Abstract
Surveillance the epizootic situation is the main element of anti-epizootic measures to prevent the emergence and spread of avian influenza among poultry. Some subtypes of avian influenza can be zoonotic and therefore pose a serious threat to the poultry industry in Kazakhstan. In addition, there is a risk of the introduction of bird flu into the territory of our country from adjacent regions bordering Kazakhstan. Therefore, taking measures to prevent the introduction of the causative agent of this disease into the republic is an urgent task for the country's veterinary service to maintain welfare among birds. Avian influenza was monitored in seven regions that are located on the path of migratory birds and blood samples were taken from 624 chickens from 11 poultry farms and 9 private subsidiary farms. Further, ELISA was carried out to detect antibodies to the virus of this disease and 9 positive samples were detected. Then RT-PCR was performed with positive samples, but the samples showed a negative result. The birds may have had low pathogenic avian influenza. It is necessary to continue the annual epizootic monitoring, as well as to improve the sanitary-quarantine, anti-epizootic and diagnostic measures against avian influenza.
