Researchers at the Instituto Oswaldo Cruz (IOC / Fiocruz) completed the first genetic sequences of influenza A (H1N1) mapped in Brazil. According to the Ministry of Health, the material was developed from data collected from three patients - two in Rio de Janeiro and Minas Gerais - all diagnosed in the laboratory. "A preliminary analysis showed that the virus found in Brazilian patients are kept together and compared with sequences deposited by other countries, we see that they maintain the same characteristics, ie, there is no indication of change in the virus circulating in elsewhere ", says Fernando Motta, a researcher at the Laboratory of Respiratory Viruses and Measles IOC.
According to him, the genetic sequencing is an essential tool to monitor the evolution of the virus in the country and opens the possibility for the development of diagnostic protocols. The Brazilian researchers chose to sequence the gene for matrix protein (M protein) of the virus. Because the influenza virus genome is segmented - is not formed by a unique sequence of RNA, but eight segments - was chosen as the M protein gene, one of the most important in viral structure. Researchers are awaiting the arrival of supplies to continue the sequencing of other genes of the virus. Four more genes will be sequenced: neuraminidase, hemagglutinin, NS and PB1.
According to the Ministry of Health, the survey was filed on May 15 in the genetic information from the National Center for Biotechnology Information (NCBI), based at the National Institute of Health (NIH), the United States. The database brings together genetic sequences of nearly all known organisms, including the human genome.
