Phylogenetic relationships within and among Brassica species from RAPD loci associated with blackleg resistance
(2008)The genus Brassica comprises economically important oilseed and vegetable crops. Their susceptibility to fungal diseases such as blackleg causes yield loss. In this study, thirty accessions from USDA germplasm collection ... -
Nuclear ribosomal DNA diversity of a cotton pest (Rotylenchulus reniformis) in the United States
(2008)The reniform nematode (Rotylenchulus reniformis) has emerged as a major cotton pest in the United States. A recent analysis of over 20 amphimictic populations of this pest from the US and three other countries has shown ... -
Genetic Variation Within Two Sympatric Spotted Gum Eucalypts Exceeds Between Taxa Variation
(2007)Population substructure and hybridization, among other factors, have the potential to cause erroneous associations in linkage disequilibrium (LD) mapping. Two closely related spotted gum eucalypts, Corymbia variegata and ... -
Phylogenetics in plant biotechnology: principles, obstacles and opportunities for the resource poor
(2007)Phylogenetic inference has become routine for most studies of genetic variation among plant taxa. However, inferring phylogenies can be confounded by both biological and computational or statistical complexities, resulting ... -
Nuclear ribosomal pseudogenes resolve a corroborated monophyly of the eucalypt genus Corymbia despite misleading hypotheses at functional ITS paralogs
(Science Direct, 2007)Divergent paralogs can create both obstacles and opportunities for phylogenetic reconstruction. Phylogenetic relationships among eucalypt genera have been incongruent among datasets in previous studies, where morphological ... -
Microsatellites retain phylogenetic signals across genera in eucalypts (Myrtaceae)
(2007)The utility of microsatellites (SSRs) in reconstructing phylogenies is largely confined to studies below the genus level, due to the potential of homoplasy resulting from allele size range constraints and poor SSR ... -
Hybridization of banteng (Bos javanicus) and zebu (Bos indicus) revealed by mitochondrial DNA, satellite DNA, AFLP and microsatellites
(2003)Hybridization between wild and domestic bovine species occurs worldwide either spontaneously or by organized crossing. We have analysed hybridization of banteng (Bos javanicus) and zebu (Bos indicus) in south-east Asian ... -
Genetic Diversity and Relationships of Indigenous Kenyan Camel (Camelus dromedarius) Populations: implications for their Classification
(2003)The genetic diversity and relationships amongst the dromedary (Camelus dromedarius) populations are poorly documented. Four recognized Kenyan dromedary breeds (Somali, Turkana, Rendille, Gabbra) and dromedary from Pakistan ... -
African Pastoralism: Genetic Imprints of Origins and Migrations.
(2002)The genetic history of African cattle pastoralism is controversial and poorly understood. We reveal the genetic signatures of its origins, secondary movements, and differentiation through the study of 15 microsatellite ... -
A Kenyan perspective on the use of animals in science education and scientific research in Africa and prospects for improvement
(Faculty of Veterinary Medicine, 2011)Animal experimentation is common in Africa, a region that accords little priority on animal protection in comparison to economic and social development. The current study aimed at investigating the prevalence of animal ... -
Geographic distribution and frequency of a taurine Bos taurus and an indicine Bos indicus Y specific allele amongst sub-Saharan African cattle breeds
(2000)We report for the first time, and for the whole of sub-Saharan Africa, the geographical distribution and the frequency of an indicine and a taurine Y specific allele amongst African cattle breeds. A total of 984 males from ... -
Suppression of nociception by Ocimum masaiense root extract involves
(Faculty of Veterinary Medicine, 2011)The members of genus Ocimum find wide application in traditional medicine. The current study was undertaken to evaluate the probable mechanisms of antinociceptive action of chloroform/ethanol extracts of Ocimum masaiense ... -
Effects of dehydration and heat stress on food intake and dry matter digestibility in East African ruminants
(Faculty of Veterinary Medicine, 2008)Comparative investigations were made between wild and domestic ruminants from arid and semi-arid regions and those species from non-arid areas in an attempt to evaluate the adaptations of these ruminants in terms of the ... -
A Comparison of the Nutritional Quality of Kenya's Omena Fishmeal and (Lt) Anchovy Fishmeal Fed to Nile Tilapia (Oreochromis Niloticus Linn)
(2005)A study was done to determine the apparent digestibility and the nutritional and feeding values of Kenya s omena fish meal fed to tilapia Oreochromis niloticus, and to compare them with that of a high quality (LT) anchovy ... -
Effects of opioids in the formalin test in the Speke’s hinged tortoise (Kinixy’s)
(2009)Little is known about analgesia in lower vertebrates such as the Speke’s hinged tortoise (Kinixy’s spekii), yet of late they are increasingly being adopted as pets. The effects of morphine (5, 7.5, 10 and 20 mg⁄ kg), ... -
Transepithelial potential in the Magadi tilapia, a fish living
(Faculty of Veterinary Medicine, 2005)We investigated the transepithelial potential (TEP) and its responses to changes in the external medium in Alcolapia grahami, a small cichlid fish living in Lake Magadi, Kenya. Magadi water is extremely alkaline (pH = ... -
In vitro study of the effects of khat (Catha edulis Forsk) extract on isolated mouse interstitial cells
(Faculty of Veterinary Medicine, 2007)Isolated mouse interstitial cells were incubated with different concentrations of khat (Catha edulis) extract (0.06 mg/ml, 0.6 mg/ml, 6 mg/ml, 30 mg/ml and 60 mg/ml) and cell viability as well as testosterone concentration ... -
Digestibility and feeding value of some feed ingredients fed to tilapia Oreochromis niloticus (l.)
(2001)The apparent digestibility of protein, organic matter and energy of high-fibre and fibre-reduced sun¬flower cakes, Kenya's 'omena' fishmeal, anchovy fishmeal and wheat bran were investigated in tilapia Oreochromis niloticus ... -
Khat: A Boon or Bane to Humanity
(Faculty of Veterinary Medicine, 2010)Khat, an evergreen shrub habitually ingested for its euphoric and stimulatory effects, is grown mainly in eastern Africa and south-western Arabia. Its consumption has, for a long time, been restricted to areas close to ... -
Clinical manifestation of experimental water intoxication in calves
(Faculty of Veterinary Medicine, 1998-06)Two trials of induction of water intoxication at weaning and I month after weaning were carried out in 5 test and 5 control calves. The test calves did not have any access to salts and water other than that contained in ...
