| 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 |
