近年细菌感染的研究已从对外源性感染发展到对以弱毒力的厌氧菌为主的内源性感染,即所谓“厌氧菌感染病”(AnaerobicInfectious Disease)因各种抗菌素、ACTH、抗癌药和放射治疗的广泛采用,使人体内常居菌丛发生紊乱,宿主对感染的抵抗力减弱而使厌氧菌感染较前增多;同时随着厌氧菌培养技术的快速发展使人们对感染的菌丛有了进一步的认识,关于这方面在医学各领域中均有报导,在口腔领域也是如此。如Olson(1975)指出以前认为人的口腔直接与
In recent years, the study of bacterial infection has progressed from exogenous infection to the endogenous infection mainly of anaerobic bacteria with weak virulence, so-called “Anaerobic Infectious Disease” due to various antibiotics, ACTH, anti Widely used cancer drugs and radiation therapy, so that the body of the resident flora disorder, the host resistance to infection weakened the anaerobic infections increased compared with the previous; at the same time with the rapid development of anaerobic culture technology so that people on the Infected flora has been further recognized, in this regard have been reported in all areas of medicine, in oral areas as well. As Olson (1975) points out, people previously thought that oral and direct
