Abstract

Seroprevalence of selected flaviviruses in free-living and captive capuchin monkeys in the state of Pernambuco, Brazil.

Abstract

Mosquito-borne diseases such as dengue, yellow fever and, more recently, Chikungunya virus (CHIKV) and Zika virus (ZIKV) have a great impact in the public health. In addition, the presence of such viruses might have an impact on wild animal conservation as well as their possible role as animal reservoir. Here, we performed a serological survey searching for antibodies against a panel of flaviviruses [ZIKV, Dengue virus (DENV), Yellow Fever virus (YFV), West Nile virus (WNV), Saint Louis Encephalitis virus (SLEV), Ilheus virus (ILHV) and Rocio virus (ROCV)] using plaque reduction neutralization test (PRNT90) in both free-ranging and captive capuchin monkeys (Sapajus flavius and Sapajus libidinosus). Captive and free-living monkeys were sampled between June 2015 and January 2016 in the state of Pernambuco, including in the border with State of Paraíba, the epicentre of the ZIKV epidemics in Brazil. We have found neutralizing antibodies for ZIKV, DENV-1, DENV-2, DENV-3, DENV-4, YFV, ILHV and SLEV in both S. flavius and S. libidinosus samples. No positives samples were found for ROCV and WNV. Our results suggest that these flaviviruses might be circulating in capuchin monkey in the studied region. The possible presence of these viruses represents a risk for public health, as well as for animal conservation, especially for S. flavius which is a critically endangered species, facing high risk of extinction.
