New tools and insights to assist with the molecular identification of Simulium guianense s.l., main Onchocerca volvulus vector within the highland areas of the Amazonia onchocerciasis focus.
Crainey JL, Mattos-Glória A, Hamada N, Luz SL. Crainey JL, et al. Acta Trop. 2014 Mar;131:47-55. doi: 10.1016/j.actatropica.2013.10.019. Epub 2013 Nov 4. Acta Trop. 2014. PMID: 24200838
In the hyperendemic highland areas of the Amazonia focus, Simulium guianense s.l. Wise are the most important vectors of the disease. Populations of S. guianense s.l. are, however, known to vary in their cytogenetics and in a range of behaviours, including in their …
