Prevalence and Resistance pattern of Pseudomonas strains isolated from ICU Patients

Antibiotic resistance is a major concern in contemporary medicine. The ongoing emergence of resistant strains that cause nosocomial infections contributes substantially to the morbidity and mortality of hospitalized patients (Acar JE et al., 1997, Goldmann DA et al., 1996). Bacteria from intensive care units (ICUs) have the highest proportion of resistance (Fridkin SK et al.,1999). Pseudomonas aeruginosa is one of the main organisms responsible for drug-resistant nosocomial infections. Aerobic, oxidase positive, non fermenter, Pseudomonas aeruginosa is becoming day by day a very common pathogen. It is being isolated from various clinical samples. It belongs to the genus Pseudomonas, which is widely distributed in nature. Although it is considered as a contaminant, it may colonize healthy humans without causing disease, but sometimes, it s potential to act as a pathogen can be identified without any doubt due to its isolation in clinical ISSN: 2319-7706 Volume 3 Number 3 (2014) pp. 527-534 http://www.ijcmas.com
