What is Prevalence of Porphyromonas gingivalis fimA genotypes in Caucasians about?

The aim of the present study was to determine the prevalence of __Porphyromonas gingivalis fimA__ genotypes in Caucasian patients with periodontitis. Atotal of 102 patients harboring __P. gingivalis__ subgingivally were enrolled into the study. Pooled subgingival plaque samples of the six most severely affected sites were taken and analysed by __fimA__‐specific polymerase chain reaction (PCR) and restriction analysis. Moreover, 26 __P. gingivalis__ isolates were analysed by sequence analysis of the __fimA__ gene. Sequence analysis revealed five major __fimA__ genotypes (__fimA__ types I–V) and allowed further subtyping of __fimA__ genotypes II and IV into two subgroups each. The overall prevalences of __fimA__ genotypes as assessed by PCR and restriction analysis among the __P. gingivalis__‐positive patients with periodontitis were: type I, 25.5%; type II, 38.2%; type III, 4.9%; type IV, 18.6%; type V, 3.9%; and non‐typable, 6.9%. Two patients were colonized by both type II and type IV, or type III and type IV __fimA__ genotypes, respectively. Patients harboring different __fimA__ genotypes showed no significant difference in severity of periodontal disease, as assessed by pocket p
