众所周知,胆道系统是带菌者慢性感染的病灶之一,如检查125人的胆汁,其中91人20～30年前罹患伤寒,胆汁培养16.4％分离出伤寒杆菌,另34人既往史无殊,胆汁培养仅5.8％分离出伤寒杆菌。同时对照粪便培养,前者仅8.7％分离出伤寒杆菌。因此,等认为在系统观察下胆汁培养的阳性率较粪便培养增高9倍(0.4和4.05％),当重复检查时阳性率提高,粪便为3.3％,胆汁为51％。Merselis等指出,在服用利胆药物后,通过
As we all know, the biliary system is one of the carriers of chronic infection of the lesion, such as checking the bile of 125 people, of which 91 20 to 30 years ago suffering from typhoid fever, bile culture 16.4% isolated Salmonella typhi, the other 34 people no previous history of special bile Culture only 5.8% isolated Salmonella typhi. At the same time control faecal culture, the former only 8.7% isolated Salmonella typhi. Therefore, it is considered that the positive rate of bile culture is 9 times (0.4 and 4.05%) higher than that of stool culture under systematic observation, and the positive rate is increased when repeated examination. The stool is 3.3% and the bile is 51%. Merselis and others pointed out that after taking gallbladder medication, through
