sequence divergence of measles virus haemagglutinin during natural evolution and adaptation to cell culture.phylogenetic analysis of the sequence of the h gene of 75 measles virus (mv) strains (32 published and 43 new sequences) was carried out. the lineage groups described from comparison of the nucleotide sequences encoding the c-terminal regions of the n protein of mv were the same as those derived from the h gene sequences in almost all cases. the databases document a number of distinct genotype switches that have occurred in madrid (spain). well-documented is the complete replacement of lineage g ...19979010291
measles virus genotype circulation in spain after implementation of the national measles elimination plan 2001-2003.molecular characterization of measles virus is important for disease surveillance and for monitoring elimination of the virus throughout the world. furthermore, knowledge of genotype distribution in as many countries as possible, is useful for tracing the origin of a strain, especially in countries without endemic measles disease, where most cases are imported. data on genotypes circulating in spain from 1970 to 1997 showed the prevalence of genotypes c1, c2, and d6, with subsequent replacement ...200515543577
