什么是定植抗力 Vanderwaaij给普通小鼠和无菌小鼠口服细菌,污染小鼠。给普通小鼠口服的细菌,是对链霉素和氨苄青霉素(Streptomycin and ampicillin)耐药的菌种。把这两种药投给小鼠。该普通小鼠肠道的正常菌群中,对于药物敏感的菌都被杀灭了。污染之后两周,仍然还处于污染的动物的百分数和口服细菌数量的自然对数之间,有高度的再现关系。在普通小鼠,对于大多数潜在致病菌,需要口服量很大,经过一定时间,才能在普通小 What is colonization resistance? Vanderwaaij orally inoculates bacteria into common and germ-free mice and contaminates mice. Bacteria that are orally administered to common mice are strains resistant to streptomycin and ampicillin. The two kinds of medicine for mice. In the normal flora of the normal mouse intestine, drug-sensitive bacteria are killed. Two weeks after the contamination, there was a high degree of reproductive relationship between the percentage of animals that were still contaminated and the natural log of oral bacterial counts. In ordinary mice, for most of the potential pathogens, need a large amount of oral, after a certain period of time, in the ordinary small
