Mutation EthAW21R confers co-resistance to prothionamide and ethionamide in both Mycobacterium bovis BCG and Mycobacterium tuberculosis H37Rv
(Dove Press, 2018-06)
Ethionamide (ETA) and prothionamide (PRO) are interchangeably used in tuberculosis
(TB) chemotherapy regimens. Subtle discrepancies between biochemical and genetic
information on the modes of sensitivity and resistance ...
Coevolutionary fine-tuning: evidence for genetic tracking between a specialist wasp parasitoid and its aphid host in a dual metapopulation interaction
(Cambridge University Press, 2012-04)
In the interaction between two ecologically-associated species, the population structure of one species may affect the population structure of the other. Here, we examine the population structures of the aphid Metopeurum ...
A survey of root knot nematodes and resistance to Meloidogyne incognita in sweet potato varieties from Kenyan fields
(Elsevier, 2016-11)
The root knot nematode, Meloidogyne is one of the most economically damaging plant parasitic nematode
groups, and are widely distributed in Kenyan agro-ecosystems. The aim of this study was to
determine the diversity of ...
Seagrass Removal Leads to Rapid Changes in Fauna and Loss of Carbon
(Frontiers, 2019-03)
Seagrass habitats are important natural carbon sinks, with an average of ∼14 kg C
m−2 buried in their sediments. The fate of this carbon following seagrass removal
or damage has major environmental implications but is ...
Bacteria and Archaea diversity within the hot springs of Lake Magadi and Little Magadi in Kenya
(2016-07)
Background: Lake Magadi and little Magadi are hypersaline, alkaline lakes situated in the southern part of Kenyan
Rift Valley. Solutes are supplied mainly by a series of alkaline hot springs with temperatures as high as ...
Isolation and characterization of some gut microbial symbionts from fungus-cultivating termites (Macrotermes and Odontotermes spp.)
(2016-07)
Microbiota of termites is crucial for nitrogen cycle activities and degradation of recalcitrant components
of plant biomass that influence soil structure and carbon mineralization in tropical and subtropical
regions. The ...
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 ...
Potential human pathogenic bacteria in five hot springs in Eritrea revealed by next generation sequencing
(PLOS ONE, 2018-03)
Human pathogens can survive and grow in hot springs. For water quality assessment,
Escherichia coli or Enterococci are the main thermotolerant enteric bacteria commonly used
to estimate the load of pathogenic bacteria ...
Temporal genetic structuring of a specialist parasitoid, Lysiphlebus hirticornis Mackauer (Hymenoptera: Braconidae) attacking a specialist aphid on tansy
(2010-11)
In insect species characterized by inbreeding, limited dispersal, and a metapopulation structure, high genetic
differentiation and reduced genetic diversity within local populations are expected. Using the model ...
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 ...
