| nucleotide and predicted amino acid sequence-based analysis of the avian metapneumovirus type c cell attachment glycoprotein gene: phylogenetic analysis and molecular epidemiology of u.s. pneumoviruses. | a serologically distinct avian metapneumovirus (ampv) was isolated in the united states after an outbreak of turkey rhinotracheitis (trt) in february 1997. the newly recognized u.s. virus was subsequently demonstrated to be genetically distinct from european subtypes and was designated ampv serotype c (ampv/c). we have determined the nucleotide sequence of the gene encoding the cell attachment glycoprotein (g) of ampv/c (colorado strain and three minnesota isolates) and predicted amino acid sequ ... | 2003 | 12682171 |
| 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 |
| seroprevalence of avian pneumovirus in minnesota turkeys. | avian pneumovirus (apv) causes respiratory tract infection in turkeys and was first seen in the united states in colorado in late 1996. in early 1997, the disease was recognized in minnesota and caused estimated losses of up to 15 million dollars per year. this virus has not been reported in the other turkey producing states. we here report the seroprevalence of apv in minnesota from august 1998 to july 2002. the average rate of seroprevalence has been 36.3% (range = 14.2%-64.8%). a seasonal bia ... | 2003 | 14562899 |
