The susceptibility of Klebsiella pneumoniae strains isolated from the respiratory tract (55), urinary tract (19) and other human body sites (8) to the antibiotics, amoxycillin/clavulanate, cefuroxime, ceftazidime, gentamicin, norfloxacin, colistine, cotrimoxazole and oxolinic acid, as well as their surface hydrophobicity, were studied. The strains expressed a very high sensitivity to the antibiotics (94.7-100%). The surface hydrophobicity of the strains was evaluated by means of three assays and was minimal. The hydrophobicity manifested by adherence to xylene ranged between 0 and 10% for 96.4% of the respiratory strains, and for 100% of the urinary and other sites. Weak binding of Congo red (10-29 micrograms/10(10) cells) showed 96.4% of respiratory isolates as well as 100% of the urinary and other strains. Results of the salt aggregation test showed that 96.4% of respiratory strains and 100% of urinary and other strains aggregated only at 1.5 M, 2 M or higher concentrations.
对从呼吸道（55株）、泌尿道（19株）及其他人体部位（8株）分离出的肺炎克雷伯菌菌株，研究了其对阿莫西林/克拉维酸、头孢呋辛、头孢他啶、庆大霉素、诺氟沙星、黏菌素、复方新诺明和恶喹酸等抗生素的敏感性及其表面疏水性。这些菌株对这些抗生素表现出很高的敏感性（94.7 - 100%）。通过三种测定方法评估了菌株的表面疏水性，结果显示其表面疏水性很低。对于96.4%的呼吸道菌株，以及100%的泌尿道和其他部位菌株，通过二甲苯吸附法测定的疏水性在0至10%之间。96.4%的呼吸道分离株以及100%的泌尿道和其他菌株表现出刚果红弱结合（10 - 29微克/10¹⁰个细胞）。盐聚集试验结果表明，96.4%的呼吸道菌株以及100%的泌尿道和其他菌株仅在1.5M、2M或更高浓度下聚集。
