It has been reported that staphylococci present in clinic and personnel are transmissible to patients. The purpose of this study is to ascertain the distribution, the drug resistance and plasmid pattern in Micrococcaceae isolated in dental clinic. A dental clinic was monitored in the morning, in the afternoon and in the evening. S hemolyticus was isolated from the cover of instruments and S. hominis was isolated from the margin of tray in the morning. S.erpidermidis was isolated from light switch and head resd, S. aureus from cuspidor and head rest, and coagulase-negative staphylococci from suction tip in the afternoon. S. aures was isolated from head rest and coagulase-negative staphylococci was isolated from suction rubber tip in the evening. Micrococci were isolated from the forceps tip and the switch in the evening. Staphylorocci isolated in the afternoon showed susceptibility to ceftriaxone, and those isotated in the evening to ampicillin, carbenicillin, tetracyclin, gentamycin, amikacin, cephalothin, ceftriaxone and cefoxitin. Microcotcus isolated in the evening showed susceptibility to 15 antibiotics. In the analysis of plasmid, there were two clear bands about 4.3 kb, in S. aures isolated from the head rest in the afteraoon. These results show that Micrococcaceae can become ambient in dental clinic, and staphylococci isolated then show antibiotic resistance to some drugs.
