Abstract Vaccination is a key control measure of COVID-19 by preventing severe effects disease outcomes, reducing hospitalization rates and death, increasing immunity. However, vaccination can affect the evolution adaptation SARS-CoV-2, largely through vaccine-induced immune pressure. Here we investigated intrahost recombination single nucleotide variations (iSNVs) on SARS-CoV-2 genome in non-vaccinated vaccinated sequences from Kenyan population to profile viral genetic adaptations driven...
The efficiency of cassava brown streak virus (CBSV) transmission by Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) and spiraling whitefly (Aleurodicus dispersus) Russell (Hom, was determined. utilized field collected adult populations fed on (allowed 48 h acquisition access feeding period (AAP)) CBSD (cassava disease) symptomatic leaves before transfer onto clean recipient plants. In subsequent experiments, numbers each species were varied per plant to determine the effect rate CBSV...
Abstract Cassava mosaic disease is caused by a complex of whitefly-transmitted begomoviruses, which often occur in co-infections. These viruses have bipartite genomes consisting DNA-A and DNA-B that are encapsidated into separate virions. Individual exist plants whitefly vectors as populations comprising both genome segments, can at different frequencies. Both segments required for infection, must be transmitted virus spread to occur. infected with African cassava (ACMV) and/or East Cameroon...
Abstract Cassava mosaic disease is caused by a complex of whitefly-transmitted begomovirus species, which often occur in mixed infections. These viruses have bipartite genomes consisting DNA-A and DNA-B that are encapsidated into separate virions. Individual virus species exist plants whitefly vectors as populations comprising both genome segments, can at different frequencies. Both segments required for infection, must be transmitted spread to occur. infected with cognate African cassava...
Cassava is a root crop important for global food security and the third biggest source of calories on African continent. production threatened by mosaic disease (CMD), which caused complex single-stranded DNA viruses (family: Geminiviridae , genus: Begomovirus ) that are transmitted sweet potato whitefly ( Bemisia tabaci ). Understanding dynamics different cassava begomovirus (CMB) species through time contextualizing trends. plants with CMD symptoms were sampled in Lake Victoria coastal...
Taro (Colocasia esculenta L. Schott) is an important crop for food and nutrition security, incomes, livelihood of people in developing countries. Its cultivation productivity have been limited mainly due to a lack quality planting materials. Therefore, this study developed effective micropropagation method two common taro varieties Kenya (Purple Wild Dasheen) using apical meristem derived from portions the corm base leaf petioles. This optimized 6-benzylaminopurine (BAP) indole-3-butyric...
Abstract Wastewater-based surveillance (WBS) has become a useful public health tool as an early warning system revealing emergence/re-emergence of pathogenic diseases and spread antimicrobial resistance (AMR). WBS is crucial in development rapid response increasing awareness to curb dangers associated with disease emergence antibiotic resistance. In this study, we characterized bacterial pathogens detected wastewater, their composition, relative abundance resistant genes (ARGs) from...
Purpose: Viral diseases cause severe yield losses and quality decline in crops worldwide. Despite their economic significance, the occurrence distribution of major viruses viroids infecting Taro Kenya remain poor, limiting development robust disease management strategies to mitigate spread. This study thus aimed identify as a basis for developing effective support prevention control viruses.
 Methodology: surveys sampling were conducted across nine Taro-growing counties with diverse...
