The serologic survey and the confirmatory molecular diagnostic suggested evidence of a fairly presence of ILT infection in the main poultry farms of Ecuador. The current work highlights the need to apply a control program of ILT based on vaccination and standard biosecurity measures in the poultry farms of Ecuador.
