bladder instillations with trimethoprim-sulfamethoxazole in the treatment of urinary infection.205 paraplegic inpatients with urinary infections were treated with trimethoprim-sulfamethoxazole (tmp-smz) bladder instillations (160 mg tmp 800 mg smz daily for 2 consecutive weeks). 89.3% out of 84 patients with recent vertebral trauma and no history of previous urinary infection (group a), and 68.6% out of 121 patients with paraplegia since more than 2 years, severe chronic infection and various pathological conditions of the urinary tract (group b) were found to be sterile at the end of the ...1978338266
reconstitution of model membranes from phospholipid and outer membrane proteins of proteus mirabilis. role of proteins in the formation of hydrophilic pores and protection of membranes against detergents.outer membrane proteins extracted from isolated cell walls of proteus mirabilis were able to combine the cell wall phospholipids in a model membrane system. the presence of outer membrane proteins in vesicular model membranes mediated the release of previously entrapped [14c]sucrose while [3h]inulin was retained. incorporation of lipopolysaccharide from the same cell walls was not required for the formation of such selectively permeable membranes. three major outer membrane proteins of apparent ...1977338302
nocardicin a, a new monocyclic beta-lactam antibiotic v. in vivo evaluation.nocardicin a is a new monocyclic beta-lactam antibiotic which provides a potent therapeutic effect in mice experimentally infected with gram-negative bacilli. when given subcutaneously to mice, the therapeutic effect of the drug was stronger than had been anticipated from in vitro studies. nocardicin a was more potent in therapeutic effect than carbenicillin against infections due to pseudomonas aeruginosa, proteus mirabilis, pr. vulgaris, pr. rettgeri and pr. inconstans, and was similar in effe ...1977338567

an experimental study on the pathogenesis of sporadic bacteriuria in the experimental model is used in which one ureter of a rat is ligated with the object of forming a hydronephrosis from which urine specimens can subsequently be collected. ascending urinary infection from the bladder is excluded by the ligation. the investigations with this experimental model showed that growth of intestinal bacteria occasionally occurred in culture of urine obtained from the occluded renal pelvis. ascending infection being excluded, these bacteria had in all probability entered ...1977339331
[bacteriological studies of the human amniotic fluid in repeated amniocenteses].the amniocentesis to gain increasing importance ought to be examined whether an alteration of the bacterial flora of the amniotic fluid was caused by repeated amniocentesis. 128 samples of amniotic fluid selected by abdominal amniocentesis were placed in microbiological cultures. bacteria was isolated in 30 cases, originated predominantly by pollution. under the circumstance of strong sterile conditions the amniocentesis proven even when repeated a diagnostical way of procedure which does not re ...1977339605
[urinary and serum o-antibodies in patients with chronic pyelonephritis (author's transl)].urine (24-hour-specimen, 100-fold concentrated) and serum samples from adults with chronic pyelonephritis have been investigated for o antibody against the strain isolated from the urine by means of the indirect hemagglutination and indirect immunofluorescence technique. using the hemagglutination technique about one third of the urine showed the presence of o antibody. the highest titer demonstrated was 1:16. o antibody determined by the immunofluorescence technique could be demonstrated in 54. ...1977339606
[transmission of the r-plasmids and expression of their genes in proteus mirabilis].resistance markers to individual antibiotics are transmitted in e. coli with the same frequency in the shape of a uniform linkage group, and in proteus mirabilis--with a different one. possibly in proteus mirabilis plasmide r6 dissociated, this being expressed in a different incidence of transconjugates, characterized by a different set of antibiotic resistance genes. tetracyclin resistance gene can be transmitted in p. mirabilis without being bound with other resistance determinants and with th ...1977339619
qualitative study of paradoxical zone phenomenon of penicillins against 17 bacterial species of clinical importance.using a triple agar layer technique and enzymatic inactivation of penicillin, the occurrence of a paradoxical zone phenomenon (illustrated by a typical 'target' image around the reservoir of antibiotic) was determined for several bacterial species specially chosen with regards to their taxonomic position, clinical importance and penicillin susceptibility. among gram-positive bacteria, a paradoxical zone was obtained for approximately 43% of the strains studied here (all 10 strains of staphylococ ...1978340171
correlation of minimum inhibitory concentration and beta-lactamase activity.the beta-lactamase activity of 510 recently isolated enterobacteriaceae was investigated with a quantitative photometric test. beta-lactamase could be detected in 55 percent of the enterobacteriaceae. at the same time minimal inhibition concentration (mic) of beta-lactam antibiotics was determined. there was no correlation between mic values and lactamase activity. for correct antibacterial therapy the clinician requires information on the lactamase activity of isolated bacteria in addition to t ...1977340386
