The behavior of bronchitis in young birds (1 to 7 days of age) is a characteristic caseous plug; In the case that I mention is the presence of caseous plug in birds in production, but here the interesting thing is the respiratory complex that occurs in which are involved: Mycoplasma, low pathogenic AI and IB.

I want to share with you the experience we have had with the IB virus. When IB + IA of low + Mycoplasma is present, these three agents generate a very important synergy that complicate the respiratory pictures. The association Mycoplasma with low pathogenic AI is important, but when IB is involved, the picture becomes very aggressive, especially, cases of caseous plugs are present and the percenta ...

Distinguished Dr. We appreciate your valuable comments. In fact, the behavior of the percentage of mortality in the flock was the one we mentioned in the paper, is a fact that seemed very important given the characteristics of the virus in question. Regarding your question about IB variants we can not assure you if they were present or absent because we could not manipulate samples to perform sero ...

Introduction In June 2012, a highly pathogenic avian influenza (HPAI) virus, subtype H7N3, was identified as the cause of a severe disease outbreak in commercial layer farms in the Western State of Jalisco. Approximately 22.4 million birds died due to the infection or to the preventive stamping out of neighboring farms.6 On July 26, 2012, a national vaccination program was established using an ...

Thank you for your question Dr Jignesh Barot. According to what we have observed, as the virus distances itself in relation to its ancestor, due to the antigenic changes that it suffers, the recognition of the standard antisera towards the virus is no longer effective and the test gives us false Negative results. Hence the importance of updating the antisera.

Thank you for your congratulations. Your question is very good! Dr. Jignesh Barot When the AI virus is antigenically disassociated even though it is the same subtype, the standard antisera no longer adequately recognize the virus that presents antigenic variation and that causes the difference reported with the HI technique.

In relation to the comment made on the presence of AI in South America, the information given by the Brazilian authorities in a presentation that I had in that country, was that the migratory routes of the Anatides did not reach so far south of the continent.

Good morning Dr, I appreciate your comments. At the moment we are developing the project to analyze the viruses that have been reported to the OIE and whose sequence is available in the information banks. The results could give us a lot of information regarding what is happening.

  Background Avian Influenza (AI) virus belongs to the Orthomyxoviridae family, Influenzavirus A genus. This virus possesses eight segments of single-stranded RNA genome. Two of these segments encode for two important membrane glycoproteins, hemagglutinin (HA) and neuraminidase (NA) [1], that play a key role during cellular infection. These two proteins are used for virus subtype classifica ...
