Background and Aims: The novel approaches in influenza vaccination have targeted more conserved viral proteins such as nucleoprotein (NP) to provide cross protection against all serotypes of influenza A viruses. Influenza specific cytotoxic T lymphocytes (CTL) are able to lyse influenza-infected cells by recognition of NP, the major target molecule in virus for CTL responses. On the other hand,...
Introduction: influenza A (H1N1) disease is a serious viral disease which recently has been a pandemic. The purpose of this study is a determination of knowledge and attitude of students living in student accommodation and Iran University of Medical Sciences, about influenza A (H1N1) disease. Methods: This cross-sectional research study (descriptive _ analytic) that the 150 students, the clust...
background influenza type a (h1n1) causes an epidemic disease, resulting in thousands of deaths throughout the world. objectives our aim was comparing the efficacy of two different methods in isolating the influenza (h1n1) virus including cell culture and real-time pcr in tabriz and suburbs. patients and methods of throat swab samples, 220 were collected in viral transport medium (vtm) from pat...
Influenza is a contagious viral disease that is seen in avian, human and other mammals, so its control is important. Vaccination against influenza virus subtype H9N2 is one of the ways in controlling program, for this reason several vaccines has been produced. Recently, application of inactivated oil-emulsion vaccines in poultry for controlling low pathogenic avian influenza is increasing. At p...
prolonged cough occurs in a large proportion of the 2 million pilgrims who participate in the annual hajj in saudi arabia. there is no unique cause for pilgrims’ respiratory involvement, but several studies suggest a high incidence of influenza as a cause of the disease. to determine influenza vaccine efficacy against respiratory disease in pilgrims, we conducted two similar cohort studies on 5...
A swine influenza outbreak occurred on a commercial pig farm in Thailand. Outbreak investigation indicated that pigs were co-infected with pandemic (H1N1) 2009 virus and seasonal influenza (H1N1) viruses. No evidence of gene reassortment or pig-to-human transmission of pandemic (H1N1) 2009 virus was found during the outbreak.
On June 11, 2009 the World Health Organization (WHO) declared a new H1N1 influenza pandemic. This pandemic strain is as transmissible as seasonal H1N1 and H3N2 influenza A viruses. Major concerns facing this pandemic are whether the new virus will replace, co-circulate and/or reassort with seasonal H1N1 and/or H3N2 human strains. Using the ferret model, we investigated which of these three poss...
