Abstract
A sero-epidemiological survey was undertaken to detect the circulation of arboviruses in free-living non-human primates. Blood samples were obtained from 16 non-human primates (13 Sapajus spp. and three Alouatta caraya) that were captured using terrestrial traps and anesthetic darts in woodland regions in the municipalities of Campo Grande, Aquidauana, Jardim, Miranda and Corumbá in the State of Mato Grosso do Sul, Brazil. The samples were sent to the Instituto Evandro Chagas (IEC) in Ananindeua, Pará, Brazil, to detect antibodies against 19 species of arboviruses using a hemagglutination inhibition test (HI). Of the 16 primates investigated in the present study, five (31.2%) were serologically positive for an arbovirus. Of these five, two (12.5%) exhibited antibodies to the Flavivirus genus, one (6.2%) exhibited a monotypic reaction to Cacipacoré virus, one (6.2%) was associated with Mayaro virus, and one (6.2%) was positive for Oropouche virus. Based on the positive serology observed in the present study, it was possible to conclude that arboviruses circulate among free-living primates. The viruses in the areas studied might have been introduced by infected humans or by primates from endemic or enzootic areas. Studies of this nature, as well as efficient and continuous surveillance programs, are needed to monitor viral activities in endemic and enzootic regions.
Highlights
A sero-epidemiological survey was undertaken to detect the circulation of arboviruses in free-living non-human primates
Two primates exhibited antibodies to viruses belonging to the genus Flavivirus, one exhibited a monotypic reaction to Cacipacoré virus, one exhibited a reaction to Mayaro virus (MAYV), and one (6.2 %) exhibited a reaction to Oropouche virus (OROV) (Table 2 and Table 3)
The results found in the present study were similar to results previously reported for the municipality of Bonito (State of Mato Grosso do Sul), in which 17 (48.5%) animals exhibited antibodies to arboviruses of the genus Alphavirus and Flavivirus, as well as monotypic reactions to Mayaro and Oropouche viruses
Summary
A sero-epidemiological survey was undertaken to detect the circulation of arboviruses in free-living non-human primates. The most commonly affected people are those who maintain close contact with wild environments where ecological niches of arbovirus exist[2]. In these environments, arboviruses can cause meningitis and diseases of the central nervous system, as seen for infections with St. Louis encephalitis virus (SLEV), Rocio virus (ROCV), eastern equine encephalitis virus (EEEV) and western equine encephalitis virus (WEEV)[1]. Arboviruses contain genomes made up of ribonucleic acid (RNA) that is either segmented or non-segmented[3] These viruses are classified into five principal families according to their antigenic properties and physicochemical characteristics: Bunyaviridae, Flaviviridae, Reoviridae, Togaviridae and Rhabdoviridae[1]
