* 投稿摘要: Aeromonas and Vibrio are gram-negative, facultative anaerobic, and lactose-fermenting bacilli. They occasionally cause gastroenteritis and sepsis via water contamination and wound infection, respectively. Usually, Vibrio can grow in TCBS argar and in medium with NaCl, and is sensitive to O129. In contrast, Aeromonas usually cannot grow in these media and is resistant to O129. A 66-year-old male patient with a history of lung cancer and hypertension visited our hospital due to fever and severe cough. Blood culture proved pyemia. The results of traditional and commercial identification tests revealed Vibrio which could grow in medium with NaCl, expressed yellow colonies on TCBS agar, and was susceptible to O129. V. chleroae was suspected. However, the results of the commercial kit, VITEK 2 system (bioMerirux, Marcyl’Etoile, France), showed V. alginolyticus and V. cholerae. The specific species could not be effectively identified. Vibrio multiplex PCR analysis for V. cholerae, V. vulnificus, and V. alginolyticus also didn’t yield any expected products. Then, 16S rDNA sequencing revealed 99% genome similarity to Aeromonas hydrophilia. Finally, the result of PCR analysis with specific primers to Aeromonas hydrophilia matched with it. Sometimes, we cannot correctly identify the specific species of some microorganisms, because of unexpected biochemical reaction. As long as the molecular techniques are available, we can not only effectively resolve the dilemma that we encounter with traditional and commercial methods but speed clinical diagnosis and treatment.
