A new pyoverdin from Pseudomonas aeruginosa R'.
From a Pseudomonas aeruginosa hospital isolate a new pyoverdin was isolated. It is identical with that of Pseudomonas aeruginosa strain R except that in the peptide chain L-Gln is missing.
متن کاملR factor-mediated aminoglycoside antibiotic resistance in Pseudomonas aeruginosa: a new aminoglycoside 6'-N-acetyltransferase.
The newly introduced semisynthetic aminoglycoside antibiotics, i.e., 3',4'-dideoxykanamycin B (DKB), 6'-N-methyl DKB (6'-Me-DKB) and amikacin (AK) have been found to be effective against gram-negative pathogens including Pseudomonas aeruginosa, which are resistant to the known aminoglycoside antibiotics. We have demonstrated in our stock cultures two types of P. aeruginosa strains resistant to ...
متن کاملGentamicin resistance in Pseudomonas aeruginosa: R-factor-mediated resistance.
By disk diffusion antimicrobial susceptibility testing, 11% of 313 consecutive strains of Pseudomonas aeruginosa, examined during July to October 1973, were resistant to gentamicin (minimal inhibitory concentration 12.5 to >100 mug/ml), and a further 31% were moderately resistant (6.25 to 12.5 mug/ml) to gentamicin at the University of Alberta Hospital in Edmonton, Canada. Of 45 gentamicin-resi...
متن کاملCharacterization of Pseudomonas aeruginosa derepressed R-plasmids.
A genetic study of conjugal transmissibility of two R-plasmids was undertaken in Pseudomonas aeruginosa. Conjugally derepressed mutants of the R-plasmids were isolated, and examination of 11 independent mutants revealed that 10 were recessive to the wild-type transfer repressor, whereas 1 mutant was cis dominant. Cross-repression was observed between the two R-plasmids, suggesting that they hav...
متن کاملIsolation and characterization of lividomycin A inactivated by Pseudomonas aeruginosa and Escherichia coli carrying R factor.
served in IR spectrum. The inactivated lividomycin A consumed 6.2 moles of periodate for 24 hours as does lividomycin A (5.9 moles). Methanolysis of the inactivated lividomycin A (refluxed in 0.4 N hydrogen chloride in methanol for 6 hours) gave 3'deoxyparomamine, methyl lividotriosaminide phosphate and a small amount of methyl lividobiosaminide phosphate. These results indicate that the inacti...
