Molecular Investigation of Recent Canine Parvovirus-2 (CPV-2) in Italy Revealed Distinct Clustering. Viruses 2022; 14:v14050917. [PMID: 35632660 PMCID: PMC9143876 DOI: 10.3390/v14050917] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Revised: 04/19/2022] [Accepted: 04/26/2022] [Indexed: 01/04/2023] Open
Abstract
Canine parvovirus Type 2 (CPV-2) is a worldwide distributed virus considered the major cause of viral gastroenteritis in dogs. Studies on Italian CPV-2 are restricted to viruses circulating until 2017. Only one study provided more updated information on CPV-2 but was limited to the Sicily region. No information regarding the circulation and genetic characteristics of CPV-2 in Northeast Italy has been made available since 2015. The present study investigated the genetic characteristics of CPV-2 circulating in the dog population of Northeast Italy between 2013 and 2019. The VP2 gene of 67 CPV-2 was sequenced, and phylogenetic analysis was performed to identify patterns of distribution. Phylogenetic and molecular analysis highlighted unique characteristics of Northeast Italian CPV-2 and interestingly depicted typical genetic clustering of the Italian CPV-2 strains, showing the existence of distinct CPV-2 genetic groups. Such analysis provided insights into the origin of some Italian CPV-2 genetic clusters, revealing potential introductions from East European countries and the spread of CPV-2 from South/Central to North Italy. This is the first report that describes the genetic characteristics of recent Italian CPV-2. Tracking the genetic characteristics of CPV-2 nationally and globally may have impact on understanding the evolution and distribution of CPV-2, in particular in light of the current humanitarian emergency involving Ukraine, with the massive and uncontrolled movement of people and pet animals.

Abstract
Canine parvovirus 2 (CPV-2) outbreaks in close quarters such as kennels or shelters can cause substantial case fatality. Thirteen dead Labradors from a secluded kennel of security dogs presented with typical clinical signs and gross pathology of parvovirus infection. Whole genome shotgun sequencing from tissue-extracted genomic DNA detected new CPV-2a as the contributing antigenic variant. Further genotyping using polymerase chain reaction coupled with high-resolution melt assays (PCR-HRM) confirmed new CPV-2a infection in all deceased dogs. PCR-HRM of additional thirty-four clinically suspected dogs suggested that this variant is in wider community circulation, at least in the southeastern part of Bangladesh. We present complete genome sequence of the new CPV-2a variant circulating in the domestic canine population of Bangladesh.

Abstract
Enteritis caused by CPV-2 antigenic variants (CPV-2a, 2b, and 2c) is frequently reported in dogs worldwide leading to significant morbidity and mortality. Here, we describe about a simple, single-step, ARMS-PCR strategy targeting the mutant 426 amino acid of VP2 to differentiate CPV-2 antigenic types. A total of 150 fecal samples were subjected to ARMS-PCR of which 18 were typed as CPV-2a, 79 were typed as CPV-2b, and 6 were typed as CPV-2c. The ARMS-PCR results were validated by randomly sequencing partial VP2 gene of 14 samples. Phylogenetic analysis of partial VP2 gene sequencing of each of the CPV-2 variants revealed that CPV-2a and CPV-2b isolates formed a separate clade of Indian lineage, while CPV-2c shared common evolutionary origin with Asian lineage. The developed technique is first of its kind, one-step, rapid, sequencing independent method for typing of CPV-2 antigenic variants.

Abstract
Canine parvovirus (CPV) is a fast-evolving single-stranded DNA virus that causes severe and fatal gastrointestinal disease in dogs. Lately, several mutations affecting viral protein (VP) capsid resulting in highly pathogenic variants with distinctive immunological and clinicopathological characteristics abound. This study involved screening stools of 44 randomly selected clinical cases of canine gastroenteritis from 4 cities (Ibadan, Jos, Makurdi, and Zaria) in Nigeria for CPV antigen using an on-the-spot immunoassay test kit, as well as, molecular detection of viral nucleic acid by polymerase chain reaction. Subsequently, nucleic acid sequencing of 1195-bp amplicons encompassing the VP2 encoding region was done. The resultant 40 high-quality amino acid sequences obtained were analysed for the identification and grouping of the viruses into their discrete variants - CPV-2a, CPV-2b, or CPV-2c, using key amino acids substitutions - Asn, Asp, or Glu respectively at position 426 of the VP2 gene. One-third (11/40; 27.5%) of the analysed sequences were identified as CPV-2a and two-third (29/40; 72.5%) as CPV-2c. The original CPV and CPV-2b were not detected. Also, the "new CPV-2a variant" with mutation S297A identified had two additional mutations (Y324I and T440A) associated with selective pressure and vaccination failure in their sequences. Similarly, unique CPV-2c mutants carrying genetic markers (S297A, Y324I, and Q370R) that are highly related to CPVs of Asian origin were observed. These findings revealed a high level of divergence of existing CPVs in circulation; suggesting that CPV is rapidly evolving in Nigeria lately.

Abstract
Canine parvovirus (CPV-2) is an enteric virus causing morbidity and mortality in dogs worldwide. Since CPV-2 emerged as canine pathogen, the original CPV-2 strain has constantly evolved, and its primary variants (CPV-2a, CPV-2b, and CPV-2c) co-circulate to varying extents in canine populations worldwide. Thus, rapid and accurate laboratory diagnoses of CPV-2 variants are crucial to monitor CPV-2 evolution. Conventional methods for CPV-2 genotyping are laborious, time consuming, and determining the genotype of a CPV-2 variant often requires two or more reaction tubes. The present study developed a probe-based fluorescence melting curve analysis (FMCA) for genotyping six different CPV-2 variants (original CPV-2, CPV-2a, CPV-2b, CPV-2c, and vaccine strains of CPVpf and CPVint) in a single reaction tube using only two TaqMan probes. One of the TaqMan probes (FAM labeled) was designed to perfectly match with the target sequence of CPV-2a, this probe allows a 1-bp mismatched hybridization with the CPV-2b VP2 gene region (A4062G), and a 2-bp mismatched hybridization for CPV-2c (A4062G and T4064A); Another TaqMan probe (HEX labeled) was produced to perfectly match with the target sequence of original CPV-2, this probe enables 1-bp mismatched hybridization with the other CPV-2 variants (A3045T). Using the two TaqMan probes, all six CPV-2 variants were readily distinguished by their respective melting temperature values in a single reaction tube. The detection limits of this assay were 1–10 copies per reaction for six CPV-2 construction plasmids and no cross reactions were observed with several other common canine viruses. In this assay, co-infected samples were also directly identified via probe-based FMCA without using a mixing control; only a pure control is required. The clinical evaluation of this assay was demonstrated by analyzing 83 clinical fecal samples, among which 41 (49.39%), 8 (9.63%), and 14 (16.87%) samples were found to be positive for CPV-2a, CPV-2b, and CPV-2c, respectively. The concordance rate between probe-based FMCA and Sanger sequencing was 100%. Thus, the duplex FMCA is effective, rapid, simple, high-throughput, and straightforward for genotyping CPV-2 variants, and is useful to effectively diagnose and monitor CPV-2 epidemiology.

Abstract
Vaccination with canine parvovirus-2 (CPV-2) modified live attenuated vaccine remains an effective control strategy for preventing parvovirus induced enteritis in dogs. Virus shedding is a common phenomenon few days after vaccination, possessing a diagnostic dilemma for accurate differentiation of CPV-2 vaccine and wild type field strains. Though several molecular approaches are available for differentiation, the present study focuses on a simple, rapid, cost-effective differentiating infected from vaccinated animals strategy employing ARMS-PCR for differentiation of CPV-2 vaccine and wild type field strains. The ARMS-PCR was initially validated using positive controls of recombinant plasmids, further used for screening six commercial CPV-2 vaccines and 24 archived CPV-2 positive field samples as well as to check fecal shedding of vaccine virus for 10 days post-vaccination in three vaccinated dogs. Sequencing of randomly selected CPV-2 commercial vaccine strains and archived field samples confirmed authenticity of the developed ARMS-PCR assay.

Abstract
Background Canine parvovirus type 2 (CPV‐2) causes an important canine viral disease worldwide. CPV‐2 belongs to the Protoparvovirus genus in the family Parvoviridae. An amino acid change at position 426 of the VP2 protein differentiate types of CPV‐2, designated as CPV‐2a (Asn), CPV‐2b (Asp), and CPV‐2c (Glu). In this study, we compared CPV‐2 genotyping results obtained by SimpleProbe® real‐time PCR and DNA sequencing analysis to identify the accuracy and sensitivity of these methods. Methods One hundred rectal swabs were collected from CPV‐2 naturally infected dogs from 2015 to 2017 at the Animal Disease Diagnostic Center, National Pingtung University of Science and Technology. CPV‐2 genotyping was performed by SimpleProbe® real‐time PCR and DNA sequencing to compare results. Results CPV‐2a (n = 23), 2b (n = 6) and 2c (n = 71) genotyping results obtained by both techniques were identical with specificity of 100% for SimpleProbe® assay. In the SimpleProbe® assay, amplifying the DNAs prepared from the clinical specimens showed three distinct melting curve peaks. CPV‐2b had the highest melting peak of 57.8°C (CI 95%: 57.7‐58.5°C) followed by CPV‐2c with a slightly lower melting peak of 52.3°C (CI 95%: 52.2‐53.2°C) and CPV‐2a with the lowest peak of 50.2°C (CI 95%: 50.1‐50.5°C). Conclusion This study developed a novel method for genotyping CPV‐2 strains using the SimpleProbe® real‐time PCR assay. This assay is a reliable and sensitive tool for differentiating between the CPV‐2a, 2b and 2c and this technique can be used for molecular CPV‐2 epidemiology studies.

Abstract
Differentiation of classical strains and highly pathogenic strains of porcine reproductive and respiratory syndrome virus is crucial for effective vaccination programs and epidemiological studies. We used nested PCR and high resolution melting curve analysis with unlabeled probe to distinguish between the classical and the highly pathogenic strains of this virus. Two sets of primers and a 20 bp unlabeled probe were designed from the NSP3 gene. The unlabeled probe included two mutations specific for the classical and highly pathogenic strains of the virus. An additional primer set from the NSP2 gene of the highly pathogenic vaccine strain JXA1-R was used to detect its exclusive single nucleotide polymorphism. We tested 107 clinical samples, 21 clinical samples were positive for PRRSV (consistent with conventional PCR assay), among them four were positive for the classical strain with the remainder 17 for the highly pathogenic strain. Around 10 °C difference between probe melting temperatures showed the high discriminatory power of this method. Among highly pathogenic positive samples, three samples were determined as positive for JXA1-R vaccine-related strain with a 95% genotype confidence percentage. All these genotyping results using the high resolution melting curve assay were confirmed with DNA sequencing. This unlabeled probe method provides an alternative means to differentiate the classical strains from the highly pathogenic porcine reproductive and respiratory syndrome virus strains rapidly and accurately.

Abstract
Murine parvovirus is one of the most prevalent infectious pathogens in mouse colonies. A specific primer pair targeting the VP2 gene of minute virus of mice (MVM) and mouse parvovirus (MPV) was utilized for high resolution melting (HRM) analysis. The resulting melting curves could distinguish these two virus strains and there was no detectable amplification of the other mouse pathogens which included rat parvovirus (KRV), ectromelia virus (ECT), mouse adenovirus (MAD), mouse cytomegalovirus (MCMV), polyoma virus (Poly), Helicobactor hepaticus (H. hepaticus) and Salmonella typhimurium (S. typhimurium). The detection limit of the standard was 10 copies/μL. This study showed that the PCR-HRM assay could be an alternative useful method with high specificity and sensitivity for differentiating murine parvovirus strains MVM and MPV.

Abstract
BACKGROUND Enterohepatic Helicobacter species (EHS) are widespread in rodent species around the world. Several studies have demonstrated that infection with EHS can interfere with the outcomes of animal experiments in cancer research and significantly influence the study results. Therefore, it is essential to establish a rapid detection and identification of EHS for biomedical research using laboratory rodents. Our study aimed to develop a rapid and sensitive method to detect and distinguish five enterohepatic Helicobacter species. MATERIALS AND METHODS Nested PCR followed by high-resolution melting curve analysis (HRM) was developed for identification of H. bilis, H. rodentium, H. muridarum, H. typhlonius, as well as H. hepaticus. To validate the accuracy of nested PCR-HRM analysis, quantitative real-time PCR methods for five different enterohepatic Helicobacter species were developed. A total of 50 cecal samples were tested using both nested PCR-HRM analysis and qPCR method. RESULTS The nested PCR-HRM method could distinguish five enterohepatic Helicobacter species by different melting temperatures. The melting curve were characterized by peaks of 78.7 ± 0.12°C for H. rodentium, 80.51 ± 0.09°C for H. bilis, 81.6 ± 0.1°C for H. typhlonius, 82.11 ± 0.18°C for H. muridarum, and 82.95 ± 0.09°C for H. hepaticus. CONCLUSIONS The nested PCR-HRM assay is a simple, rapid, and cost-effective assay. This assay could be a useful tool for molecular epidemiology study of enterohepatic Helicobacter infection and an attractive alternative for genotyping of enterohepatic Helicobacter species.

Multiplex Amplification Refractory Mutation System PCR (ARMS-PCR) provides sequencing independent typing of canine parvovirus. INFECTION GENETICS AND EVOLUTION 2016; 46:59-64. [PMID: 27876613 DOI: 10.1016/j.meegid.2016.10.024] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/28/2016] [Revised: 10/27/2016] [Accepted: 10/28/2016] [Indexed: 11/27/2022]
Abstract
Canine parvovirus-2 antigenic variants (CPV-2a, CPV-2b and CPV-2c) ubiquitously distributed worldwide in canine population causes severe fatal gastroenteritis. Antigenic typing of CPV-2 remains a prime focus of research groups worldwide in understanding the disease epidemiology and virus evolution. The present study was thus envisioned to provide a simple sequencing independent, rapid, robust, specific, user-friendly technique for detecting and typing of presently circulating CPV-2 antigenic variants. ARMS-PCR strategy was employed using specific primers for CPV-2a, CPV-2b and CPV-2c to differentiate these antigenic types. ARMS-PCR was initially optimized with reference positive controls in two steps; where first reaction was used to differentiate CPV-2a from CPV-2b/CPV-2c. The second reaction was carried out with CPV-2c specific primers to confirm the presence of CPV-2c. Initial validation of the ARMS-PCR was carried out with 24 sequenced samples and the results were matched with the sequencing results. ARMS-PCR technique was further used to screen and type 90 suspected clinical samples. Randomly selected 15 suspected clinical samples that were typed with this technique were sequenced. The results of ARMS-PCR and the sequencing matched exactly with each other. The developed technique has a potential to become a sequencing independent method for simultaneous detection and typing of CPV-2 antigenic variants in veterinary disease diagnostic laboratories globally.

A high-resolution melting (HRM) assay for the differentiation between Israeli field and Neethling vaccine lumpy skin disease viruses. J Virol Methods 2016; 232:12-5. [PMID: 26902159 DOI: 10.1016/j.jviromet.2016.02.008] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2015] [Revised: 02/17/2016] [Accepted: 02/17/2016] [Indexed: 10/22/2022]
Abstract
Lumpy skin disease (LSD) is a constant threat to the Middle East including the State of Israel. During vaccination programs it is essential for veterinary services and farmers to be able to distinguish between animals affected by the cattle-borne virulent viruses and vaccinated animals, subsequently affected by the vaccine strain. This study describes an improved high resolution-melting (HRM) test that exploits a 27 base pair (bp) fragment of the LSDV126 extracellular enveloped virion (EEV) gene that is present in field viruses but is absent from the Neethling vaccine strain. This difference leads to ∼0.5 °C melting point change in the HRM assay, when testing the quantitative PCR (qPCR) products generated from the virulent field viruses compared to the attenuated vaccine. By exploiting this difference, it could be shown using the newly developed HRM assay that virus isolated from vaccinated cattle that developed disease symptoms behave similarly to vaccine virus control, indicating that the vaccine virus can induce disease symptoms. This assay is not only in full agreement with the previously published PCR gradient and restriction fragment length polymorphism (RFLP) tests but it is faster with, fewer steps, cheaper and dependable.
