Abstract:
:The gene encoding the attachment glycoprotein (G) was sequenced in three French isolates of-subgroup C avian metapneumovirus (APV-C) from ducks. With 1771 nt, this gene proved as long as recently published for North-American APV-C isolates from turkeys. The nt sequences of the duck viruses shared 99% identity but proved only 75-83% identical with their North-American counterparts, viruses of both origins encoding 585 amino acid (aa)-long G proteins. Alignments revealed more homogeneity within the European and North-American groups (at least 98 and 79% aa identity, respectively) than between European and North-American viruses (at best 70% a identity), and confirmed the presence of an extracellular divergent domain (positions 302-484) in APV-C G. A phylogenetic analysis demonstrated that North-American and French isolates of APV-C belonged to significantly different genetic lineages, in agreement with the different geographical origin and host species of these viruses.
