Related Articles Differential host gene expression in cells infected with highly pathogenic H5N1 avian influenza Viruses. Vet Immunol Immunopathol. 2008 Jun 3; Authors: Sarmento L, Afonso CL, Estevez C, Wasilenko J, Pantin-Jackwood M In order to understand the molecular mechanisms by which different strains of avian influenza Viruses overcome host response in birds, we used a complete chicken genome microarray to compare early gene expression levels in chicken embryo fibroblasts (CEF) infected with two avian influenza Viruses (AIV), A/CK/Hong Kong/220/97 and A/Egret/Hong Kong/757.2/02, with different replication characteristics. Gene ontology revealed that the genes with altered expression are involved in many vital functional classes including protein metabolism, translation, transcription, host defense/immune response, ubiquitination and the cell cycle. Among the immune-related genes, MEK2, MHC class I, PDCD10 and Bcl-3 were selected for further expression analysis at 24hpi using semi-quantitive RT-PCR. Infection of CEF with A/Egret/Hong Kong/757.2/02 resulted in a marked repression of MEK2 and MHC class I gene expression levels. Infection of CEF with A/CK/Hong Kong/220/97 induced an increase of MEK2 and a decrease in PDCD10 and Bcl-3 expression levels. The expression levels of alpha interferon (IFN-alpha), myxovirus resistance 1 (Mx1) and interleukin-8 (IL-8) were also analyzed at 24hpi, showing higher expression levels of all of th ...

Related Articles Influenza Viruses and the evolution of avian influenza virus H5N1. Int J Infect Dis. 2008 May;12(3):233-8 Authors: Skeik N, Jabr FI Although small in size and simple in structure, influenza Viruses are sophisticated organisms with highly mutagenic genomes and wide antigenic diversity. They are species-specific organisms. Mutation and reassortment have resulted in newer Viruses such as H5N1, with new resistance against anti-viral medications, and this might lead to the emergence of a fully transmissible strain, as occurred in the 1957 and 1968 pandemics. Influenza Viruses are no longer just a cause of self-limited upper respiratory tract infections; the H5N1 avian influenza virus can cause severe human infection with a mortality rate exceeding 50%. The case death rate of H5N1 avian influenza infection is 20 times higher than that of the 1918 infection (50% versus 2.5%), which killed 675000 people in the USA and almost 40 million people worldwide. While the clock is still ticking towards what seems to be inevitable pandemic influenza, on April 17, 2007 the U.S. Food and Drug Administration (FDA) approved the first vaccine against the avian influenza virus H5N1 for humans at high risk. However, more research is needed to develop a more effective and affordable vaccine that can be given at lower doses. PMID: 17913533 [PubMed - indexed for MEDLINE] ...

Related Articles Efficacy of disinfectants and hand sanitizers against avian respiratory Viruses. Avian Dis. 2008 Jun;52(2):199-202 Authors: Patnayak DP, Prasad AM, Malik YS, Ramakrishnan MA, Goyal SM Disinfectants play a major role in the control of animal diseases by decontaminating the farm environment. We evaluated the virucidal efficacy of nine commonly used disinfectants on a nonporous surface contaminated experimentally with avian metapneumovirus (aMPV), avian influenza virus, or Newcastle disease virus (NDV). Phenolic compounds and glutaraldehyde were found to be the most effective against all three Viruses. Quaternary ammonium compounds were effective against aMPV but not against the other two Viruses. In addition, efficacy of commercially available hand sanitizers was evaluated on human fingers contaminated with aMPV and NDV. All three hand sanitizers tested were found to be effective against both Viruses within 1 min of application on fingers. PMID: 18646446 [PubMed - in process] ...

Persons infected with schistosomes, and possibly other parasitic worm infections, may be more likely to become infected with HIV than persons without worm infections, according to a new study. Researchers found that the infectious dose of an HIV-like virus necessary to infect rhesus macaques was 17-fold lower in animals with acute schistosomiasis than in controls. ...
