In a prospective comparative study, 2,696 consecutive fresh stool specimens over the course of 1 year were examined for Giardia lamblia and Cryptosporidium parvum by using a direct immunofluorescent-monoclonal antibody stain (for unspun specimens) and conventional staining methods (chlorazol black E for Giardia cysts and modified Kinyoun acid-fast for Cryptosporidium oocysts). The direct immunofluorescent-monoclonal antibody method resulted in a significantly increased detection rate for both giardia (118 versus 79 specimens, 49.4%; P = 0.006) and cryptosporidia (39 versus 23 specimens, 69.6%; P = 0.055).
在一项前瞻性比较研究中,在1年的时间里,连续对2696份新鲜粪便标本进行了检测,采用直接免疫荧光单克隆抗体染色法(针对未离心标本)和传统染色方法(用氯唑黑E检测贾第虫包囊,用改良金胺酚抗酸染色法检测隐孢子虫卵囊)检测蓝氏贾第鞭毛虫和微小隐孢子虫。直接免疫荧光单克隆抗体法使贾第虫(118份标本对79份标本,49.4%;P = 0.006)和隐孢子虫(39份标本对23份标本,69.6%;P = 0.055)的检出率均显著提高。
