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.
对136株铜绿假单胞菌进行了人血清杀菌效果测试。100株（73%）临床分离株耐药，36株（27%）被人（未稀释或甚至稀释1000倍）血清有效杀灭。136株中有56株（41.1%）具有蛋白水解活性，同时对正常人血清的杀菌活性耐药。在血清敏感菌株中，136株中只有6株（4.4%）具有蛋白水解活性。
