口腔里的细菌数量很多,种类相当繁杂,有致病菌,也有非致病菌,还有条件致病菌。所谓条件致病菌就是在一定特殊条件下,这些菌对人就有致病作用了。 有人经实验推算出在正常健康人的每一克牙垢(牙锈)中可以找出100亿个细菌来。在每一毫升的普通唾液里可以寻找出奈瑟氏菌8000万个。在每一克牙龈分泌物中可以寻找出厌氧链球菌10亿个。 在口腔里细菌的种类繁杂,有葡萄球菌、链球菌、涎链球菌、轻性链球菌、厌氧链球菌、奈瑟氏菌、范永氏球菌、棒状杆菌、放线菌属、以色列放线菌、乳杆菌属、干酪乳杆菌、嗜酸乳杆菌、酶乳杆菌、短乳杆菌、双叉乳杆菌、厌氧扩菌属、匍行性菌属、梭菌属、泊氏奋森氏梭形杆菌、痰螺旋菌、痰弧菌属、色柔氏螺旋体等等。当然,最多、最主要的是链球菌、葡萄球菌和乳酸杆菌。 口腔中细菌种类的变化与人的生活习惯有关系,比如吸烟人的口腔中有烟草杆菌;口腔卫生不好的人,多厌氧菌。
The number of bacteria in the mouth a lot, very complex types, pathogens, but also non-pathogenic bacteria, as well as opportunistic pathogens. The so-called conditions of pathogenic bacteria is in certain special conditions, these bacteria have a pathogenic effect on people. Someone has experimentally figured out 10 billion bacteria can be found in every gram of tartar (tooth rust) in a healthy, healthy person. In each milliliter of ordinary saliva can find Neisseria 80 million. One gram of anaerobic streptococcus can be found in every gram of gingival secretions. Bacteria in the mouth of the complex species, Staphylococcus aureus, Streptococcus, Streptococcus salivarius, Streptococcus light, Streptococcus anaerobic, Neisseria, Pseudomonas, Corynebacterium, actinomycetes, Israel put line Lactobacillus, Lactobacillus casei, Lactobacillus acidophilus, Lactobacillus lactis, Lactobacillus brevis, Lactobacillus bifidum, Anaerobe difficile, Cephalic bacteria, Clostridium, Persea Fennensis Bacillus, sputum spirochetes, sputum Vibrio, Chromosome spirochetes and so on. Of course, the most, most notably, streptococci, staphylococci and lactobacilli. Changes in the type of bacteria in the mouth and the relationship between human life habits, such as tobacco in the mouth of tobacco bacteria; bad oral hygiene, and more anaerobic bacteria.
