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
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
[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
[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
[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
an experimental study on the pathogenesis of sporadic bacteriuria in the rat.an 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
