Pseudomonas aeruginosa Infection and Antibiotic Sensitivity Pattern Isolated from a Tertiary Care Hospital in Dhaka City
Asian Journal of Research in Infectious Diseases,
Pseudomonas aeruginosa is one of the most widespread gram-negative microorganisms identified in the clinical samples and most common causes of hospital acquired infection. P. aeruginosa is affecting both indoor and outdoor patients throughout the world. Due to frequent mutation in P. aeruginosa highly resistant strain developed rapidly. The aim of the study to determine the prevalence of P. aeruginosa species in different samples isolated from a Tertiary care Hospital as well as determination their diverse antibiotic resistance pattern. This cross-sectional study was carried out to determine in-vitro resistance pattern of P. aeruginosa isolates to common antimicrobial agents by disc diffusion method. Various clinical samples were collected from Bangladesh Health Sciences Hospital (BIHS) General Hospital, Dhaka. This research was carried out in the Department of Microbiology of Bangladesh University of Health Sciences (BUHS). Isolation, identification and antibiogram were performed for P. aeruginosa following standard microbiological laboratory procedure. A total of 218 P. aeruginosa were isolated from 3062 different clinical specimens which are statistically significant (p<0.0001). Among the highest number of P. aeruginosa were isolated from outdoor patients 140 compare to Indoor patients which are significantly higher (p <0.013). In this study Male (68.3%) are more vulnerable to P. aeruginosa infection compare to females (31.7%) which is also statistically significant. Young people (less than 35 years) were more susceptible to P. aeruginosa infection which is also statistically significant (p< 0.01). The highest number of P. aeruginosa was isolated from wound (43.12%), followed by pus (40.33%), sputum (8.71%) urine (7.80%). The maximum number of P. aeruginosa in various samples was resistant to aztreonam and co-tromoxazole followed by cephalosporins, aminoglycosides, carbapenems. The most sensitive antibiotic was colistin of followed by gentamycin and tetracycline. To control the spread of resistant bacteria, it is disparagingly vital to have stringent antibiotic guidelines. The antibiotic susceptibility pattern of P. aeruginosa requires to be continuously monitored in specialized clinical units and the results readily made available to the clinicians to minimize the resistance.
