A spatial genetics approach to inform vector control of tsetse flies (Glossina fuscipes fuscipes) in Northern Uganda

Saarman, Norah; Burak, Mary; Opiro, Robert; Hyseni, Chaz; Echodu, Richard; Dion, Kirstin; Opiyo, Elizabeth A.; Dunn, Augustine W.; Amatulli, Giuseppe; Aksoy, Serap; Caccone, Adalgisa (Ecology and evolution, 2018)

Tsetse flies (genus Glossina) are the only vector for the parasitic trypanosomes responsible for sleeping sickness and nagana across sub-Saharan Africa. In Uganda, the tsetse fly Glossina fuscipes fuscipes is responsible ...

Esperanza Window Traps for the collection of anthropophilic blackflies (Diptera: Simuliidae) in Uganda and Tanzania

Hendy, Adam; Sluydts, Vincent; Tushar, Taylor; De Witte, Jacobus; Odonga, Patrick; Loum, Denis; Nyaraga, Michael; Lakwo, Thomson; Dujardin, Jean-Claude; Post, Rory; Kalinga, Akili; Echodu, Richard (PLoS neglected tropical diseases, 2017)

There is an increasing need to evaluate the impact of chemotherapeutic and vector-based interventions as onchocerciasis affected countries work towards eliminating the disease. The Esperanza Window Trap (EWT) provides a ...

Analysis of the gut-specific microbiome from field-captured tsetse flies, and its potential relevance to host trypanosome vector competence

Griffith, Bridget C.; Weiss, Brian L.; Aksoy, Emre; Mireji, Paul O.; Auma, Joana E.; Wamwiri, Florence N.; Echodu, Richard; Murilla, Grace; Aksoy, Serap (BMC microbiology, 2018)

The tsetse fly (Glossina sp.) midgut is colonized by maternally transmitted and environmentally acquired bacteria. Additionally, the midgut serves as a niche in which pathogenic African trypanosomes reside within infected ...

Analysis of Multiple Tsetse Fly Populations in Uganda Reveals Limited Diversity and Species-Specific Gut Microbiota

Aksoy, Emre; Telleria, Erich L.; Echodu, Richard; Wu, Yineng; Okedi, Loyce M.; Weiss, Brian L.; Aksoy, Serap; Caccone, Adalgisa (Applied and Environmental Microbiology, 2014)

The invertebrate microbiome contributes to multiple aspects of host physiology, including nutrient supplementation and immune maturation processes. We identified and compared gut microbial abundance and diversity in natural ...

Evidence of temporal stability in allelic and mitochondrial haplotype diversity in populations of Glossina fuscipes fuscipes (Diptera: Glossinidae) in northern Uganda

Opiro, Robert; Saarman, Norah P.; Echodu, Richard; Opiyo, Elizabeth A.; Dion, Kirstin; Halyard, Alexis; Aksoy, Serap; Caccone, Adalgisa (Parasites & Vectors, 2016)

Glossina fuscipes fuscipes is a tsetse species of high economic importance in Uganda where it is responsible for transmitting animal African trypanosomiasis (AAT) and both the chronic and acute forms of human African ...

Genetically Distinct Glossina fuscipes fuscipes Populations in the Lake Kyoga Region of Uganda and Its Relevance for Human African Trypanosomiasis

Echodu, Richard; Sistrom, Mark; Hyseni, Chaz; Enyaru, John; Okedi, Loyce; Aksoy, Serap; Caccone, Adalgisa (BioMed research international, 2013)

Tsetse flies (Glossina spp.) are the sole vectors of Trypanosoma brucei—the agent of human (HAT) and animal (AAT) trypanosomiasis. Glossina fuscipes fuscipes (Gff ) is the main vector species in Uganda—the only country ...

The population genomics of multiple tsetse fly (Glossina fuscipes fuscipes) admixture zones in Uganda

Saarman, Norah P.; Opiro, Robert; Hyseni, Chaz; Echodu, Richard; Opiyo, Elizabeth A.; Dion, Kirstin; Johnson, Thomas; Aksoy, Serap; Caccone, Adalgisa (Saarman, N. P., Opiro, R., Hyseni, C., Echodu, R., Opiyo, E. A., Dion, K., ... & Caccone, A. (2019). The population genomics of multiple tsetse fly (Glossina fuscipes fuscipes) admixture zones in Uganda. Molecular ecology, 28(1), 66-85., 2019)

Understanding the mechanisms that enforce, maintain or reverse the process of speciation is an important challenge in evolutionary biology. This study investigates the patterns of divergence and discusses the processes ...

Spatio-temporal distribution of Spiroplasma infections in the tsetse fly (Glossina fuscipes fuscipes) in northern Uganda

Schneider, Daniela I.; Saarman, Norah; Onyango, Maria G.; Hyseni, Chaz; Opiro, Robert; Echodu, Richard; O’Neill, Michelle; Bloch, Danielle; Vigneron, Aure´lien; Johnson, T.
