Mouse Experiments Demonstrate Differential Pathogenicity And Virulence Of Trypanosoma Brucei Rhodesiense Strains, Limo William Kipkorir, Thuita Kibuthu John, Orindi Benedict Owino, Oidho John, Shivairo Robert, Masiga Daniel, Adung'a Vincent Owino

All Peer-Reviewed Publications

Trypanosoma brucei rhodesiense is the causative agent for Rhodesian human African trypanosomiasis. The disease is considered acute, but varying clinical outcomes including chronic infections have been observed. The basis for these different clinical manifestations is thought to be associated with a combination of parasite and host factors. In the current study, Trypanosoma brucei rhodesiense strains responsible for varying infection outcomes were sought using mouse model. Clinical rHAT parasite isolates were subjected to PCR tests to confirm presence of the serum resistance associated (SRA) gene. Thereafter, four T. b. rhodesiense isolates were subjected to a comparative pathogenicity study using female Swiss …

How Is Organic Farming Performing Agronomically And Economically In Sub-Saharan Africa?, Christian Schader, Anja Heidenreich, Irene Kadzere, Irene Egyir, Anne Muriuki, Joseph Bandanaa, Joseph Clottey, John Ndungu, Christian Grovermann, Gianna Lazzarini, Johan Blockeel, Christian Borgemeister, Adrian Muller, Fred Kabi, Komi Fiaboe, Noah Adamtey, Beate Huber, Urs Niggli, Matthias Stolze

All Peer-Reviewed Publications

The potential of organic agriculture and agroecological approaches for improving food security in Africa is a controversial topic in global discussions. While there is a number of meta-analyses on the environmental, agronomic and financial performance of organic farming, most of the underlying data stems from on-station field trials from temperate regions. Data from sub-Sahara Africa in particular, as well as detailed real-farm data is scarce. How organic farming is implemented in sub-Saharan Africa and how it performs in a smallholder context remains poorly understood. We applied a novel observational two-factorial research design, which allowed to evaluate the impacts of i) …

Optimizing Interaction Between Crop Residues And Inorganic N Under Zero Tillage Systems In Sub-Humid Region Of Kenya, Kinyua Michael, Mucheru Muna Monicah, Bolo Peter, Kihara Job

All Peer-Reviewed Publications

Conservation agriculture practices involving zero tillage and residue retention are promising nutrient management strategies for soil health restoration. Despite their potential positive impact on soil fertility, improved crop yields and increased revenues for smallholder farmers; their effect on nitrogen inputs and crop growth is not clearly understood. This may limit their potential as a nutrient management strategy that may remedy soil degradation and boost crop yields for farmers. This study investigated how different tillage practices, crop residues and inorganic nitrogen (N) options affect maize production, soil fertility and economics of smallholder farming systems. The study was conducted in a short-term …

Molecular Characterization Of Trypanosoma Vivax In Tsetse Flies Confirms The Presence Of The Virulent Tvv4 Genotype In Kenya: Potential Implications For The Control Of Trypanosomiasis In Shimba Hills, Faith I. Ebhodaghe, Armanda D.S. Bastos, Kevin O. Kidambasi, Shewit Kalayou, Daniel K. Masiga, Michael N. Okal

All Peer-Reviewed Publications

Trypanosoma vivax is a vector-borne protozoan parasite of livestock endemic to Africa and South America. To date, fifteen genotypes of the parasite have been described in vertebrate and insect hosts in East Africa. However, information regarding T. vivax diversity remains limited in many endemic countries in the sub-region, including Kenya. Such information could deepen insight into the local epidemiology of animal trypanosomiasis in Shimba Hills, a wildlife area in southeast Kenya where T. vivax is endemic and infects livestock. We employed two-gene conventional-PCR-sequencing and phylogenetic analysis to characterize T. vivax genotypes in tsetse flies collected between November 2018 and September …

Field Testing Of A Putative Larviposition Pheromone For The Tsetse Fly Glossina M. Morsitans Westwood, J. W. Hargrove, J. Van Sickle, R. K. Saini

All Peer-Reviewed Publications

Under laboratory conditions, the alkane hydrocarbon n-pentadecane attracts gravid female tsetse (Glossina morsitans morsitans Westwood) to potential larviposition sites. We describe field-testing of this chemical, which is the first such test for any putative tsetse larviposition pheromone. We replicated randomised block experiments at 11 sites near Rekomitjie Research Station, Zambezi Valley, Zimbabwe. Each site comprised a cluster of four artificial warthog burrows constructed from 200-litre steel drums. We placed six trays, filled with sand and covered with leaf litter, inside each burrow. Both species of tsetse inhabiting this region entered these artificial burrows and deposited 1282 pupae in the trays …

Evaluating Livestock Farmers Knowledge, Beliefs, And Management Of Arboviral Diseases In Kenya: A Multivariate Fractional Probit Approach, Paul Nyamweya Nyangau, Jonathan Makau Nzuma, Patrick Irungu, Menale Kassie

All Peer-Reviewed Publications

Globally, arthropod-borne virus (arbovirus) infections continue to pose substantial threats to public health and economic development, especially in developing countries. In Kenya, although arboviral diseases (ADs) are largely endemic, little is known about the factors influencing livestock farmers’ knowledge, beliefs, and management (KBM) of the three major ADs: Rift Valley fever (RVF), dengue fever and chikungunya fever. This study evaluates the drivers of livestock farmers’ KBM of ADs from a sample of 629 respondents selected using a three-stage sampling procedure in Kenya’s three hotspot counties of Baringo, Kwale, and Kilifi. A multivariate fractional probit model was used to assess the …

Paenibacillus Polymyxa Causes Yellow Withered Spot Disease In Dracaena Trifasciata In The South Of China, Baochun Lai, Yongwen Lin, Komivi Senyo Akutse, Ruiqing Dai

All Peer-Reviewed Publications

Mother-in-law’s tongue, Dracaena (Sansevieria) trifasciata S. is an ornamental houseplant of Asparagaceae family and native to tropical western Africa and southern Asia. Following a yellow withered spot symptom observed on up to one third of D. trifasciata plants at the field, a new bacterium pathogen was discovered for the first time in South of China. This pathogen was isolated from the early irregular yellow spot and its pathogenicity to the host plant was confirmed through artificial infection. Through both morphological characteristics and molecular DNA sequences using 16S rDNA and three housekeeping genes, the pathogen was identified and characterized as Paenibacillus …

All Peer-Reviewed Publications

The 4th Global Food Security conference highlighted four major developments: the shift from food security to food systems; a focus on diets and consumption patterns; the importance of unknown futures and inherent uncertainties and risks; and the central role of multi-level connections between local- and global-oriented research. These shifts highlight the importance for research to contribute to dialogue and collective intelligence through evidence-based brokerage, and to move beyond polarization of debates. These shifts also call for the involvement of scientists in multi-stakeholder arrangements to strengthen innovation and learning at different levels, and for their participation in foresight studies to help …

Estimating Maize Lethal Necrosis (Mln) Severity In Kenya Using Multispectral High-Resolution Data, Kyalo Richard, Elfatih M. Abdel-Rahman, Sevgan Subramanian, Johnson O. Nyasani, Michael Thiel, Hossein J. Jozani, Christian Borgemeister, Bester T. Mudereri, Tobias Landmann

All Peer-Reviewed Publications

Maize lethal necrosis (MLN) is a severe disease in maize that significantly reduces yields by up to 90% in maize-growing regions such as Kenya and other countries in Africa. The disease causes chlorotic mottling of leaves and severe stunting which leads to plant death. The spread of MLN in the maize-growing regions of Kenya has intensified since the first outbreak was reported in September 2011. In this study, the RapidEye (5 m) imagery was combined with field-based data of MLN severity to map three MLN severity levels in Bomet County, Kenya. Two RapidEye images were acquired during maize stem elongation …

Cost–Benefit Analysis Of Improved Light Trap For Harvesting The Edible Grasshopper, Ruspolia Differens (Orthoptera: Tettigoniidae): Evidence From Uganda, Francis Sengendo, Sevgan Subramanian, Michael Kidoido, Moses Chemurot, Chrysantus Tanga, James Peter Egonyu

All Peer-Reviewed Publications

Recent evidence has shown that improved light traps comprising modified drums and light emitting diode bulbs are more efficient and safer in mass trapping of wild swarms of Ruspolia differens compared to mercury light traps with open-ended drums commonly used in Uganda. However, financial analysis of the improved traps had not yet been conducted prior to this study. Here, we carried out a cost–benefit analysis of the improved trap compared to the existing trapping technique. A pre-tested questionnaire was used to collect data on the demographic characteristics, revenue, capital expenditures and operating costs of the current trapping method from 30 …

Once Upon An American Dream: What The American Dream Means To Different People

Symposium of Student Scholars

One of the most prominent ethoses of the United States of America is that of the “American Dream.” While James Truslow Adams was the person to coin the term “American Dream,” the concept dates back to the Declaration of Independence, which states that all men have the right to “life, liberty, and the pursuit of happiness.” While the “American Dream” can be thought of as a single concrete goal, Ştiuliuc argues, however, that “it constitutes a cultural narrative with manifold implications in the multiple and distinct immigrant stories that created America” (2011:364). In order to determine the validity of this …

How Theatre Produced By Autistic People Dismantles The Medical Model Of Disability, Ira Eidle

Symposium of Student Scholars

Autism is a neurodevelopmental disability that has a long history of being misunderstood. Said misunderstandings have led to falsehoods about autism and autistic people. The stigma surrounding autism encourages non-autistic people to see themselves as the best advocates for autism, leading to non-autistic people speaking over autistic people constantly. This has come to be known as the medical model of disability. Most autistic people do not consider autism to be a mental illness or disorder. (Kupferstein 2019) That is why when autistic people become informed on these aspects and band together, those misunderstandings can be mitigated. One such way is …

Amazon: A Maze Through China - An International Marketing Case Study, Hanane Goubil

Symposium of Student Scholars

Amazon is an e-commerce technology company best known for its fast delivering time and for being one of the tops of the big four technology companies in the United States. Despite its success in the U.S. and several countries abroad, it has struggled to succeed in China since 2004 where Alibaba and JD.com control 82% of the market. This is due to Amazon failing to compete with Alibaba and neglecting to acclimatize their online offers to appease Chinese customers’ preferences. An example of this is that Alibaba has its own payment system called Alipay, while Amazon had yet to include …
