Avian influenza

Bird flu (avian flu or bird flu) is an infectious disease that affects birds caused by type A virus of the family Orthomyxoviridae, genus Influenzavirus A. Infection with these viruses occurs naturally and is the main reservoir water birds, can be carriers of the pathogen in their intestines but usually do not develop the disease. Bird flu is very contagious among birds and can infect and sicken domestic species, including chickens, ducks and turkeys. The virus can spread through saliva, nasal secretions and faeces.
Depending on the age, type of bird and environmental factors, the disease varies between sudden death with few signs or no signs patent, to a more characteristic disease with respiratory symptoms, excessive lacrimation, sinusitis, edema in the head, cyanosis of the skin not covered with feathers, and diarrhea.
The diagnosis of the disease can be achieved by molecular techniques that allow the determination of the virulence of the virus. The testing of serum from suspect birds using antibody detection methods can complement the diagnosis, although these methods are not suitable for detailed identification.
Bioingentech can detect avian influenza virus using the following techniques, supported by the World Organisation for Animal Health (OIE):
