[0003] Canine parainfluenza (CPI) virus causes upper respiratory tract diseases and infectious bronchitis (kennels). It is a highly contagious virus that causes respiratory illnesses, which contribute to the development of cough (also known as flu cough). Respiratory symptoms may resemble those of canine influenza, but they are unrelated viruses. It is a virus and requires different vaccines for protection. The CPI virus lasts for a long time after infection. The virus is excreted from the respiratory tract of infected animals for two weeks and is usually transmitted through airborne transmission. CPI virus The disease spreads rapidly in kennels and defensive facilities where many dogs are kept together. Clinical symptoms Symptoms include a dry or wet cough, a slight fever, a runny nose, lethargy, and loss of appetite.

[0061] Example 1 Administered with or without a bioadhesive polymer or bioadhesive adjuvant. Oral canine parainfluenza virus and B. bronchi Septica) Vaccine efficacy Materials and methods vaccine: The experimental vaccine is a stabilizer solution [hydrolyzed gelatin, NZ amine AS (Millipo Enzymatic hydrolyzate of casein obtained from Sigma, Burlington, MA ) was mixed with sorbitol-d, disodium phosphate and then lyophilized, a non-toxic live B. bronchiseptica antigen B-C2, ATCC deposit number PTA-126272 and modified live CPI virus, strain Cornell, antigen ATC deposit number PTA-126273. The vaccines administered to dogs in treatment groups A, C and D contained 10 - 15% CARBIGEN (trademark) as an adjuvant. The vaccine administered to dogs in treatment group C also contained PVP-K60, a bioadhesive polymer.

[0062] The titer of the CPI virus in the vaccine was 7.5 - 8.5 log 10 HAID 50 / mL and varied, while the titer of B. bronchiseptica (B.bronchiseptica ) in the vaccine varied from 9.2×10 9 to 1.4×10 10 cfu / mL. All vaccines were lyophilized in vials and the lyophilized vaccine in each vial was rehydrated with 1 mL of sterile water on the day of inoculation and similar preparations were pooled. The titer of the CPI virus is provided in log HAID / mL units, which is a unit commonly used to estimate the concentration of the virus in the sample calculated by the Spearman-Karber method. 10 HAID 50 / mL units, which is a unit commonly used to estimate the concentration of the virus in the sample calculated by the Spearman-Karber method. Animals:

[0063] Animals: Seven 10-week-old beagles (Marshall Bioresources) were housed together in BSL-2 facilities on a concrete floor covered with wood shavings. Diet and water were available ad libitum and modified live CPI virus, strain Cornell, antigen ATC deposit number PTA-126273. The vaccines administered to dogs in treatment groups A, C and D contained 10 - 15% CARBIGEN (trademark) as an adjuvant. The vaccine administered to dogs in treatment group C also contained PVP-K60, a bioadhesive polymer. The titer of the CPI virus in the vaccine was 7.5 - 8.5 log HAID / mL and varied, while the titer of B. bronchiseptica (B.bronchiseptica) in the vaccine varied from 9.2×10 to 1.4×10 cfu / mL. All vaccines were lyophilized in vials and the lyophilized vaccine in each vial was rehydrated with 1 mL of sterile water on the day of inoculation and similar preparations were pooled. The titer of the CPI virus is provided in log HAID / mL units, which is a unit commonly used to estimate the concentration of the virus in the sample calculated by the Spearman-Karber method. Animals: Seven 10-week-old beagles (Marshall Bioresources) were housed together in BSL-2 facilities on a concrete floor covered with wood shavings. Diet and water were available ad libitum It should be noted that the original text seems to have some formatting and content issues that made the translation a bit challenging to present cleanly. There are some repeated and overlapping parts in the original that were adjusted as best as possible during translation. I made it possible.

[0064] Vaccination and serum collection: On day 0 of the trial, dogs in treatment group D were given CPI virus and B. bronchiseptica (Bb From ronchiseptica (Bb) and 15% CARBIGEN (trademark name) A 1 mL dose of vaccine was administered orally. A spray device was attached to the syringe. The vaccine was delivered to the back of the throat. On the 14th day of the trial, all dogs were given their respective pools. The vaccine was administered orally [see Table 1 below]. On day 27 of the trial, the jugular vein was vaccinated. Whole blood was collected by pulse puncture. Serum was separated by centrifugation and kept at -10°C or below until testing. It was stored at a specific temperature.

[0065] Detection of CPI virus neutralizing antibodies: CPI virus neutralizing antibodies were detected using a standard serum neutralization (SN) assay. The diluted solution was incubated with the CPI virus vaccine strain and inoculated into canine kidney cells. After 5-7 days, the monolayer was fixed and stained with fluorescein-conjugated CPI virus antiserum. The SN antibody titer is then calculated as the reciprocal of the serum dilution that causes 50% inhibition of viral infection. I calculated it.

[0066] Table 1 Test design [Table 2]

[0067] Challenge: On the 28th day of the experiment, the dogs were administered the toxic CPI virus.

[0068] Post-challenge observations and samples: Clinical observations were recorded for 11 days after the challenge, and daily for 11 days after the challenge. A nasal swab sample was collected.

[0069] result Serology: Prior to vaccination, all dogs had a CPI virus serum neutralizing titer of less than 2. This indicated that the dog had not been infected with the virus at the time of vaccination. The control dogs that received the vaccine remained seronegative (SN<2) until immediately before vaccination. Almost all dogs in the group became serotonically positive for antibodies after vaccination (titer > 4) [see Table 2 below].

[0070] Table 2 Serum antibody titer against CPI virus [Table 3]

[0071] CPI virus shedding: The duration of CPI virus shedding was a key variable for evaluating vaccine efficacy. For each animal, the period of viral shedding from the first to the last dose was calculated in days, and each treatment group was assigned... The average shedding period was calculated. The average viral shedding period for the placebo-vaccinated control group was 7 It was 0 days. In contrast, the average elimination period for treatment groups A and C was 0 days, but for treatment groups B and The average discharge period for D was 1 day [see Table 3 below].

[0072] Table 3 Emission period [Table 4]

[0073] These results indicate that CARBIGEN (trademark) and PVP-K60 are effective in vaccinated dogs. This indicates that it had little effect on the CPI virus shedding period.

I attached a spray device to the syringe and injected it into the back of my throat. The vaccine was delivered. On the 27th day of the trial, whole blood was collected by jugular vein puncture. Serum The components were separated by centrifugation and stored at a temperature of -10°C or below until testing.

[0077] Detection of CPI virus neutralizing antibodies: CPI virus neutralizing antibodies were detected using a standard SN assay. Serum dilutions were then collected in C The PI virus vaccine strain was incubated with the vaccine strain and inoculated into canine kidney cells. (5-7 days) Next, the monolayer was fixed, stained with fluorescein-conjugated CPI virus antiserum, and the SN antibody titer was measured. This was calculated as the reciprocal of the serum dilution that causes 50% inhibition of viral infection.

[0078] Challenge: On the 28th day of the experiment, the dogs were administered the toxic CPI virus.

[0079] Post-challenge observations and samples: Clinical observations were recorded for 14 consecutive days, and nasal swab samples were collected for 10 consecutive days after the challenge. We collected it.

[0080] Table 4 Test design [Table 5]

[0081] result Serology: Prior to vaccination, all dogs had a CPI virus serum neutralizing titer of less than 2. This indicated that the dog had not been infected with the virus at the time of vaccination. The control dogs that received the vaccine remained seronegative (SN<2) until immediately before vaccination. Almost all dogs in the group became serotonically positive for antibodies after vaccination (titer > 4) [see Table 5 below].

[0082] Table 5 Serum antibody titer against CPI virus [Table 6]

[0083] CPI virus shedding: The duration of CPI virus shedding was a key variable for evaluating vaccine efficacy.

[0099] Example 4 Oral canine parainfluenza and Bordetella bronchiseptica combined vaccine Bordetella Immunogenicity study to demonstrate the efficacy of the Terra bronchiseptica fraction Materials and methods vaccine: The experimental vaccine is a modified live CPI virus strain, Cornell, ATCC accession number PTA- 126273 and the non-toxic form of B. bronchiseptica It consists of antigen B-C2 (ATCC accession number PTA-126272), and is stable to it. Consolidating agent [hydrolyzed gelatin, NZ amine AS, sorbitol-d, disodium phosphate] The placebo vaccine was a mixture of [ ] and freeze-dried. (B. bronchiseptica) consists of all components of the test vaccine, excluding the antigen. On the day of vaccination, each freeze-dried vaccine vial was rehydrated with sterile water. They pooled similar preparations.

[0100] animal: 21 seven-week-old beagles were kept together in a BSL-2 facility on a concrete floor covered with wood chips. They were raised in the same way, with 21 seven-week-old beagles being kept in a separate room. Food and water were freely available to them. I made it possible.

[0101] Vaccination: On day 0 of the trial, dogs were given their individual pooled vaccine doses of 1 mL via oral route. Then I got vaccinated [see Table 10 below]. I attached a spray device to the syringe and then... The vaccine was delivered deep into the oropharynx.

[0102] Sample collection: On the 34th day of the experiment, whole blood was collected by venipuncture of the jugular vein. The serum was separated by centrifugation. Separate the samples and store them at a temperature below -10°C until the test. B. bronc To check for the presence of hiseptica, a nasal swab was also collected on day 34 of the experiment. The swab was then placed in a wheel pack bag and immediately inspected.

[0103] Detection of agglutinating antibodies against B. bronchiseptica: Using a standard micro-aggregation test, B. bronchiseptica ICA antibodies were detected. That is, in the test serum, known positive serum, and known negative serum... For a 2x serial dilution, use regular physiological saline containing 0.1% gelatin as a diluent, and apply a U-bottom m The procedure was performed using an ichrotator plate. (B. bronchisept) Add 100 μL of antigen to each well and mix in a microtiter plate mixer. Mix for 5-30 seconds. Incubate the plate at 36±2°C for 1-3 hours, then 2 The plates were incubated at ~7°C for 36-72 hours. The titer was read visually from the plates for aggregation. This was expressed as the reciprocal of the highest dilution that exhibited complete aggregation.

[0104] Challenge: On the 35th day of the experiment, dogs were given the toxic B. bronchiseptic. a) was administered.

[0105] Post-challenge observations and samples: Clinical signs including (but not limited to) runny nose, shortness of breath, depression, and cough. Regarding this, observe the dog twice a day for at least 30 minutes for 28 days after the challenge. Nasal swabs were collected on days 42, 45, 49, 52, 58, and 63 of the experiment. The excretion of administered microorganisms was measured.

[0106] Table 10 Test design [Table 11]

[0107] result Serology: Before vaccination, all dogs were infected with B. bronchisep The dog had a low antibody titer (≤4) against tica, which indicates that the dog had not been vaccinated. This indicates that the individual had not been infected with the virus at the time of inoculation. Of the 21 dogs, 20 were infected with B. bronchiseptica. ) Cohesive titer was induced, ranging from 16 to 128 on day 34 of the experiment; GMT = < 39. In contrast, antibody titers in placebo-vaccinated control dogs were low, ranging from <2 to 8. The temperature remained constant, and GMT = < 1 [see Table 11 below].

[0108] Table 11 B. bronchiseptica serum antibody titer [Table 12]

[0109] Clinical signs after the challenge: After the challenge, all placebo-vaccinated control dogs were tested for B. bronchiseptica ( Clinical signs associated with B. bronchiseptica infection, particularly the development of a spontaneous cough. Infected dogs exhibit spontaneous coughing or vomiting accompanied by spontaneous coughing on two or more consecutive days during the observation period after administration. It was defined as having the condition. All 20 placebo-vaccinated control dogs were affected. In contrast, only 9 out of 21 vaccinated control dogs (43%) developed the disease; p-value < 0.00 01 [See Table 12 below]. Furthermore, during the observation period after administration, if a patient coughed at least once on two consecutive days, No dogs were vaccinated with Kuching, but 18 out of 20 control dogs (90%) received the placebo vaccine. ) coughed 2 to 13 times for two consecutive days.

[0110] Table 12 Summary of dogs that have contracted the disease [Table 13]

[0111] In addition, the number of days on which dogs spontaneously coughed during the 28-day post-treatment observation period was analyzed. Treatment group The average number of days that dogs in group B spontaneously coughed was 16.6 days, compared to the dogs in treatment group A. The response time was only 3.5 days; p-value < 0.0001 [see Table 13 below].

[0113] B. bronchiseptica excretion: Nasal swabs are collected twice a week for four weeks after administration to remove the administered microorganisms. The following was measured. On day 42 of the trial, bacterial levels were observed between the placebo control group and the vaccine group. There was no difference in excretion. However, by the 45th day of the trial, the placebo vaccine control group had 3 B. bronchiseptica at 8,141 cfu / mL The vaccine group excreted 1,523 cfu / mL, but the vaccinated group excreted only 1,523 cfu / mL. In the control group vaccinated against the vovirus, bacterial shedding was 75,293 at 16 days post-vaccination (day 52 of the trial). The peak cfu / mL was reached. In contrast, bacterial shedding in the vaccinated group was observed 6 days after vaccination. The peak occurred on day 42, but it was only 4,173 cfu / mL. Bacterial consultation The number of cases continued to decrease in the vaccinated group until the end of the trial. By day 63 of the trial, the number of cases was... Bacterial shedding in the inoculated group was only 6 cfu / mL, compared to the placebo-inoculated control group. Within the system, bacterial excretion remained high at 35,400 cfu / mL.

[0114] These data suggest that B. bronchiseptica is a species of [unclear]. The group inoculated with kuchin showed a significant decrease in its ability to form colonies in the nasal mucosa. The overall mean bacterial shedding in the SEV1-vaccinated control group and the SEV1-vaccinated group was 37, respectively. The levels were 035 cfu / mL and 849 cfu / mL [see Table 14 below], and on each collection day The amount of B. bronchiseptica excreted is determined by the vaccine. The group that received the vaccine had statistically lower levels than the placebo control group (p-value ≤ 0.00). 01).
