Advances in the development of molecular genetic tools for Mycobacterium tuberculosis
(Elsevier, 2018-07)Mycobacterium tuberculosis, a Gram-positive bacterium of great clinical relevance, is a lethal pathogen owing to its complex physiological characteristics and development of drug resistance. Several molecular genetic ... -
Agro-morphological characterization of horned melon (Cucumis metuliferus) accessions from selected agro-ecological zones in Kenya
(Australian Journal of crop science, 2020-09)Morphological characterization of genotypes is fundamental in providing information on their genetic status to guide on their conservation and improvement. The objective of this study was to determine agro-morphological ... -
Agro-Morphological Characterization of Kenyan Slender Leaf (Crotalaria brevidens and C. ochroleuca) Accessions
(Hindawi, 2020-04)Slender leaf (Crotalaria spp) is among the indigenous and underutilized vegetables in Kenya whose production is limited to the Western and Coastal regions of the country. For a long time, this crop has been neglected in ... -
Amino acid neurotoxins in feathers of the Lesser Flamingo, Phoeniconaias minor
(Elsevier, 2013-01)The Lesser Flamingo (Phoeniconaias minor) is known to use cyanobacteria (primarily Arthrospira) as a major food source in the East African Rift Valley lakes. Periodically, mass mortalities have occurred, associated with ... -
Amplicon-based assessment of bacterial diversity and community structure in three tropical forest soils in Kenya
(Heliyon, 2022-11)Forest soils provide a multitude of habitats for diverse communities of bacteria. In this study, we selected three tropical forests in Kenya to determine the diversity and community structure of soil bacteria inhabiting ... -
Analysis of genetic diversity in Eucalyptus grandis (Hill ex Maiden) seed sources using inter simple sequence repeats (ISSR) molecular markers
(Academic Journals, 2008-07-04)Eucalyptus grandis is an economically important tree species that is native to the Australian continent and its northern neighbours, where it is grown primarily for its hard wood timber and pulp for paper industries. It ... -
Analysis of the cyanotoxins anatoxin-a and microcystins in Lesser Flamingo feathers.
(Taylor & Francis, 2006)Feathers from carcasses of the Lesser Flamingo (Phoeniconaias minor), which had died after ingesting cyanobacterial toxins (cyanotoxins) contained between 0.02 and 30.0 µg microcystin-LR equivalents per gram of feather ... -
Annotations of novel antennae-expressed genes in male Glossina morsitans morsitans tsetse flies
(Plos 1, 2022-08)Tsetse flies use antennal expressed genes to navigate their environment. While most canonical genes associated with chemoreception are annotated, potential gaps with important antennal genes are uncharacterized in Glossina ... -
Anti-inflammatory norhopanes from the root bark of Fagaropsis angolensis (Engl.) H.M.Gardner
(Elsevier, 2020-06-17)Two new norhopane derivatives namely 3β,6β,22-trihydroxy-7β,11α-di[(4-hydroxybenzoyl)oxy]-21αH-24- norhopa-4(23)-ene (1) and 3β,6β,22-trihydroxy-7β-[(4-hydroxybenzoyl)oxy]-21αH-24-norhopa-4(23)-ene (2) together with two ... -
Anti-plasmodial Activity of Some Kenyan Medicinal Plant Extracts Singly and in Combination with Chloroquine
(Wiley InterScience, 2004)Sixty organic and aqueous extracts of eleven plants used for the control of malaria by local communities in Kisii District, Kenya were screened for in vitro anti-plasmodial activity. The plants selection was based on ... -
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 ... -

Antimicrobial Activity of Warbugia Ugandensis against Gramnegative Multi‐Drug resistant Bacteria
(Jomo Kenyatta University of Agriculture and Technology, 2014)The rise in antibiotic resistance has resulted in decreasing numbers of effective antimicrobial agents available to treat infections caused by multi‐drug resistant (MDR) bacteria. This has necessitated a search for new ... -

Archaeal Diversity in the Haloalkaline Lake Elmenteita in Kenya
(Springer-Verlag, 2009-10-06)A non-culture approach was used to study the archaeal diversity in Lake Elmenteita, Kenya. Five different sampling points were selected randomly within the lake. Wet sediments and water samples were collected from each ... -
Assessment of Clofazimine and TB47 Combination Activity against Mycobacterium abscessus Using a Bioluminescent Approach
(American Society for Microbiology, 2020-02)Mycobacterium abscessus is intrinsically resistant to most antimicrobial agents. The emerging infections caused by M. abscessus and the lack of effective treatment call for rapid attention. Here, we intended to construct ... -
Assessment of Four Commercial Watermelon Cultivars and one Local Landrace for Their Response to Naturally Occurring Diseases Pests and Non-Pathogenic Disorders in Sub-Humid Tropical Conditions
(Asian Research Publishing Network (ARPN), 2008-09)Four commercial watermelon cultivars available in Kenya and one local landrace were evaluated for their susceptibility/resistance to naturally occurring diseases, pests and non-pathogenic disorders. The accessions included ... -
Assessment of Risk Predisposition to Human Papilloma Virus through Cervical Infections Screening of Women Attending an Outpatient Health Facility In Nairobi, Kenya
(2014)There is limited data on comparative disposition to cervical cancer among HPV infected women in Kenya. We aimed to determine the distribution of HPV infection, cervical abnormalities and infections commonly reported on ... -
