部分原文报道如下:
Following the epidemiological surveillance activities carried out by the Veterinary Services of Mexico, avian influenza subtype H5N2 has been identified ; the intravenous pathogenicity test revealed that it corresponds to a low pathogenic avian influenza virus. The virus was isolated in a commercial farm of laying hens in the State of Sinaloa. The corresponding epidemiological investigation was initiated, including sampling in 4 industrial poultry farms and in 33 backyard poultry farms located in the 10-km zone around the outbreak, with a total of 720 samples of blood serum and tracheal and cloacal swabs, without detecting evidence of virus circulation. The production unit has been quarantined and a sanitary barrier has been set up. A humanely slaughter of birds programme will be launched even though it is a virus of low pathogenicity. Note by the OIE Animal Health Information Department: H5 and H7 avian influenza in its low pathogenic form in poultry is a notifiable disease as per Chapter 10.4. on avian influenza of the Terrestrial Animal Health Code (2015)。
