The causes of respiratory illness are mainly bacteria, fungi, mycoplasma, chlamydia, viruses, parasites, irritating gases or aspiration foreign bodies. In particular, the virus is known to cause interstitial pneumonia alone and compete with bacteria and mycoplasma to cause more severe pneumonia. For the purpose of treating respiratory diseases, various methods for increasing the drug concentration at the lesion site by directly administering a therapeutic drug such as an antibacterial agent to the infected site (pathogenic site) have been tried.

DISCLOSURE OF THE INVENTION The present inventors have investigated the above-mentioned vaccine administration method, and found that the subcutaneous or intramuscular injection administration and intranasal spray administration have the same or less prophylactic effect. confirmed. Furthermore, since the intranasal spray administration is in the form of being absorbed via the mucous membrane, it was thought that the preventive effect of the intratracheal spray administration was not much different from that of the intranasal spray administration, but it was safer than that. It was a situation where no attempt was made to examine it from the problem of. In other words, direct administration of the vaccine to the respiratory tract, which is the site of infection of the causative virus, poses a risk as if an infection experiment is being conducted, given the fact that live vaccines are widely used as vaccines.

[0009] Vaccines are those which are administered to cattle to develop active immunity and, as a result, impart resistance (preventive effect) to pathogens or related pathogens. Vaccines are usually produced from pathogenic microorganisms of infectious diseases such as viruses and bacteria and their related microorganisms. Vaccines produced by inactivating raw materials are called inactivated vaccines, vaccines produced without inactivating raw materials are called live vaccines, and usually attenuated strains of pathogens are used. A live vaccine is usually used as a vaccine against respiratory diseases in cattle. Vaccines consist mainly of pathogenic microorganisms, their components, metabolites such as toxins, attenuated strains or closely related microorganisms, and stabilizers, suspending agents, antibiotics, preservatives, surfactants, etc. are added as appropriate. It is then produced by making it into a liquid form with a solution such as sterile water, physiological saline or phosphate buffer, or by making it into a solid form by freeze-drying, etc. Since it is often a solid substance, it may be dissolved when used in the above-mentioned dissolution liquid.

[0013] For administration, the vaccine may be directly administered to the bronchial bifurcation of cattle, and if administered to the upper bronchus, the preventive effect is often not exhibited sufficiently. The vaccine administered to the bronchial branch may be in the form of liquid, but it is particularly preferable that the vaccine is atomized by spraying. The particle size of the fog is not particularly limited, but usually 10 to 2 as the average particle size.

There is a method in which a vaccine is put in a liquid reservoir provided inside the tube of a Teru and administered to the bronchial bifurcation of a cow by the pressure of a jet gas. As the liquid reservoir, the tube may be elongated, and the central portion may be wound a plurality of times to be fixed to form the liquid reservoir, or the middle of the tube may be expanded. You may form a hollow part and use this as a liquid storage part.

The jet gas is not particularly limited as long as it has neither anesthesia nor irritation to living tissues of cattle and has no adverse effect, but normally, nitrogen, carbon dioxide gas, air and the like are exemplified. . The gas injection container is made of metal, glass, resin, etc., but it is necessary to have pressure resistance to fill the gas with a pressure that can inject to the bronchial branching part, which is economical, safe, and easy to handle. Therefore, aluminum is particularly preferable. The internal pressure of the gas in the container is usually about 5 to 8 kg / cm3.

Since the catheter is usually inserted into the bronchial branch from the nasal cavity of a cow, the length of the inserted portion may be at least the length from the nasal cavity of the cow to the bronchial branch, but if it is too long. Since it becomes difficult to handle, it is usually 1.2 to 2 m, preferably about 1.0 to 1.8 m, depending on the age of the cow. Further, the outer diameter is not particularly limited as long as it can be inserted and taken out, but it is necessary that the outer diameter is such that the trachea is not blocked, and usually about 2 to 10 mm. The material is preferably made of resin or rubber because it must have elasticity to some extent without damaging the mucous membrane surface of the respiratory tract of cattle.

After breeding for 10 weeks after administration, the neutralizing antibody titer was measured over time, the number of pneumonia onset was investigated, and the preventive effects against respiratory diseases of the 3 groups were compared and examined. Neutralizing antibody titer is measured according to the neutralization test on page 234-page 236-serum dilution method of Microbiology Practice Guideline (edited by the University of Tokyo Institute of Medical Science, Alumni Association, Maruzen Co., Ltd., 1988). I went. In addition, the device used for intratracheal spray administration is provided with an insertion portion of about 2 m from the tip of a tube (outer diameter; 8 mm) having a nozzle for spraying at the tip, and following the insertion portion,
A device was used in which the tube was wound twice in a circle with a diameter of 30 cm, 10 ml of the vaccine solution was stored in the wound part, and the other end of the tube following the wound part was attached to the opening of an aluminum container containing carbon dioxide gas. I was there. Aluminum container containing carbon dioxide has a diameter of 35 mm and a height of 67 m.
A columnar aluminum container (epoxy resin inner surface coating) having a volume of 55 m and a volume of about 55 ml was prepared by aseptically filling 0.65 g of carbon dioxide gas with a Pamasol gas filling machine (manufactured by Pamasol, Switzerland) (internal pressure was 6.6). ~ 6.8kg / c

In the intratracheal spray administration group, there were no cattle with pneumonia, whereas in the intramuscular administration group, 3 out of 5 animals and in the intranasal spray administration group occurred in 2 out of 5 animals. The group clearly showed excellent preventive effect.
