Indole spot tests using isolated, nonhemolytic colonies of Haemophilus species were positive for 90 of 151 (60%) respiratory isolates of Haemophilus influenzae, whereas 67 to 72 (93%) isolates of H. influenzae from cerebrospinal fluid and blood specimens were indole positive. Only 4 of 117 (3%) Haemophilus parainfluenzae isolates were positive for indole spot tests. Thus, indole-positive, nonhemolytic Haemophilus isolates in respiratory cultures can be presumptively identified as H. influenzae.
使用流感嗜血杆菌分离出的非溶血菌落进行吲哚斑点试验，结果显示，151株呼吸道流感嗜血杆菌分离株中有90株（60%）呈阳性，而从脑脊液和血液标本中分离出的67至72株（93%）流感嗜血杆菌吲哚试验呈阳性。117株副流感嗜血杆菌分离株中只有4株（3%）吲哚斑点试验呈阳性。因此，呼吸道培养中吲哚试验呈阳性的非溶血嗜血杆菌分离株可初步鉴定为流感嗜血杆菌。
