The bacterium Aeromonas hydrophila is commonly found in natural bodies of water, and is a potential invasive pathogen for those who suffer trauma while submerged in water. Five patients treated by the authors and 18 previously reported patients were reviewed to further define the characteristics of A. hydrophila wound infections. Although Aeromonas has been isolated from salt and brackish water, all 23 cases occurred following contact with fresh water. Signs of infection usually appeared 8-48 hours following puncture or laceration injury. The foot or leg were most commonly involved. Infection was frequently rapidly progressive; fascia, tendon, muscle, bone, or joint involvement occurred in 39% of cases. In addition to A. hydrophila, other aerobic and anaerobic bacteria were found in 48% of cases. Aeromonas infection should be suspected in cases of early and rapidly progressive wound infection following trauma in fresh water. Broad-spectrum antimicrobial therapy and appropriate surgical care should be promptly instituted.
嗜水气单胞菌通常存在于天然水体中，对于那些在水中受外伤的人来说，它是一种潜在的侵袭性病原菌。作者治疗的5例患者和先前报道的18例患者接受了回顾性研究，以进一步明确嗜水气单胞菌伤口感染的特征。尽管气单胞菌已从咸水和微咸水中分离出来，但所有23例病例均发生在接触淡水之后。感染迹象通常在穿刺或撕裂伤后8 - 48小时出现。足部或腿部最常受累。感染通常进展迅速；39%的病例发生了筋膜、肌腱、肌肉、骨骼或关节受累。除嗜水气单胞菌外，48%的病例还发现了其他需氧菌和厌氧菌。对于淡水创伤后早期且进展迅速的伤口感染病例，应怀疑气单胞菌感染。应立即开始广谱抗菌治疗和适当的外科护理。
