Differentiation of Pseudomonas aeruginosa pili based on sequence and B-cell epitope analyses.

abstract：:The membrane-damaging properties on human diploid embryonic lung fibroblasts of streptolysin O (from Streptococcus pyogenes) and theta-toxin (from Clostridium perfringens) were compared. The results are consistent with the suggested mechanism for hemolysis by streptolysin O involving one fixation site and one lytic si...
