ADHERENCE OF RUMINAL STREPTOCOCCUS-BOVIS AND LACTOBACILLUS STRAINS TOPRIMARY AND SECONDARY CULTURES OF RUMEN EPITHELIUM

Six strains of rumen Lactobacillus and four Streptococcus bovis strain s isolated from rumen wall and fluid samples were examined for the adh erence to cells of primary and secondary cultures of ruminal epitheliu m (REC) prepared from sheep and calf. S. bovis adhered to the keratini zed REC Ruminal lactobacilli did not adhere. The presence of rumen lac tobacilli in mixture had no influence on the adherence of S. bovis str ains. No difference was observed in the adherence of tested bacteria t o epithelial cells of primary or secondary cultures, but adhesion was only detected on keratinized cells.
