Efficient Influenza A Virus Origin Detection
نویسندگان
چکیده
This research describes a novel, alignment-free method of genomic sequence comparisons based on absent nucleotide words and expression levels. Testing this method on Influenza A virus isolates, three classifications are presented which successfully identify; 1) the geographic origins of domestic bird H5N1 isolates through China and Southeast Asia during 2006, 2) the country of human H5N1 isolates crossing over from domestic bird hosts and, 3) the historical flu season from which human H3N2 isolates originated. Because comparison methods used do not rely on alignment, they are computationally efficient and well suited for large numbers of sequences in compehensive flu transmission network delineation.

Abstract Background and Objective: The emergence of a novel H1N1influenza A virus of animal origin with transmissibility from human to human poses pandemic concern. Current subtypes of Seasonal influenza A viruses spread in human are influenza A H1N1 influenza A H3N2 and influenza type B viruses. The aim of this study was to determine current strains of the H3N2 and new H1N1 subtypes of influe...

Abstract : Avian influenza virus (AIV) infection is a major cause of influenza mortality in birds and can cause human mortality and morbidity. Although the risk of infection with avian influenza virus (AIV) is generally low for most people, the pathogenic virus can cross the species barrier and acquires the ability to infect and be transmitted among the human population; therefore the ra...

The direct F.A. Method has been used for differentiation of virulent and avirulent lines of influenza viruses. A positive fluorescence was obtained indicating the level of virus in the tissues, sorbing with dried mouse powder helped to reduce non-specific staining. The virulent line showed the greatest number of fluorescent cells with the peak at 10 hours. the non-virulent lines showed a gra...

Avian Influenza (AI) is a viral respiratory disease of domestic and wild birds. In the diagnostic laboratory, it is essential to have methods for rapid detection of avian respiratory viruses. Cloacal swabs collected from chickens experimentally infected with H9 subtype AI virus, used in a reverse transcription-polymerase chain reaction (RT-PCR) assay for detection of AI. In infected animals, ...

Background and Aims: Influenza virus is a major pathogen involved in respiratory illnesses during winter seasons. A variety of diagnostic methods have been developed to identify influenza viruses in clinical specimen. Methods: Nasal and pharyngeal samples taken from patients were inoculated into Madin-Darby canine kidney (MOCK) cells and embryonated chicken eggs (ECEs). The culture media was a...
