The ethnobotany of the Midzichenda tribes of the coastal forest areas in Kenya: 1. General perspective and non-medicinal plant uses
(African Journals Online, 2003)The coastal forests of Kenya represent a rare and threatened forest type, rich in biodiversity, with an estimated flora of over 3 000 plant taxa, of which about 550 taxa are endemic. The existing forest patches include ... -
The ethnobotany of the Midzichenda tribes of the coastal forest areas in Kenya: 2. Medicinal plant uses
(Refdoc, 2003)The Midzichenda have relied on plant resources for their basic needs, which included medicinal use, for centuries. This paper presents an inventory of some of the indigenous knowledge on medicinal plant uses of three ... -
EX VIVO INTERFERON-GAMMA IMMUNE RESPONSE TO THROMBOSPONDIN-RELATED ADHESIVE PROTEIN IN COASTAL KENYANS: LONGEVITY AND RISK OF PLASMODIUM FALCIPARUM INFECTION
(American Journal of Tropical Medicine and Hygiene, 2003)Abstract. Thrombospondin-related adhesive protein (TRAP) of Plasmodium falciparum iscurrently being tested in human vaccine studies. However, its natural reactivity in the field remainspoorly characterized. More than 40% ... -
Age-Specific Immunoglobulin G (IgG) and IgA to Pneumococcal Protein Antigens in a Population in Coastal Kenya
(Infection and Immunity, 2004-06)Streptococcus pneumoniae is the primary etiological agent of community-acquired pneumonia and a major cause of meningitis and bacteremia. Three conserved pneumococcal proteins—pneumolysin, pneumococcal surface adhesin A ... -
Lectin Variation in Members of Rhizoctonia Species
(J-STAGE, 2004-09-30)Isolates from two multinucleate Rhizoctonia species, namely Rhizoctonia solani and Rhizoctonia circinata, and binucleate Rhizoctonia spp., were evaluated for the presence of lectins, using human erythrocytes. Isolates from ... -
Biology of the marbled lungfish, Protopterus aethiopicus Heckel, in Lake Baringo, Kenya
(Wiley Online Library, 2004-12)In this paper we provide life history characteristics for an introduced marbled lungfish (Protopterus aethiopicus) population in Lake Baringo, Kenya, including their length–weight relationship, body condition, fecundity, ... -
Movement and habitat use by the marbled lungfish Protopterus aethiopicus Heckel 1851 in Lake Baringo, Kenya
(Kluwer Academic Publishers, 2005-03)The marbled lungfish, Protopterus aethiopicus, a recent introduction into Lake Baringo, Kenya is now an important commercial species there. Because little is known about its behaviour, we used ultrasonic telemetry to ... -
Sickle Cell Trait and the Risk of Plasmodium falciparum Malaria and Other Childhood Diseases
(Journal of Infectious Diseases, 2005-07)Background—The gene for sickle hemoglobin (HbS) is a prime example of natural selection. It is generally believed that its current prevalence in many tropical populations reflects selection for the carrier form (sickle ... -
CELLULAR REACTIVITY TO THE P. FALCIPARUM PROTEIN TRAP IN ADULT KENYANS: NOVEL EPITOPES, COMPLEX CYTOKINE PATTERNS, AND THE IMPACT OF NATURAL ANTIGENIC VARIATION
(American Journal of Tropical Medicine and Hygiene, 2006)Malaria vaccines based on thrombospondin-related adhesive protein of Plasmodium falciparum (Pf TRAP) are currently undergoing clinical trials in humans. This study was designed to investigate naturally acquired cellular ... -
A New Subgroup of Rhizoctonia AG-D, AG-D III, Obtained from Japanese Zoysia Grass Exhibiting Symptoms of a New Disease
(The American Phytopathological Society, 2006)Hayakawa, T., Toda, T., Ping, Q., Mghalu, J. M., Yaguchi, S., and Hyakumachi, M. 2006. A new subgroup of Rhizoctonia AG-D, AG-D III, obtained from Japanese zoysia grass exhibiting symptoms of a new disease. Plant Dis. ... -
Marbled lungfish growth rates in Lake Baringo, Kenya, estimated by mark-recapture
(Wiley Online Library, 2006-02)Mark-recapture was used to quantify the relationship between body mass (MT) and individual growth rates of sub-adult marbled lungfish Protopterus aethiopicus in Lake Baringo, Kenya. Specific growth rate (in mass) was found ... -
The Effect of aþ-Thalassaemia on the Incidence of Malaria and Other Diseases in Children Living on the Coast of Kenya
(PLos Medicine, 2006-04-18)Background The a-thalassaemias are the commonest genetic disorders of humans. It is generally believed that this high frequency reflects selection through a survival advantage against death from malaria; nevertheless, ... -
Growth and economic performance of Nile tilapia (Oreochromis niloticus L.) fed on three brans (maize, wheat and rice) in fertilized ponds
(Wiley Online Library, 2006-06)Nile tilapia (Oreochromis niloticus L.) was fed rice bran (RB), wheat bran (WB) and maize bran (MB) at 1.5% body weight. Fingerlings averaging 14 g were stocked at 19 462 fish ha−1 in three treatments with six replicates ... -
Genetic variation in the marbled lungfish Protopterus aethiopicus in Lake Victoria and introduction to Lake Baringo, Kenya
(ResearchGate, 2006-11)Marbled lungfish Protopterus aethiopicus in Lake Victoria and two nearby smaller lakes were found to have high levels of DNA sequence variation in their mitochondrial control regions (35 haplotypes in 61 fish) but no ... -
A New Subgroup of Rhizoctonia AG-D, AG-D III, Obtained from Japanese Zoysia Grass Exhibiting Symptoms of a New Disease
(APS Journal, 2006-11)Isolates of an unidentified Rhizoctonia sp. (UN isolates) were obtained from Japanese zoysia grass (Zoysia japonica Steud) that exhibited symptoms of a new sheath rot disease. UN isolates were binucleate and showed hyphal ... -
