An isothermal nucleic acid amplification-based enzymatic recombinase amplification method for dual detection of porcine epidemic diarrhea virus and porcine rotavirus A. Virology 2024; 594:110062. [PMID: 38522136 DOI: 10.1016/j.virol.2024.110062] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Revised: 03/06/2024] [Accepted: 03/14/2024] [Indexed: 03/26/2024]
Abstract
Viral diarrhea is the predominant digestive tract sickness in piglings, resulting in substantial profit losses in the porcine industry. Porcine rotavirus A (PoRVA) and porcine epidemic diarrhea virus (PEDV) are the main causes of grave gastroenteritis and massive dysentery, especially in piglets. PoRVA and PEDV have high transmissibility, exhibit similar clinical symptoms, and frequently co-occur. Therefore, to avoid financial losses, a quick, highly efficient, objective diagnostic test for the prevention and detection of these diseases is required. Enzymatic recombinase amplification (ERA) is a novel technology based on isothermal nucleic acid amplification. It demonstrates high sensitivity and excellent specificity, with a short processing time and easy operability, compared with other in vitro nucleic acid amplification technologies. In this study, a dual ERA method to detect and distinguish between PEDV and PoRVA nucleic acids was established. The method shows high sensitivity, as the detection limits were 101 copies/μL for both viruses. To test the usefulness of this method in clinical settings, we tested 64 swine clinical samples. Our results were 100% matched with those acquired using a commercially available kit. Therefore, we have successfully developed a dual diagnostic ERA nucleic acids method for detecting and distinguishing between PEDV and PoRVA.

Detection and Molecular Characterization of Adenoviruses in Captive and Free-Roaming African Green Monkeys ( Chlorocebus sabaeus): Evidence for Possible Recombination and Cross-Species Transmission. Viruses 2023; 15:1605. [PMID: 37515291 PMCID: PMC10385324 DOI: 10.3390/v15071605] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Revised: 07/17/2023] [Accepted: 07/19/2023] [Indexed: 07/30/2023] Open
Abstract
In the present study, 31 samples (12 fecal, 9 nasal and 10 rectal swabs) from 28/92 (30.43%, 10 captive and 18 free-roaming African green monkeys (AGMs, Chlorocebus sabaeus)) apparently healthy AGMs in the Caribbean Island of St. Kitts tested positive for adenoviruses (AdVs) by DNA-dependent DNA polymerase (pol)-, or hexon-based screening PCR assays. Based on analysis of partial deduced amino acid sequences of Pol- and hexon- of nine AGM AdVs, at least two AdV genetic variants (group-I: seven AdVs with a Simian mastadenovirus-F (SAdV-F)/SAdV-18-like Pol and hexon, and group-II: two AdVs with a SAdV-F/SAdV-18-like Pol and a Human mastadenovirus-F (HAdV-F)/HAdV-40-like hexon) were identified, which was corroborated by analysis of the nearly complete putative Pol, complete hexon, and partial penton base sequences of a representative group-I (strain KNA-08975), and -II (KNA-S6) AdV. SAdV-F-like AdVs were reported for the first time in free-roaming non-human primates (NHPs) and after ~six decades from captive NHPs. Molecular characterization of KNA-S6 (and the other group-II AdV) indicated possible recombination and cross-species transmission events involving SAdV-F-like and HAdV-F-like viruses, corroborating the hypothesis that the evolutionary pathways of HAdVs and SAdVs are intermingled, complicated by recombination and inter-species transmission events, especially between related AdV species, such as HAdV-F and SAdV-F. To our knowledge, this is the first report on detection and molecular characterization of AdVs in AGMs.

Abstract
Group A rotaviruses of the family Reoviridae is one of the important intestinal pathogens causing diarrhea in piglets and humans. A human-porcine reassortment rotavirus, GDJM1, was identified from outbreak of diarrhea in suckling piglets and it associated with 60.00% (324/540) morbidity and 20.99% (68/324) mortality in Guangdong Province of China in 2022. Thus, to further characterize the evolutionary diversity of GDJM1, all gene segments were analyzed. The genome constellation was G9-P[19]-I5-R1-C1-M1-A8-N1-T1-E1-H1. Nucleotide sequence identity and phylogenetic analyses showed that the VP6, VP7, NSP4 and NSP5 genes of GDJM1 were the most closely related to the respective genes of porcine strains, with the highest homology ranging from 95.65-98.55% identity. The remaining seven genes (VP1-VP4, NSP1-NSP3) were the most closely related to human strains, with the highest homology ranging from 91.83-96.69% similarity. Therefore, it is likely that GDJM1 emerged as the result of genetic reassortment between porcine and human rotaviruses. To our knowledge, this is the first report that a human-porcine reassortment G9P[19] RVA strain has been identified in mainland China, which providing important insights into evolutionary characterization of G9P[19] RVA strain, and reveals that the strain has a potential risk of cross-species transmission.

Abstract
Rotavirus species A (RVA) is a pathogen mainly affecting children under five years old and young animals. The infection produces acute diarrhea in its hosts and, in intensively reared livestock animals, can cause severe economic losses. In this study, we analyzed all RVA genomic constellations described in animal hosts. This review included animal RVA strains in humans. We compiled detection methods, hosts, genotypes and complete genomes. RVA was described in 86 animal species, with 52% (45/86) described by serology, microscopy or the hybridization method; however, strain sequences were not described. All of these reports were carried out between 1980 and 1990. In 48% (41/86) of them, 9251 strain sequences were reported, with 28% being porcine, 27% bovine, 12% equine and 33% from several other animal species. Genomic constellations were performed in 80% (32/40) of hosts. Typical constellation patterns were observed in groups such as birds, domestic animals and artiodactyls. The analysis of the constellations showed RVA's capacity to infect a broad range of species, because there are RVA genotypes (even entire constellations) from animal species which were described in other studies. This suggests that this virus could generate highly virulent variants through gene reassortments and that these strains could be transmitted to humans as a zoonotic disease, making future surveillance necessary for the prevention of future outbreaks.

High Rates of Detection and Molecular Characterization of Porcine Adenovirus Serotype 5 ( Porcine mastadenovirus C) from Diarrheic Pigs. Pathogens 2022; 11:pathogens11101210. [PMID: 36297267 PMCID: PMC9610507 DOI: 10.3390/pathogens11101210] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 10/17/2022] [Accepted: 10/18/2022] [Indexed: 11/16/2022] Open
Abstract
Since the first report on isolation of porcine adenovirus serotype 5 (PAdV-5, species Porcine mastadenovirus C (PAdV-C)) from pigs with respiratory illness in Japan in 1987, PAdV-5 have been detected in a few fecal samples from healthy pigs and in some environmental samples. To date, only a single PAdV-5 strain (isolate HNF-70 from 1987) has been analyzed for the complete genome. We report here high detection rates of PAdV-5 (25.74%, 26/101 fecal samples) in diarrheic pigs at 3 different farms in the Caribbean country of Dominican Republic. After a long gap, the complete deduced amino acid sequences of the DNA-dependent DNA polymerase (pol) and hexon of two PAdV-5 strains (GES7 and Z11) were determined, revealing >99% sequence identities between PAdV-5 strains (HNF-70, GES7 and Z11) detected in different parts of the world and during different time periods (1987, and 2020−2021). By phylogenetic analysis, the putative hexon and pol of HNF-70, GES7 and Z11 exhibited similar clustering patterns, with the PAdV-5 strains forming a tight cluster near ruminant AdVs, distinct from the species PAdV-A and -B. GES7 and Z11 retained the various conserved features present in the putative pol and major late promoter region of HNF-70. Considering the paucity of data on current epidemiological status and genetic diversity of PAdV in porcine populations, our findings warrant similar studies on PAdV-5 and other PAdVs in clinically ill and healthy pigs. To our knowledge, this is the first report on detection and molecular characterization of PAdV-5 (PAdV-C) from diarrheic pigs.

Abstract
Group A rotavirus (RVA) is the most common diarrhea-causing pathogen among humans and animals worldwide. Rotavirus infection in neonatal calves causes major problems in the livestock industry. This study aimed to determine the prevalence and genetic diversity of bovine rotavirus (BoRVA) infections in calves with diarrhea and to perform whole genome analysis of an unusual strain, designated as RVA/Calf-wt/KOR/KNU-GJ2/2020/G5P[7], that was detected in a 2-day-old diarrheic calf. From 459 diarrheic calves aged 1-40 days, fecal samples were collected and BoRVA infections were screened using real-time RT-PCR targeting VP6 gene. BoRVA was detected in 195 (42.4%) samples and was most prevalent in calves aged 1-10 days (47.2%). No significant difference in the BoRVA infection rate was observed between calves born in herds that were (42.1%) and were not (42.6%) vaccinated against BoRVA. A binomial regression analysis revealed that calves aged 1-10 days (95% confidence intervals [CI]:1.18-24.34; P = 0.000) and 11-20 days (95% CI: 0.76-16.83, P = 0.000) had a 5.37- and 3.58-fold higher BoRVA prevalence in comparison to those aged 31-40 days, respectively. The RVA-positive samples were subsequently subjected to amplification of the VP7 and VP4 genes for determining G and P genotypes. Overall, 45 (23.1%, 45/195) and 63 (32.3, 63/195) sequences for VP7 and VP4 were obtained. In this study, four G and three P genotypes were identified. G6 (86.7%) was the most prevalent genotype, followed by G8 (8.9%), G10 (2.2%), and G5 (2.2%). P[5] (92.1%) was the most frequently detected, followed by P[11] (6.3%), and P[7] (1.6%). The G6P[5] (82.2%) is the most common combination found in Korean native calves with diarrhea, whereas G6P[11] (4.4%) and G10P[11] (2.2%) had relatively low prevalence. G8P[5] (8.9%) was identified for the first time in diarrheic calves in the KOR. The uncommon strain KNU-GJ2 exhibited a G5-P[7]-I5-R1-C1-M2-A1-N1-T1-E1-H1 genotype constellation possessing a typical porcine RVA backbone, with the exception of the VP3 gene, which is derived from bovine. Phylogenetically, except for VP3, ten gene segments of KNU-GJ2 were closely related to porcine, porcine-like, and reassortant bovine strains. Interestingly, the VP3-M2 gene of KNU-GJ2 clustered with bovine-like strains as well as reassortant porcine and bovine strains. Comparison of the NSP4s within a species-specific region of amino acids 131-141 demonstrated that KNU-GJ2 belonged to genotype B with porcine RVAs; however, it differed from porcine RVAs by one to three amino acids. The present study is fundamental to understanding the epidemiology and genotypes of circulating RVAs throughout the KOR and underscoring the importance of continuous monitoring and molecular characterization of RVAs circulating within animal populations for future vaccine development.

Abstract
Viruses pose a major threat to animal health worldwide, causing significant mortalities and morbidities in livestock, companion animals and wildlife, with adverse implications on human health, livelihoods, food safety and security, regional/national economies, and biodiversity. The Greater and Lesser Antilles consist of a cluster of islands between the North and South Americas and is habitat to a wide variety of animal species. This review is the first to put together decades of information on different viruses circulating in companion animals, livestock, and wildlife from the Caribbean islands of Greater and Lesser Antilles. Although animal viral diseases have been documented in the Caribbean region since the 1940s, we found that studies on different animal viruses are limited, inconsistent, and scattered. Furthermore, a significant number of the reports were based on serological assays, yielding preliminary data. The available information was assessed to identify knowledge gaps and limitations, and accordingly, recommendations were made, with the overall goal to improve animal health and production, and combat zoonoses in the region.

Abstract
We report the first description of rotavirus A strains in African buffalo (Syncerus caffer). Following RNA extraction from stool samples, cDNA was prepared, followed either by sequence-independent amplification and 454 pyrosequencing or direct sequencing on an Illumina MiSeq platform. RVA/Buffalo-wt/ZAF/4426/2002/G29P[14] exhibited a novel G29P[14] combination and an artiodactyl backbone: I2-R2-C2-M2-A11-N2-T6-E2-H3. RVA/Buffalo-wt/ZAF/1442/2007/G10P[11] also exhibited an artiodactyl backbone: I2-R2-C2-M2-A13-N2-T6-E2-H3. Characterisation of these genome constellations indicate that the two buffalo strains are moderately diverse from each other and related to South African bovine RVA strains. The detection of RVA in buffalo contribute to our understanding of the host range of rotavirus in animals.

Abstract
An unusual group A rotavirus (RVA) strain (RVA/Human-tc/EGY/AS997/2012/G9[14]) was isolated for the first time in a faecal sample from a 6-month-old child who was hospitalized for treatment of acute gastroenteritis in Egypt in 2012. Whole-genome analysis showed that the strain AS997 had a unique genotype constellation: G9-P[14]-I2-R2-C2-M2-A11-N2-T1-E2-H1. Phylogenetic analysis indicated that the strain AS997 had the consensus P[14] genotype constellation with the G9, T1 and H1 reassortment. This suggests either a mixed gene configuration originated from a human Wa-like strain and a P[14]-containing animal virus, or that this P[14] could have been acquired via reassortment of human strains only. The study shows the possible roles of interspecies transmission and multiple reassortment events leading to the generation of novel rotavirus genotypes and underlines the importance of whole-genome characterization of rotavirus strains in surveillance studies.

[PMID: 32473351 DOI: 10.1016/j.meegid.2020.104383] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Revised: 05/19/2020] [Accepted: 05/25/2020] [Indexed: 12/20/2022]
Abstract
We report here high rates (75.38%, 49/65) of detection of genogroup I (GI) PBVs in diarrheic pigs on the Caribbean island of St. Kitts. High quality gene segment-2 sequences encoding a significant region (~350 amino acid (aa) residues) of the putative RNA-dependent RNA polymerase (RdRp) were obtained for 23 PBV strains. The porcine PBV strains from St. Kitts exhibited high genetic diversity among themselves (deduced aa identities of 56-100%) and with other PBVs (maximum deduced aa identities of 64-97%), and retained the three domains that are conserved in putative RdRps of PBVs. The nearly complete gene segment-2 sequence (full-length minus partial 3'- untranslated region) of a porcine PBV strain (strain PO36 from St. Kitts) that is closely related (deduced aa identities of 96-97%) to simian and human GI PBVs was determined using a combination of the non-specific primer-based amplification method and conventional RT-PCR. The complete putative RdRp sequence of strain PO36 preserved the various features that are maintained in PBVs from various species. For the first time, several co-circulating PBV strains from pigs were characterized for a significant region (~350 aa) of the putative RdRp, providing important insights into the genetic diversity of PBVs in a porcine population. Taken together, these observations corroborated growing evidence that PBVs can be highly prevalent and show limited correlation globally with host species or geography. This is the first report on detection of PBVs in pigs from the Caribbean region.

High rates of detection and complete genomic analysis of porcine circovirus 2 (PCV2) in the Lesser Antilles island of St. Kitts: Identification of PCV2b-PCV2d recombinants. Transbound Emerg Dis 2020; 67:2282-2289.

Abstract
Although porcine circovirus 2 (PCV2) is an economically important pathogen of swine, there is a lack of information on PCV2 from the Lesser Antilles. In this retrospective study, we report high rates of detection of PCV2 DNA in porcine faecal (41.3%, 26/63) and kidney (32.8%, 20/61) samples from the Lesser Antilles island of St. Kitts. Most of the PCV2-positive faecal samples were from diarrhoeic piglets (23/26), with 15 animals exhibiting stunted growth and/or weight loss. Although the PCV2-positive kidneys were from slaughter age, clinically healthy pigs, microscopically, various degrees of inflammation (mild, moderate or severe) were observed in 18 kidneys. Rotavirus-A, porcine parvovirus and torque teno sus virus were detected in 2, 4 and 14 PCV2-positive samples, respectively. The complete genomes of 18 St. Kitts PCV2 strains were amplified using three overlapping nested PCR assays designed in the present study. By phylogenetic analysis of PCV2 open reading frame 2 (ORF2) and complete genomes, 15 St. Kitts strains were assigned to genotype PCV2b. The remaining three PCV2 strains were identified as PCV2b-PCV2d recombinants, with the involvement of ORF2 in two of the strains. To our knowledge, this is the first report on detection and genotyping of PCV2 strains from the Lesser Antilles. Considering the significant contributions of pig farming to the regional livestock economy and increasing demand for local pork in the Lesser Antilles, our findings emphasize the importance of future studies on surveillance and genotyping of PCV2 in other Caribbean islands of the region.

Abstract
Evolutionary biology has become one of the imperative determinants explaining the origin of several viruses which were either identified decades back or are recognized lately using metagenomic approaches. Several notifiable emerging viruses like influenza, Severe Acute Respiratory Syndrome (SARS), Middle East Respiratory Syndrome (MERS), Ebola, Hendra, Nipah and Zika viruses have become the leading causes of epidemics and losses thereto in both human and animals. The sufferings are higher due to gastroenteritis causing viruses including Astrovirus, Calicivirus, Enterovirus, Kobuvirus Picobirnavirus, Sapelovirus, Teschovirus, and many more. Notably, the majority of the emerging viruses enclose RNA genome and these are more prone for insertions/mutation in their genome, leading to evolving viral variants. Rapidity in viral evolution becomes a big hitch in the development process of successful vaccines or antiviral. The prominent gastroenteric virus is rotavirus, which is a double-stranded RNA virus with a segmented nature of genome enabling higher reassortment events and generates unusual strains with unique genomic constellations derivative of parental rotavirus strains. Although most rotaviruses appear to be host restricted, the interspecies transmission of rotaviruses has been well documented across the globe. The nocturnal bats have been accepted harbouring many pathogenic viruses and serving as natural reservoirs. Indications are that bats can also harbour rotaviruses, and help in virus spread. The zooanthroponotic and anthropozoonotic potential of rotaviruses has significant implications for rotavirus epidemiology. Hitherto reports confirm infection of humans through rotaviruses of animal origin, exclusively via direct transmission or through gene reassortments between animal and human strain of rotaviruses. There is a need to understand the ecology and evolutionary biology of emerging rotavirus strains to design effective control programs.

Abstract
A high prevalence of G12 rotavirus strains has previously been reported in southern Mozambique. In this study, the full genomes of five Mozambican G12 strains were determined directly from stool using an Illumina Miseq platform. One sample (0060) contained an intergenogroup co-infection of a G12P[8] Wa-like strain and a GXP[14] DS-1-like strain. The sequences of seven genome segments, detected for the GXP[14] strain, clustered with a diverse group of mostly animal strains, suggesting co-infection with a strain of possible animal origin. The stool samples contained G12P[6] rotavirus strains with Wa-like backbones. Phylogenetic analyses of the VP4 and VP7 encoding segments of the G12P[6] strains suggested that they were reassortants containing backbones that are similar to that of the G12P[8] strain. The study confirms previous observations of interspecies transmission and emphasizes the importance of whole-genome sequencing in order to evaluate rotavirus co-infections and reassortants.

Genetic characterization of a novel G9P[23] rotavirus A strain identified in southwestern China with evidence of a reassortment event between human and porcine strains. Arch Virol 2019; 164:1229-1232.

Abstract
Group A rotaviruses (RVAs) are important zoonotic pathogens that cause intestinal disease in humans and other mammals. In this study, the novel strain RVA/Pig/China/SC11/2017/G9P[23](SC11) was isolated from fecal samples from a pig farm in Sichuan province, southwestern China. The complete genome was found to be 18,347 bp in length with 11 segments. The genotype constellation of strain SC11 was G9-P[23]-I12-R1-C1-M1-A1-N1-T1-E1-H1, according to whole-genome sequencing analysis. The VP1, VP2, VP4, VP6, NSP1-NSP3, and NSP5 genes of RVA strain SC11 were found to be closely related to those of porcine and/or porcine-like human RVAs. Meanwhile, the VP7 and NSP4 genes of strain SC11 were closely related to genes of human RVAs. However, it was difficult to pinpoint the porcine or human origin of the VP3 gene of strain SC11 based on the available data. These results showed that SC11 originated from a natural reassortment event between human and pig RVA strains, and crossover points for recombination were identified at nucleotides (nt) 109-806 of NSP2. This is the first report of such a reassortant and recombinant RVA strain in the southwestern region of China.

INFECTION GENETICS AND EVOLUTION 2018; 65:170-186. [PMID: 30055329 DOI: 10.1016/j.meegid.2018.07.014] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/11/2018] [Revised: 07/11/2018] [Accepted: 07/12/2018] [Indexed: 01/22/2023]
Abstract
A human-porcine reassortant rotavirus, strain R1207, was identified from 74 group A rotaviruses detected in 197 (37.6%) stool samples collected from patients who attended a tertiary care hospital in Ragama, Sri Lanka. This is the first report of a human-porcine reassortant rotavirus in Sri Lanka. The patient was a 12-month-old boy who had been hospitalized with fever and acute diarrhea with a duration of 6 days. The family had pigs at home before the birth of this boy. However, the neighbors still practice pig farming. The genotype constellation of R1207 was G4-P[6]-I1-R1-C1-M1-A1-N1-T1-E1-H1. This is based on the assignment of all the eleven gene segments a full genome-based genotyping system. R1207 showed a 4-2-3-2 genomic electrophoretic migration pattern, which is characteristic of group A rotaviruses. Our analyses revealed that five (NSP2, NSP4, VP1, VP2, and VP7) of the 11 genes were closely related to the respective genes of porcine strains. Although the remaining six genes (NSP1, NSP3, NSP5, VP3, VP4, and VP6) were related to human strains, with the exception of the gene sequence of NSP1, all of these human strains were human-porcine reassortants. With a genogroup 1 genetic backbone, this strain was possibly formed via multiple genetic reassortments. We do not know whether this strain is circulating in pigs, as no data are available on porcine rotaviruses in Sri Lanka. Surveillance should be strengthened to determine the epidemiology of this genotype of rotavirus in Sri Lanka and to assess whether the infection was limited or sustained by ongoing human-to-human transmission.
