Pseudomonas aeruginosa evaluation

Ayres H., Furr J.R. Russell A.D. (t993) A rapid method of evaluating permeabilizing activity against Pseudomonas aeruginosa. Lett Appl Microbiol, 11, i49-t87. 

Further to these results, the microbicidal activities of FIBCIDE-KF and KATHON WT were evaluated. The minimum inhibitory concentrations (MIC) for Pseudomonas aeruginosa, Pseudomonas putida, Bacillus subtilis and Microbacterium sp. are identical for both compounds, so the microbicidal effect has not diminished (Figure 10). It appears that the biocidal effects are similar because the Cl-MIT in the inclusion complex is released into water, as shown in Figure 6. 

Nablo et al. were the first to evaluate the antibacterial properties of NO-releasing xerogels using Pseudomonas aeruginosa and Staphylococcus aureus as... 

Rangel et al. [29] evaluated the antimicrobial activity of the aerial parts of Pseudognaphalium moritzianum (Klatt) Badillo. Ethanol and acetone extracts showed activity against Staphylococcus aureus. Enterococcus faecalis and Pseudomonas aeruginosa, while the aqueous extract was only active towards Staphylococcus aureus and Pseudomonas aeruginosa. 

The essential oil composition and antimicrobial activity of Osmitopsis asteriscoides (Berg) Less, a medicinal plant used in traditional preparations in South Africa has been investigated [125]. Three different antimicrobial methods were comparatively evaluated against Candida albicans. Staphylococcus aureus and Pseudomonas aeruginosa The two major essential oil components, camphor. Fig. (1) and 1,8-cineole, Fig. (2) were investigated, indieating the positive antimicrobial efficacy of 1,8-cineole, Fig. (2), independently and in combination with camphor, Fig. (1). 

A number of antibiotics have been used as aerosol therapies. Examples include beta lactam agents, polymycin antimicrobials, neomycin, gentamicin, and tobramycin. Many of the early efforts were reported as case studies, and observations and data regarding safety and efficacy were lacking. Controlled clinical trials were not conducted until the middle of the 1980s. More recent evaluations have focused on the role of inhaled tobramycin used as suppressive therapy for cystic fibrosis patients colonized with Pseudomonas aeruginosa. 

These findings prompted the development and evaluation of the currently available form of inhaled tobramycin, which is sterile and free of preservatives. The benefit of maintenance therapy with this inhaled tobramycin is supported by the results from two 24-week, multicenter, randomized, double blind, placebo-controlled clinical trials [6]. In these studies, patients with cystic fibrosis were at least six years of age, with an FEVj between 25% and 75% predicted. All subjects had evidence of colonization with Pseudomonas aeruginosa. Exclusion criteria included an elevated serum creatinine or colonization with Burkholderia cepacia, which is typically resistant to tobramycin. Subjects in the active treatment arm received inhaled tobramycin 300 mg twice daily through... 

EN 1040 Bacteria. The test germs are Pseudomonas aeruginosa and Staphylococcus aureus and the test conditions include a temperature of 20°C and contact times of 1, 5, 15, 30, 45, and 60 minutes. This test evaluates the basic efficacy of the product. 

We studied the antimicrobial properties [33] of three Fraxinus ornus bark extracts and their main components 1-4 against Staphylococcus aureus, Candida species, Escherichia coli and Pseudomonas aeruginosa using the procedure of Heiss [34]. Evaluation of microbial growth on the contact surface was performed by measuring the Contact Growth Index (CGI). The crude extract (extract A) of the bark was separated into... 

In vitro quantitative antibacterial activity was evaluated using Alamar Blue Assay [56]. It is a colorimetric oxidation-reduction assay which involves the addition of Alamar blue dye as an indicator. It evaluates the metabolic activity of the microorganisms. The activity of the evaluated drug is expressed as minimum inhibitory concentration ( 0,g/ml). Sampangine, SAMM2 and SAM MMl were tested for their activity against Staphylococcus aureus ATCC 6538, Pseudomonas aeruginosa ATCC 15442, Bacillus subtilus ATCC 6633, and E. coli ATCC 10536. Streptomycin was used as a positive control.
