| experimental and serologic observations on avian pneumovirus (apv/turkey/colorado/97) infection in turkeys. | an avian pneumovirus (apv) was isolated from commercial turkeys in colorado (apv/colorado) showing clinical signs of a respiratory disease. the results of virus neutralization and indirect fluorescent antibody tests showed that the apv/colorado was partially related to apv subgroup a but was unrelated to apv subgroup b. turkeys experimentally inoculated with the apv/colorado were observed for signs, lesions, seroconversion, and virus shedding. thirty-six 7-wk-old turkeys were distributed into th ... | 2000 | 10737640 |
| molecular epidemiology of subgroup c avian pneumoviruses isolated in the united states and comparison with subgroup a and b viruses. | the avian pneumovirus (apv) outbreak in the united states is concentrated in the north-central region, particularly in minnesota, where more outbreaks in commercial turkeys occur in the spring (april to may) and autumn (october to december). comparison of the nucleotide and amino acid sequences of nucleoprotein (n), phosphoprotein (p), matrix (m), fusion (f), and second matrix (m2) genes of 15 u.s. apv strains isolated between 1996 and 1999 revealed between 89 and 94% nucleotide sequence identit ... | 2002 | 11980943 |
| deduced amino acid sequence of the small hydrophobic protein of us avian pneumovirus has greater identity with that of human metapneumovirus than those of non-us avian pneumoviruses. | we report here the nucleotide and deduced amino acid (aa) sequences of the small hydrophobic (sh) gene of the avian pneumovirus strain colorado (apv/co). the sh gene of apv/co is 628 nucleotides in length from gene-start to gene-end. the longest orf of the sh gene encoded a protein of 177 aas in length. comparison of the deduced aa sequence of the sh protein of apv/co with the corresponding published sequences of other members of genera metapneumovirus showed 28% identity with the newly discover ... | 2003 | 12727346 |
