The @entity2522 and @entity2521 are very common diseases in Hungary: more than 80% of the adult population suffers with @entity2522 and 15-20% has destructive @entity2521 . The composition of peridontopathogenic bacterial flora is totally different from that of the bacterial flora causing @entity281 . In periodontal @entity281 dominantly facultative and obligatory anaerobic microorganisms occur ( @entity3841 (A. actinomycetemcomitans), @entity2523 ( @entity2523 ), @entity3289 ( @entity3289 ). The main objective of the study was to investigate the microbial flora of the rapidly progressing @entity2521 with special respect to the occurrence of the Actinobacillus actinomycetemcomitans. The antibiotic susceptibility of the A. actinomycetemcomitans was also determined against the most frequently used conventional antibiotics. Twenty-five samples collected from @entity1 with rapidly progressing @entity2521 were examined. Prevalence and ratio of A. actinomycetemcomitans and other species of the periodontal anaerobic flora were investigated. MIC values of different antibiotics used routinely-- @entity3402 , @entity115 / @entity798 , @entity803 , @entity868 --were measured. Prevalence of black pigmented bacteroides (50%), and A. actinomycetemcomitans (30%) was comparable to data of foreign investigators. A. actinomycetemcomitans spp. appear to be more sensitive to @entity3402 and @entity115 / @entity798 and more resistant to @entity868 compared to published data. The knowledge of microbial composition of the periodontal flora could help to diagnose the different forms of @entity2521 . It can also assist the indication of the most appropriate antibiotic therapy.
