| transcription of escherichia coli ribosomal dna in proteus mirabilis. | transcription of escherichia coli ribosomal dna introduced into proteus mirabilis on f14 is described. we have developed an assay for e. coli coded ribosomal rna involving fingerprinting of ribonuclease t1 digests of rna isolated from ribosomal subunits. sequence differences in the ribosomal rna of the two species have allowed us to detect e. coli coded 16s, 23s, and 5s ribosomal rna in ribosomal subunits of the e. coli-p. mirabilis hybrid. the proportion of e. coli coded rrna in the hybrid is f ... | 1976 | 787756 |
| properties of plasmids constructed by the in vitro insertion of dna from rhizobium leguminosarum or proteus mirabilis into rp4. | plasmids have been constructed by insertion of dna from rhizobium leguminosarum or proteus mirabilis into rp4 (an r factor of group p). such recombinant plasmids retain the wide host range of the parental plasmid, being as efficiently transmissible as the unmodified rp4 and are stably maintained in rapidly growing cultures. the recombinant plasmids, even though each contained a dna sequence absolutely identical with that of the host strain, are no more efficient at mobilizing the transfer of chr ... | 1976 | 787766 |
| sensitivity patterns of urinary pathogens in the southland community and a study of sewage flora. | the overall sensitivity pattern of the three main urinary pathogens to the commonly used oral antibodies exceeded 80 percent. the incidence of multiple resistant escherichia coli was 8 percent. the resistant patterns of the sewage e. coli resembled that of the resistant urinary e. coli. however only one-third of the resistant urinary e. coli showed multiple resistance whereas two-thirds of the resistant e. coli in the sewage showed this feature. the resistance transfer was low in organisms isola ... | 1976 | 787846 |

| long-term study of humoral immune response in patients with chronic pyelonephritis. | indirect immunofluorescence was used for the measurement of serum antibody titers against the hemologous urinary strain of infecting organism in patients with a clinical diagnosis of chronic pyelonephritis. the passive hemagglutination technique was employed for comparison. the antibody response of the patients was followed-up for a period of two to four years. in contrast to titers determined by hemagglutination, antibody titers determined by immunofluorescence were found to be persistently ele ... | 1976 | 788977 |
| [bacteriological studies in outpatients with acute urinary tract infections with particular reference to the resistance spectrum (author's transl)]. | bacteriological investigation of urinary samples from 1,926 non-hospitalised patients with documented or suspected acute urinary tract infection revealed organisms pathogenic for the urinary tract in 56.4% of the patients, who came from various parts of west germany. prevalent pathogens were e. coli (69%) and proteus mirabilis (14%). e. coli and p. mirabilis demonstrated a low rate of resistance against ampicillin, the cephalosporines, gentamicin, tobramycin, and also against nitrofurantoin, nal ... | 1976 | 789245 |
| [antimicrobial effectiveness of sisomicin. i: in vitro activity of sisomicin compared with gentamicin, tobramycin, amikacin and kanamycin (author's transl)]. | the aminoglycosides sisomicin, gentamicin, tobramycin, amikacin and kanamycin are highly active against staphylococci including the penicillinase-positive strains. sisomicin is more effective than amikacin and kanamycin. mixed infections with staphylococci and enterobacteriaceae or pseudomonas aeruginosa are thus on indication for treatment with sisomicin or other aminoglycosides. infections with e. coli, enterobacter, susceptible klebsiella, and susceptible pseudomonas strains can be treated wi ... | 1976 | 789246 |
| [the liver concentration of cephradin and cephacetril and their elimination in the bile]. | liver biopsies and serum samples were collected after intravenous application of 2 g cephradin (n = 13) or 2 g cephacetril (n = 11) during surgery. there was no difference in the serum levels of cephradin and cephacetril. 30 min. after i.v. application of cephradin the liver tissue concentration was 72.62 mcg/g. 30 min. after i.v. cephacetril the liver tissue concentration was 5.83 mcg/g. the quotient of liver tissue concentration to serum concentration for cephradin was between 0.36 and 0.83, a ... | 1976 | 789253 |
| variation in urease activity of endemic hospital strains of proteus rettgeri and providencia stuartii. | both urease-positive and urease-negative proteeae isolated from cross-infected patients in the same hospitals and, in three cases, from the same patients were examined for their biochemical reactions and somatic (o-) antigens. all isolates gave the same reactions in 17 biochemical tests and possessed o-antigens characteristic of providenic o-type strains 4 or 17. study of the isolates indicated that endemic strains are capable of undergoing variation in urease activity. in the current classifica ... | 1976 | 789790 |

| human oral defenses against gram-negative rods. | gram-negative rods are unusual pharyngeal isolates in normal man, which suggests the presence of effective oral defense mechanisms against these organisms. to understand this protection better, we studied the elimination of gram-negative rods from the mouth after gargle challenge. suspensions of escherichia coli, klebsiella pneumoniae, and proteus mirabilis (108 organisms per ml) were gargled by normal volunteers, and pharyngeal swabs for serial quantitative cultures were taken for 3 hours. init ... | 1976 | 791034 |
| genetic relatedness in the family enterobacteriaceae. | five criteria of genetic relatedness are considered. the first, transfer of plasmids between groups, is frequently not a good criterion, because transfer is possible between all genera of the enterobacteriaceae and also to genera in other families. though transfer to closely related groups is most frequent, host restriction and the properties of the plasmid may influence the transfer frequency as much as the relatedness of the donor and recipient. the second criterion is interspecies recombinati ... | 1976 | 791071 |
| susceptibility of acinetobacter calcoaceticus var. anitratus (herellea vaginicola) to minocycline. | the in vitro activity of minocycline against acinetobacter calcoaceticus var. anitratus (herellea vaginicola) was examined. all strains of a. anitratus were inhibited by minocycline at concentrations of 0.4 mug/ml or less. the strains studied were considerably more susceptible to minocycline than tetracycline. no difference between the susceptibility to minocycline and tetracycline was seen with escherichia coli, klebsiella pneumoniae, enterobacter and proteus sp. a regression line of the log mi ... | 1976 | 791084 |
