A study of antimicrobial sensitivity of Pseudomonas aeruginosa isolated from clinical sources from different diagnostic centers, Dhaka, Bangladesh was carried out to facilitate the preference of drug in the management of Pseudomonas aeruginosa induced symptoms. Very low sensitivity of P. aeruginosa towards co-trimoxazole (45%), azithromycin (30%) and erythromycin (35%) was observed. Higher sensitivity pattern was observed for cefuroxime (57.5%). and only imipenem (100%) has shown sensitivity pattern possibly susceptible enough to consider for the management of P. aeruginosa induced cases in the area under study. The low sensitivity to different antimicrobial could be attributed to their prevailing usage and abuse in the area under study.Keywords: Antimicrobial sensitivity; Clinical isolates; Pseudomonas aeruginosa.© 2011 JSR Publications.

Background: Antimicrobial sensitivity pattern from clinical isolates can reveal important information that can help in drafting the hospital antibiotic policy as well as help improve prescribing patterns and patient outcome in a particular region.Methods: Data from the results of the antimicrobial sensitivity pattern of clinical isolates of the patients between 1stJuly and 31st December 2018 were collected on a pre-designed and pre tested case study form and analysed with the help of descriptive statistics.Results: A total of 75 blood culture reports were obtained which showed 58 gram positive cultures. Further 46 of the gram positive samples were positive for Coagulase negative Staphylococcus. A total of 305 urine samples were obtained for culture which showed gram negative cultures. Paediatric and medicine wards were the common yielding sites. A total of 242 pus reports were obtained which showed 47 gram positive cultures. A total of 154 wound swab samples were obtained which showed 47 gram positive cultures. For pus and wound swab samples, surgery wards were the common yielding sites. Common gram negative organisms seen were Klebsiella sp., E. coli, Citrobacter sp., Pseudomonas, Proteus and Enterobacter. Gram positive organisms were commonly resistant to Erythromycin, orally active Penicillins, Vancomycin and Teicoplanin and gram negative organisms were commonly resistant to Cephalosporins, Aminoglycosides, Colistin, Fluroquinolones and Meropenem.Conclusions: This study showed that over six months samples of body pus, wound swab, blood culture and urine showed high levels of resistance to commonly used antibiotics. This would provide an outline for development of an effective hospital Infection Control Policy.

Sensitivity Pattern

A prospective study was carried out in 50 burn patients admitted in Burn unit of Dhaka Medical College Hospital over a period of one year from January 2005 to December 2005 to evaluate time-related changes in aerobic bacterial colonization and their sensitivity pattern. Periodic swabs were taken from the burn wound on Day 0, Day 7, Day 14 and Day 21 to see the changing pattern of organisms during hospital stay of patients. In the present study burn injury was highest in the age group 11-20 yrs (34%). Male to female ratio was 1.38:1. The mean percentage of burn was 35.79% of total body surface area (TBSA). Fire was the major cause of burn (38%) followed by electric burn (20%). Among the 200 samples, single organism was isolated in 71% samples and mixed organism in 13.5% and no growth in 14.5%. Among single isolates Pseudomonas aeruginosa was leading (28%) followed by Escherichia coli (17.5%), Staphylococcus aureus (16%), coagulse negative Staphylococcus (4.5%) and Klebsiella (2%). Among mixed growth Pseudomonas aeruginosa was still leading (11%) follow by E. coli (9.5%) Staphylococcus (5.5%), Proteus (1%) and Klebsiella (0.5%).There were time -related changes in bacterial isolation from burn wound during hospital stay of patients. On admission 42% of the isolated organisms were Staphylococcus aureus and only 6% each Pseudomonas aerunginosa and E. coli were isolated. No growth was found in 28%. samples. These findings were gradually changing with time and on day 21 Staphylococcus aureus were only 4% whereas Pseudomonas aeruginosa were 40% and E. coli 28%. Antimicrobial sensitivity test showed that pseudomonas aeruginosa was highly resistant to antimicrobial agents. It was most sensitive to Imipenem (98.72%) followed by Aztreonam (33.44%), Ceftazidime (38.32%) and Gentamicin (19.23%). E. coli was also found most sensitive to Imipenem (98.15%) followed by Gentamicin (38.95%), Chloramphenicol (37.1%), Ciprofloxacin (35.25%) and ceftraixone (29.70%). Staphylococcus aureus was 100% sensitive to Vancomycin followed by Amoxiclav and Oxacillin (53.43% each), Gentamicin (44.70%) and Cloxacillin (39.52%). It is crucial for every burn institution to determine the specific pattern of burn wound microbial colonization, the time-related changes in dominant flora, and the antimicrobial sensitivity profiles. This would enable early treatment of septic episodes with proper empirical systemic antibiotics without waiting for culture results, thus improving overall infection related morbidity and mortality.

Among gram-negative microorganisms Pseudomonas aeruginosa is the most common bacteria identified in different clinical specimens of hospitalized patients. A few studies have been conducted in Saudi Arabia regarding antibiotic susceptibility pattern. The purpose of this study was to evaluate the current levels of antibiotic susceptibility and to assess the resistance pattern of antibiotics among the clinical isolates of P. aeruginosa in the King Khalid Hospital, Alkharj, Kingdom of Saudi Arabia. This study was carried out during January, 2015 to May, 2015. A total of 180 different specimens such as sputum, urine, pus swabs, wound swabs etc. were collected from different patients admitted to the hospital. Thirty (30) clinical isolates of P. aeruginosa were isolated from different specimens of the patients suspected of having respiratory tract infection, urinary tract infection, wound infections, etc. The antibiotic susceptibility profiles of all the isolates were determined using Kirby-Bauer disk diffusion method. Piperacillin-tazobactam was found to be the most active antimicrobial agent with 96.7% susceptibility followed by cefepime (83.3%), ceftazidime (83.3%), and ciprofloxacin (76.7%). All isolates were resistant to ertapenem, cefuroxime, cefoxitin and nitrofurantoin. Anti-bacterial treatment strategies should focus on P. aeruginosa, for which the prevalence rates are increasing every year. The usage of piperacillin-tazobactam, cefepime, ceftazidime and ciprofloxacin must be reserved and only be given to the patients after susceptibility test to reduce the resistance of P. aeruginosa against these agents.

Introduction: Pseudomonas aeruginosa (P. aeruginosa) is one of the major cause of nosocomial infection. Multi-drug-resistant P. aeruginosa (MDR PA) are increasingly encountered in clinical samples .Therefore, this study was undertaken to know the sensitivity pattern of P. aeruginosa and to detect MDR PA from clinical samples. Methods: This was a laboratory based retrospective-cross sectional study conducted at Department of Microbiology at a tertiary care referral centre in Kathmandu, Nepal from December 2018 to December 2019. Total of 200 isolates of P. aeruginosa were isolated from clinical samples. Non repetitive sample per patient was included in the study. Samples were processed according to standard methodology and antimicrobial sensitivity testing (AMST) was carried out by Modified Kirby Bauer disk diffusion test as per Clinical Laboratory Standard Institute guideline. MDR was defined as strains resistant to one or more agent of ≥ 3 groups of antimicrobial categories. Results: Highest number of P. aeruginosa were isolated from sputum (93), followed by wound swab (35), and pus (29). AMST revealed the most sensitive drug to be Amikacin (91.51%) followed by Meropenem (78.5%) and Piperacillin/Tazobactam (77.50%). Out of 200 isolates, 69 (34.5%) were MDRPA. Conclusions: The information regarding sensitivity pattern of P. aeruginosa will help clinicians to choose most effective antimicrobials for the treatment of patients thus saving the time duration and total cost of patient management and also it will play a key role in setting antimicrobial stewardship policy.
