Abstract

Experimental, ascending acute pyelonephritis in rats was produced by injecting 0 x 5 ml of 10(9) bacteria/ml into the urinary bladder via the urethra. No traumatic manipulation of the ureters of kidneys was necessary. A grading system for kidney lesions based on macro- and microscopical examination was used. The capacity of different Escherichia coli and proteus strains to induce acute pyelonephritis was tested, and the E. coli 06K13H1 strain and the Proteus mirabilis 03H1 strain were especially capable of causing urinary tract infection. For the P. mirabilis 03H1 strain, a dominance of right kidney lesions was noted in contrast to the E. coli 06K13H1 strain which did not show any side preference.

摘要

通过经尿道向膀胱注射0.5毫升每毫升含10⁹个细菌的菌液,在大鼠身上制造了实验性上行性急性肾盂肾炎。无需对输尿管或肾脏进行创伤性操作。采用了基于大体和显微镜检查的肾脏病变分级系统。测试了不同大肠杆菌和变形杆菌菌株诱发急性肾盂肾炎的能力,其中大肠杆菌06K13H1菌株和奇异变形杆菌03H1菌株特别容易引起尿路感染。对于奇异变形杆菌03H1菌株,发现右肾病变占优势,而大肠杆菌06K13H1菌株则没有显示出任何一侧偏好。
