Definitions
- the present invention relates to an infection control agent for livestock poultry or seafood, and a method for controlling the infection, comprising as an active ingredient a dead microbial cell of lactic acid bacteria or a combination thereof and chitosan.
- a lactic acid bacteria-containing composition having a pharmacological action on the digestive tract and the like it is known to use chitosan which is a basic polymer substance in order to improve the adhesion of the lactic acid bacteria to the digestive tract (for example, refer to WO99Z64023 pamphlet), lactic acid bacteria-containing composition containing pharmacological action, ingested or administered to increase the pharmacological action against the gastrointestinal tract and Z or genitourinary excretion It is effective to stay in the digestive tract and Z or genitourinary organs for a long time.
- lactic acid bacteria used are live bacteria.
- the method using live bacteria of lactic acid bacteria is not always easy to prepare and store, it has been extremely powerful for general use including price.
- Animal nutrition composition for producing feed with little influence for example, see JP-A-11 32695
- One or more of leaf, DHA, ganoresi-akitin chitosan, chamomile, rice germ fermented product (SOD), or polyphenol is selected from granules and made into individual packaging.
- a dietary supplement for betting (see JP 2003-038 103, where the synergistic effect of lactic acid bacteria and oligosaccharides is specified), as well as health foods containing lactic acid bacteria and chitosan.
- Many foods have been reported (see, for example, JP-A-2002-315536 and JP-A-09-278674), but these are used without exception, and live cells of lactic acid bacteria are used.
- a livestock 'poultry or fish infection control agent containing the processed product and chitosan as active ingredients, and a method for controlling infection using the dead bacteria of lactobacilli or the processed product and chitosan as active ingredients were not known. .
- E. coli disease in swine is roughly classified into E. coli diarrhea, E. coli enterotoxemia, and E. coli sepsis according to the causative mechanism of the causative fungus.
- Infectious protozoa belonging to a specific serotype is the main cause, and enterotoxemia occurs in the weaning period (4 to 12 weeks of age), and the causative bacterium is collectively called enterotoxemic Escherichia coli (ETEEC).
- ETEEC enterotoxemic Escherichia coli
- Toxemia is caused by colonization of ETEEC in the small intestine and the resulting toxin is absorbed, causing damage to the target tissue.
- Edema disease is a disease of Escherichia coli enterotoxicosis.
- the causative organism belongs to a specific serotype, is included in the category of Vero toxin-producing E. coli (VTEC), and edema disease (ED) often occurs sporadically, but sometimes a small outbreak And rarely occurs in 2-3 or 3 week old suckling pigs or adult pigs And, adult pigs takes a chronic course than weaning pigs, characteristics of the occurrence, pig The number in the group suddenly becomes ill and ends in a short period (4 to 15 days), but may repeat again on the same farm, and the incidence is 10-40%.
- VTEC Vero toxin-producing E. coli
- the high mortality rate of 50-90% is often caused by infection with one serotype, but sometimes there are also several types of infection, and serotypes of edema disease (ED) -causing bacteria (0139 , 0141) is common in each country, and experimentally, 10 5 of 0139 was developed by oral administration for 3 days, and transmission usually occurred via feces, aerosol, contaminated feed, etc. Contamination is known to be long-lasting (see, for example, “Clinical and Microbiological” Vol. 23, 843-849, 1996).
