Studies on multidrug resistant Pseudomonas aeruginosa from pediatric population with special reference to extended spectrum beta lactamase


A total of 53 isolates of Pseudomonas aeruginosa were obtained from 250 clinical samples from pediatric populations in Chennai. The isolates were obtained from clinical specimens viz. the throat swab, ear swab and urine sample. The isolates of P. aeruginosa were subjected to antibiotic sensitivity test. Among various antibiotics tested, the strains showed highest resistance to ampicillin (85%), followed by amikacin (62.2%), norfloxacin (60.3%) and ciprofloxacin (50.9%). The data on ESBL production indicated overall production of 25% among MDR strains. MIC values for the antibiotics ranged from 3.9 µg/ml to 256µg/ml. These data suggest that the prevalence of ESBLs which are very important as these strains may often cause outbreaks in the pediatric population and causes increased morbidity and mortality in patients underlying diseases or limit therapeutic options due to the high degree of multidrug resistance.
