Haemophilus species, as a urinary tract pathogen, is rarely encountered. Routine urine culture pathogens are well documented to include Enterobacteriaciae, Enterococcus spp., Staphylococcus spp., Pseudomonas spp., and Candida spp. Pathogens encountered rarely in this context may include Corynebacterium ureolyticus and nonfermenting gram negative bacilli. This case study involves the finding of Haemophilus influenzae in a urine culture performed on a 4-year-old Caucasian girl and Haemophilus parinfluenzae in a 60-year-old African American man with pyelonephritis. Visualization of satellite colonies on blood agar was a key factor in finding H. influenza Awareness of the previous presence of Haemophilus spp. in a urine culture was instrumental in our finding of H. parainfluenzae 3 weeks later. These cases raise the question of how often Haemophilus spp. occur as urinary tract pathogens and under what circumstances one should actively perform cultures for them.
嗜血杆菌属作为泌尿道病原体很少见。常规尿培养病原体有充分记录，包括肠杆菌科、肠球菌属、葡萄球菌属、假单胞菌属和念珠菌属。在此背景下很少遇到的病原体可能包括解脲棒杆菌和非发酵革兰氏阴性杆菌。本病例研究涉及在一名4岁白种女孩的尿培养中发现流感嗜血杆菌，以及在一名60岁患有肾盂肾炎的非裔美国男性中发现副流感嗜血杆菌。血琼脂上卫星菌落的可视化是发现流感嗜血杆菌的关键因素。了解尿培养中先前存在嗜血杆菌属有助于我们在3周后发现副流感嗜血杆菌。这些病例提出了一个问题，即嗜血杆菌属作为泌尿道病原体的出现频率有多高，以及在何种情况下应该积极对其进行培养。
