Abstract

To assess the role of aquaria in the epidemiology of aeromonas associated gastroenteritis, the prevalence and antibiotic susceptibility of aeromonads in ornamental aquaria were determined and compared to that of isolates obtained from patients with gastroenteritis. Thirty-eight (76%) of 50 aquaria, including those located in our hospital, yielded 61 isolates: 24 (39.3%) Aeromonas sorbria, 18 (29.0%) A. hydrophila, 15 (24.6%) A. caviae, and four (6.5%) which could not be speciated. In comparison, 41 (65%) of 63 faecal isolates were A. caviae. The aquarium isolates, in contrast to enteric isolates, were generally resistant to chloramphenicol, tetracycline, and trimethoprim/sulphamethoxazole. These findings indicate aquaria are unlikely sources of aeromonas-associated gastroenteritis, but their role as possible reservoirs for non-enteric infections with aeromonads needs to be defined.

摘要

为评估水族箱在气单胞菌相关肠胃炎流行病学中的作用，测定了观赏水族箱中气单胞菌的患病率和抗生素敏感性，并与从肠胃炎患者分离出的菌株进行比较。50个水族箱中有38个（76%），包括我院内的水族箱，分离出61株菌株：24株（39.3%）嗜水气单胞菌、18株（29.0%）嗜水单胞菌、15株（24.6%）豚鼠气单胞菌，4株（6.5%）无法鉴定。相比之下，63份粪便分离株中有41株（65%）为豚鼠气单胞菌。与肠道分离株相比，水族箱分离株通常对氯霉素、四环素和甲氧苄啶/磺胺甲恶唑耐药。这些发现表明，水族箱不太可能是气单胞菌相关肠胃炎的来源，但其作为气单胞菌非肠道感染可能储存库的作用有待明确。
