To investigate the potential usefulness of u.v. germicidal irradiation (UVGI) in preventing the spread of Burkholderia cepacia, an important pathogen in cystic fibrosis (CF), the in-vitro susceptibility of B. cepacia to UVGI was determined. Five strains were exposed to UVGI from a 7.2-W source. Burkholderia cepacia was less susceptible to UVGI than other important CF-related pathogens, namely Staphylococcus aureus and Pseudomonas aeruginosa, but was more susceptible than Stenotrophomonas maltophilia. No strain of B. cepacia survived longer than an 8 s exposure to UVGI, with doses required to achieve 1 log reduction in bacterial numbers ranging from 28.3 to 57.5 J m(-2).
为研究紫外线杀菌照射（UVGI）在预防洋葱伯克霍尔德菌传播方面的潜在作用，洋葱伯克霍尔德菌是囊性纤维化（CF）中的一种重要病原体，测定了洋葱伯克霍尔德菌对UVGI的体外敏感性。将五株菌株暴露于来自7.2瓦光源的UVGI下。与其他重要的CF相关病原体（即金黄色葡萄球菌和铜绿假单胞菌）相比，洋葱伯克霍尔德菌对UVGI的敏感性较低，但比嗜麦芽窄食单胞菌更敏感。没有一株洋葱伯克霍尔德菌在暴露于UVGI 8秒以上后存活，使细菌数量减少1个对数所需的剂量范围为28.3至57.5 J m(-2)。
