Abstract: | We report on the specificity of a monoclonal antibody which reacts with autoclaved extracts of four species of enterococci but does not react to the same extent with similar extracts from two non-enterococcal group D streptococci. The monoclonal antibody also reacts specifically with purified lipoteichoic acid from Streptococcus faecalis but not significantly with purified lipoteichoic acid from the non-enterococcal species Streptococcus bovis and Streptococcus equinus. The specific antigen detected with this antibody could correlate with the definition of the enterococcus subgroup of the streptococci which would provide further evidence that this sub-group is taxonomically distinct from the other group D streptococci. |
