The influence of coaggregation for a volatile sulfide production of Fusobacterium

本研究的目的是阐明具核梭杆菌与其他微生物的共聚集对F.核质F.结果表明，与F. gingivalis孵育相比，用活的牙龈卟啉单胞菌孵育可显著提高VSC的产量。只有核质。同时观察到F.与活牙龈卟啉单胞菌一起孵育时，与VSC产生相关的核质酶有增强的趋势，而与热灭活微生物或牙龈卟啉单胞菌培养基上清液孵育时则无影响。

The aim of this study was to clarify the influence of coaggregation between Fusobacterium nucleatum, a periodont pathogenic bacteria, and other microorganisms for production of volatile sulfur compound (VSC) by F. nucleatum. The coaggregation reaction was observed between F. nucleatum and Porphyromonas gingivalis, and shown that the production of VSC was significantly enhanced by incubation with live P. gingivalis compared to incubation F. nucleatum solely. It was also observed that the gene expression of F. nucleatum enzyme related with VSC production was tended to be enhanced by incubation with live P.gingivalis together whereas no effect was shown when incubated with heat-killed microorganism or supernatant of medium of P.gingivalis.
