[Comparison of antibacterial potencies of oral and parenteral antibiotic preparations against Escherichia coli, Klebsiella, Citrobacter, and Proteus isolated from urinary tract infections (3. 1981). 3. Patient backgrounds and bacterial sensitivities].

Routine susceptibilities testing of microorganisms isolated from patients are of restricted usefulness in the treatment of patients because of the delay in obtaining results. Thus, the empiric chemotherapy based on the susceptibility of microorganisms isolated from patients is necessary for the majority of patients with simple and complicated urinary tract infections. In this study the relation between changing susceptibility and background factors such as age, a sex distinction, antibiotics, areas in Japan, simple and complicated UTI and so on, has been investigated.

[Immobilization of Citrobacter L-asparaginase in polyacrylamide gel].

Bacterial L-asparaginase, immobilized on polyacrylamide gel, exhibited higher stability to denaturation and to the effect of a proteolytic enzyme. The immobilized enzyme exhibited the pH optimum of activity displaced by one pH unit to the acid side as compared with the free enzyme. The apparent Km value was approximately 200-fold higher as compared with the free L-asparaginase. The immobilized asparaginase hydrolyzed both L- and D-asparagine isomers but the free enzyme was highly stereospecific.

[Citrobacter freundii interaction with epithelial cells and macrophages in vitro].

Electron-microscopic study has revealed the capacity of enteropathogenic C. freundii strain to adhere to the glycocalyx of epithelial HeLa cells, to proliferate on their surface and to induce the toxic damage of their organelles. C. freundii, possessing a fibrillar microcapsule, have been shown to be capable of resisting the action of the lysosome enzymes of guinea-pig macrophages and disorganizing macrophage cultures. The latter fact should be taken into consideration in working with C. freundii strains isolated in the process of diagnostic examination.
