Genetic and antigenic characterization of two diarrhoeicdominant rotavirus A genotypes G3P[12] and G14P[12] circulating in the global equine population. J Gen Virol 2024; 105:002016. [PMID: 39163114 PMCID: PMC11335307 DOI: 10.1099/jgv.0.002016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2024] [Accepted: 07/30/2024] [Indexed: 08/21/2024] Open
Abstract
Equine rotavirus species A (ERVA) G3P[12] and G14P[12] are two dominant genotypes that cause foal diarrhoea with a significant economic impact on the global equine industry. ERVA can also serve as a source of novel (equine-like) rotavirus species A (RVA) reassortants with zoonotic potential as those identified previously in 2013-2019 when equine G3-like RVA was responsible for worldwide outbreaks of severe gastroenteritis and hospitalizations in children. One hurdle to ERVA research is that the standard cell culture system optimized for human rotavirus replication is not efficient for isolating ERVA. Here, using an engineered cell line defective in antiviral innate immunity, we showed that both equine G3P[12] and G14P[12] strains can be rapidly isolated from diarrhoeic foals. The genome sequence analysis revealed that both G3P[12] and G14P[12] strains share the identical genotypic constellation except for VP7 and VP6 segments in which G3P[12] possessed VP7 of genotype G3 and VP6 of genotype I6 and G14P[12] had the combination of VP7 of genotype G14 and VP6 of genotype I2. Further characterization demonstrated that two ERVA genotypes have a limited cross-neutralization. The lack of an in vitro broad cross-protection between both genotypes supported the increased recent diarrhoea outbreaks due to equine G14P[12] in foals born to dams immunized with the inactivated monovalent equine G3P[12] vaccine. Finally, using the structural modelling approach, we provided the genetic basis of the antigenic divergence between ERVA G3P[12] and G14P[12] strains. The results of this study will provide a framework for further investigation of infection biology, pathogenesis and cross-protection of equine rotaviruses.

Abstract
Group A rotaviruses are a well-known cause of viral gastroenteritis in infants and children, as well as in many mammalian species and birds, affecting them at a young age. This group of viruses has a double-stranded, segmented RNA genome with high genetic diversity linked to point mutations, recombination, and, importantly, reassortment. While initial molecular investigations undertaken in the 1900s suggested host range restriction among group A rotaviruses based on the fact that different gene segments were distributed among different animal species, recent molecular surveillance and genome constellation genotyping studies conducted by the Rotavirus Classification Working Group (RCWG) have shown that animal rotaviruses serve as a source of diversification of human rotavirus A, highlighting their zoonotic potential. Rotaviruses occurring in various animal species have been linked with contributing genetic material to human rotaviruses, including horses, with the most recent identification of equine-like G3 rotavirus A infecting children. The goal of this article is to review relevant information related to rotavirus structure/genomic organization, epidemiology (with a focus on human and equine rotavirus A), evolution, inter-species transmission, and the potential zoonotic role of equine and other animal rotaviruses. Diagnostics, surveillance and the current status of human and livestock vaccines against RVA are also reviewed.

Quadruplex Real-Time TaqMan ® RT-qPCR Assay for Differentiation of Equine Group A and B Rotaviruses and Identification of Group A G3 and G14 Genotypes. Viruses 2023; 15:1626.

Abstract
Equine rotavirus A (ERVA) is the leading cause of diarrhea in foals, with G3P[12] and G14P[12] genotypes being the most prevalent. Recently, equine G3-like RVA was recognized as an emerging infection in children, and a group B equine rotavirus (ERVB) was identified as an emergent cause of foal diarrhea in the US. Thus, there is a need to adapt molecular diagnostic tools for improved detection and surveillance to identify emerging strains, understand their molecular epidemiology, and inform future vaccine development. We developed a quadruplex TaqMan® RT-qPCR assay for differentiation of ERVA and ERVB and simultaneous G-typing of ERVA strains, evaluated its analytical and clinical performance, and compared it to (1) a previously established ERVA triplex RT-qPCR assay and (2) standard RT-PCR assay and Sanger sequencing of PCR products. This quadruplex RT-qPCR assay demonstrated high sensitivity (>90%)/specificity (100%) for every target and high overall agreement (>96%). Comparison between the triplex and quadruplex assays revealed only a slightly higher sensitivity for the ERVA NSP3 target using the triplex format (p-value 0.008) while no significant differences were detected for other targets. This quadruplex RT-qPCR assay will significantly enhance rapid surveillance of both ERVA and ERVB circulating and emerging strains with potential for interspecies transmission.

Abstract
Rotaviruses (RVs) are endemic in swine populations, and all swine herds certainly have a history of RV infection and circulation. Rotavirus A (RVA) and C (RVC) are the most common among all RV species reported in swine. RVA was considered most prevalent and pathogenic in swine; however, RVC has been emerging as a significant cause of enteritis in newborn piglets. RV eradication from swine herds is not practically achievable, hence producers’ mainly focus on minimizing the production impact of RV infections by reducing mortality and diarrhea. Since no intra-uterine passage of immunoglobulins occur in swine during gestation, newborn piglets are highly susceptible to RV infection at birth. Boosting lactogenic immunity in gilts by using vaccines and natural planned exposure (NPE) is currently the only way to prevent RV infections in piglets. RVs are highly diverse and multiple RV species have been reported from swine, which also contributes to the difficulties in preventing RV diarrhea in swine herds. Human RV-gut microbiome studies support a link between microbiome composition and oral RV immunogenicity. Such information is completely lacking for RVs in swine. It is not known how RV infection affects the functionality or structure of gut microbiome in swine. In this review, we provide a detailed overview of genotypic diversity of swine RVs, host-ranges, innate and adaptive immune responses to RVs, homotypic and heterotypic immunity to RVs, current methods used for RV management in swine herds, role of maternal immunity in piglet protection, and prospects of investigating swine gut microbiota in providing immunity against rotaviruses.

Abstract
OBJECTIVE To understand the genetic diversity and molecular epidemiology characteristics of group A Rotavirus (RVA) in domestic sewage through next generation sequencing (NGS), and to explore the feasibility and necessity of NGS method for RVA environmental surveillance. METHODS In this study, two sewage samples from Jinan each quarter in 2019 were selected for concentration, RNA extraction, and then RT-PCR reaction. The amplified positive products were subjected to NGS. Finally, the results were analyzed for diversity and phylogeny. RESULTS A total of 9 G-genotypes and 13 P-genotypes were detected. The Simpson diversity indices in autumn and winter were relatively high. Phylogenetic analysis showed that the dominant types G9 and P[8] were closely related to human-derived sequences. CONCLUSIONS This study proves that environmental surveillance as a means to understand the prevalence of RVA in the population is not only feasible but necessary. NGS based environmental surveillance greatly improves our understanding on RVA genetic diversity, and should be encouraged as a sensitive surveillance tool.

Abstract
This review briefly describes the virus classification, clinical signs, epidemiology,
diagnosis, disinfection, and vaccines related equine group A rotavirus (RVA) infection.
Equine RVA is one of the most important pathogens causing diarrhoea in foals. The main
transmission route is faecal–oral, and the clinical signs are diarrhoea, fever, lethargy,
and anorexia (decreased suckling). Some human RVA rapid antigen detection kits based on
the principles of the immunochromatographic assay are useful for the diagnosis of equine
RVA infection. The kits are used in daily clinical practice because of their rapidity and
ease of handling. Equine RVA is a non-enveloped virus and is more resistant to
disinfectants than enveloped viruses such as equine influenza virus and equine
herpesvirus. Although amphoteric soaps and quaternary ammonium compounds are commonly used
in veterinary hygiene, they are generally ineffective against equine RVA. Alcohol
products, aldehydes, and chlorine- and iodine-based compounds are effective against equine
RVA. Inactivated vaccines have been used for equine RVA infection in some countries.
Pregnant mares are intramuscularly inoculated with a vaccine, and thus their colostrum has
abundant antibodies against RVA at the time of birth. According to G and P classification
defined in accordance with the VP7 and VP4 genes, respectively, the predominant equine
RVAs circulating in horse populations globally are G3P[12] and G14P[12] equine RVAs, but
the vaccines contain only the G3P[12] equine RVA strain. Ideally, a G14P[12] equine RVA
should be added as a vaccine strain to obtain a better vaccine effect.

Abstract
A rare genotype G13P[18] group A rotavirus (RVA/Horse-tc/JPN/MK9/2019/G13P[18]) was isolated from a diarrhoeic foal for the first time in 28 years. The genotype constellation of the virus was assigned to G13-P[18]-I6-R9-C9-M6-A6-N9-T12-E14-H11 and was the same as that of the first isolated strain, RVA/Horse-tc/GBR/L338/1991/G13P[18]. Phylogenetic analysis suggests that the virus is related to RVA/Horse-tc/GBR/L338/1991/G13P[18] and is distant from typical equine rotaviruses of the G3P[12] and G14P[12] genotypes.
