In a previous report [T. J. Kleine, A. Gladfelter, P. N. Lewis, and S. A. Lewis. Am. J. Physiol. 268 ( Cell Physiol. 37): C1114-C1125, 1995], we found that the cationic DNA-binding proteins histones H4, H1, and H5 caused a voltage-dependent increase in the transepithelial conductance in rabbit urinary bladder epithelium. In this study, results from lipid bilayer experiments suggest that histone...
BACKGROUND H5 DNA priming was previously shown to improve the antibody response to influenza A(H5N1) monovalent inactivated vaccine (MIV) among individuals for whom there was a 24-week interval between prime and boost receipt. This study defines the shortest prime-boost interval associated with an improved response to MIV. METHODS We administered H5 DNA followed by MIV at intervals of 4, 8, 1...
The emergence of highly pathogenic avian influenza A virus (HPAIV) subtype H5N1 in 1997 has since resulted in large outbreaks in poultry and in transmission from poultry to humans, mostly in southeast Asia, but also in several European countries. Effective diagnosis and control measures are essential for the management of HPAIV infections. To develop a rapid diagnostic test, a panel of murine m...
Maximin H5 is an anionic antimicrobial peptide from amphibians, which carries a C-terminal amide moiety, and was found to be moderately haemolytic (20%). The α-helicity of the peptide was 42% in the presence of lipid mimics of erythrocyte membranes and was found able to penetrate (10.8 mN m(-1)) and lyse these model membranes (64 %). In contrast, the deaminated peptide exhibited lower levels of...
H9N2 avian influenza virus (AIV) of genotype S frequently donate internal genes to facilitate the generation of novel reassortants such as H7N9, H10N8, H5N2 and H5N6 AIVs, posing an enormous threat to both human health and poultry industry. However, the pathogenicity and transmission of reassortant H5 viruses with internal gene cassette of genotype S H9N2-origin in chickens and mice remain unkn...
Potassium (K+) channels are highly selective for K+ ions but their unitary conductances are quite divergent. Although Kir6.1 and Kir6.2 are highly homologous and both form functional K+ channels with sulfonylurea receptors, their unitary conductances measured with 150 mM extracellular K+ are approximately 35 and 80 pS, respectively. We found that a chain of three amino acid residues N123-V124-R...
Sequence analysis of the endoproteolytic cleavage site within the hemagglutinin (HA) precursor protein HA(0) is fundamental for studies of the molecular biology of influenza A viruses, in particular, for molecular pathotyping of subtype H5 and H7 isolates. A current problem for routine diagnostics is the emergence of new strains of the H5 or H7 subtype or even other subtypes which escape detect...
Of 4,268 wild ducks sampled in Canada in 2005, real-time reverse transcriptase-PCR detected influenza A matrix protein (M1) gene sequence in 37% and H5 gene sequence in 5%. Mallards accounted for 61% of samples, 73% of M1-positive ducks, and 90% of H5-positive ducks. Ducks hatched in 2005 accounted for 80% of the sample.
Two murine monoclonal antibodies (MAb), 2C5-F10 and 8D1-H10, reactive with Escherichia coli O4 and H5 antigens, respectively, were generated and characterized. Enzyme immunoassays and immunoblots demonstrated that MAb 2C5-F10 reacted specifically with lipopolysaccharide O antigen of E. coli O4 isolates, while MAb 8D1-H10 reacted with E. coli strains expressing H5 flagella.
Longitudinal surveillance of 2 live bird markets in Cambodia revealed year-round, high co-circulation of H5, H7, and H9 influenza viruses. We detected influenza A viruses in 51.3% of ducks and 39.6% of chickens, and co-infections, mainly by H5 and H9 viruses, in 0.8% of ducks and 4.5% of chickens.
