[TD]Se recibi? la notificaci?n de mortalidad de aves de combate en un predio en Guanajuato; el propietario coment? haber participado en una competencia recientemente. El aislamiento del virus en la muestra de Quer?taro se obtuvo tras la notificaci?n de un productor, que se ubica a 7 km del foco reportado anteriormente en ese estado. Se trabaja en pruebas complementarias como IPIV y secuenciaci?n. En ambos casos, se implementaron actividades contraepid?micas como cuarentena de los predios y sacrificio de todas las aves; y por prevenci?n, se establecieron un ?rea focal de 3 km y una perifocal de 10 km, en donde se est? llevando a cabo el muestreo correspondiente para comprobar la ausencia de enfermedad. El Servicio Nacional Veterinario seguir? con la vigilancia epidemiol?gica e informar? a la OIE de cualquier nuevo caso.[/TD]
