The inappropriate use of vaccination calendars with strains that do not exist in the wild leads to antigenic variants.In short: variants arise because those who administer vaccines with non-existent strains provide material for the virus to recombine.

RNA genome viruses, such as the avian infectious bronchitis virus, lack a proofreading mechanism during their replication. This means that, unlike DNA organisms, which have enzymes that can correct errors in their genetic material, RNA viruses tend to accumulate mutations more rapidly either through point mutation phenomena or recombination. This high rate of antigenic changes can influence their ...

Avian Influenza Virus (AIV) poses a significant threat to both avian populations and human health due to its potential for zoonotic transmission. The emergence of highly pathogenic strains necessitates the development of innovative control strategies. This abstract presents a comprehensive overview of the potential of CRISPR-based technologies, Quorum Sensing (QS) systems, and the application of t ...

The experience. The silent entry of the Avian Influenza (AI) virus into Mexican territory, for the experience. In March 1994, a Low Pathogenicity (LP) subtype H5N2 virus entered Mexico stealthily and spread fast in poultry districts. The virus was common in flocks when discovered. It became an HP virus in December, jeopardizing food security. A biological was developed using biosafety. December 19 ...

1. IntroductionThe male breeding broiler is the bird used to produce a fertile egg from which the future broiler will be fattened to obtain meat. The importance of the rooster lies in the dissemination of genetic progress to obtain, in its progeny, large muscle masses because during its reproductive stage it is responsible for the fertilization of 1000 to 2000 eggs [1].Currently, due to the geneti ...

I appreciate your comment.
According to the OIE Terrestrial Manual, it prevents the presence of antibodies to AI by vaccination, which means that it can be vaccinated. It is recommended not to vaccinate so that the country does not lose the status of free, however, as mentioned in a previous comment (June 1) , the infection entered Mexico by a very important poultry area (7 ...

I thank you for the valuable information you share with us.
The TNF response is given by the infection. When the number of receptors decreases by the molt, the antigenic load decreases, which can be controlled by the immune response induced by the vaccination.

We appreciate your kind words.
Regarding his approach. Indeed that is the theory that we have. however, the bird will survive as long as it has an adequate vaccination schedule. The idea of the pelecha is to protect the reproductive tract of the bird, the vaccine is the one that protects the life of the bird.
