| hyperbilirubinemia in infants with urinary tract infection. | in the light of a retrospective analysis of 213 case records of infants with urinary tract infections, hyperbilirubinemia was disclosed in 19 cases. in 7 cases jaundice was the main cause of admission of these children to the hospital. it was observed mainly in the youngest age group up to 3 months. jaundice was hemolytic in some cases and hepatic in others. urinary tract malformations had no effect on the frequency of jaundice in urinary tract infection or on its intensity. | 1976 | 792839 |

| the varying sensitivity to antibacterial agents of micro-organisms in pure vs. mixed cultures. | in this study the disc sensitivities of five organisms growing in pure cultures (staphylococcus aureus, beta-hemolytic streptococcus, proteus mirabilis, pseudomonas aeruginosa, and candida albicans) were first determined against each of seven antibacterial agents (penicillin, streptomycin, gentamicin, kanamycin, silver nitrate, sulfamylon, and betadine). then the sensitivity of each organism growing in combination with one of the others (10 combinations) was tested against each of the same antib ... | 1975 | 806983 |
| [significance of the antibacterial agent assay of urine for bacteriological diagnosis and control of chemotherapy of urinary tract infections (author's transl)]. | the disc agar-diffusion-test using bacillus subtilis atcc 6051 as test organism is a simple and rapid method for routine testing of antibacterial agents in urine specimens. the test records urine levels which are expected under medium dosage, and in many cases even lower concentrations of renal excreted antibiotics. out of 5655 analysed urine samples 22% contain antibacterial substances. in urine specimens over which information was volunteered that either no chemotherapy had been administered o ... | 1975 | 807057 |
| a critical look at chemical disinfection of anaesthetic apparatus. | studies were carried out to test the efficacy of disinfection of a previously contaminated corrugated anaesthetic tube and reservoir bag. bacteriological swabs and sampling with broth were evaluated as methods of detecting contamination. gross contamination was detected by broth sampling on occasions when swabbing failed to reveal contamination. the presence of up to 18% by volume of residual air within the apparatus was detected. a method of ensuring elimination of all air is described and stud ... | 1975 | 807229 |
| comparative activity of tobramycin and gentamicin against pseudomonas, proteus and providencia species. | tobramycin is a new antibiotic resembling gentamicin. we measured the minimal inhibitory concentrations of these two antibiotics against five bacterial species that cause hospital-acquired infections and are resistant to many presently available antibiotics. the organisms tested were 500 strains of pseudomones aeruginosa, 100 strains of each of proteus rettgeri and pr. morganii, 50 strains of pr. vulgaris and 250 strains of providencia stuartii. tobramycin was 2 to 4 times more active than genta ... | 1975 | 807310 |
| comparison of the in vitro activities of bb-k8 and three other aminoglycosides against 215 strains of pseudomonas and enterobacteriaceae with variable sensitivity to kanamycin and gentamicin. | 215 gram-negative bacilli isolated from clinical materials were tested in vitro against bb-k8 by means of disc diffusion and agar dilution tests; the strains included 40 isolates resistant to gentamicin. approximately 90% of the strains were inhibited by 3.12 mug/ml or less bb-k8. this antibiotic exhibited a comparable activity, although somewhat inferior, to that of gentamicin, against organisms sensitive to gentamicin. it was considrably more active than gentamicin, and comparable to tobramyci ... | 1975 | 807457 |
| systematic difference in the methylation of ribosomal ribonucleic acid from gram-positive and gram-negative bacteria. | a survey of gram-positive and gram-negative organisms was performed to compare the distributionof n6-methylated adenine. it was found that (i) all the gram-positive strains tested, staphylococcus aureus, sarcina lutea, bacillus stearothermophilus, bacillus subtilis, and bacillus megaterium, contain neither n6-monomethyl adenine (m6a) nor n6-dimethyladenine (m26a) in 23s ribosomal ribonucleic acid (rrna). in the case of s. aureus and streptococcus pyogenes, strains which are clinically resistant ... | 1975 | 807565 |
| detection of endotoxins with the limulus test in burned and unburned mice infected with different species of gram-negative bacteria. | the limulus test detected endotoxins in the plasma of burned and unburned mice infected with different species of gram-negative bacteria produced different amounts of endotoxin in the plasma of infected mice. plasma from mice given lethal infections showed very high concentrations of endotoxin. low concentrations of endotoxin in the plasma were tolerated by mice but high concentrations were invariably fatal. a polyvalent pseudomonas vaccine reduced endotoxin in the plasma of mice given lethal in ... | 1975 | 807621 |
| interference with alpha-antitrypsin studues in stored serum by presumed bacterial proteases. | contamination of werum by certain gram-negative bacteria has been shown to spoil the serum for measurement of trypsin inhibitory capacity (stic) or for antitrypsin phenotyping. such sera develop intense fibrinolytic activity when the stic has dropped to itsminimal level, but antitrypsin concentration as measured by radial immunodiffusion remainsconstant. cultures of enterobacter, klebsiella, bacillus subtilis, and pseudomonas species were shown to have this capability, but production of the fi ... | 1975 | 807660 |
| the use of analytical isoelectric focusing for detection and identification of beta-lactamases. | beta-lactamases (ec. 3.5.2.6) from strains of gram-negative bacteria have been studied using analytical isoelectric focusing. this permits a visual comparison of the patterns of beta-lactamase bands produced by enzymes from different organisms. purification of crude intracellular preparations is unnecessary and the technique is sufficiently sensitive to demonstrate beta-lactamase in mutants previously reported to lack the enzyme. r that have not been distinguished from one another biochemically ... | 1975 | 807678 |
| contractility of glycerinated amoeba proteus and chaos-chaos. | immediate contact with large volumes of cold 50% (v/v) buffered glycerol preserved typical ameboid shape of chaos chaos and amoeba proteus with no visible distortions. these technics allowed determination of the contraction sites in these glycerinated models upon applications of atp-ca-mg-solutions. the ectoplasmic tube was the main site of contraction. preliminary em investigations revealed thick and thin filaments, associated with the ectoplasmic tube near the plasma-lemma, which appeared to b ... | 1975 | 807722 |
