Abstract
Abstract Plasmodium vivax sporozoites are differenced by circumsporozoite protein. Studies on the circulation of P. vivax VK210 and P. vivax VK247 in anopheline mosquitoes are important to verify the adaptability of these parasites on mosquitoes in different locations and periods. This study aimed to describe and compare the distribution of these genotypes in anopheline mosquitoes from four states of the Brazilian Amazon. Epidemiological databases about CSP infections on mosquitoes from Pará (2000–2015), Amapá (2000–2010), Roraima (2000–2003 and 2009–2011) and Acre States (2012–2015) were used for analysis. A total of 895 specimens were found infected mainly by P. vivax VK210. We showed that the distribution of P. vivax VK247 changed over time in the main malaria vectors on the Brazilian Amazon. We note that A. darlingi was abundant in certain localities while A. albitarsis s.l. in anothers, which highlights the importance of entomological studies for the control of human malaria.
