An Improved Duplex Real-Time Quantitative RT-PCR Assay with a Canine Endogenous Internal Positive Control for More Sensitive and Reliable Detection of Canine Parainfluenza Virus 5. Vet Sci 2023; 10:vetsci10020142. [PMID: 36851445 PMCID: PMC9965950 DOI: 10.3390/vetsci10020142] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Revised: 02/04/2023] [Accepted: 02/09/2023] [Indexed: 02/12/2023] Open
Abstract
A duplex real-time quantitative reverse transcription-polymerase chain reaction (dqRT-PCR) assay was successfully developed to simultaneously detect canine parainfluenza virus 5 (CPIV5) and a canine endogenous internal positive control (EIPC) in canine clinical samples. Two sets of primers and probes for the CPIV5 L and canine 16S rRNA genes were included in the dqRT-PCR assay to detect CPIV and monitor invalid results throughout the qRT-PCR process. The developed dqRT-PCR assay specifically detected CPIV5 but no other canine pathogens. Furthermore, 16S rRNA was stably amplified by dqRT-PCR assay in all samples containing canine cellular materials. The assay's sensitivity was determined as below ten RNA copies per reaction, with CPIV5 L gene standard RNA and 1 TCID50/mL with the CPIV5 D008 vaccine strain, which was 10-fold higher than that of the previous HN gene-specific qRT-PCR (HN-qRT-PCR) assays and was equivalent to that of the previous N gene-specific qRT-PCR (N-qRT-PCR) assays, respectively. Moreover, the Ct values of the CPIV5-positive samples obtained using the dqRT-PCR assay were lower than those obtained using the previous HN- and N-qRT-PCR assays, indicating that the diagnostic performance of the dqRT-PCR assay was superior to those of previous HN- and N-qRT-PCR assays. The calculated Cohen's kappa coefficient values (95% confidence interval) between dqRT-PCR and the HN- or N-specific qRT-PCR assays were 0.97 (0.90-1.03) or 1.00 (1.00-1.00), respectively. In conclusion, the newly developed dqRT-PCR assay with high sensitivity, specificity, and reliability will be a promising diagnostic tool for the detection of CPIV5 in clinical samples and useful for etiological and epidemiological studies of CPIV5 infection in dogs.

Transbound Emerg Dis 2022; 69:3300-3316.

Abstract
The number of parainfluenza virus 5 (PIV5) infection cases has increased worldwide over the past six decades; however, factors underlying this increase remain unclear. PIV5 has been emerging or re-emerging in humans and animal species. To date, no information is yet available regarding PIV5 infection in arthropod ticks. Here, we successfully isolated tick-derived PIV5 from the Ixodes persulcatus species designated as HLJ/Tick/2019 in Heilongjiang, China. Phylogenetic analysis revealed that the tick-derived PIV5 is closely related to subclade 2.2.6, which has become the dominant subtype prevalent in dogs, pigs and wildlife across China. Further experiments to understand the importance of this virus as an infectious vector revealed that a ferret animal model experimentally infected with Tick/HLJ/2019 via the oronasal and ocular inoculation routes developed moderate respiratory distress with pneumonia and neurologic tissue damage from inflammation for the first time. Further surveillance of PIV5 in vectors of viral transmission is necessary to enhance our knowledge of its ecology in reservoirs and facilitate the control of re-emerging diseases.

Abstract
During a surveillance study to monitor porcine epidemic diarrohoea virus and transmissible gastroenteritis virus in India, a total of 1043 swine samples including faeces (n = 264) and clotted blood (n = 779) were collected and tested. Five samples (four faecal and one serum) showed cytopathic effects in Vero cells. Transmission electron microscopy of infectious cell supernatant revealed the presence of two types of virions. Next-generation sequencing (de novo) allowed the complete genome sequence of mammalian orthorubulavirus 5 (MRuV5; 15246 bp) and that of all 10 gene segments of mammalian orthoreovirus to be determined. Genetic analysis of MRuV5 revealed grouping of the Indian MRuV5 with isolates from various mammalian species in South Korea and China, sharing more than 99% nucleotide sequence identity. The deduced amino acid sequences of the HN, NP, and F genes of MRuV5 isolates showed three (92L, 111R, 447H), two (86S, 121S), and two (139T, 246T) amino acid substitutions, respectively, compared to previously reported virus strains. Phylogenic analysis based on S1 gene sequences showed the Indian MRV isolates to be clustered in lineage IV of MRV type 3, with the highest nucleotide sequence identity (97.73%) to MRV3 strain ZJ2013, isolated from pigs in China. The protein encoded by the MRV3 S1 gene was found to contain the amino acid residues 198-204NLAIRLP, 249I, 340D, and 419E, which are known to be involved in sialic acid binding and neurotropism. This is the first report of co-isolation and whole-genomic characterisation of MRuV5 and MRV3 in domestic pigs in India. The present study lays a foundation for further surveillance studies and continuous monitoring of the emergence and spread of evolving viruses that might have pathogenic potential in animal and human hosts.

Abstract
Parainfluenza virus 5 (PIV5) belongs to the genus Orthorubulavirus in the family Paramyxoviridae. PIV5 can infect a range of mammals, but induce mild or even unobservable clinical signs in some animals, except kennel cough in dogs. It is also able to infect a variety of cell lines, but causes minimal or even invisible cytopathic effects on many cells. Sometimes, owing to neither observable cytopathic effects in vitro nor typical clinical signs in vivo, the PIV5 is not easily usable for screening antiviral drugs. To solve this issue, we used reverse genetics to recover a dual reporter-tagged recombinant PIV5 that could simultaneously express enhanced green fluorescence protein (eGFP) and NanoLuc® luciferase (NLuc) in virus-infected cells. Both reporters were genetically stable during twenty serial passages of virus in MDBK cells. The eGFP allowed us to observe virus-infected MDBK cells in real time, and moreover the NLuc made it possible to quantify the degree of viral replication for determining antiviral activity of a given drug. Subsequently, the recombinant PIV5 was used for antiviral assays on five common drugs, i.e., ribavirin, apigenin, 1-adamantylamine hydrochloride, moroxydine hydrochloride and tea polyphenol. The results showed that only the ribavirin had an anti-PIV5 effect in MDBK cells. This study proposed a novel method for rapid screening (or prescreening) of anti-PIV5 drugs.

Abstract
Parainfluenza virus type 5 (PIV-5) causes respiratory infection in several animal species and humans. Canine parainfluenza virus type 5 (CPIV-5) causes respiratory disease in domestic dogs worldwide. In this study, we conducted a cross-sectional survey of CPIV-5 in dogs with respiratory symptoms from small animal hospitals in Thailand from November 2015 to December 2018. Our results showed that 32 out of 571 nasal swab samples (5.6%) were positive for CPIV-5 by RT-PCR specific to the NP gene. To characterize the viruses, three representative CPIV-5 were subjected to whole genome sequencing, and an additional ten CPIV-5 were subjected to HN, F, SH and V/P gene sequencing. Pairwise sequence comparison and phylogenetic analysis showed that Thai CPIV-5 was closely related to the CPIV-5 isolated from China and Korea. In conclusion, this study constitutes a whole genome characterization of CPIV-5 from dogs in Thailand. The surveillance of CPIV-5 should be further investigated at a larger scale to determine the dynamics, distribution and potential zoonotic transmission of CPIV-5.

Abstract
Eighteen canine distemper virus (CDV) isolates were obtained from clinical samples in Henan province, China, between 2012 and 2016. These viruses could not be recognized by 1A4, a monoclonal antibody specific for the H protein of CDV vaccine strains. The complete haemagglutinin (H) genes of all 18 isolates were sequenced, and phylogenetic analysis showed that they segregated into two clusters within the Asia-1 genotype. Moreover, the H genes of four viruses were found to lack a potential N-glycosylation site at position 309, which is the most conserved site within the Asia-1 genotype of CDV, and a novel potential N-glycosylation site (amino acids 517–519) was found in strain HL013, which has not been reported previously. These results will help in achieving a better understanding of the evolution of CDV in China.

Abstract
AIMS To determine which of the common canine respiratory pathogens circulate among selected populations of healthy and diseased dogs in New Zealand. METHODS Coagulated blood samples for serology and oropharyngeal swabs for virology were collected from healthy dogs (n=47) and from dogs with acute respiratory disease (n=49). For diseased dogs a convalescent blood sample was also collected 3-4 weeks later. Oropharyngeal swabs were subjected to virus isolation and tested for canine parainfluenza virus (CPIV), canine adenovirus (CAdV) 2, canine herpesvirus (CHV), canine respiratory coronavirus (CRCoV), canine influenza virus (CIV), canine distemper virus (CDV), Bordetella bronchiseptica, Streptococcus equi subsp. zooepidemicus, and Mycoplasma cynos nucleic acids by quantitative PCR (qPCR). Sera were tested for CRCoV antibody using competitive ELISA and results expressed as percent of inhibition (POI). RESULTS The mean age of diseased dogs (2.7, min <0.5, max 8.5 years) was lower than the mean age of healthy dogs (5.3, min <0.5, max 17 years) (p<0.001). In total, 20/94 (21%) dogs were positive for at least one agent by qPCR. Diseased dogs were most commonly positive for M. cynos (8/47, 17%), followed by CPIV (3/47, 6%) and B. bronchiseptica (3/47, 6%), while healthy dogs were most commonly positive for CAdV-2 (6/47, 13%), followed by M. cynos (2/47, 4%). All samples were negative for CIV, CRCoV, CDV and S. equi subsp. zooepidemicus. Viruses were not isolated from any of the samples tested. In total, 47/93 (50%) dogs were seropositive for CRCoV on at least one sampling occasion. Samples from diseased dogs were more frequently seropositive for CRCoV, with higher POI, than samples from healthy dogs. CONCLUSIONS AND CLINICAL RELEVANCE We showed that CAdV-2, CPIV, CHV, CRCoV, B. bronchiseptica and M. cynos circulated among sampled dogs. The convenience sampling methodology, with a poor match between the populations of diseased and healthy dogs in terms of age, breed and use, together with the relatively small sample size precluded inference of any causal relationships between infection with a given pathogen and development of disease. None-the-less, our data suggest that further investigation into epidemiology and disease association of CRCoV and M. cynos is warranted. In addition, circulation of novel respiratory pathogens among dogs in New Zealand should be considered in future studies, as 70/94 (74%) diseased dogs were negative for all the pathogens tested.

Abstract
Recently, parainfluenza virus 5 (PIV5) infection has been increasingly reported in
mammals. In this study, five PIV5 strains were isolated from diarrhea-affected piglets
from four provinces or municipalities in China. An F-gene-based phylogenetic tree
indicated that the five isolated strains were closely related to the PIV5 strain ZJQ-221
from a lesser panda in China, and the PIV5 strain 1168-1 from a dog in South Korea. The
new isolates differed genetically from other pig, calf, rhesus macaque kidney cells,
human, and dog PIV5 reference strains. Our study reveals the presence of PIV5 in
intestinal tissue samples collected from diarrhea-affected piglets, and provides novel
information regarding the epidemiology and tissue tropism of PIV5.
