Malaria parasites of the genus Polychromophilus commonly infect vespertilionid and miniopterid bats, and are transmitted by bat flies (Nycteribiidae). While Polychromophilus murinus has been recorded sporadically in Europe, its host range, distribution and phylogeographic structure have not been explored. Here we investigate the prevalence and genetic diversity of P.

Selectivity in Buttress Drumming Tree Properties Among Chimpanzees (Pan troglodytes schweinfurthii) of the Waibira Community in Budongo Forest, Uganda.

Wild chimpanzees drum on tree buttresses during dominance displays and travel, generating low-frequency sounds that are audible over distances of more than 1 km. Western chimpanzees (Pan troglodytes verus) in the Nimba Mountains of Guinea selectively choose trees and buttresses when drumming, potentially based on their resonant properties, suggesting that these chimpanzees are optimizing their drumming signals. We investigated whether male eastern chimpanzees (Pan troglodytes schweinfurthii) from the Waibira community in the Budongo Forest, Uganda, also show preferences in tree and buttress choice, exploring whether selectivity is a species-wide feature.

Barriers and facilitators to interprofessional simulation-based learning in a Ugandan medical school: a qualitative study.

Background: Although Interprofessional Education (IPE) is an important component of medical education, it has only recently come under consideration in Sub-Saharan Africa. IPE occurs when two or more professions learn from, about and with each other regarding effective collaboration and the improvement of health outcomes. Current academic programs focus more on traditional approaches to training physicians, pharmacists, respiratory therapists, physiotherapists and nurses like they were independent entities.

Molecular phenotypes of critical illness confer prognostic and biological enrichment in sub-Saharan Africa: a prospective cohort study from Uganda.

The generalisability of critical illness molecular phenotypes to low- and middle-income countries (LMICs) is unknown. We show that molecular phenotypes derived in high-income countries (hyperinflammatory and hypoinflammatory, reactive and uninflamed) stratify sepsis patients in Uganda by physiological severity, mortality risk and dysregulation of key pathobiological domains. A classifier model including data available at the LMIC bedside modestly discriminated phenotype assignment (area under the receiver operating characteristic curve (AUROC) 0.

Pre-HIV α4β7hi CD4+ T cells and HIV risk among heterosexual individuals in Africa.

Background: CD4+ T cells expressing α4β7 are optimal targets for HIV infections, with higher pre-HIV α4β7hi expression linked to increased HIV acquisition and progression in South African women. However, similar associations were not observed in men who have sex with men (MSM) or people who inject drugs (PWID) in the Americas, indicating need for further research.

Methods: This retrospective case-control study enrolled heterosexual men and women from South Africa (HIV Vaccine Trials Network; HVTN 503) and East Africa (Partners Pre-Exposure Prophylaxis/Couples' Observational Study; PP/COS), quantifying α4β7 expression on CD4+ T cells as a predictor of subsequent HIV risk using flow cytometry analyses.
