Infection of South American coatis (Nasua nasua) with highly pathogenic avian influenza H5N1 virus displaying mammalian adaptive mutations. Microb Pathog 2024; 195:106895. [PMID: 39208965 DOI: 10.1016/j.micpath.2024.106895] [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: 04/16/2024] [Revised: 08/18/2024] [Accepted: 08/26/2024] [Indexed: 09/04/2024]
Abstract
Deadly outbreaks among poultry, wild birds, and carnivorous mammals by the highly pathogenic H5N1 virus of the clade 2.3.4.4b have been reported in South America. The increasing virus incidence in various mammal species poses a severe zoonotic and pandemic threat. In Uruguay, the clade 2.3.4.4b viruses were first detected in February 2023, affecting wild birds and backyard poultry. Three months after the first reported case in Uruguay, the disease affected a population of 23 coatis (Nasua) in an ecological park. Most animals became infected, likely directly or indirectly from wild birds in the park, and experienced sudden death. Five animals from the colony survived, and four of them developed antibodies. The genomes of the H5N1 strains infecting coatis belonged to the B3.2 genotype of the clade 2.3.4.4b. Genomes from coatis were closely associated with those infecting backyard poultry, but transmission likely occurred through wild birds. Notable, two genomes have a 627K substitution in the RNA polymerase PB2 subunit, a hallmark amino acid linked to mammalian adaptation. Our findings support the ability of the avian influenza virus of the 2.3.4.4b clade to infect and transmit among terrestrial mammals with high pathogenicity and undergo rapid adaptive changes. It also highlights the coatis' ability to develop immunity and naturally clear the infection.

Yu Y, Yao Y, Song Y, Shan H, Han X. Establishment and application of multiplex PCR for rapid detection of three mink diarrhea-associated viruses. J Virol Methods 2024; 328:114958. [PMID: 38801834 DOI: 10.1016/j.jviromet.2024.114958] [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: 01/15/2024] [Revised: 05/07/2024] [Accepted: 05/19/2024] [Indexed: 05/29/2024]
Abstract
In this report, a multiplex PCR method was developed for the detection of three diarrhea-associated viruses in mink, including circovirus (MCV), bocavirus (MBoV), and enteritis virus (MEV). Three compatible sets of primers specific for each virus were designed respectively based on their conserved sequences. After optimization of the crucial factors such as primer concentration and annealing temperature in single and multiple amplification, three specific fragments were simultaneously amplified with the highest sensitivity and specificity in one PCR reaction. The fragments amplified were 259 bp (MCV),455 bp (MBoV) and 671 bp (MEV). The sensibility of this one-step multiplex PCR is about 10 times lower than that of regular singleplex PCR. There were no cross-reactions with some relevant pathogens like mink coronavirus, canine distemper virus, and aleutian mink disease virus. In our study we analyzed viral DNA in mink fecal samples by multiplex PCR assay from China, which revealed the occurrence of MCV, MBoV, and MEV as 3.1 %, 5.7 %, and 9.8 %, respectively. The testing results of multiplex PCR agreed with the singleplex PCR results with a coincidence rate of 100 %. These results indicated that the method could provide technical support for rapid detection of the three diarrhea-associated viruses, and epidemiological investigation of mink viral diarrhea.

Abstract
Broad coverage of mink enteritis virus (MEV) vaccination program in northeast of China has provided effective protection from mink viral enteritis. Nevertheless, MEV vaccine failures were reported due to continually evolving and changing virulence of field variants or wild-type MEV. In this study, a combined loop-mediated isothermal amplification (LAMP) and single nucleotide polymorphism (SNP) method, named LAMP-SNP assay, was developed for detection and differentiation of wild-type and vaccine strains of MEV. Four primers in MEV-VP2-LAMP were used to detect both wild-type and vaccine strains of MEV in our previous publication, and other four primers in LAMP-SNP were designed to amplify the NS1 gene in wild-type MEV and only used to detect wild-type viruses. The LAMP-SNP assay was performed in a water bath held at a constant temperature of 65 °C for 60 min. LAMP-SNP amplification can be judged by both electrophoresis and visual assessment with the unaided eyes. In comparison with virus isolation as the gold standard in testing 171 mink samples, the percentage of agreement and relative sensitivity and specificity of the LAMP-SNP assay were 97.1, 100%, and 94.0%, respectively. There were no cross-reactions with other mink viruses. The LAMP-SNP assay was found to be a rapid, reliable and low-cost method to differentiate MEV vaccine and field variant strains.

A multiplex TaqMan real-time PCR for detection and differentiation of four antigenic types of canine parvovirus in China. Mol Cell Probes 2018; 38:7-12. [PMID: 29499233 PMCID: PMC7126752 DOI: 10.1016/j.mcp.2018.02.004] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2017] [Revised: 02/02/2018] [Accepted: 02/26/2018] [Indexed: 12/24/2022]
Abstract
Canine parvovirus (CPV) is an important pathogen in domestic dogs, and the original antigenic types CPV-2 and its variants, CPV-2a, 2b and 2c, are prevalent worldwide. A multiplex TaqMan real-time PCR method was developed for the detection and differentiation of four antigenic types of CPV. A set of primers and probes, CPV-305F/CPV-305R and CPV-2-305P (for CPV-2)/CPV-2a-305P (for CPV-2a, 2b and 2c), was able to differentiate CPV-2 and its variants (CPV-2a, 2b and 2c). Another set of primers and probes, CPV-426F/CPV-426R and CPV-2-426P (for CPV-2 and 2a)/CPV-2b-426P (for CPV-2b)/CPV-2c-426P (for CPV-2c), was able to differentiate CPV-2a (2), CPV-2b, and CPV-2c. With these primers and probes, the multiplex TaqMan real-time PCR assay detected effectively and differentiated CPV-2, 2a, 2b and 2c by two separate real-time PCRs. No cross reactivity was observed with canine distemper virus, canine adenovirus, and canine coronavirus. The detection limit of the assay is 101 genome copies/μL for CPV-2, CPV-2a, CPV-2b, and 102 copies/μL for CPV-2c. The multiplex real-time PCR has 100% agreement with DNA sequencing. We provide a sensitive assay that simultaneously detects and differentiate four antigenic types of CPV and the method was also used for quantification of CPVs viral genome. The Multiplex TaqMan real-time PCR can simultaneously detect and differentiate four antigenic types of CPV. The method is suit for using in detection of CPVs in China. The method showed a high specificity and sensitivity. The method was also used for quantification of CPVs viral genome.

Abstract
A loop-mediated isothermal amplification (LAMP) assay was used for rapid canine parvovirus (CPV) diagnosis. To reduce the time required and increase the sensitivity of the assay, an immunocapture (IC) technique was developed in this study to exclude the DNA extraction step in molecular diagnostic procedures for CPV. A polyclonal rabbit anti-CPV serum was produced against VP2-EpC that was cloned via DNA recombination. The polyclonal anti-VP2-EpC serum was used for virus capture to prepare microtubes. IC-LAMP was performed to amplify a specific CPV target gene sequence from the CPV viral particles that were captured on the microtubes, and the amplicons were analyzed using agarose electrophoresis or enzyme-linked immunosorbent assay (IC-LAMP-ELISA) and lateral-flow dipstick (IC-LAMP-LFD). The detection sensitivities of IC-LAMP, IC-LAMP-ELISA, and IC-LAMP-LFD were 10-1, 10-1, and 10-1 TCID50/mL, respectively. Using the IC-LAMP-ELISA and IC-LAMP-LFD assays, the complete CPV diagnostic process can be achieved within 1.5h. Both of the developed IC-LAMP-based assays are simple, direct visual and efficient techniques that are applicable to the detection of CPV.

Abstract
A restriction fragment length polymorphism combined with direct PCR technique to differentiate goose and Muscovy duck parvoviruses (GPV and MDPV) was developed based on comparison of the NS gene of GPV and MDPV. Both GPV and MDPV genomic DNA can be amplified with 641 bp using the specific PCR primers. The PCR fragments can be cut into 463 bp and 178 bp only in the case of MDPV-derived PCR products, whereas the GPV-derived PCR products cannot. The method established in this study can be used to differentiate GPV and MDPV with high specificity and precision, by using a direct PCR kit and QuickCut enzyme, as quickly as conventional PCR.
