Ethical considerations in global HIV phylogenetic research

Phylogenetic analysis of pathogens is an increasingly powerful way to reduce the spread of epidemics, including HIV. As a result, phylogenetic approaches are becoming embedded in public health and research programmes, as well as outbreak responses, presenting unique ethical, legal, and social issues that are not adequately addressed by existing bioethics literature. We formed a […]

Laboratory methods in molecular epidemiology: Viral infections

Viruses, which are the most abundant biological entities on the planet, have been regarded as the “dark matter” of biology in the sense that despite their ubiquity and frequent presence in large numbers, their detection and analysis are not always straightforward. The majority of them are very small (falling under the limit of 0.5 μm), […]

Multiple Class i and Class II Haemophilus ducreyi Strains Cause Cutaneous Ulcers in Children on an Endemic Island

BACKGROUND: Together with Treponema pallidum subspecies pertenue, Haemophilus ducreyi is a major cause of exudative cutaneous ulcers (CUs) in children. For H. ducreyi, both class I and class II strains, asymptomatic colonization, and environmental reservoirs have been found in endemic regions, but the epidemiology of this infection is unknown. METHODS: Based on published whole-genome sequences […]

Insights on Mycobacterium leprae Efflux Pumps and Their Implications in Drug Resistance and Virulence

Drug resistance in Mycobacterium leprae is assumed to be due to genetic alterations in the drug targets and reduced cell wall permeability. However, as observed in Mycobacterium tuberculosis, drug resistance may also result from the overactivity of efflux systems, which is mostly unexplored. In this perspective, we discuss known efflux pumps involved in M. tuberculosis drug resistance and virulence and […]
