title: Characteristics of clinical isolates of Pseudomonas aeruginosa. I. Resistance to serum bactericidal effect and production of proteolytic enzymes.
abstract: 136 strains of Pseudomonas aeruginosa were tested for human serum bactericidal effect. Hundred (73%) of clinical isolates were resistant and 36 (27%) were effectively killed by human (undiluted or even 1000 times diluted) serum. Fifty six out of 136 (41.1%) had proteolytic activity and parallelly were resistant to bactericidal activity of normal human serum. Among serum susceptible strains only 6 out of 136 (4.4%) had proteolytic activity.
