RESISTENSI KUMAN BORDETELLA PERTUSSIS TERHADAP ANTIBIOTIKA

The antibiotic resistancy of Bordetella pertussis to erythromicin, chloramphenicol and tetracyclin has been examined using Disc diffusion method described by Kirby bauer (1966) on Charcoal agar contains 10% sheep blood. The examination was done on positive culture which had been collected from 233 nasopharyngeal swab specimens. The results showed that no resistant to erythromicin (0%). Mean while there was significant resistancy to chloramphenicol (5,6%) and tetracyclin (25%). Antibiotic treatment should be given rationally to gain efficiency in antibiotic usage, to avoid antibiotic resistancy and to minimize cost of treatment.
