Gram stains of stools from patients with diarrhea and control patients with no diarrhea were examined for a predominance of gram-positive rods and the presence of polymorphonuclear leukocytes. Results were compared with those from lower gastrointestinal endoscopy for pseudomembranes. Clostridium difficile culturing, and C. difficile toxin assay. The Gram stain was moderately difficult to interpret and was not useful in diagnosing diarrheal disease associated with C. difficile.
对腹泻患者及无腹泻对照患者的粪便进行革兰氏染色,检查革兰氏阳性杆菌的优势情况及多形核白细胞的存在情况。将结果与下消化道内镜检查发现假膜、艰难梭菌培养及艰难梭菌毒素检测的结果进行比较。革兰氏染色的结果较难解读,对诊断与艰难梭菌相关的腹泻病并无帮助。
