Position-specific entropy profiles created from scanning 306 human and 95 avian influenza A viral genomes showed that 228 of 4591 amino acid residues yielded significant differences between these 2 viruses. We subsequently used 15,785 protein sequences from the National Center for Biotechnology Information (NCBI) to assess the robustness of these signatures(More)
Enterovirus 71 (EV71) infection may be asymptomatic or may cause diarrhea, rashes, and hand, foot, and mouth disease (HFMD). However, EV71 also has the potential to cause severe neurological disease. To date, little is known about the molecular mechanisms of host response to EV71 infection. In this report, we utilized cDNA microarray to profile the kinetics(More)
Mechanisms related to the neuropathogenesis of enterovirus 71 infection remain unclear. This investigation conducts a comprehensive study of the apoptotic pathways in neural and non-neural cells following enterovirus 71 infection. Infections with enterovirus 71 not only induce classical cytopathic effects in SF268 (human glioblastoma), SK-N-MC (human(More)
Picornaviruses cause several diseases, not only in humans but also in various animal hosts. For instance, human enteroviruses can cause hand-foot-and-mouth disease, herpangina, myocarditis, acute flaccid paralysis, acute hemorrhagic conjunctivitis, severe neurological complications, including brainstem encephalitis, meningitis and poliomyelitis, and even(More)
BACKGROUND Studies regarding coxsackievirus A6 (CVA6) infection were limited. In Taiwan, outbreaks of CVA6 occurred in 2009 and 2010, respectively, but the clinical manifestations were markedly different. We conducted a study to compare the clinical features and genomic sequence between the two years. METHODOLOGY/PRINCIPAL FINDINGS In 2009 and 2010, 205(More)
BACKGROUND This study is to determine the seroprevalence of the pandemic influenza A H1N1 virus (pH1N1) in Taiwan before and after the 2009 pandemic, and to estimate the relative severity of pH1N1 infections among different age groups. METHODOLOGY/PRINCIPAL FINDINGS A total of 1544 and 1558 random serum samples were collected from the general population(More)
A swine-origin influenza A was detected in April 2009 and soon became the 2009 H1N1 pandemic strain (H1N1pdm). The current study revealed the genetic diversity of H1N1pdm, based on 77 and 70 isolates which we collected, respectively, during the 2009/2010 and 2010/2011 influenza seasons in Taiwan. We focused on tracking the amino acid transitioning of(More)
