Patchy Parasitized Skin Governs Leishmania donovani Transmission to Sand Flies

Trends Parasitol. 2017 Oct;33(10):748-750. doi: 10.1016/j.pt.2017.08.004. Epub 2017 Aug 31.

Abstract

Doehl et al. have combined empirical data with computer simulation to demonstrate that RAG-2 mice intravenously infected with Leishmania donovani form heterogeneous skin parasite patches that govern infectiousness to sand flies. This model provides a much-needed tool to explore the relevance of asymptomatic and symptomatic visceral leishmaniasis patients as infection reservoirs.

Keywords: Leishmania donovani; anthroponotic visceral leishmaniasis; bite site; outward transmission; skin parasite patches; vector sand flies.
