Description

Novel swine influenza virus A H1N1 and use according to novel swine influenza virus AH1N1

The present invention relates to swine influenza virus A / swine / Korea / GCVP-KS01 / 2009 (H1N1) and its use.

The human influenza A H1N1 virus, including the swine-derived genome, also known as the "pandemic H1N1", has been outbreaks worldwide since April 2009. There is genetic evidence for the swine origin of pandemic H1N1, but no epidemiological evidence has been reported. Pandemic H1N1 infected swine populations were reported in Canada on April 28 in Alberta, May in Manitoba, and 2009. On May 2, 2009, the first Korean case of pandemic H1N1 was officially confirmed from a person arriving from Mexico City on April 26, 2009. Pandemic H1N1 appeared on pig farms and the virus was isolated from pigs in 2009. From the emergence of pandemic H1N1, there have been several experimental infection studies in pigs using pandemic H1N1 human isolates. These experiments showed that the negative symptoms were similar to those of the pigs infected with the classical swine flu virus.

Hereinafter, the present invention will be described in more detail with reference to Examples. However, these examples are for illustrative purposes only and the scope of the present invention is not limited to these examples.

Example  1: Swine Influenza A H1N1  Isolation and Sequencing of Viruses

Pandemic H1N1 on samples from breeding farms with approximately 6000 pigs after monitoring pandemic H1N1 after the first pandemic H1N1 outbreak on a Korean pig farm in December 2009. The pandemic H1N1 virus was tested using real-time RT-PCR (Bionote, Hwasung, Korea) that was specific to, and the result was positive.

Interestingly, the infected pigs had no apparent respiratory symptoms. The farm is also known to be virally negative for Swine Respiratory Syndrome Virus (PRRSV). Virus isolation from lung sample homogenates was attempted using Madin-Darby canine kidney (MDCK) cells and embryonated eggs. The virus was successfully isolated only in MDCK cell line after the second passage. The isolated virus was named A / swine / Korea / GCVP-KS01 / 2009 (H1N1) (hereinafter also referred to as “GCVP-KS01”). This isolate was deposited with the accession number KCTC 11848BP dated January 1, 2011 to the Korea Research Institute of Bioscience and Biotechnology (KRIBB), an international depository under the Butafest Treaty.

Nucleotide sequences of pandemic H1N1 isolated were HA (hemagglutinin) (772 bp), NA (neuraminidase) (791 bp), NP (nucleoprotein) (1226 bp), NS (non-structural protein) (562 bp) and PA ( It was partially sequenced for the RNA polymerase (637 bp) gene and partially for the M (matrix protein) gene. The identified sequences of HA, NA, PA, NS, NP and M are shown in SEQ ID NOs: 1-6, respectively. Sequencing analysis was performed commercially to identify the identity of the isolated virus (Genotech, Daejon, Korea). The nucleotide sequences of GCVP-KS01 were compared with those of other pandemic H1N1 and classical swine H1N1 viruses, and developmental maps were generated for HA and NA genes using the neighbor joining method of the MEGA 4.0 program.

Nucleotide sequences of GCVP-KS01 were 99%, 99.3%, 99.6%, 99.1%, 99.1%, and 99.5 for HA, NA, M, NS, NP, and PA, respectively for the A / California / 04/2009 strain % Similarity was shown. The partial sequence of the NA, HA, PA, NS, NP and M genes of the A / California / 04/2009 strain, comprising the corresponding sequences of the NA, HA, PA, NS, NP and M genes of the isolate, is SEQ ID NO: 7-12, respectively. According to developmental analysis of HA and NA nucleotides, GCVP-KS01 was clustered with pandemic H1N1 virus isolated from humans from 2009 to 2010. Interestingly, the HA gene of pandemic H1N1 virus isolated from humans in Korea was closely related to that of the isolate of the present invention. Previously reported pandemic H1N1 strains isolated from pigs, A / swine / Korea / SCJ01 / 2009, were also grouped into the same group (Song MS et al., J Clin Microbiol. 2010; 48: 3204-3211). In contrast, the classical swine H1N1 virus isolated from pigs before 2009 was classified as a pandemic H1N1 virus of another group (FIG. 1). The limitation of genetic analysis in this study is that complete sequencing of the full length genome is not available. However, the most important genes used, HA and NA, were included to identify influenza virus types, and partial sequencing demonstrated nearly 99% similarity. Despite these caveats, the data from the nucleotide analysis suggest that the influenza H1N1 Korean isolate of swine origin was closely related to pandemic H1N1, but not the classical swine H1N1 influenza virus.

Example  2: Unspecified pathogen  ( specific pathogen free : SPF ) From pig  Swine Influenza A H1N1  Virus Metamorphosis  ( pathogenicity ).

The isolate, designated A / swine / Korea / GCVP-KS01 / 2010 (H1N1), was inoculated nasal to SPF miniature pigs (Medipig, South Korea). Three 5 week old Sinclair miniature pigs were used in this example. Two of them were used for virus inoculation (VI) and one pig was used as a no inoculation (NI) control.

2 mL of virus (2 ⁷ HAU virus, passage level 4) was inoculated intranasally into group VI via the nasal route. The same volume of normal saline was administered to control pigs in the same manner. Clinical symptoms, including temperature and the amount of viral shedding in nasal discharge, were monitored for 8 days post-inoculation (DPI) for 8 days. collected using sterile cotton swabs in nose trills, suspended in 2 mL of phosphate buffered saline (PBS) and used for real-time RT-PCR to check for viral load. All experimental pigs were euthanized and necropsied to perform pathological analysis Serological analysis of blood samples collected on DPI 9 was performed using a commercial ELISA kit for Matrix protein (Bionote, South Korea). All experimental procedures were approved by an independent animal care and use committee, and guidelines from the Green Cross Veterinary Products for the reproduction of pathogenesis in pigs) was respected.

Pigs inoculated with the virus showed coughing and lethargy from DPI 2 days, whereas unvaccinated pigs showed no clinical symptoms during the experiment. Rectal temperature in group VI was significantly higher than in NI group (P <0.01, Tukey's tes). A febrile response was found from Day 1 of DPI in group VI (> 39 ° C.). In particular, rectal temperatures spiked to 39.5 ° C. in all inoculated pigs on DPI 2 (FIG. 2). Virus spillage in group VI was observed in nasal swabs at DPI 1 to DPI 7. When gross lesions were examined during necropsy, focal reddish consolidation was observed in the lungs of the vaccinated pigs and severe suppurative necrotizing bronchopneumonia was found among the microscopic lesions. Antibodies against influenza virus were also detected in group VI and there was no serological evidence for antibodies in NI animals (data not shown).

As predicted based on previous studies, clinical symptoms, including fever and gross-histopathological lesions, were successfully reproduced in the lungs of pandemic H1N1 inoculated SPF pigs. This example validates the pathogenicity reproduction of pig-isolated pandemic H1N1 virus in SPF swine, the potential concern of viral circulation of pandemic H1N1 in pig herds and the new variants of the swine population. The possibility of appearance was demonstrated.
