The sensitivity pattern of bacteria extracted from medical instruments of different wards of Kashani hospital to routine antibacterial agents, Shahrekord, 1996

Nosocomial infections are of particular concern to the medical and nursing professions. These infections are caused by pathogenic organisms that are transmitted to patients by hospital personnel, medical instruments, etc. This study was carried out in Shahrekord Kashani hospital to identify these pathogenic bacterial strains and also their sensitivity to some antibacterial agents. 140 swab samples were collected from nursing station tables, food dishes, staff hands, tracheal tubes and other parts of seven wards of the hospital and were cultured for the identification of pathogenic bacteria. Antibacterial sensitivity tests were also performed using povidone iodine 10%, ethylic alcohol 70% and cetrimide-C 1.3%. 28% of the collected samples were positive for pathogenic bacteria. 49 bacterial strains were isolated from the samples, from which Staphylococcus aureus was the most prevalent one. Besides, Esherchia colt, Staphylococcus epidermidis, Pseudomonas aeroginosa and klebciella species were isolated. Approximately all of the pseudomonas species were resistant to the most concentrations of antibacterial agents. However, povidone idodine 10% and cetrimide-C 3% had the best antibacterial effect on the gram (+) and gram (-) bacterial strains. Cetrimide-C was more effective on gram (+) strains. As a result, the control procedures and using the proper antibacterial agent in disinfection of hospital and medical instruments should be repeatedly notified to the medical staff.
