| using nested rt-pcr analyses to determine the prevalence of avian influenza viruses in passerines in western slovakia, during summer 2007. | the prevalence of avian influenza virus (aiv), together with the distribution of different aiv subtypes, was studied in migratory waterfowl and terrestrial birds caught in western slovakia during summer 2007. both oropharyngeal and cloacal swabs were collected. screening of samples revealed that 18% of oropharyngeal and 18% of cloacal samples were positive for aiv. samples from both the oropharynx and cloaca were positive in only 6.6% of cases. a total of 10 different subtypes of haemagglutinin ... | 2008 | 18777249 |
| prevalence of avian influenza viruses, borrelia garinii, mycobacterium avium, and mycobacterium avium subsp. paratuberculosis in waterfowl and terrestrial birds in slovakia, 2006. | the prevalence of borrelia, mycobacteria and avian influenza virus (aiv) infections, together with the distribution of different aiv subtypes, was studied in migratory waterfowl and terrestrial birds trapped in three localities in slovakia during 2006. samples obtained from waterfowl captured in the senianske ponds area of eastern slovakia showed the highest diversity of aiv isolates. a total of 13 different subtypes were detected in 19 samples from this location (h1n2, h2n2, h3n2, h6n6, h7n6, h ... | 2008 | 18798030 |
| isolation and characterization of chicken lung mesenchymal stromal cells and their susceptibility to avian influenza virus. | in this study, we isolated and characterized mesenchymal stromal cells (mscs) from the lungs of 1- to 2-week-old chickens. microscopically, the cultured cells showed fibroblast-like morphology. phenotypically these cells expressed cd44, cd90, cd105 and the transcription factor pouv, which has been shown to be critical for stem cell self-renewal and pluripotency. the multipotency of chicken mscs was demonstrated by their ability to undergo adipogenic and osteogenic differentiation. like chicken b ... | 2010 | 20026347 |
