Abstract

It is a commonly held opinion that acid-fast staining of urine or gastric aspirates is not a reliable indicator of mycobacterial disease because of the presence of saprophytic mycobacteria. In order to determine the clinical usefulness of acid-fast staining of these body fluids, we reviewed our 10-yr experience with acid-fast stains. Forty-seven of 5,829 urine specimens (0.8%) and 39 of 309 gastric aspirates (12.6%) yielded mycobacteria on culture. Twenty-three urine specimens and 12 gastric aspirates had positive acid-fast stains. Of these, only one possible false positive acid-fast stain of urine (less than 1%) was found and none was found in gastric aspirates. Thus, acid-fast stains of urine and gastric aspirates are, when positive, reliable indicators of true mycobacterial disease.

摘要

人们普遍认为，由于腐生性分枝杆菌的存在，尿液或胃抽吸物的抗酸染色不是分枝杆菌病的可靠指标。为了确定这些体液抗酸染色的临床实用性，我们回顾了我们10年来抗酸染色的经验。5829份尿液标本中有47份（0.8%），309份胃抽吸物中有39份（12.6%）培养出分枝杆菌。23份尿液标本和12份胃抽吸物抗酸染色呈阳性。其中，仅发现1份可能的尿液抗酸染色假阳性（不到1%），胃抽吸物中未发现假阳性。因此，尿液和胃抽吸物的抗酸染色若呈阳性，则是真正分枝杆菌病的可靠指标。
