Proteomic analysis of keratitis-associated Pseudomonas aeruginosa
PURPOSE To compare the proteomic profile of a clinical isolate of Pseudomonas aeruginosa (P. aeruginosa) obtained from an infected cornea of a contact lens wearer and the laboratory strain P. aeruginosa ATCC 10145. METHODS Antibiotic sensitivity, motility, biofilm formation, and virulence tests were performed using standard methods. Whole protein lysates were analyzed with liquid chromatograp...
متن کاملPseudomonas aeruginosa infections associated with use of contaminated medicaments.
Pseudomonas aeruginosa was recovered from three hospital-prepared medicaments being used on the wards. Sixty-six patients were studied to observe the effect of using these contaminated medicaments. Psaeruginosa was recovered from 29 patients; in five the strains recovered bore a close resemblance to strains previously isolated from the contaminated medicaments.
متن کاملTLR4 is required for host resistance in Pseudomonas aeruginosa keratitis.
PURPOSE To determine the role of Toll-like receptor 4 (TLR4) in Pseudomonas aeruginosa (P. aeruginosa) keratitis in resistant (cornea-healing) BALB/c mice. METHODS Corneal TLR4 mRNA levels were tested by real-time PCR in BALB/c mice before and after infection. Clinical score, slit lamp, histopathology, bacterial counts, and polymorphonuclear neutrophil (PMN) quantitation were performed in the...
متن کاملEXTRACELLULAR LIPA SE ACTIVITY CHARACTERIZATION OF SOME PSEUDOMONAS AERUGINOSA STRA INS ISOLATED FROM HUMAN INFECTIONS
Pseudomonas aeruginosa EF2, ATCC 9027 and ATCC 19660 were grown in a continuous culture under Tween 80 (polyoxyethylene sorbitan monooleate) limitation and optimum conditions (pH 6.5, 37°C at dilution rate of 0.05/h). Culture supernatants were carefully removed and stored at -20°C. To purify the lipases, the culture supernatant was reduced in volume to approximately 10 mL by an ultrafiltra...
متن کاملCloning, Expression and Characterization of Recombinant Exotoxin A-Flagellin Fusion Protein as a New Vaccine Candidate against Pseudomonas aeruginosa Infections
Background: Infections due to Pseudomonas aeruginosa are among the leading causes of morbidity and mortality in patients who suffer from impaired immune responses and chronic diseases such as cystic fibrosis. At present, aggressive antibiotic therapy is the only choice for management of P. aeruginosa infections, but emergence of highly resistant strains necessitated the development of novel alt...
