尿路感染症に関する臨床的研究 第2編: 宿主の変化と菌相

Abstract

The relationship between changes in the host and bacterial flora was studied. 1) In acute cystitis, E. coli occupied 52.7% followed by Staph. aureus and epidermidis. There was a significant difference in drug resistance between E. coli and Staphylococci. 2) In secondary infections, so-called low-virulent bacilli were frequently observed, approximately 40 %, particularly after prostatectomy and nephrostomy. Drug resistance in these cases was also striking. 3) In postoperative infections, the bacteria disappeared along with the accomplishment of the repair of the urinary tract. 4) Drug resistance seems to be greatly affected by urinary stasis. For the complete cure of urinary tract infection, urinary stasis has to be removed. In case it cannot be removed, some measures have to be given to the hosts in order to increase their defense against infection. 5) Drug sensitivity of microorganisms was classified into five patterns, 1) contamination bacteria type, 2) staphylococcic type, 3) E. coli type I, 4) E. coli type II and 5) Pseudomonas type.
