Abstract

Nosocomial infection is an acquired infection in hospital that happened after 72 hours treatment at patient and beginafter a longer period than its incubation period. Most of the bacteria that causing nosocomial infection are moreresistant to antibiotics than community acquired bacteria. The purpose of this research was to find out the bacterialpattern and antibiotic susceptibility pattern which are used commonly at 2nd (second) surgery operating room in ArifinAchmad General Hospital. A laboratoric descriptive research had been done by swab, bacterial isolation in blood agarand endo agar, bacterial identification by macroscopic, microscopic and biochemical reaction method. The antibioticsusceptibility was using the Kirby-Bauer method. The result of this research showed that the most common isolatedorganism was Gram-positive (82.35%), those bacterias were Staphylococcus saprophyticus (29.41%), Bacillus sp.(23.53%), MRSA (17.65%), Staphylococcus aureus (5.88%), Staphylococcus epidermidis (5.88%). Followed by Gramnegative(17.65%), those bacterias were Pseudomonas aeruginosa (11.77%), and Enterobacter sp. (5.88%). This researchalso gave result antibiotics which have the high susceptibility were meropenem (76.9%) followed by ceftriaxone (38.5%)to bacteria that possibility causing nosocomial infection at 2nd (second) surgery operating room in Arifin AchmadGeneral Hospital.
