Abstract

Pseudomonas pickettii strains were studied to determine the characteristics essential for their identification in the clinical microbiology laboratory. Preliminary investigations indicated that these glucose-oxidizing, denitrifying, gram-negative rods were quite similar to an unclassified group of clinical isolates designated VA-2. Gas liquid chromatography of trimethylsilyl derivatives of whole cell hydrolysates of P. pickettii and VA-2 strains yielded nearly identical elution profiles. The VA-2 cultures were concluded to be probable strains of P. pickettii. A method is presented for differentiating cultures of P. pickettii from other similar bacteria encountered in clinical specimens.

摘要

对皮氏假单胞菌菌株进行了研究,以确定在临床微生物实验室中鉴定它们所需的特征。初步调查表明,这些氧化葡萄糖、反硝化的革兰氏阴性杆菌与一组未分类的临床分离株(命名为VA - 2)非常相似。对皮氏假单胞菌和VA - 2菌株全细胞水解产物的三甲基硅烷基衍生物进行气相色谱分析,得到了几乎相同的洗脱图谱。得出结论,VA - 2培养物可能是皮氏假单胞菌菌株。本文介绍了一种将皮氏假单胞菌培养物与临床标本中遇到的其他类似细菌区分开来的方法。
