Genome of human influenza is a rapid process of biological innovation
When examined from the standpoint biological flu viruses, "the first thing that strikes one is that we are contending with a biological entity that is a chimera, that is, has different origins, not only have a pig virus components , birds and humans that may affect them, but we also know that there are cases of humans infected pigs, "said Lazcano

Mexico City .- The virus causing the influenza A/H1N1 human evolution with an enormous speed, so please be alert to the resistance that can develop the drugs, said Antonio Lazcano, a researcher at the Faculty of Sciences (FC ), Universidad Nacional Autonoma de Mexico (UNAM).
Recommended to the health sector to provide immediate care to patients and study in detecting a mutation of the virus and showing resistance to drugs.
During the round table and A/H1N1 virus epidemic, an evolutionary analysis, reported that academic experts have studied these strains in cases that were filed in Mexico with the purpose of knowing how it has evolved microorganism and estimate where might.
Lazcano said the last two PRI governments and PAN have "dismantled" key institutions for the country given the lack of interest and resources.
Destruction of facilities
"The country has been dismantled research, the PRI and PAN have destroyed the centers of excellence. For example, a few years ago the Mexican Petroleum Institute was a landmark, the Postgraduate School is now on strike, but at the time generated by the country's agricultural research. The Mexican state, with society as a passive accomplice, has dismantled a number of key institutions to Mexico. "
During his presentation, the researcher conducted an analysis of the FC new pathogen from a biological and not epidemiological. Indicated that the human influenza virus is the "overwhelming show of Darwinian vision. "When studying the genome of this virus demonstrated a biological process of innovation. A/H1N1 virus is the result of the combination of which, in turn, are the result of another combination."
Indicated that this pathogen is associated with ribonucleic acid (RNA) of the body, so its evolution is at least a million times faster than if it were a virus DNA.
Lazcano took stock of the level of infectious diseases of various types of viruses among humans. Emphasized that rabies is transmitted from mammal to human, but "on rare occasions an infected man to another." Sobe Ebola virus, with very high mortality, which occurs among animals and occasionally in humans, the transmission between them is difficult because those who are infected die quickly and there is no time of infection among the species.
"The dengue virus can jump from animals to humans, we may have infection between humans and the virus will eventually die because it is not as efficient transmission between us. And finally, the HIV / AIDS, which is transmitted from primates to humans and now the contagion is purely between our species, which has become a global epidemic that we know. "
The specialist said that in reviewing from a biological virus, influenza, "the first thing that strikes one is that we are contending with a biological entity that is a chimera, that is, has different origins, not only have a virus with components of pig, poultry and humans that may affect them, but we also know that there are cases of humans infected pigs. "
In turn, Susana Magall?n, Institute of Biology, UNAM, said that the deaths were in the country due to the influenza epidemic was probably due to the culture of self that occurs in the majority of citizens, is the result of poverty, lack of time to assist the public health system, "which sometimes is more sick of what is entered."
Both researchers are part of the Group of Evolutionary Analysis of Influenza Virus, involving specialists from various academic institutions and health facilities, who voluntarily have analyzed the new pathogen from each of their areas without institutional support.
