The fast diagnosis by different methodologies of the influenza virus

This paper presents the causative agent of the epidemic of the influenza in our country during the season 2009-2010. It also shows the effectiveness of the molecular diagnosis for Influenza virus by the means of the real-time PCR method in comparative of classical virological ones. Also in this paper we have presented the antigenic characterization of this virus which caused the pandemic during 2009-2010 years. We have collected and processed with several diagnostic methods like imunoflorescent assay, rapid tests, isolation and molecular method 409 samples. These were collected by the means of a Sentinel Surveillance throughout Albania, (tampon nasal- pharyngeal) from people suspected of influenza in different ages. To isolate the virus of influenza we have used two methods: the method of isolation of influenza in the cell line of MDCK and also the isolation of the viral RNA by the means of the molecular method. The identifications of the isolates were carried out through the reactions of the hem agglutination inhibition and we have used also the method of Immunofluorescence and rapid test for the antigen detection of influenza virus. The results of the virus analyses are given in the relevant figures. The positive isolates were sent to the International Center of Influenza in London to be confirmed and also to have a further genetic analysis through molecular methods. From these tests performed during the season 2009-2010, it came out that our country was affected by one strain of influenza type A, AH1N1 variant A/California/2009/11. This strain circulated in the whole world causing the pandemic of 2009 and was a new variant deriving from the fusion of 4 strains of Influenza a process which occurred in pigs. These variants have affected the majority of the countries in Europe and in the world.
