Antibiotic Susceptibility of Pseudomonas Aeruginosa Isolated from Cystic Fibrosis Patients
Abstract Background and Objective: Cystic fibrosis (CF) is an autosomal recessive genetic disease and Pseudomonas aeruginosa is one of the most common bacteria colonized in CF patients. Growing resistance of this bacterium to antibiotics now a day is a challenge of controlling infection in CF patient. In this study colonization of CF patients with Pseudomonas aeruginosa and antibiotic suscep...
متن کاملFitness Landscape of Antibiotic Tolerance in Pseudomonas aeruginosa Biofilms
Bacteria in biofilms have higher antibiotic tolerance than their planktonic counterparts. A major outstanding question is the degree to which the biofilm-specific cellular state and its constituent genetic determinants contribute to this hyper-tolerant phenotype. Here, we used genome-wide functional profiling of a complex, heterogeneous mutant population of Pseudomonas aeruginosa MPAO1 in biofi...
متن کامل[Antibiotic susceptibility of Pseudomonas aeruginosa].
The susceptibility of 128 clinical isolates of Pseudomonas aeruginosa against amikacin, kanamycin, gentamycin, minocycline, colistin, chloramphenicol, claforan , piperacillin and carbenicillin were tested. Piperacillin, carbenicillin, amikacin and claforan are effective against at least 54% of strains tested. The susceptibilities of microorganisms to antibiotics were evaluated in different poin...
متن کاملAntibiotic resistance profiles of Pseudomonas aeruginosa isolates containing virulence genes
Background: A most common opportunistic pathogen, Pseudomonas aeruginosa is present in both humans and animals and responsible for various nosocomial infections and healthcare settings related infections. Different virulence genes like; oprL (membrane lipoprotein L) and toxA (exotoxin A i.e. ETA) in P. aeruginosa, assist in its pathogenicity, toxicity and contribute to high antibiotic resistanc...
متن کاملMechanisms of antibiotic resistance in Pseudomonas aeruginosa.
Pseudomonas aeruginosa is a notoriously difficult organism to control with antibiotics or disinfectants1. Recent reports on the antibiotic sensitivity patterns of P. aeruginosa in the UK have highlighted the problem of antibiotic resistance in cystic fibrosis (CF) strains in comparison with other hospital isolates2,3. Table 1 summarizes the current position in which the resistance rates of P. a...
