Abstract

The complete genome sequence of an avian paramyxovirus serotype 1 (APMV-1) isolated from a black-headed gull (Larus ridibundus) in Sweden was determined and compared with other APMV-1 sequences. Sequence analyses showed that this isolate consists of six genes in the order 3'-NP-P-M-F-HN-L-5', is 15,186 nucleotides long, and contains a typical, avirulent fusion protein cleavage site. It was also shown to have a hemagglutinin-neuraminidase protein with a length of 585 amino acids (aa) instead of the expected 616 aa. Phylogenetic analyses showed that the isolate belongs to genotype I, and the relationship with some other, known APMV-1 virus sequences was revealed. Waterfowl have been considered to act as a reservoir for APMV-1 and, therefore, it is important to broaden the knowledge of viruses circulating within this population.

摘要

测定了从瑞典一只黑头鸥（红嘴鸥）分离出的禽副粘病毒1型（APMV-1）的全基因组序列，并与其他APMV-1序列进行了比较。序列分析表明，该分离株由六个基因组成，顺序为3'-NP-P-M-F-HN-L-5'，长度为15186个核苷酸，含有典型的无毒融合蛋白切割位点。还显示其血凝素神经氨酸酶蛋白长度为585个氨基酸，而非预期的616个氨基酸。系统发育分析表明，该分离株属于基因型I，并揭示了其与其他一些已知APMV-1病毒序列的关系。水禽被认为是APMV-1的储存宿主，因此，拓宽对该种群中传播的病毒的认识很重要。
