Introduction On June 21, 2012, Mexico officially reported the presence of the highly pathogenic avian influenza (HPAI) virus subtype H7N3 in three commercial egg laying farms in the state of Jalisco. The affected birds showed clinical signs of ruffled feathers, lethargy, anorexia, prostration, depression, and acute death.1 The ages of the infected birds were 32, 72, 75, 84, and 94 weeks. To preve ...

Husam Bakri Thank you for your answer. I agree with you when you mention the post-vaccination reaction with La Sota when it gets complicated with Mycoplasma; however, and I apologize that insist, if we perform metaphylaxis against Mycoplasma, the protection conferred by La Sota gout to eye is superior to the Clone strain.

Husam Bakri I am interested in having your comment regarding the use of the strain La Sota gout to the eye, with the environmental conditions mentioned by Bahram Saeed.

I would suggest using the La Sota strain to vaccinate on outbreak. La Sota is more "aggressive" in the face of virulent challenges and offers a more solid immune response. I suggest that the application be drop to the eye because this allows us to ensure vaccination coverage closer to 100%

Rabah MerroucheI remind you that the Clone 30 strain is a "soft" Newcastle strain. Having 25% mortality is not synonymous with failure or failure to vaccinate, it is an expected behavior of the vaccine strain used, in the face of virulent challenges.

Muhammad Hassan In the respiratory processes is vitally important the use of live vaccines to generate Ig A and thereby neutralize the entry of pathogens, after its use is recommended the use of emulsified vaccines as buster. In the case of Newcastle, it is important to use several vaccinations with emulsified products to provide a solid immunity to the challenges.

Distinguished Mr. Wijaya Saputra What you describe about the oviduct was an injury that was observed with the H7N3 strain in Mexico. One of the managements that was successful in our egg birds, was the forced muda and the use of the emulsified vaccine. The change was initiated as soon as the virus was detected, IMMEDIATELY, if it was delayed, the management no longer worked. In our case, it was ...

Recall that Infectious Bronchitis is a virus enveloped by what good biosafety practices are very important, also with this we prevent the entry of other pathogens.

Udi Ashash We must remember that the importance of using vaccines with homologous strains against challenges of BIA is the prevention of the emergence of variant strains. Do not forget that the very evolution of this virus predisposes to genetic recombination.

Mustafa Ezat I appreciate your fast response.With a small flock, say 10,000 birds, with 80% protection, 8,000 birds would be protected and 2000 partially or unprotected, provided adequate vaccination coverage is achieved.These 2000 birds would be leading to the generation of new antigenic variants, this is the risk of not using homologous strains.
