Identification for clinical purposes of the etiological germs in individual cases of bronchopulmonary not tuberculous infections is usually very hard. Sometimes, particularly in acute cases, microbiological counts in sputum as in tracheobronchial secretions and exudates may be useful. In some chronic cases an amount of particular bacteria in tracheal (transcutaneous) secretion larger than in sputum is to consider an etiological sign.
临床上鉴定非结核性支气管肺部感染个体病例中的病原微生物通常非常困难。有时，特别是在急性病例中，痰液以及气管支气管分泌物和渗出物中的微生物计数可能会有所帮助。在一些慢性病例中，气管（经皮）分泌物中某种特定细菌的数量多于痰液中的数量，这被视为病因学迹象。
