Abstract
Human parechovirus A (HPeV-A) is a causative agent of respiratory and gastrointestinal illnesses, acute flaccid paralysis encephalitis, meningitis, and neonatal sepsis. To clarify the characteristics of HPeV-A infection in children, 391 fecal specimens were collected from January 2014 to October 2015 from patients with acute gastroenteritis in Seoul, South Korea. Of these, 221/391 (56.5%) HPeV-A positive samples were found in children less than 2 years old. Three HPeV-A genotypes HPeV-A1 (117/221; 52.94%), HPeV-A3 (100/221; 45.25%), and HPeV-A6 (4/221; 1.81%) were detected, among which HPeV-A3 was predominant with the highest recorded value of 58.6% in 2015. Moreover, recombination events in the Korean HPeV-A3 strains were detected. Phylogenetic analysis revealed that the capsid-encoding regions and noncapsid gene 2A of the four Korean HPeV-A3 strains are closely related to the HPeV-A3 strains isolated in Canada in 2007 (Can82853-01), Japan in 2008 (A308/99), and Taiwan in 2011 (TW-03067-2011) while noncapsid genes P2 (2B-2C) and P3 (3A-3D) are closely related to those of HPeV-A1 strains BNI-788St (Germany in 2008) and TW-71594-2010 (Taiwan in 2010). This first report on the whole-genome analysis of HPeV-A3 in Korea provides insight into the evolving status and pathogenesis of HPeVs in children.

Abstract
The first bovine parechovirus (Bo_ParV) was reported in 2021, and currently, only two nearly complete genome sequences of Bo_ParV are available. In this study, we detected Bo_ParVs in 10 out of 158 bovine fecal samples tested using real-time RT-PCR, and Bo_ParVs were isolated from three of these samples using MA104 cells. Analysis of the P1 region revealed that Bo_ParVs shared high pairwise amino acid sequence similarity (≥ 95.7% identity), suggesting antigenic similarity among Bo_ParVs, whereas nucleotide sequence identity values (≥ 84.8%) indicated more variability. A recombination breakpoint was identified in the 2B region, which may influence the evolution of this virus.

Evolutionary Relationships of Ljungan Virus Variants Circulating in Multi-Host Systems across Europe. Viruses 2021; 13:v13071317. [PMID: 34372523 PMCID: PMC8310206 DOI: 10.3390/v13071317] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2021] [Revised: 07/01/2021] [Accepted: 07/02/2021] [Indexed: 12/12/2022] Open
Abstract
The picornavirus named 'Ljungan virus' (LV, species Parechovirus B) has been detected in a dozen small mammal species from across Europe, but detailed information on its genetic diversity and host specificity is lacking. Here, we analyze the evolutionary relationships of LV variants circulating in free-living mammal populations by comparing the phylogenetics of the VP1 region (encoding the capsid protein and associated with LV serotype) and the 3Dpol region (encoding the RNA polymerase) from 24 LV RNA-positive animals and a fragment of the 5' untranslated region (UTR) sequence (used for defining strains) in sympatric small mammals. We define three new VP1 genotypes: two in bank voles (Myodes glareolus) (genotype 8 from Finland, Sweden, France, and Italy, and genotype 9 from France and Italy) and one in field voles (Microtus arvalis) (genotype 7 from Finland). There are several other indications that LV variants are host-specific, at least in parts of their range. Our results suggest that LV evolution is rapid, ongoing and affected by genetic drift, purifying selection, spillover and host evolutionary history. Although recent studies suggest that LV does not have zoonotic potential, its widespread geographical and host distribution in natural populations of well-characterized small mammals could make it useful as a model for studying RNA virus evolution and transmission.

Abstract
Using viral metagenomics, viral nucleic acid in 30 respiratory secretion samples collected from children with unknown etiological acute respiratory disease were investigated. Sequences showing similarity to human parainfluenza virus 1, anellovirus, bocavirus, coxsackievirus A4, human parechovirus (HPeV), and alphaflexivirus were recovered from these samples. Complete genomes of one anellovirus, one coxsackievirus A4, three parechoviruses were determined from these libraries. The anellovirus (MW267851) phylogenetically clustered with an unpublished anellovirus (MK212032) from respiratory sample of a Vietnamese patient, forming a separate branch neighboring to strains within the genus Betatorquevirus. The genome of coxsackievirus A4 (MW267852) shares the highest sequence identity of 96.4% to a coxsackievirus A4 (MN964079) which was identified in clinical samples from children with Hand, Foot, and Mouth Disease (HFMD). Two (MW267853 and MW267854) of the three parechoviruses belong to HPeV-1 and the other one (MW267855) belongs to HPeV-6. Recombination analysis indicated that an HPeV-1 (MW267854) identified in this study is a putative recombinant occurred between HPeV-1 and HPeV-3. Whether these viruses have association with specific respiratory disease calls for further investigation.

Evolutionary and network analysis of virus sequences from infants infected with an Australian recombinant strain of human parechovirus type 3. Sci Rep 2017.

Abstract
We present the near complete virus genome sequences with phylogenetic and network analyses of potential transmission networks of a total of 18 Australian cases of human parechovirus type 3 (HPeV3) infection in infants in the period from 2012–2015. Overall the results support our previous finding that the Australian outbreak strain/lineage is a result of a major recombination event that took place between March 2012 and November 2013 followed by further virus evolution and possibly recombination. While the nonstructural coding region of unknown provenance appears to evolve significantly both at the nucleotide and amino acid level, the capsid encoding region derived from the Yamagata 2011 lineage of HPeV3 appears to be very stable, particularly at the amino acid level. The phylogenetic and network analyses performed support a temporal evolution from the first Australian recombinant virus sequence from November 2013 to March/April 2014, onto the 2015 outbreak. The 2015 outbreak samples fall into two separate clusters with a possible common ancestor between March/April 2014 and September 2015, with each cluster further evolving in the period from September to November/December 2015.

Abstract
Human parechovirus types 1–16 (HPeV1–16) are positive strand RNA viruses in the family Picornaviridae. We investigated a 2015 outbreak of HPeV3 causing illness in infants in Victoria, Australia. Virus genome was extracted from clinical material and isolates and sequenced using a combination of next generation and Sanger sequencing. The HPeV3 outbreak genome was 98.7% similar to the HPeV3 Yamagata 2011 lineage for the region encoding the structural proteins up to nucleotide position 3115, but downstream of that the genome varied from known HPeV sequences with a similarity of 85% or less. Analysis indicated that recombination had occurred, may have involved multiple types of HPeV and that the recombination event/s occurred between March 2012 and November 2013. However the origin of the genome downstream of the recombination site is unknown. Overall, the capsid of this virus is highly conserved, but recombination provided a different non-structural protein coding region that may convey an evolutionary advantage. The indication that the capsid encoding region is highly conserved at the amino acid level may be helpful in directing energy towards the development of a preventive vaccine for expecting mothers or antibody treatment of young infants with severe disease.

Abstract
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 nucleotide sequence divergence. Phylogenetic analysis based on the complete genomes of these HPeV strains revealed that they belonged to seven different genotypes (including three putative novel genotypes), suggesting that HPeVs showed genotype diversity in this area. Recombination analysis indicated that one of the HPeVs, belonging to HPeV-1 with strain name 146Chzj02, was a recombinant generated by inter-genotype recombination among three HPeV strains belonging to three different genotypes, respectively. CONCLUSION Our data revealed the property of the genotype diversity of HPeVs prevalent in children with diarrhea in eastern China, which will be helpful in the future study of the viral evolution of HPeVs and the identification and typing of HPeVs in the clinical laboratory.

Abstract
Human parechoviruses (HPeVs) were initially classified as echoviruses. HPeVs occur worldwide, comprising up to 17 genotypes. HPeV1 and HPeV3 are most common. Clinical disease varies somewhat among genotypes. HPeV1 causes mostly gastrointestinal infections. HPeV3's prominence is due to its causing sepsis syndromes and central nervous system (CNS) infections in young infants. Currently, HPeV3 is the most common single cause of aseptic meningitis/meningoencephalitis in infants less than 90 days old in North America, usually with biannual summer-fall seasonality. HPeV3 CNS infections usually lack cerebrospinal fluid pleocytosis. Mortality and sequelae are uncommon, usually accompanying initially severe or neurologically complicated acute illnesses.

Abstract
Human parechoviruses (HPeVs) belong to the Parechovirus genus of the large and growing family of Picornaviridae with a non-enveloped, single-stranded and positive-sense RNA. An HPeV strain was isolated from the nasopharyngeal aspirate specimen of a 2 months old infant hospitalized with pneumonia in Beijing, China and nominated as BJ-37359 followed the code of the specimen. Strain BJ-37359 was identified as HPeV1 by whole genome sequencing. The full genome of strain BJ-37359 consisted of 7336 nucleotides (nt), excluding a poly (A) tail and contained an ORF of 6537 nt flanked by 5'UTR of 709 nt and 3'UTR of 90 nt. Phylogenetic analyses revealed that strain BJ-37359 were clustered together with HPeV1 strains in the structural capsid protein region, while uncoupling in the non-structural gene regions. Analyses with Simplot and Bootscan indicated that multiple recombination events occurred in the non-structural region and VP0 region of strain BJ-37359 with other HPeV1, and other types might have contributed to the recombination, especially HPeV6 and HPeV7 strains. Recombination analyses indicated that strain BJ-37359 may have a mosaic genome with new genomic recombination breakpoints.
