Widespread recombination within human parechoviruses: analysis of temporal dynamics and constraints.
Human parechoviruses (HPeVs), members of the family Picornaviridae, are classified into six types. To investigate the dynamics and likelihood of recombination among HPeVs, we compared phylogenies of two distant regions (VP1 and 3Dpol) of 37 HPeV isolates (types 1 and 3-5) and prototype sequences (types 1-6). Evidence for frequent recombination between HPeV1, 4, 5 and 6 was found. The likelihood...
متن کاملIdentification of potential recombination breakpoints in human parechoviruses.
Based on a comparison of the phylogeny of two distant regions, evidence has been found for recombination within parechoviruses. However, recombination breakpoints could not be detected in this way. We searched for potential recombination breakpoints in parechovirus by analysis of complete parechovirus sequences, including a newly isolated strain. Bootscan analysis demonstrated that parechovirus...
متن کاملGenome analysis revealed novel genotypes and recombination of the human parechoviruses prevalent in children in Eastern China
BACKGROUND Human parechovirus (HPeV) is a genus of virus in the family Picornaviridae, having two species A and B. HPeVs are common infectious agents, usually causing mild diarrhea and respiratory disease in young children. RESULTS Here, we collected and sequenced the near complete genome sequences of 17 novel HPeVs from children with diarrhea in eastern China, which showed significant nucleo...
متن کاملFrequency and dynamics of recombination within different species of human enteroviruses.
Enteroviruses are members of the family Picornaviridae that cause widespread infections in human and other mammalian populations. Enteroviruses are genetically and antigenically highly variable, and recombination within and between serotypes contributes to their genetic diversity. To investigate the dynamics of the recombination process, sequence phylogenies between three regions of the genome ...
