摘要 在胃分泌物中发现了一种新的革兰氏阴性细菌——幽门螺杆菌。鉴于吸入性肺炎中不明革兰氏阴性菌的发生率接近 9%，作者着手证明气管分泌物中可以发现幽门螺杆菌。研究人员对 18 名连续入住重症监护病房且接受气管插管或鼻胃插管 24 小时或更长时间的患者进行了研究。在 18 名患者的 20 组标本中，从 2 份（10%）气管内标本中回收到螺杆菌。作者得出的结论是，幽门螺杆菌可以进入支气管内树，因此可能导致未知革兰氏阴性菌引起的肺炎的起源。
Abstract A new gram-negative bacterium, Helicobacter pylori, has been found in gastric secretions. In view of an almost 9% incidence of unidentified gram-negative bacteria in aspiration pneumonia, the authors set out to prove thatH pylori could be found in tracheal secretions. Eighteen sequential patients admitted to the intensive care unit who had endotracheal or nasogastric intubation for 24 hours or longer were studied. Of 20 sets of specimens from 18 patients, Helicobacter was recovered from 2 (10%) of the endotracheal specimens. The authors conclude that H pylori can gain access to the endobronchial tree and therefore may contribute to the origin of pneumonia due to unidentified gram-negative bacteria.
