Abstract

PURPOSE:To provide the title preventive/therapeutic agent containing bacterial cell-spalled product or cell wall components obtained by fractionation of said spalled product. CONSTITUTION:Cells with high immunoactivation effect for cell-spalled product (e.g. Brevibacterium lactofermesitum ATCC 13869, Bacillus satillus ATCC 13952) are aerobically incubated in an enriched medium of pH 4.0-9.5 at 2-40 deg.C for 12hr to 5 days. The resulting microbial cells are either mechanically spalled using a French press or ultrasonic spalling machine or put to cell wall degradation by the addition of cell wall digesting enzyme (e.g. lysozyme, protease) to obtain a bacterial cell-spalled product. This product is then fractionated by e.g. centrifugation to obtain a cell wall component-containing product. It is appropriate that 0.01-2 (pref. 0.05-1.0)wt.%, on a dry basis, of said cell-spalled product or cell wall component-contg. product be added to a feed and administered.

(Conventional technology and problems) Chicken coccidiosis is caused by the sporozoan Eimeria.
It is a disease of chickens caused by oral infection of several protozoa belonging to the genus a), and is one of the major diseases that causes great economic losses to the poultry industry, especially the broiler industry.

Monenshishi to prevent and treat chicken coccidiosis,
Polyether antibiotics such as salinomycin and lasalocid, or sulfa drugs such as sulfadimethoxy are used, but frequent use of these drugs can lead to the emergence of drug-resistant protozoa, and there is also the problem of the drugs themselves remaining in the body or in chicken egg white. Since their use is severely restricted, the use of these drugs is not effective or safe for the prevention or treatment of chicken coccidiosis. In recent years, progress has been made in the development of live vaccines, but there is still no one that is completely effective.

The method for disrupting the bacterial cells obtained by culture may be either a mechanical method or a method using enzymes. As a mechanical method, for example, using a French press etc.
Cells may be crushed under a pressure of 00 to 2000 kg/C11l, or cells may be crushed using an ultrasonic crusher or the like. When bacterial cells are disrupted using enzymes, cultured bacterial cells or mechanically disrupted cultured bacterial cells are suspended in physiological saline or the like, and a cell wall lytic enzyme is added thereto to decompose the cell walls of the bacterial cells. The enzyme used in this case may be any enzyme as long as it has the ability to decompose cell walls, and representative examples include lysozyme and protease. Enzyme treatment conditions may be according to known methods. In both the mechanical method and the enzymatic method, the cell crushing rate should be about 30% or more (preferably about 60% or more) as measured by the absorbance (wavelength 560 nm) fI & low when suspended in water. By using mechanical methods and enzymatic methods in combination to increase the rate, a cell wall component-containing product with high immunostimulatory effects can be prepared.
