Lactobacillus plantarum 1K FROM “SLAVONSKI KULEN” AS NATURAL PROBIOTIC STARTER CULTURE

The influence of the oral treatment with probiotic strain Lactobacillus plantarum 1K isolated from „Slavonski kulen“ on an oral infection of mice by Salmonella sp. was investigated. Mice were fed with milk-based diets supplemented with L. plantarum 1K for three days prior and following an oral challenge with Salmonella sp. Survival, competition, adhesion and colonization of L. plantarum 1K and influence on infection with Salmonella sp. were monitored in the gastrointestinal tract of mice. After the oral treatment of mice with L. plantarum 1K in combination with Salmonella sp., the total number of lactic acid bacteria in faeces and in intestinal homogenates was increased, contrary, the total number of enterobacteria and Salmonella sp. was reduced. These results demonstrate that L. plantarum 1K can reduce the severity of infection due to the pathogenic Salmonella sp., and suggest that this reduction is associated with competitive exclusion in the intestinal tract. Considering that L. plantarum 1K has demonstrated the basic functional criteria for the selection of probiotic strains, as such, it can be used as functional autochthonous starter culture for fermented meat products.
