Hyphaene compressa, an important palm in the arid and semi-arid regions of Kenya
(2020-06)Background: Peasant agroecosystems in Kenya are considered to be a continuum of integrated traditional farming systems and natural ecosystem conservancy programs. Hyphaene compressa (doum palm) exists in arid and ... -
Cervical Dysplasia, Infection, and Phylogeny of Human Papillomavirus in HIV-Infected and HIV-Uninfected Women at a Reproductive Health Clinic in Nairobi, Kenya
(Hindawi, 2020-06)High risk human Papillomavirus (HPV) infections ultimately cause cervical cancer. Human Immunodefi ciency Virus (HIV) infected women often present with multiple high-risk HPV infections and are thus at a higher risk of ... -
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 ... -
Seroprevalence of foot-and-mouth disease virus in cattle herds raised in Maasai Mara ecosystem in Kenya
(Elsevier, 2020-03)A cross-sectional study was carried out to determine foot-and-mouth disease (FMD) seroprevalence and identify risk factors of exposure among cattle herds raised in three zones with different types of land use and ... -
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 ... -
Phylogenetic and morphological diversity of culturable cyanobacteria from Lake Magadi in Kenya
(2019-10)Lake Magadi is an alkaline saline Lake in Kenya, which lies on the Great Eastern Rift valley. Although the lake is characterized by extremes of salt, pH and temperature, it supports diverse groups of cyanobacteria. In ... -
Diversity of esterase and lipase producing haloalkaliphilic bacteria from Lake Magadi in Kenya
(2019-09)Lipids are hydrocarbons comprised of long‐chain fatty acids and are found in all living things. In the environment, microorganisms degrade them to obtain energy using esterases and lipases. These enzymes are nowadays ... -
Common Cerambycid Pheromone Components as Attractants for Longhorn Beetles (Cerambycidae) Breeding in Ephemeral Oak Substrates in Northern Europe
(Springer, 2019-06)Longhorn beetles are ecologically important insects in forest ecosystems as decomposers of woody substrates, microhabitat engineers, and as components of forest food webs. These species can be greatly affected both ... -
Plant Hybridization as an Alternative Technique in Plant Breeding Improvement
(2019-05)For ages, plant breeders have relied on the genetic variability that results from sexually crossing plants within the same species. However, the variability that exists within species populations is inadequate, hence the ... -
Prevalence and Risk Factors of Human Herpes Virus Type 8 (HHV-8), Human Immunodeficiency Virus-1 (HIV-1), and Syphilis among Female Sex Workers in Malindi, Kenya
(Hindawi, 2019-06)The prevalence of Human Herpes Virus type 8 (HHV-8), Human Immunodeficiency virus (HIV), and syphilis is high in Sub- Saharan Africa. Studies on HHV-8 in Kenya are few and data on its coinfection with HIV and syphilis ... -
Species composition, abundance and fishing methods of small-scale fisheries in the seagrass meadows of Gazi Bay, Kenya
(Routledge, 2019-05)Fisheries are important sources of livelihoods to coastal communities. In the tropics fishing is conducted from mangroves, seagrass meadows to coral reefs. Studies on fisheries in the tropics have focused on coral reef ... -
Infestation Levels and Molecular Identification Based on Mitochondrial COI Bar code Region of Five Invasive Gelechiidae Pest Species in Kenya
