Chickens stand sentinel against mosquito-borne disease in Florida
Antibodies in the birds reveal when certain viral pathogens are being transmitted locally
For 40 years, they’ve held the front line in Florida’s fight against mosquito-borne diseases. And it turns out that the chickens standing sentinel in cities, marshes, woodlands and residential backyards are clucking good at their job.
Last year, chickens in 268 coops in over a third of Florida’s counties provided scientists weekly blood samples that revealed whether the birds had been bitten by mosquitoes carrying West Nile virus or the Eastern equine encephalitis or St. Louis encephalitis viruses.
