Complete genome sequence of an infectious bronchitis virus chimera between cocirculating heterotypic strains.

ABSTRACT: To date, multiple serotypes and genotypes of infectious bronchitis virus (IBV) have been isolated and identified. In order to provide more information on the viral evolution of IBVs, a new virulent strain named GX-NN09032, isolated from Guangxi, China, in 2009, was sequenced, and phylogenetic and recombination analyses were conducted. Furthermore, potential recombination events associated with GX-NN09032 were found in four IBV strains, including GX-YL5, DY07, CK/CH/SD09/005, TC07-2. The present study suggested that GX-NN09032 might contribute to the emergence of modern IBV variants through recombination.

Complete genome sequence of a recombinant nephropathogenic infectious bronchitis virus strain in China.

Project description:Recently, nephropathogenic infectious bronchitis virus (IBV) outbreaks have occurred in commercial broiler flocks and have been associated with a high incidence and morbidity in China. The CK/CH/Zhejiang/06/10 strain (IBV-YX10) was isolated from a 12-day-old broiler chicken in a flock of chickens with swollen speckled kidneys and distended ureters filled with uric acid in China in 2010. Here we reported the complete genomic sequence of the IBV-YX10 which was a natural recombinant nephropathogenic infectious bronchitis virus strain. These findings will contribute additional insights into the molecular characteristics of evolving IBV genomes and the need for effective control of IBV in China.

Complete genome sequence analysis of a predominant infectious bronchitis virus (IBV) strain in China.

Project description:Infectious bronchitis (IB) is one of the major diseases in poultry flocks all over the world caused by infectious bronchitis virus (IBV). In the study, the complete genome sequence of strain A2 was sequenced and analyzed, which was a predominant IBV strain in China. The results indicated that there were mutations, insertions, and deletions distributed in the whole genome. The A2 virus had the highest identity to S14 and BJ in terms of full genome, whereas had a further distance to Massachusetts strains. Phylogenetic analysis showed that A2 isolate clustered together with most Chinese strains. The results of this study suggest that strain A2 may play an important role in IBV's evolution and A2-like IBVs are predominant strains in China.

Complete genome sequence and recombination analysis of infectious bronchitis virus attenuated vaccine strain H120.

Project description:The strain H120 of infectious bronchitis virus (IBV) is one of the earliest and representative attenuated live Infectious Bronchitis vaccine strains. To investigate the genomic feature of H120 and further understand its role in the epidemiology of IBV, complete genome of H120 was sequenced and compared with sequences of other IBV strains by phylogenetic and recombination analysis. The complete genome of H120 is 27631 nucleotides in length and has a similar structure with that of Beaudette strain. We found that strain ZJ971 is probably a virulence revertant of H120. Nine amino acids changes and a three-nucleotide deletion were identified in ZJ971. Besides, potential recombination events associated with H120 were found in five IBV strains including H52, KQ6, SAIBK, Ark DPI 11, and Ark DPI 101. This study suggested that H120 might have contributed to the emergence of new IBV variants through both virulence reversion and recombination.

Complete genome analysis of Iranian IS-1494 like avian infectious bronchitis virus.

Project description:The nephropathogenic infectious bronchitis virus (IBV) strain IS-1494 like (variant-2; GI-23) was first isolated in the Middle East (1998). Despite intensive vaccinations, IS-1494 like IBVs are still circulating in Iran (the dominant genotype) and spread to other countries. Here, the full-length genome of this Iranian IS-1494 like IBV was (Mahed) determined to understand its evolutionary relationships. The genome consists of 27,652 nucleotides, with mutations in most of the structural genes. Thirteen open reading frames (ORFs) were predicted in the Mahed isolate (5' UTR-1a-1b-S-3a-3b-E-M-4b-4c-5a-5b-N-6b-3' UTR). ORFs 4b, 4c, and 6b, which has rarely been reported, were present in the Mahed genome. According to phylogenetic analysis of the full-length genome, 1a, S2, M, E, N protein, Mahed isolate clustered with the QX type strain. Based on the partial 1b, S1, Mahed clustered with the Q1 strain. The full-length genome of Mahed isolate shared the highest sequence homology with Gray and JMK (90.06-90.07%) and was least related to the Vic-s (86.21%). These data show that evolutionary variation because of recombination in IBV plays a major role in the adaptation and origin of IBV leading to new genetic and types of the virus strain.

Complete genome sequence of a novel infectious bronchitis virus strain circulating in China with a distinct S gene.

Project description:An avian infectious bronchitis virus (IBV) was isolated and identified from a commercial layer flock vaccinated with live attenuated H120 vaccine in China, designed as ck/CH/IBTZ/2012. To determine the origination and evolution of this isolated strain, we have carried out a complete genome sequencing of this strain. The genome of the ck/CH/IBTZ/2012 strain is 27,691 nucleotides in length and includes more than 10 open reading frames. Sequence comparison and phylogenetic analysis based on the full-length genomic sequences showed that ck/CH/IBTZ/2012 is mostly related to the LX4-like strains. However, sequence analysis based on the spike protein (S) gene sequences revealed that ck/CH/IBTZ/2012 possesses a distinct S gene setting it apart from the Massachusetts-type strains and LX4-type strains. The cleavage site within the spike protein (S) of ck/CH/IBTZ/2012 is HRRKR, which is different from the majority of the IBVs in China for their cleavage sits are HRRRR. Recombination analysis showed that ck/CH/IBTZ/2012 is a chimeric virus with a LX4-like backbone except S gene which might be from an unknown strain. Based on the data presented in this paper, it can be concluded that genetic changes due to adaptive evolution and recombination both contributed to the origin of strain ck/CH/IBTZ/2012, which belongs to a new genotype.
