Lactose-positive Vibrio is a recently recognized marine organism that has pathogenic potential for humans. An organism was isolated from the sputum and blood of a man who was resuscitated after drowning in the sea. The isolates from both sources had the characteristics of lactose-positive Vibrio, which include positive oxidase, citrate, indole, and o-nitrophenyl-beta-D-galactopyranoside reactions and negative Voges-Proskauer, urease, and sucrose reactions. Seawater samples from 21 sites around Galveston Island were cultured for lactose-positive Vibrio over a period of 4 weeks, and 36% of the samples yielded the organism. The environmental isolates were very similar to the clinical isolates in biochemical reactions and susceptibility to antimicrobial agents. The results indicate that lactose-positive Vibrio is a common organism in the marine environment and that it should be considered in the diagnosis of infections, including pneumonia, associated with exposure to the sea.
乳糖阳性弧菌是一种最近才被认识的海洋生物，对人类具有致病潜力。从一名在海中溺水后复苏的男子的痰液和血液中分离出了一种微生物。来自这两个来源的分离株都具有乳糖阳性弧菌的特征，包括氧化酶、柠檬酸盐、吲哚和邻硝基苯-β-D-吡喃半乳糖苷反应呈阳性，而Voges-Proskauer、脲酶和蔗糖反应呈阴性。在4周的时间里，对加尔维斯顿岛周围21个地点的海水样本进行了乳糖阳性弧菌培养，36%的样本培养出了这种微生物。环境分离株在生化反应和对抗菌药物的敏感性方面与临床分离株非常相似。结果表明，乳糖阳性弧菌是海洋环境中的常见生物，在诊断与接触海水相关的感染（包括肺炎）时应考虑到它。
