cord-271897-9oqzsd70	Domanska-Blicharz, Katarzyna	Molecular epidemiology of infectious bronchitis virus in Poland from 1980 to 2017	2020-01-07		.txt	text/plain	6549	299	54	Additionally, two strains from 1989 and 1997 formed a separate branch of the phylogenetic tree categorized as unique early Polish variants, and one strain was revealed to be the recombinant of these and GI-1 lineage viruses. Irrespective of year of isolation and S1-dependent genotype, the genome sequences of Polish IBV strains showed the presence of six genes and 13 ORFs: 5′UTR-1a-1b-S-3a-3b-E-M-4b-4c-5a-5b-N-6b-3′UTR, however their individual genes and putative proteins had different lengths. Genotyping based on phylogenetic analysis of full S1 coding region sequences of 34 Polish IBV strains from the years 1980-2017 grouped (caption on next page) K. Phylogenetic analysis of the full S1 coding region showed that strain 80/ 1989 forms a separate branch on the tree designated as early Polish and was classified as a unique variant of IBV within the GI genotype.	./cache/cord-271897-9oqzsd70.txt	./txt/cord-271897-9oqzsd70.txt
