A total of 745 P. aeruginosa strains from patients with purulent inflammatory processes, 216 strains from the environment of a surgical hospital and 35 strains from carriers were studied with respect to 30 cultural and biochemical signs of P. aeruginosa. 19.8% of the strains were found to form no pigment, and in 14.8% of the strains delayed pigment formation was observed (on days 3-10). The most stable signs were motility (99.6%), growth in Simmons citrate agar (97.6%), growth at 42 degrees C (97.4%), arginine decarboxylase activity (96.8%). In 77.0% of the strains glucose assimilation in Hiss liquid medium, in 85.6% glucose oxidation in the OF test, in 90.8% the formation of urease and in 93.2% the formation of gelatinase were observed. Among the strains isolated from the environment, P. aeruginosa variants, atypical with respect to their main differentiating signs, were isolated significantly more frequently.
对来自患有化脓性炎症患者的745株铜绿假单胞菌、来自外科医院环境的216株以及来自携带者的35株铜绿假单胞菌，就其30种培养和生化特征进行了研究。发现19.8%的菌株不产生色素，14.8%的菌株观察到色素形成延迟（在第3 - 10天）。最稳定的特征是运动性（99.6%）、在西蒙斯柠檬酸盐琼脂中生长（97.6%）、在42℃生长（97.4%）、精氨酸脱羧酶活性（96.8%）。在77.0%的菌株中观察到在希斯液体培养基中同化葡萄糖，在85.6%的菌株中在氧化发酵试验中氧化葡萄糖，在90.8%的菌株中观察到脲酶形成，在93.2%的菌株中观察到明胶酶形成。在从环境中分离出的菌株中，发现主要鉴别特征非典型的铜绿假单胞菌变种的频率明显更高。
