微生物致病作用的研究,有很重要的理论和实际意义,是医学微生物学领域中重要的研究课题。近年来,这方面的研究有所进展,现仅就以下几个问题作一介绍。一、微生物通过粘膜侵入机体的机理(一)微生物通过粘膜的方式微生物通过呼吸道和消化道侵入机体是常见的两大感染途径。动物实验证明,不仅属肠道感染的微生物经肠道感染引起疾病,而且,非肠道感染的微生物,如狂犬病毒, Microbial pathogenic role of research, there is a very important theoretical and practical significance, is an important research topic in the field of medical microbiology. In recent years, research in this area has made some progress. Now we will introduce only the following issues. First, the mechanism of microbial invasion into the body through the mucosa (a) the way microorganisms through the mucosa Microorganisms invade the body through the respiratory and gastrointestinal tract is a common two major routes of infection. Animal experiments show that not only intestinal infections of microorganisms caused by intestinal infections, and, non-intestinal infections of microorganisms, such as rabies virus,
