Neuraminidase (NA) inhibitors are among the first line of defense against influenza virus infection. With the increased worldwide use of the drugs, antiviral susceptibility surveillance is increasingly important for effective clinical management and for public health epidemiology. Effective monitoring requires effective resistance detection methods. We have developed and validated a novel genot...
During recent canine influenza surveillance in South Korea, a novel H3N1 canine influenza virus (CIV) that is a putative reassortant between pandemic H1N1 2009 and H3N2 CIVs was isolated. Genetic analysis of eight genes of the influenza virus revealed that the novel H3N1 isolate presented high similarities (99.1-99.9 %) to pandemic influenza H1N1, except for in the haemagglutinin (HA) gene. The...
Background and purpose: H1N1 influenza circulate worldwide and affects the world population in case of pandemic. The aim of this study was to evaluate the awareness of urban family physicians in Mazandaran province, Iran about H1N1 influenza. Materials and methods: In a descriptive study, 373 urban family physicians were questioned. A standard questionnaire including different items were compl...
Influenza A pandemic (H1N1) 2009 virus continues to rapidly spread worldwide. In 2009, pandemic (H1N1) 2009 infection in a domestic cat from Iowa was diagnosed by a novel PCR assay that distinguishes between Eurasian and North American pandemic (H1N1) 2009 virus matrix genes. Human-to-cat transmission is presumed.
BACKGROUND Influenza viruses can generate novel reassortants in coinfected cells. The global circulation and occasional introductions of pandemic H1N1/2009 virus in humans and in pigs, respectively, may allow this virus to reassort with other influenza viruses. These possible reassortment events might alter virulence and/or transmissibility of the new reassortants. Investigations to detect such...
The unexpected emergence of pandemic H1N1 influenza has generated significant interest in understanding immunological memory to influenza and how previous encounters with seasonal strains influence our ability to respond to novel strains. In this study, we evaluate the memory T cell repertoire in healthy adults to determine the abundance and protein specificity of influenza-reactive CD4 T cells...
BACKGROUND The population-based impact of infection with swine origin influenza A (H1N1) virus infection was not clear in the early days of the epidemic towards the end of May 2009. Australia had seven confirmed cases by 22 May 2009. We aimed to compare available data on swine origin influenza A (H1N1) virus infection overseas with seasonal influenza A (H1N1) virus infection in Australia to ass...
UNLABELLED We have previously shown that 11 patients became naturally coinfected with seasonal H1N1 (A/H1N1) and pandemic H1N1 (pdm/H1N1) during the Southern hemisphere winter of 2009 in New Zealand. Reassortment of influenza A viruses is readily observed during coinfection of host animals and in vitro; however, reports of reassortment occurring naturally in humans are rare. Using clinical spec...
Highly pathogenic influenza H5N1 virus continues to pose a threat to public health. Although the mechanisms underlying the pathogenesis of the H5N1 virus have not been fully defined, it has been suggested that cytokine dysregulation plays an important role. As the human respiratory epithelium is the primary target cell for influenza viruses, elucidating the viral tropism and innate immune respo...
