Xanthomonas campestris pv. musacearum (Xcm) causes a disease on banana (Musa spp.) and enset (Ensete known as xanthomonas wilt (BXW). Recent studies have shown that Xcm is strain of X. vasicola (Aritua et al., 2008). However, the status pathovars within species remains unclear. Prior to its discovery in Uganda October 2001, had been limited Ethiopia (first reported 1968). Since then has spread Democratic Republic Congo Rwanda (observed May 2004 September 2005 respectively). BXW can cause...
Thermophilic composting is a promising method of sanitizing pathogens in manure and source agriculturally important thermostable enzymes microorganisms from organic wastes. Despite the extensive studies on compost prokaryotes, shifts microbial profiles under influence various green materials days are still not well understood, considering complexity material sources. Here, effect regimens diversity, abundance, metabolic capacity prokaryotic communities thermophilic environment was...
Fusarium species are a significant component of the set fungi associated with cassava root rot. Yield losses due to rot average 0.5 1 ton/ha but >3 ton/ha, an equivalent 15 20% yield, often occur. This paper reviews previous work on and summarizes few recent studies disease. Our in Cameroon showed that 30% rotted tubers were infected by spp. 12 months after planting represented 25% all fungal isolates recovered. Other commonly recovered Botryodiplodia theobromae Armillaria Numerous...
Healthcare workers (HCWs) shortage is a challenge facing health systems managers worldwide. The World Health Organization (WHO) projects shortfall of 10 million HCWs by 2030, mostly in low-income countries. leads to high workload, poor HCW performance and undesirable patient outcomes. Implementation Multi-Months Scripting (MMS) WHO guidelines reduces load HIV/AIDS outpatient clinics. study aims demonstrate policymakers, Systems Managers (HSMs), HCWs, stakeholders that implementation MMS...
Background and Objectives Blood safety sufficiency are major challenges in Kenya other sub‐Saharan African countries forcing many to rely on family replacement donors (FRD). We analysed data from a national AIDS indicator survey describe blood potential risks of transfusion transmissible infections (TTI) comparing voluntary FRD. Materials Methods A population‐based, cross‐sectional was conducted 2007 among 15‐ 64‐ year‐olds. Consenting participants were interviewed about donation history...
Early blight (EB) caused by Alternaria solani is one of the most devastating tomato diseases in Kenya and often managed application synthetic fungicides. However, there have been reports from farmers about declining efficacy some These suggest that A. populations could be developing resistance to commonly used In this study, we surveyed 175 fields, sampled 3 major producing counties Kenya, determine status EB, management practices, fungicide use factors contribute development fungicides...
A semiselective medium was developed for isolating Xanthomonas campestris pv. musacearum ( Xcm ) from infected banana plants, soil and insect vectors. The new named cellobiose‐cephalexin agar (CCA) it contained (L −1 ): 1 g yeast extract, glucose, peptone, NH 4 Cl, MgSO ·7H 2 O, 3 K HPO , beef 10 cellobiose, 14 agar, 40 mg cephalexin, 5‐fluorouracil 120 cycloheximide. evaluated selectivity using 21 bacterial isolates plating efficiency . included a soilborne species three pathogenic strains...
This study sought to analyze the determinants of vertical and horizontal integration among smallholder dairy farmers in Lower Central Kenya. Integration leads high gross margins, influences choice marketing channel improves market participation, encouraging commercialization farming. A logit regression model was used determine likelihood a household integrate vertically or horizontally its enterprise. multistage sampling technique used, data collected from 288 small holder Kiambu County....
Abstract Invasive alien species (IAS) rank among the most significant drivers of extinction and ecosystem degradation resulting in impacts on socio-economic development. The recent exponential spread IAS Africa is attributed to poor border biosecurity due porous borders that have failed prevent initial introductions. In addition, countries lack adequate information about potential invasions limited capacity reduce risk invasions. Horizon scanning an approach prioritises risks through rapid...
This study evaluated the effects of Bacillus amyloliquefaciens D203 encapsulated in alginate-bentonite coating enriched with titanium nanoparticles on rice germination and Magnaporthe oryzae infection. Seed was achieved using ionic gelation/extrusion method modifications. The investigated various concentrations strain biomass bacterial release from beads, along its influence detached leaves. Results showed that treatment a cell suspension (2 × 107 CFU/ml) significantly enhanced root shoot...
Objective: The aim of the study was to estimate technical and cost efficiencies smallholder dairy farms in Kenya (Embu Meru counties).Methodology results: Data were collected through a cross-sectional survey from 135 (96 Embu 39 Meru) randomly sampled using semi-structured questionnaires. Stochastic frontier production functions estimated maximum likelihood estimation (MLE)technique. It revealed zero-grazed herds four animals (mainly Friesians Ayrshires) on two-acre sized that practice mixed...
Thermophilic composting is a promising soil and waste management approach involving diverse micro macro-organisms, including eukaryotes. Due to sub-optimal amounts of nutrients in manure, supplemental feedstock materials such as Lantana camara, Tithonia diversifolia twigs are used composting. These have, however, been reported have antimicrobial activity in-vitro experiments. Furthermore, the phytochemical analysis has shown differences their complexities, thus possibly requiring various...
