Summary
Arbovirus surveillance in Surinam identified Guamá and Catú viruses. These Guamá-group viruses were isolated from mosquitoes in savannah and coastal regions, contributing to arbovirus research.
Area of Science:
- Arbovirology
- Medical Entomology
- Virology
Background:
- Arboviruses pose significant public health threats globally.
- Entomological surveys are crucial for understanding arbovirus transmission dynamics.
- Surinam's diverse ecosystems harbor potential arbovirus vectors.
Purpose of the Study:
- To further characterize Guamá-group arboviruses isolated during entomological surveys in Surinam.
- To identify specific viral strains and their mosquito hosts.
- To contribute to the ongoing surveillance of arboviruses in the region.
Main Methods:
- Mosquitoes were collected during entomological surveys in Surinam's savannah and coastal areas (October 1972–December 1973).
- Arboviruses were isolated from mosquito pools.
- Complement-fixation and neutralization tests in mice were used for viral typing against Guamá, Bimití, Catú, and Moyú reference viruses.
Main Results:
- Guamá and Catú virus strains were identified among the isolated Guamá-group viruses.
- Four strains of Guamá virus were isolated from *Coquillettidia venezuelensis* in the coastal area.
- Four strains of Catú virus were isolated from *Culex portesi* in the savannah area.
Conclusions:
- The study successfully identified and typed Guamá and Catú arboviruses in Surinam.
- Specific mosquito species, *Coquillettidia venezuelensis* and *Culex portesi*, were implicated as vectors.
- These findings enhance the understanding of arbovirus epidemiology in Surinam and inform future control strategies.
