PLASMID MEDIATED METAL AND ANTIBIOTIC RESISTANCE IN PSEUDOMONAS AERUGINOSA STRAINS ISOLATED FROM BURN PATIENTS

Pseudomonas aeruginosa is a leading cause of bum infections, and antibiotic- resistant strains of this bacterium are emerging due to extensive application of antibiotics in the bum unit of hospitals. In this study 50 strains of P. aeruginosa were isolated from bum patients infected with this micro-organism in the bum unit of a general hospital in Kerman, Iran over one year [May 1999-ApriI20...

Sensitivity testing of ciprofloxacin for Pseudomonas aeruginosa.

UK clinical laboratories overestimate ciprofloxacin resistance amongst Pseudomonas aeruginosa isolates, relative to the MIC breakpoint of 1 mg/L. Most tests leading to this overestimation use 1 microg discs and are by Stokes' method with the breakpoint taken as the zone radius for P. aeruginosa NCTC 10662 minus 3 mm. Aiming to reduce this error rate, we examined alternative disc breakpoints. Te...

Standardized chemical synthesis of Pseudomonas aeruginosa pyocyanin

Preparation of the toxin pyocyanin from the bacterium Pseudomonas aeruginosa is an exacting procedure. Pyocyanin is expensive to commercially purchase. The sellers do not give out the extraction procedure. Classically, pyocyanin preparation involves complicated multi-step P. aeruginosa culturing and solvent transfer extractions. The chemical synthesis first used (1979) has not been adequately d...

Use of ureidopenicillins for selection of plasmid vector transformants in Pseudomonas aeruginosa and Pseudomonas putida.

Broad-host-range plasmids coding for beta-lactamase were successfully selected after transformation of Pseudomonas strains. Transformants of both Pseudomonas aeruginosa and Pseudomonas putida containing plasmid pRO1614 were isolated in media containing low concentrations of piperacillin. These strains were also susceptible to other ureidopenicillins. Similar selections of transformants with car...

Alginate Polymerization and Modification Are Linked in Pseudomonas aeruginosa

UNLABELLED The molecular mechanisms of alginate polymerization/modification/secretion by a proposed envelope-spanning multiprotein complex are unknown. Here, bacterial two-hybrid assays and pulldown experiments showed that the catalytic subunit Alg8 directly interacts with the proposed copolymerase Alg44 while embedded in the cytoplasmic membrane. Alg44 additionally interacts with the lipoprote...
