10. Molecular detection of flaviviruses and alphaviruses in mosquitoes (Diptera: Culicidae) from coastal ecosystems in the Colombian Caribbean
Arboviruses belonging to the genera Flavivirus and Alphavirus were detected in mosquitoes in a rural area of San Bernardo del Viento (Córdoba, Colombia). A total of 22,180 mosquitoes were collected, sorted into 2,102 pools, and tested by generic/nested reverse transcription-polymerase chain reaction.

11. Potent inhibition of Western Equine Encephalitis virus by a fraction rich in flavonoids and phenolic acids obtained from Achyrocline satureioides
ABSTRACT Achyrocline satureioides (Lam.) DC. Asteraceae, ‘marcela del campo', possess several pharmacological properties. Previously we reported antiviral activity of an aqueous extract of A. satureioides against an alphavirus, Western Equine Encephalitis virus. Alphaviruses are highly virulent pathogens which cause encephalitis in humans and equines. Ther
