【文章內(nèi)容簡介】 ferentiation of bacteria principally relies: on microbial morphology and growth variables on culturing the organisms on nonselective and selective media. Culture remains the standard for diagnosis of bacterial infection because it is the simplest,the most reliable and the most cost efficient method. Another advantage is the fact that parallel testing of the sensitivity towards antibiotics is possible.,19,第十九頁，共三十頁。,n molecularbiological technics that provide rapid identification of infectious agents,both from culture isolates and directly within clinical specimens. on the detection of the antibody response to the pathogen. The concentration of infectionsepcific antibodies is determined in titers or activity units.,20,第二十頁，共三十頁。,In principle,the pathogen should be identified by culture in any acute infection that requires treatment.This,however,is only possible if the pathogen is still detectable in excretions,secretions,blood or tissue at the time when the clinical symptoms occur,e.g. salmonellae in feces in the case of diarrhea or gonococci from endocervical canal in genital tract infection.,21,第二十一頁，共三十頁。,病毒感染檢查
