Abstract

Bovine mastitis is costly infectious disease of dairy cattle, being responsible for significant economic losses all over the world. Also, mastitis has troubled about resistance to antibiotics. The purpose of this study was to screen a novel antimicrobial strain from various sources (raw milk and feeds (from farm of Paju, Dangjin, and Hwasung), commercial milk, Korean traditional fermented foods, and chicken feces). The isolate was screened using triple agar layer method and deferred method was used for confirmation of antimicrobial effect. Seventy six of isolates were screened using triple agar layer method. In these strain, 42 isolates were shown a broad spectrum of autimicrobial activity against mastitis pathogens. Especially, fourteen isolates were shown over 20 mm inhibition zone against S. aureous ATCC 25923. These results suggest that these novel antimicrobial strains could be used for the alternative of antibiotics.

본 연구에서는 원유와 사일리지, 전통발효식품 등으로부터 유방염 원인균에 대한 항균성을 가지는 유산균을 분리하였고, 이들 중 원유에서는 79, 91-3 균주와 전통발효식품에서는 SA131, NK24, NK34, 32, 44-1 균주, 사일리지에서는 253, 261, 262, 263, 265 균주, 닭분변에서 B32, C23 균주에서 유방염 원인균에 대한 비교적 높은 항균력을 확인할 수 있었다. 이를 통해 새로운 항생제 대체물질의 가능성을 확인할 수 있었다.
