Prior to the advent of the Haemophilus influenzae type b vaccine, invasive infections due to H. influenzae type f were rarely described. However, the epidemiology of H. influenzae is changing. While the incidence of invasive infections due to H. influenzae is declining in children, such infections are becoming more common in adults, particularly in the elderly. Here, we report an unusual case of infective aortic aneurysm caused by H. influenzae type f that underlines the emerging clinical relevance and pathogenic capability of this organism.
在乙型流感嗜血杆菌疫苗问世之前，f 型流感嗜血杆菌引起的侵袭性感染很少被描述。然而，流感嗜血杆菌的流行病学正在发生变化。虽然儿童感染流感嗜血杆菌引起的侵袭性感染的发病率正在下降，但这种感染在成人中越来越常见，特别是在老年人中。在这里，我们报告了一例由 f 型流感嗜血杆菌引起的感染性主动脉瘤的罕见病例，这凸显了该病原体的新出现的临床相关性和致病能力。
