Title of thesis: PHYLOGENETIC ANALYSIS OF SWINE INFLUENZA VIRUSES ISOLATED FROM HUMANS IN ALMA-ATA, KAZAKHSTAN. Rangarajan Padmanabhan, Master of Science, 2009. Thesis directed by: Associate Professor Dr.Daniel Perez, Department of Veterinary Medicine, VA-MD Regional College of Veterinary Medicine, The University of Maryland, College Park. Continuous surveillance of influenza becomes important ...
Prior to the introduction of the 2009 pandemic H1N1 virus from humans into pigs, four phylogenetic clusters (α-, β-, γ- and δ) of the haemagglutinin (HA) gene from H1 influenza viruses could be found in US swine. Information regarding the antigenic relatedness of the H1 viruses was lacking due to the dynamic and variable nature of swine lineage H1. We characterized 12 H1 isolates from 2008 by u...
Interferons (IFNs) have been shown to inhibit influenza A virus (IAV) replication and play an essential role in controlling viral infection. Here we studied the kinetics and magnitude of induction of type I and type III IFN transcripts by primary porcine airway epithelial cells (pAECs) in response to swine and human origin IAV. We observed that swine influenza viruses (SIV) replicate more effic...
The pandemic caused by the new H1N1 swine-origin influenza virus (S-OIV) strain is a worldwide health emergency and alternative therapeutic and prophylactic options are greatly needed. Two human monoclonal antibody Fab fragments (HMab) neutralizing the novel H1N1 influenza strain at very low concentrations were cloned from a patient who had a broad-range anti-H1N1 serum neutralizing activity. T...
Swine play an important role in the disease ecology of influenza. Having cellular receptors in common with birds and humans, swine provide opportunities for mixed infections and potential for genetic reassortment between avian, human, and porcine influenza. Feral swine populations are rapidly expanding in both numbers and range and are increasingly coming into contact with waterfowl, humans, an...
During 2009, pandemic influenza A(H1N1)pdm09 virus affected humans on Réunion Island. Since then, the virus has sustained circulation among local swine herds, raising concerns about the potential for genetic evolution of the virus and possible retransmission back to humans of variants with increased virulence. Continuous surveillance of A(H1N1)pdm09 infection in pigs is recommended.
Early recognition of distinguishing patterns of a novel pandemic disease is important. We introduce a methodological approach based on popular data mining techniques to extract key features and temporal patterns of swine (h1n1) flu that is discriminated from swine flu like symptoms.
A swine-origin influenza A(H1N1) virus is currently responsible for an outbreak of infections in the human population, with laboratory-confirmed cases reported in several countries and clear evidence for human-to-human transmission. We provide a description of the outbreak at the end of April 2009, and a brief review of the zoonotic potential of swine influenza viruses.
Understanding the origin of infectious diseases provides scientifically based rationales for implementing public health measures that may help to avoid or mitigate future epidemics. The recent ancestors of a pandemic virus provide invaluable information about the set of minimal genomic alterations that transformed a zoonotic agent into a full human pandemic. Since the first confirmed cases of t...
