Crushed bacterial body and compositions thereof

Abstract

A crushed bacterial body can be obtained by culturing a gram-negative bacterium and physically crushing a body of the gram-negative bacterium, comprises all components including immunostimulatory components in the bacterial body, and comprises LPSs having molecular weights of 20,000 or less as active ingredients. The crushed bacterial body is effective as a health food, drug, skin-care product, bath agent, feedstuff for protecting crustaceans, shellfish, fish, poultry, farm animals and pet animals from infections, and a feed additive for growth promotion, and can provide an innate immunostimulatory substance derived from a gram-negative bacterial body having infection-preventing effects and growth promoting effects, an inexpensive and practical microbial crushed bacterial body, and a composition thereof.
