Worldwide spreading of H5 and H7 highly pathogenic influenza viruses of the avian origin, which periodically infect and kill humans without prior adaptation, poses a constant threat of the new pandemic. The effectiveness of the pandemic prevention completely depends on the quality of the existing influenza vaccines. Typical methods of the vaccine production from the antigenically relevant strai...

We report resonance-enhanced multiphoton ionization spectra of the isotopologues fluorobenzene-h5 and fluorobenzene-d5. By making use of quantum chemical calculations, the changes in the wavenumber of the vibrational modes upon deuteration are examined. Additionally, the mixing of vibrational modes both between isotopologues and also between the two electronic states is discussed. The isotopic ...

During a 3-year surveillance study for avian influenza virus (AIV) infections at the Jeziorsko reservoir in central Poland, 549 oropharyngeal or cloacal swabs from 366 birds of 14 species belonging to 3 orders (Anseriformes, Charadriiformes and Gruiformes) were tested. AIV was detected in 14 birds (3.8%): Common Teals (12x), Mallard (1x) and Garganey (1x). Three potentially dangerous H5 AIV wer...

We studied the prevalence of influenza A virus in wintering waterfowl from the Central Flyway on the Gulf Coast of Texas. Of 5,363 hunter-harvested migratory and resident waterfowl and wetland-associated game birds sampled during 3 consecutive hunting seasons (September-January 2006-07, 2007-08, and 2008-09), real-time reverse transcription-PCR detected influenza A matrix sequences in 8.5% of s...

A monoclonal antibody (MoAb) H5 (IgG2b) was obtained by fusion between SP2/0, mouse myeloma cell line and spleen cells from BC3Fl mice immunized with HEL, a erythroleukemia cell line. MoAb H5 precipitated a 26 kilodalton (KD) polypeptide in reduced condition. It reacted with platelets, monocytes, eosinophiles, 13% of lymphocytes, thymocytes and colony-forming unitsgranulocyte/monocyte (CFU-GM),...

Among the erythrocytes of chicken, trout, carp, and sucker, the relative proportion of the lysine-rich histone H5 varied from 20 to 0% of the total histones. Following digestion of nuclear chromatin with micrococcal nuclease, each of them displayed a longer DNA repeat length and greater repeat length heterogeneity than found in liver chromatin. Fish erythrocytes possessed similar repeat lengths...

The binding curves of histones H1 and H5 to chromatin in nuclei have been determined by a novel method which utilises the differential properties of free and bound histones on cross-linking with formaldehyde. The dissociation is thermodynamically reversible as a function of [NaCl]. The binding curves are independent of temperature over the range 4 degrees - 37 degrees C and independent of pH ov...
