Additive main effects and multiplicative interaction analysis of genotype x environmental interaction among sweetpotato genotypes
(Journal of Animal & Plant Sciences, 2009)Sweetpotato is an important food, feed and cash crop in Eastern Africa. Highly stable and adaptable genotypes are important in sweetpotato productivity and evaluation across sites would form a basis for breeding varieties ... -
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 ... -
Are wild African lungfish obligate air breathers? Some evidence from radio telemetry
(Stellenbosch University Library, 2007)Laboratory studies have resulted in classification of the marbled African lungfish, Protopterus aethiopicus, as an obligate air-breather. However, there have been no investigations of the extent of dependence on aerial ... -
Aspects of the biology of Labeo cylindricus (Pisces: cyprinidae) in Lake Baringo, Kenya
(Wiley Online Library, 2012-09)Aspects of the biology of Labeo cylindricus from Lake Baringo were investigated, based on experimental beach seining and gillnetting between August and October 2007. The length–weight relationship indicated the species ... -
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, ... -
Bottom shrimp trawling impacts on species distribution and fishery dynamics; Ungwana Bay fishery Kenya before and after the 2006 trawl ban
(Springer Japan, 2012-03-01)The Malindi–Ungwana Bay fishery Kenya is one of the most important marine fisheries of the Western Indian Ocean. There are two fishing grounds: Formosa and Malindi, with a designated 5-nM no-trawl zone offshore. However, ... -
Breadth and Magnitude of Antibody Responses to Multiple Plasmodium falciparum Merozoite Antigens Are Associated with Protection from Clinical Malaria
(Infection and Immunity, 2008-02-23)Individuals living in areas where malaria is endemic are repeatedly exposed to many different malaria parasite antigens. Studies on naturally acquired antibody-mediated immunity to clinical malaria have largely focused ... -
Catch Composition, Abundance and Length-Weight Relationships of Groupers (Pisces: Serranidae) from Inshore Waters of Kenya
(African Journals Online, 2010-10)Abstract—Groupers (family Serranidae) support important artisanal fisheries in most of the Western Indian Ocean (WIO) region. However, despite their economic and ecological importance, they are poorly studied in the region. ... -
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 ... -
Clearing asymptomatic parasitaemia increases the specificity of the definition of mild febrile malaria
(Elsevier, 2007-08-15)Abstract In clinical trials, the specificity of the disease endpoint is critical to an accurate estimate of vaccine efficacy. We used a logistic regression model to analyse parasite densities among children before and ... -
Comparison of volatile blends and gene sequences of two isolates of Metarhizium anisopliae of different virulence and repellency toward the termite Macrotermes michaelseni
(The Journal of Experimental Biology, 2010-11-29)Previously, we reported an interesting relationship between virulence and repellency of different isolates of the fungus Metarhizium anisopliae towards the termite Macrotermes michaelseni: the higher the virulence of a ... -
Comparison of volatile blends and gene sequences of two isolates of Metarhizium anisopliae of different virulence and repellency toward the termite Macrotermes michaelseni.
(PudMed, 2011-03)Previously, we reported an interesting relationship between virulence and repellency of different isolates of the fungus Metarhizium anisopliae towards the termite Macrotermes michaelseni: the higher the virulence of a ... -
Comparison of Volatile Blends and Nucleotide Sequences of Two Beauveria Bassiana Isolates of Different Virulence and Repellency Towards the Termite Macrotermes Michealseni.
(2012)Isolates of the fungus Beauveria bassiana have different levels of virulence and repellency against the termite Macrotermes michaelseni. In the present study, we compared the volatile profiles and gene sequences of two ... -
Daily growth of young-of-the-year of the Baringo tilapia, Oreochromis niloticus baringoensis (Trewavas, 1983)
(2010)Otolith microstructure analysis was used to validate microincrement deposition rate and to determine daily growth rates of young-of-the-year (YOY) Baringo tilapia, Oreochromis niloticus baringoensis. Microincrement ... -
Determination of effective tow duration for estimation of fish and shellfish abundance in deeper-water bottom trawl surveys
(Springer Japan, 2011-07-01)Experimental trawl surveys were conducted to determine effective tow durations for estimating fish and shellfish abundances in deeper-water bottom trawl surveys. A total of 304 hauls were conducted in Kagoshima Bay, southern ... -
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, ... -
Effects of Greenhouse and Stocking Density on Growth and Survival of African Catfish ( Clarias gariepinus Burchell 1822) Fry Reared in High Altitude Kenya Regions
(http://www.ijsr.net/, 2012)Production of African catfish (Clarias gar iepinus) under culture in high altitude ar eas has faced challenges due to slow growth related to low temperatur es. This study was therefore designed to test the hypothesis ... -
