decrease in ribosomal density of proteus mirabilis exposed to subinhibitory concentrations of ampicillin or cephalothin.the finding of reduced ribosomal densities at lower concentrations than those required to stop growth or cause visible defects in the cell wall is in contrast to the current view that the initial lesion produced by penicillins or cephalosporins is a defect in murein synthesis (11). this reduction in ribosomal density could be a primary or secondary effect and might be due to a decreased rate of growth, which has been shown to be associated with a lower ribosome frequency (12, 13) or to less stab ...19751096166
[phagocytosis of cell wall defective bacteria by human macrophages (author's transl)].statistically significant better phagocytosis of spheroplasts was found by comparing the rate of phagocytosis of normal and penicillin-g induced cell wall defective bacterial (spheroplasts) by human macrophages in isotonic media using a proteus mirabilis strain as test organism. this provides additional information concerning the minor role of cell wall defective bacteria as persisters in chronic infections.19751095903

transition of the r factor nr1 and proteus mirabilis: level of drug resistance of nontransitioned and transitioned cells.when proteus mirabilis harboring the r factor nr1 is cultured in penassay broth containing 100 mug of chloramphenicol (cm) per ml, there is an amplification in the number of copies of the r-determinants per cell. under these conditions, r factors harboring multiple tandem sequences of r-determinants are formed. autonomous poly-f-determinants consisting of multiple copies of r-determinants are also formed. this phenomenon has been referred to as the "transition". transitioned cells have considera ...19751095563
variation in expression of sex factor genes in the proteus-providencia group relative to escherichia coli.several instances of anomalous expression of genes introduced from escherichia coli k-12 into proteus mirabilis have been described. it is shown here that control of sex pilus synthesis directed by the f-like r factor r1 and its depressed derivatives r1-16 (o-c) and r1-19 (i-minus) is also anomalous in p. mirabilis. piliation in cells bearing the depressed plasmids is expressed at a lower level than in e. coli k-12, and repression is absent in r1-carrying cells. preliminary results show a simila ...19751095557
[cephalosporin antibiotics from microbiologic viewpoint. a comparison of antibacterial and pharmacokinetic properties].with the necessity not only of differentiating between effectiveness and non-effectiveness, as in the earlier phases of chemotherapy, but also of detecting graduated differences in effect quantitatively, animal experiment and clinical trial have been shown to be no longer adequate. in a correlating comparison of antibacterial activity with the drug level in vivo as the two decisive basic elements of chemotherapeutic effect, new and interesting possibilities arise for the evaluation of antibiotic ...19751095503
aminopenicillins - clinical pharmacology and use in disease states.ampicillin introduced in 1961 has been administered in the treatment of diverse infections by both oral and parenteral means. oral infections of the upper airways such as otitis media, bronchitis, and pneumonia have responded with high success rates since the microorganisms involved have remained sensitive to ampicillin. similarly, out-patient urinary tract infections caused by escherichia coli, proteus mirabilis, and enterococci are cured. typhoid fever may yet be treated with ampicillin, but s ...19751095502
[aminopenicillins from microbiological viewpoint].in this report it was tried to emphasize several microbiological aspects of the amino-penicillin. hereby it turns out that the activity differences of all the substances are very similar on microbiological part. a break of the cross-resistance does not happen with all the amino-penicillins. with regard to the appearance of resistant strains, it can be told that the conditions still are advantageous on non-hospitalized patients in the totality. in the clinic a high part of resistant strains are f ...19751095501
