旅游者腹泻是出国旅行者中报告的主要感染性疾病。在致病的微生物中,细菌约占61％。气单胞菌属的种类较多,目前至少有16种DNA杂交群,气单胞菌引起的传染病包括胃肠道感染和肠外感染。虽报告有无症状携带者,但几项病例对照研究显示,这些细菌可导致腹泻。随着基因分型技术的发展,对气单胞菌的鉴定也得到改进。作者对气单胞菌的流行率、地理分布、临床特征及抗生素疗效进行了研究。 Traveler diarrhea is a major infectious disease reported by travelers abroad. In pathogenic microorganisms, bacteria account for about 61%. There are more types of Aeromonas. At present, there are at least 16 DNA hybrids. Infectious diseases caused by Aeromonas include gastrointestinal tract infections and extraintestinal infections. Although there are reports of asymptomatic carriers, several case-control studies have shown that these bacteria can cause diarrhea. With the development of genotyping technology, the identification of Aeromonas has also been improved. The author of Aeromonas prevalence, geographical distribution, clinical features and antibiotic efficacy were studied.
