Abstract

As well known, there are many factors in host-parasite relationship which may influence and modify the course of infectious processes. The rate of growth and multiplication of invading organism in a given tissue may be said to be the most important factor in the early stage of many: infectious diseases.
A few reports have been published which implied the occasional presence of microorganisms in the peritoneal fluid of liver cirrhosis patients. They also pointed out that the bacerial peritonitis might be relatively common but rarely recognized.
The author considered it might be worthwhile to observe the fate of microorganisms in the peritoneal fluid from liver cirrhosis patients.
Thus, the bacterial suspensions of Staph. aureus, Staph. albus, B. subtilis, and Es. coli were inoculated into the peritoneal fluid from 7 cases of liver cirrhosis and the viable units of the bacterial species, at 37°C, under aerobic condition, were followed.
Results of the observation were summarized as follow;
1) The viable units of Staph. aureus showed negligible increase in the first 1 hour of incubation, but rapid increase thereafter in all cases.
2) The viable units of Staph. albus showed only slight increase after 1 to 3 hours of incubation in 6 cases and almost no increase up to 8 hours in one case.
3) The viable units of B. subtilis showed no significant increase in 3 cases up to
8 hours of incubation and the rest of 4 cases showed rather decrease.
4) The viable units of Es. coli began to increase significantly within the first 1 hour in 4 cases and in 1 to 3.hours of incubation in 3 cases Rapid increase, even more prominently than Staph. aureus, of viable units were generally noticed.
5) Difference of peritoneal fluid resulted noticeable difference in ´the multiplication pattern of the organisms.
