Repeated horizontal acquisition of lagriamide-producing symbionts in Lagriinae beetles.

Microbial symbionts associate with multicellular organisms on a continuum from facultative associations to mutual codependency. In the oldest intracellular symbioses there is exclusive vertical symbiont transmission, and co-diversification of symbiotic partners over millions of years. Such symbionts often undergo genome reduction due to low effective population sizes, frequent population bottlenecks, and reduced purifying selection.

Hard ticks (Ixodida: Ixodidae) in the Colombian Caribbean harbor the Jingmen tick virus: an emerging arbovirus of public health concern.

Background: Ticks are obligate hematophagous ectoparasites involved in transmitting viruses of public health importance. The objective of this work was to identify the Jingmen tick virus in hard ticks from the Colombian Caribbean, an arbovirus of importance for public health.

Methods: Ticks were collected in rural areas of Córdoba and Cesar, Colombia.

Critical route for development of medical student leadership competencies in 35 Pan American Health Organization member states: A scoping review and thematic analysis.

The Pan American Health Organization has been committed to training physicians in leadership competencies since 2008. However, four reviews on teaching leadership using competency-based education in undergraduate medical education (UME) identified only two of 35 MS: Canada and the USA. Previous reviews did not use a systemic approach or qualitative methodology to explore factors influencing leadership education.
