Mapping brucellosis risk in Kenya and its implications for control strategies in sub‑Saharan Africa
(UoEm, 2023-11-30)In Sub-Saharan Africa (SSA), effective brucellosis control is limited, in part, by the lack of long-term commitments by governments to control the disease and the absence of reliable national human and livestock population-based ... -
March 2019 dengue fever outbreak at the Kenyan south coast involving dengue virus serotype 3, genotypes III and V
(Plos, 2022-03)The first description of a disease resembling dengue fever (DF) was in the 15 century slave trade era by Spanish sailors visiting the Tanzania coast. The disease, then associated with evil spirits is now known to be ... -
Mass developments of a small sized ecotype of Arthrospira fusiformis in Lake Oloidien, Kenya, a new feeding ground for Lesser Flamingos in East Africa
(2013)The Lesser Flamingos constantly commute between the soda lakes of East Africa in search of food. Their preferred food, the cyanobacterium Arthrospira fusiformis, usually establishes dense populations in saline–alkaline ... -
Mass developments of the cyanobacteria Anabaenopsis and Cyanospira (Nostocales) in the soda lakes of Kenya: ecological and systematic implications
(2013)The food web of the saline–alkaline lakes of East Africa is characterised by a unique interaction between the Lesser Flamingos as consumer birds and the cyanobacterium Arthrospira fusiformis as the primary producer. ... -
Mating Strategies in Solitary Aphid Parasitoids: Effect of Patch Residence Time and Ant Attendance
(Springer, 2012-01)Mate finding and dispersal from the natal patch in parasitoid Hymenoptera are influenced by the availability of host resources and interactions with other organisms. We compared the mating behavior of three solitary aphid ... -
Mating Strategies in Solitary Aphid Parasitoids: Effect of Patch Residence Time and Ant Attendance
(2011-06)Mate finding and dispersal from the natal patch in parasitoid Hymenoptera are influenced by the availability of host resources and interactions with other organisms. We compared the mating behavior of three solitary aphid ... -
Measuring the role of seagrasses in regulating sediment surface elevation
(Scientific Reports, 2017-09)Seagrass meadows provide numerous ecosystem services and their rapid global loss may reduce human welfare as well as ecological integrity. In common with the other ‘blue carbon’ habitats (mangroves and tidal marshes) ... -
Metabolic traits of an uncultured archaeal lineage -MSBL1- from brine pools of the Red Sea
(2016-01)The candidate Division MSBL1 (Mediterranean Sea Brine Lakes 1) comprises a monophyletic group of uncultured archaea found in different hypersaline environments. Previous studies propose methanogenesis as the main metabolism. ... -
Metal Status of Nairobi Riverwaters and Their Bioaccumulation in Labeo Cylindricus
(Springer, 2005-03-03)This study focused on the analysis of metals in water and fish from Nairobi River. Water from Kikuyu, Kawangware, Chiromo, Eastleigh, Njiru and Fourteen Falls along the Nairobi River was analyzed for the presence of metals. ... -
Metal status of Nairobi riverwaters and their bioaccumulation in Labeo cylindricus
(Academic Journals, 2005-03)This study focused on the analysis of metals in water and fish from Nairobi River. Water from Kikuyu, Kawangware, Chiromo, Eastleigh, Njiru and Fourteen Falls along the Nairobi River was analyzed for the presence of metals. ... -
Methods for early evaluation for resistance to bacterial blight of coffee
(Academic Journals, 2013)Bacterial Blight of Coffee (BBC) caused by Pseudomonas syringae pv garcae has become of major concern in Kenya due to its increasing incidence and severity. For decades, the disease was confined within and to the west of ... -
Microsatellites from Lysiphlebus hirticornis Mackauer (Hymenoptera: Braconidae), a specialist primary parasitoid attacking the specialist tansy aphid, Metopeurum fuscoviride Stroyan (Hemiptera: Aphididae)
(Blackwell Publishing Ltd, 2009-04)Nine polymorphic microsatellite loci were isolated from the specialist aphid parasitoid, Lysiphlebus hirticornis. In addition, two published loci from closely related Lysiphlebus species were also used. Allelic diversity ... -
Microsatellites from Lysiphlebus hirticornis Mackauer (Hymenoptera: Braconidae), a specialist primary parasitoid attacking the specialist tansy aphid, Metopeurum fuscoviride Stroyan (Hemiptera: Aphididae)
(2008-10)Nine polymorphic microsatellite loci were isolated from the specialist aphid parasitoid, Lysiphlebus hirticornis. In addition, two published loci from closely related Lysiphlebus species were also used. Allelic diversity ... -
Mitochondrial DNA variation of Bemisia tabaci (gennadius) (hemiptera: aleyrodidae) infesting cassava in Kenya

Molecular detection of uncultured cyanobacteria and aminotransferase domains for cyanotoxin production in sediments of different Kenyan lakes
(Blackwell Publishing Ltd, 2009-04-15)PCR-based denaturing gradient gel electrophoresis (DGGE) analysis of 16S rRNA gene fragments was used to identify the cyanobacterial phylotypes in sediments and plankton of saline–alkaline and freshwater lakes of Kenya. ... -
Molecular diversity of plankton in a tropical crater lake switching from hyposaline to subsaline conditions: Lake Oloidien, Kenya
(Springer, 2016-09)Salinity in the climate sensitive tropical endorheic crater lake Oloidien (Great African Rift Valley, Kenya) decreased from hyposaline to subsaline conditions during the period 2010–2015. The change in salinity was ... -
Molecular epidemiology of Brucella species in mixed livestock‑human ecosystems in Kenya
(Nature, 2021-03)Brucellosis, caused by several species of the genus Brucella, is a zoonotic disease that afects humans and animal species worldwide. Information on the Brucella species circulating in diferent hosts in Kenya is largely ... -
