Genetic characterization of two G8P[8] rotavirus strains isolated in Guangzhou, China, in 2020/21: evidence of genome reassortment. BMC Infect Dis 2022; 22:579. [PMID: 35764948 PMCID: PMC9238253 DOI: 10.1186/s12879-022-07542-9] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Accepted: 06/14/2022] [Indexed: 11/16/2022] Open
Abstract
Background The G8 rotavirus genotype has been detected frequently in children in many countries and even became the predominant strain in sub-Saharan African countries, while there are currently no reports from China. In this study we described the genetic characteristics and evolutionary relationship between rotavirus strains from Guangzhou in China and the epidemic rotavirus strains derived from GenBank, 2020–2021. Methods Virus isolation and subsequent next-generation sequencing were performed for confirmed G8P[8] specimens. The genetic characteristics and evolutionary relationship were analyzed in comparison with epidemic rotavirus sequences obtained from GenBank. Results The two Guangzhou G8 strains were DS-1-like with the closest genetic distance to strains circulating in Southeast Asia. The VP7 genes of the two strains were derived from a human, not an animal G8 rotavirus. Large genetic distances in several genes suggested that the Guangzhou strains may not have been transmitted directly from Southeast Asian countries, but have emerged following reassortment events. Conclusions We report the whole genome sequence information of G8P[8] rotaviruses recently detected in China; their clinical and epidemiological significance remains to be explored further.

Abstract
The occurrence of enteric viruses in reclaimed wastewater, their removal by efficient treatment processes and the public health hazards associated with their release into the environments are of great significance in environmental microbiology. In this study, TaqMan-based real-time polymerase chain reaction (qPCR) was used to assess the prevalence of human adenovirus (HAdV), rotavirus (RV) and hepatitis A virus (HAV) in the final effluents of two wastewater treatment plants in the Eastern Cape Province, South Africa, over a twelve-month sampling period. The correlation between the concentrations of viruses in the effluents samples and faecal coliform (FC) densities were assessed as to validate the use of FC as microbiological indicator in water quality assessment. HAdV was detected in 62.5 % (30/48) of the samples with concentrations ranging between 8.4 × 101 and 1.0 × 105 genome copies/L while HAV and RV were only detected at concentrations below the set detection limits. FCs densities ranged from 1 to 2.7 × 104 CFU/100 ml. Adenovirus species HAdV-B (serotype 2) and HAdV-F (serotype 41) were detected in 86.7 % (26/30) and 6.7 % (2/30) of the HAdV-positive samples, respectively. No consistent seasonal trend was observed in HAdV concentrations, however, increased concentrations of HAdV were generally observed in the winter months. Also, there was no correlation between the occurrence of HAdV and FC at both the treatment plants. The persistent occurrence of HAdV in the discharged treated effluents points to the potential public health risk through the release of HAdV into the receiving watersheds, and the possibility of their transmission to human population.

Abstract
Although rotavirus vaccines are available, rotaviruses remain the major cause of childhood diarrheal disease worldwide. The Rotarix (GlaxoSmithKline Biologicals Rixensart, Belgium) and RotaTeq (Merck and Co., Inc. Whitehouse Station, New Jersey, USA) vaccines are effective for reducing the morbidity and mortality of rotavirus infection. This article aims to assess the epidemiology of rotaviral gastroenteritis and the efficacy and effectiveness of licensed rotavirus vaccines. This review concludes by presenting challenges in the field that require further exploration by and perspectives from basic and translational research in the future.

Molecular epidemiology and genetic evolution of the whole genome of G3P[8] human rotavirus in Wuhan, China, from 2000 through 2013. PLoS One 2014; 9:e88850. [PMID: 24676363 PMCID: PMC3967987 DOI: 10.1371/journal.pone.0088850] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2013] [Accepted: 01/11/2014] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND Rotaviruses are a major etiologic agent of gastroenteritis in infants and young children worldwide. Since the latter of the 1990s, G3 human rotaviruses referred to as "new variant G3" have emerged and spread in China, being a dominant genotype until 2010, although their genomic evolution has not yet been well investigated. METHODS The complete genomes of 33 G3P[8] human rotavirus strains detected in Wuhan, China, from 2000 through 2013 were analyzed. Phylogenetic trees of concatenated sequences of all the RNA segments and individual genes were constructed together with published rotavirus sequences. RESULTS Genotypes of 11 gene segments of all the 33 strains were assigned to G3-P[8]-I1-R1-C1-M1-A1-N1-T1-E1-H1, belonging to Wa genogroup. Phylogenetic analysis of the concatenated full genome sequences indicated that all the modern G3P[8] strains were assigned to Cluster 2 containing only one clade of G3P[8] strains in the US detected in the 1970s, which was distinct from Cluster 1 comprising most of old G3P[8] strains. While main lineages of all the 11 gene segments persisted during the study period, different lineages appeared occasionally in RNA segments encoding VP1, VP4, VP6, and NSP1-NSP5, exhibiting various allele constellations. In contrast, only a single lineage was detected for VP7, VP2, and VP3 genes. Remarkable lineage shift was observed for NSP1 gene; lineage A1-2 emerged in 2007 and became dominant in 2008-2009 epidemic season, while lineage A1-1 persisted throughout the study period. CONCLUSION Chinese G3P[8] rotavirus strains have evolved since 2000 by intra-genogroup reassortment with co-circulating strains, accumulating more reassorted genes over the years. This is the first large-scale whole genome-based study to assess the long-term evolution of common human rotaviruses (G3P[8]) in an Asian country.

Abstract
Rotavirus evolves by using multiple genetic mechanisms which are an accumulation of spontaneous point mutations and reassortment events. Other mechanisms, such as cross-species transmission and inter-genotype recombination, may be also involved. One of the most interesting genotypes in the accumulation of these events is the G3 genotype. In this work, six new Spanish G3 sequences belonging to 0-2-year-old patients from Madrid were analysed and compared with 160 others of the same genotype obtained from humans and other host species to establish the evolutionary pathways of the G3 genotype. The following results were obtained: (i) there are four different lineages of the G3 genotype which have evolved in different species; (ii) Spanish G3 rotavirus sequences are most similar to the described sequences that belong to lineage I; (iii) several G3 genotype alleles were reassigned as other G genotypes; and (iv) inter-genotype recombination events in G3 viruses involving G1 and G2 were described. These findings strongly suggest multiple inter-species transmission events between different non-human mammalian species and humans.

Abstract
Although G9 rotaviruses have become one of the important rotavirus genotypes worldwide, they have been uncommon in China. Recently, we reported G9 rotaviruses as a highly prevalent genotype in Xinjiang, the northwest part of China [Yang, X., Matthijnssens, J., Sun, H., Muhamaiti, J., Zhang, B., Nahar, S., Van Ranst, M., Rahman, M., 2008. Temporal changes of rotavirus strain distribution in a northwest city of China, 1996-2005. Int. J. Infect. Dis., June (Epub ahead of print)]. Here we report the genetic variations of the Xinjiang-G9 rotaviruses isolated between 1999 and 2005. Sequence analysis of the VP7 genes of Xinjiang-G9 strains indicated that they were more closely related to the contemporary global G9 strains than to the prototype Chinese G9 strains. However, their VP4 genes were most similar to those from the locally circulating G1P[8], G2P[4], G3P[6] and G3P[8] strains. This indicates that reassortment rather than antigenic drift might be the preferred evolutionary mechanism for the emergence of the G9 rotaviruses in Xinjiang. These findings will be of major significance for understanding the emergence of newly introduced rotavirus strains.

Abstract
Since the mid-1990s, novel G9 rotaviruses have been detected in many countries, suggesting that G9 is a globally important serotype. The molecular epidemiology of G9 rotaviruses in Taiwan from 2000 to 2002 was investigated in this study. G9 rotavirus first appeared in 2000 with 4 cases and constituted 33.8% and 54.8% of the rotavirus-positive samples in 2001 and 2002, respectively. These G9 strains belonged to P[8]G9, subgroup II, and long electropherotype, except one belonged to P[4]G9, subgroup II, and short electropherotype. Nucleotide sequencing and phylogenetic analysis of 52 Taiwanese G9 rotaviruses showed that the VP7 genes shared a high degree of identity to overseas G9 rotaviruses detected after 1993 and that the VP8* portions of the VP4 genes were more closely related to those of local rotaviruses of other G types. The two P[8]G9 strains with high nucleotide identities in the VP7 and the partial VP4 genes, 01TW591 of Taiwan from 2001 and 95H115 of Japan from 1995, varied in four genes, genes 2, 3, 7, and 8, which was revealed by RNA-RNA hybridization. Representative strains for different RNA patterns were also analyzed in the partial VP2 and VP3 genes; the nucleotide identities were high between Taiwanese G9 strains and local G3 or G2 strains. These results suggested that Taiwanese G9 rotaviruses possibly had evolved through reassortment between overseas G9 strains and circulating rotaviruses of other G types.
