analytical and clinical validation of novel real-time reverse transcriptase-polymerase chain reaction assays for the clinical detection of swine-origin h1n1 influenza viruses.during the early stages of the 2009/2010 swine-origin h1n1 influenza a (s-oiv h1n1 flua) outbreak, the development and validation of sensitive and specific detection methods were a priority for rapid and accurate diagnosis. between may and june 2009, 2 real-time reverse transcriptase-polymerase chain reaction (rrt-pcr) assays targeting the hemagglutinin and neuraminidase genes of the s-oiv h1n1 flua virus were developed. these assays are highly specific, showing no cross-reactivity against a pan ...201121251560
detection of resistance mutations to antivirals oseltamivir and zanamivir in avian influenza a viruses isolated from wild birds.the neuraminidase (na) inhibitors oseltamivir and zanamivir are the first-line of defense against potentially fatal variants of influenza a pandemic strains. however, if resistant virus strains start to arise easily or at a high frequency, a new anti-influenza strategy will be necessary. this study aimed to investigate if and to what extent na inhibitor-resistant mutants exist in the wild population of influenza a viruses that inhabit wild birds. na sequences of all na subtypes available from 54 ...201121253602
plant-based rapid production of recombinant subunit hemagglutinin vaccines targeting h1n1 and h5n1 influenza.in 2009, a novel h1n1 swine influenza virus was isolated from infected humans in mexico and the united states, and rapidly spread around the world. another virus, a highly pathogenic avian influenza virus of the h5n1 subtype, identified by the world health organization as a potential pandemic threat in 1997, continues to be a significant risk. while vaccination is the preferred strategy for the prevention and control of influenza infections, the traditional egg-based approach to producing influe ...201121266846
acute necrotizing encephalopathy of childhood: a fatal complication of swine flu.acute necrotizing encephalopathy of childhood (anec) is a rare condition characterized by the presence of multifocal symmetrical brain lesions involving mainly thalami, brainstem, cerebellum and white matter. anec is a serious and life threatening complication of simple viral infections. we present a case of a young child who developed this condition with classical clinical and radiological findings consistent with anec, secondary to swine flu (h1n1). he needed ventilatory support and had profou ...201121333249
using electronic patient records to assess the impact of swine flu (influenza h1n1) on mental health patients.electronic patient records are increasingly used in primary care research, but rarely in psychiatric research. little is known about how people with pre-existing mental illness respond to public health threats.201121271827
determinants of adults' intention to vaccinate against pandemic swine flu.vaccination is one of the cornerstones of controlling an influenza pandemic. to optimise vaccination rates in the general population, ways of identifying determinants that influence decisions to have or not to have a vaccination need to be understood. therefore, this study aimed to predict intention to have a swine influenza vaccination in an adult population in the uk. an extension of the theory of planned behaviour provided the theoretical framework for the study.201121211000
swine outbreak of pandemic influenza a virus on a canadian research farm supports human-to-swine transmission.swine outbreaks of pandemic influenza a (ph1n1) suggest human introduction of the virus into herds. this study investigates a ph1n1 outbreak occurring on a swine research farm with 37 humans and 1300 swine in alberta, canada, from 12 june through 4 july 2009.201121148514

potent inhibitor design against h1n1 swine influenza: structure-based and molecular dynamics analysis for m2 inhibitors from traditional chinese medicine database.the rapid spread of influenza virus subtype h1n1 poses a great threat to million lives worldwide. to search for new anti-influenza compounds, we performed molecular docking and molecular dynamics simulation to identify potential traditional chinese medicine (tcm) constituents that could block influenza m2 channel activity. quinic acid, genipin, syringic acid, cucurbitine, fagarine, and methyl isoferulate all have extremely well docking results as compared to control amantadine. further de novo d ...201121142218
development of two types of rapid diagnostic test kits to detect the hemagglutinin or nucleoprotein of the swine-origin pandemic influenza a virus h1n1.since its emergence in april 2009, pandemic influenza a virus h1n1 (h1n1 pdm), a new type of influenza a virus with a triple-reassortant genome, has spread throughout the world. initial attempts to diagnose the infection in patients using immunochromatography (ic) relied on test kits developed for seasonal influenza a and b viruses, many of which proved significantly less sensitive to h1n1 pdm. here, we prepared monoclonal antibodies that react with h1n1 pdm but not seasonal influenza a (h1n1 an ...201121228147
the nonadaptive nature of the h1n1 2009 swine flu pandemic contrasts with the adaptive facilitation of transmission to a new host.the emergence of the 2009 h1n1 influenza pandemic followed a multiple reassortment event from viruses originally circulating in swines and humans, but the adaptive nature of this emergence is poorly understood.201121211019
pandemic h1n1 influenza virus causes a stronger inflammatory response than seasonal h1n1 influenza virus in ferrets.a 2009 h1n1 influenza virus pandemic, which had its origin in swine, caused severe illness and mortality in humans. inflammatory responses may be responsible for pathogenesis caused by infection with influenza viruses. to better understand the pathogenic mechanism, clinical signs and inflammatory responses in ferrets infected with the pandemic h1n1 were compared with those caused by seasonal h1n1 influenza virus. ferrets infected with the 2009 pandemic h1n1 virus displayed higher body temperatur ...201121234768
possible reason for cross-species and cross-subtype reassortment in polymerase basic protein 2 from influenza a virus.the reassortment in proteins from influenza a viruses among human, swine, and eurasian avian strains formed a new influenza a virus leading to the first pandemic in this century, which suggests that the barrier between species and between subtypes would not be strong enough to prevent the cross-species infection and cross-subtype reassortment from occurring. in this study, we intensively used the anova including its model i and model ii to analyze 2430 polymerase basic proteins 2 (pb2) of influe ...201121171947
comparison of two h1n2 swine influenza a viruses from disease outbreaks in pigs in sweden during 2009 and 2010.the influenza a virus subtypes h1n1, h1n2 and h3n2 are prevalent in pig populations worldwide. in the present study, two relatively uncommon swine influenza virus (siv) h1n2 subtypes, isolated in sweden in 2009 and 2010, were compared regarding their molecular composition and biological characteristics. the differences regarding markers purportedly related to pathogenicity, host adaptation or replication efficiency. they included a truncated pb1-f2 protein in the earlier isolate but a full lengt ...201121253862

human parainfluenza virus type 3 (hpiv 3) viral community-acquired pneumonia (cap) mimicking swine influenza (h1n1) during the swine flu pandemic.the swine influenza (h1n1) pandemic began in mexico in 2009 and quickly spread worldwide. during the h1n1 pandemic, many patients were admitted to the winthrop-university hospital with influenza-like illnesses (ilis). many hospitalized adults had h1n1 pneumonia diagnosed by laboratory or clinical criteria. however, the laboratory diagnosis of h1n1 was problematic. the rapid influenza (quickvue a/b [quidel, san diego, ca]) test frequently showed false-negative results. reverse transcriptase-polym ...201120888645
quantitative analysis of influenza m2 channel blockers.the influenza m2 h(+) channel enables the concomitant acidification of the viral lumen upon endosomic internalization. this process is critical to the viral infectivity cycle, demonstrated by the fact that m2 is one of only two targets for anti-flu agents. however, aminoadamantyls that block the m2 channel are of limited therapeutic use due to the emergence of resistance mutations in the protein. herein, using an assay that involves expression of the protein in escherichia coli with resultant gr ...201120831860
the new influenza a (h1n1/09): symptoms, diagnostics, and autopsy results.the first infections of the new h1n1 ("swine flu") virus were announced in april 2009. soon after, case numbers were observed to be climbing virtually worldwide. in most cases, infections appeared rather mild with typical flu symptoms. in contrast to the seasonal flu, however, cases with vomiting and diarrhea were also reported, and the affected age group seemed to be younger. sudden and fatal progression affected mostly those under 60 years of age. the autopsy reports of two fatalities with the ...201120734056
Genetic analysis and antigenic characterization of swine origin influenza viruses isolated from humans in the United States, 1990-2010.Swine influenza viruses (SIV) have been recognized as important pathogens for pigs and occasional human infections with swine origin influenza viruses (SOIV) have been reported. Between1990 and 2010, a total of twenty seven human cases of SOIV infections have been identified in the United States. Six viruses isolated from1990 to 1995 were recognized as classical SOIV (cSOIV) A(H1N1). After 1998, twenty-one SOIV recovered from human cases were characterized as triple reassortant (tr_SOIV) inherit ...201222078166
contemporary epidemiology of north american lineage triple reassortant influenza a viruses in pigs.the 2009 pandemic h1n1 infection in humans has been one of the greatest concerns for public health in recent years. however, influenza in pigs is a zoonotic viral disease well-known to virologists for almost one century with the classical h1n1 subtype the only responsible agent for swine influenza in the united states for many decades. swine influenza was first recognized clinically in pigs in the midwestern u.s. in 1918 and since that time it has remained important to the swine industry through ...201222266673
complicated secondary pneumonia after swine-origin influenza a virus infection in an immunocompetent patient.the pandemic of the swine-origin influenza a virus (s-oiv) in 2009 demonstrated severe viral pneumonia followed by acute respiratory distress syndrome (ards). although ards would be caused by the influenza virus pneumonia itself, it has remained unclear whether other respiratory viral or bacterial infections coexist with s-oiv pneumonia. we report an immunocompetent patient with methicillin-resistant staphylococcus aureus (mrsa) and herpes simplex virus (hsv) pneumonia secondary to s-oiv infec ...201222251837
[serological detection of emerging viral infections in wild boars from different hunting regions of southern germany].wild boars represent a possible virus reservoir for notifiable diseases of farm animals, including aujeszky's disease (ad) and classical swine fever (csf). monitoring of the epidemiological situation in the wild boar population is especially relevant in countries that are officially free from these diseases. apart from oie-notifiable diseases, other viral agents that are widely distributed and play a significant role in farm animals, such as the porcine reproductive and respiratory syndrome viru ...201222331288
