Burkholderia cepacia complex is a Gram-negative opportunistic pathogen usually found in people with an immunocompromised condition such as cystic fibrosis (CF). In a tropical country like India, this organism has been associated with a number of hospital-acquired infections including sepsis. We present here a report of a case of Burkholderia vietnamiensis causing a non-lactational breast abscess in a non-CF patient. The pathogen was identified as B. cepacia using Vitek system and matrix-assisted laser desorption ionisation–time of flight. This was confirmed by polymerase chain reaction (PCR) using recA genus-specific gene and sequencing of the PCR amplicons. recA-restriction fragment length polymorphism and recA gene sequencing revealed that the isolate is B. vietnamiensis. This is the first description of B. vietnamiensis isolated from a clinical case from India.

越南伯克霍尔德杆菌在印度泰米尔纳德邦的一名非囊性纤维化患者中引起非哺乳期乳房脓肿



洋葱伯克霍尔德菌复合体是一种革兰氏阴性机会致病菌，通常见于患有囊性纤维化 (CF) 等免疫功能低下疾病的人群。在印度这样的热带国家，这种微生物与许多医院获得性感染（包括败血症）有关。我们在此报告一例越南伯克霍尔德杆菌导致非 CF 患者出现非哺乳期乳房脓肿的病例。使用 Vitek 系统和基质辅助激光解吸电离飞行时间将病原体鉴定为洋葱伯克霍尔德杆菌。使用recA属特异性基因的聚合酶链式反应(PCR)和PCR扩增子的测序证实了这一点。 recA限制性片段长度多态性和recA基因测序表明该菌株为越南芽孢杆菌。这是从印度临床病例中分离出的越南芽孢杆菌的首次描述。
