Sensitivity of Actionbacillus Actinomycetemcomitans to Antibiotics and Effect of Sugar Addtion on Growth of the Bacteria

The purpose of the study was to identìfy the characteristics of the pathogenic microorganism Actinobacillus actinomycetemcomitans. The experìments of thìs study consìst of the decisìon 01 exìstence or nonexìstence of Actinobacillus actino~cetemcomitans ìn the aìr of dental clìnìcs, the effect of sugar on the growth of Actinobacillus actinomycetemcomitans, and lhe sensìtìvìty of Actinobaci/lus actinomycetemcomitans to Fluorine and antibìotìcs. The results of the experiments are as follows 1. Actinohacillω actino~cetemcomitans dìd not exist in the air of 4 dental clinics in Seoul 2. The growth of Actinobacillus actin뼈Y“temcomitans ìn the media containing glucose or sucrose was faster than ìn the media without these, and glucose was more effective than sucrose. 3. Actinobacillus actinomycetemcomitans was not susceptible to Fluorine at concentration between 0 ppm and 300 ppm. 4. Order of sensitivity of Actinobacillus actinomycetemcomitans to antobiotics was as follows:Tetracycline > Kanamycin > Ampicillin.
