thermotolerant strains of Rhizobium leguminosarum biovarphaseoli were isolated from nodules of Phaseolus vulgaris grown in Kenyan soils, where high soil temperatures often exceed 40°C during sunny days. The isolates varied ... -
The influence of PH on the recovery of contaminating micro-organisms from honey
(University of Nairobi, 1992)Accurate and sensitive methods for recovering contaminating micro-organisms from honey are required for an adequate control of the hygienic quality of the product. Most of these micro-organisms would be expected to be ... -
Coenzyme Q10 prevented full blown splenomegaly and decreased melarsoprol-induced reactive encephalopathy in mice infected with Trypanosoma brucei rhodesiense
(Journal of Coastal Life Medicine, 1997)Objective: To establish the modulatory effects of coenzyme Q10 on experimental trypanosome infections in mice and evaluate the risk of occurrence and severity of melarsoprol-induced post treatment reactive encephalopathy ... -
Biological nitrogen fixation in selected legumes of the semi-arid Makueni District of Southeast Kenya
(Der Tropenlandwirt-Journal of Agriculture in the Tropics and Subtropics, 1999)The major objective of this study was to investigate biological nitrogen fixation in two main legumes (green gram and common bean) grown in semi-arid southeast Kenya. Nodulation experiments on the two legumes were carried ... -
Studies on the Ecophysiology of Locally Suitable Cultivars of Food Crops and Soil Fertility Monitoring in the Semi-arid Areas of Southeast Kenya: A Final Report on a Collaborative Research Project Between Kenyatta University, Nairobi/Kenya, and the University of Trier, Germany
(Geographische Gesellschaft Trier, 2000) -
Crop water relationships and thermal adaptation of Kathika beans (Phaseolus vulgaris L.) and green grams (Vigna radiata L. Wilczek) with special reference to temporal patterns of potential growth in the drylands of SE-Kenya
(Academic Press, 2001)High soil temperatures influence seedling emergence as well as the performance of plant organs and yields. Temperatures of above 40°C were recorded in the topsoil of the Ferralsols of the semi-arid areas of SE-Kenya during ... -
Nitrogen fixation by common bean (Phaseolus vulgaris L.) in pure and mixed stands in semi-arid south-east Kenya
(Elsevier, 2001)Research was carried out in the field on the effect of intercropping common bean and maize crops in a semi-arid zone of south-east Kenya over two rainy seasons in 1997. The experimental design was a randomised complete ... -
Kinetics of the Alkaline Phosphatase Catalyzed Hydrolysis of Disodium p-Nitrophenyl Phosphate: Effects of Carbohydrate Additives, Low Temperature, and Freezing
(PubMed, 2004)The alkaline phosphatase catalyzed hydrolysis of disodium-p-nitrophenyl phosphate was studied in four model systems comprising sucrose, maltodextrin, carboxymethylcellulose (CMC), and CMC-lactose in a temperature range of ... -
Proinflammatory cytokine expression in the early phase of Trypanosoma brucei rhodesiense infection in vervet monkeys (Cercopithecus aethiops)
(2004)A vervet monkey model of trypanosomiasis was used to study inflammatory cytokine responses in serum and cerebrospinal fuid (CSF). Gamma interferon levels were transiently up-regulated in serum between days 6 and 8 of ... -
Influence of cyclophosphamide on the haematological profile of laboratory bred African soft-furred rats (Mastomys natalensis)
(2005)The African soft-furred rat (Mastomys natalensis) has been shown to be a possible model for propagation of Trypanosoma brucei gambiense. This study aimed at determining the baseline biological reference values and reproductive ... -
Population levels of indigenous bradyrhizobia nodulating promiscuous soybean in two Kenyan soils of the semi-arid and semi-humid agroecological zones
(Journal of Agriculture and Rural Development in the Tropics and Subtropics (JARTS), 2006)Soybeans grown in Africa have been selected to nodulate effectively with indigenous Bradyrhizobium spp. populations since Bradyrhizobium japonicum populations are considered absent or in very low numbers in African soils. ... -
Antibiotic resistance of bacteria isolated from Nairobi River
(2006)This study aimed to evaluate the antibiotic resistance of bacteria isolated from six sites along the pollution gradient of Nairobi River. Bacteria were isolated by standard Methods and grouped into 3 categories; enteric ... -
Isolation, molecular characterization and evaluation of local isolates of bacillus thuringiensis against the larger grain borer Prostephanus Truncatus (Horn) And The Maize Weevil Sitophilus Zeamais (Motsch)
(Kenya Agricultural Research Institute, Nairobi (Kenya), 2006) -
Haematology of experimental Trypanosoma brucei rhodesiense infection in vervet monkeys
(African Journal of Health Sciences,, 2006)Haematological aberrations associated with human infective trypanosomes were investigated in the vervet monkey model of the Rhodesian sleeping sickness. Four monkeys were infected intravenously with 104 Trypanosoma brucei ...
