Clinical correlation of Pseudomonas aeruginosa isolated from clinical settings at Civil Hospital, Ahmedabad.

Introduction: Pseudomonas aeruginosa species can be dangerous opportunistic pathogen because of its tolerance to physical, chemical, antibacterial compounds. In hospitals, P. aeruginosa is a formidable opportunistic pathogen, and therefore, the medical concern with infection of immunologically compromised patients in burns and neonatal units, is well justified. Material and methods: Total 1583 samples like swab, urine, sputum, pus, pleural fluid, bronchoalveolar lavage (BAL), ascitic fluid and blood samples from different clinical departments were tested at Clinical Microbiology Department of B. J. Medical College and Civil Hospital, Ahmedabad, Gujarat during April 2009 to April 2010. Results: Out of 1583 samples, 807 samples turned culture positive. Out of 807 culture positive samples, 100 were culture positive for P. aeruginosa. The maximum number (68%) of P. aeruginosa isolates were obtained from swab samples. The highest number of such isolates (48%) belonged to surgical ward. P. aeruginosa showed highest sensitivity against Cefepime - Tazobactam (97%). Conclusion: This study showed that P. aeruginosa is acquiring resistance to commonly used antibiotics as well as newer antibiotics. The antimicrobial agents are losing their efficacy because of spread of the resistant organism, indiscriminate use of antibiotics, and unhygienic condition. It is the need of the time that antibiotic policies should be formulated and implemented to resist and overcome this serious problem.

In-vitro antibiotic sensitivity pattern of Salmonella typhi.

Introduction: Salmonella typhi is widely prevalent in India and it causes endemic and epidemic typhoid fever. Early and proper antibiotic administration is necessary to reduce morbidity, complication and mortality of typhoid. Material and methods: A total of 1006 febrile patients, receiving treatment at Guru Govindsingh Hospital, Jamnagar, were included in this study. 1006 blood culture samples for S.typhi Were collected from these patients. Blood cultures were tested for clinical bacteriology, as per standard protocol. Results: 30 blood cultures grew positive for S. typhi with the isolation rate of 2.98%. 60% S. typhi isolates were resitant to chlorampheenical, amppicillin, and co-trimoxazole and hence, were multidrug resistent S. typhi ciprofloxacin was the most effective drug with 93.33% senstivity. Conclusion: Ciprofloxacin remains the drug of choice for treatment of typhoid fever. Unchecked use of ciprofloxacin antibiotic should be rationalized, since selection pressure has now emerged as ciprofloxacin resistant in S. typhi.

Antibiotic sensitivity pattern of causative bacterial pathogens responsible for corneal ulcer.

Introduction: Number of blind people in the world is 45 million. Out of which 5.4 million blind people are in our country. Corneal ulcer is a major cause of blindness throughout the world. About10% cases of blindness are due to corneal ulcer. Aim:To detect antibiotic sensitivity Pattern of causative bacteria responsible for corneal ulcer. Material and mathod: 150 samples were collected during period of 1 year from clinically diagnosed cases of corneal ulcer at SSG Hospital, Baroda.Results: Total 150 samples were tested for antibiotic sensitivity pattern and among them Gram positive bacteria showed highest sensitivity to ciprofloxacin and among Gram negative bacteria showed highest sensitivity to ciprofloxacin, gatifloxacin and amikacin while pseudomonas showed highest sensitivity to imepenem.
