Aeromonas species are ubiquitous, facultative, anaerobic, gram-negative flagellated rods, mainly found in aquatic ecosystems worldwide. Skin and soft-tissue infections, including cellulitis and wound infections, are the second most frequent location of isolations of Aeromonas spp. in clinical samples, after the gastrointestinal tract. All three major Aeromonas species (A. hydrophila, A. caviae, and A. veroni biotype sobria) have been associated with wound infections, but A. hydrophila predominates. Typically, infection occurs after trauma and subsequent exposure to contaminated fresh water or soil. However, Aeromonas folliculitis has been rarely reported. We report the first two pediatric cases of Aeromonas hydrophila folliculitis associated with the use of recreational water facilities that clinically and epidemiologically mimic Pseudomonas folliculitis. Clinical and microbiological studies may be necessary to clarify the role of Aeromonas spp. in this newly-reported infection.
气单胞菌属无处不在，是兼性厌氧革兰氏阴性鞭毛杆菌，主要存在于世界各地的水生生态系统中。皮肤和软组织感染，包括蜂窝织炎和伤口感染，是临床样本中气单胞菌属分离株的第二常见部位，仅次于胃肠道。所有三种主要气单胞菌（嗜水气单胞菌、豚鼠气单胞菌和维罗纳气单胞菌温和生物型）都与伤口感染有关，但嗜水气单胞菌占主导。通常，感染发生在创伤后并随后接触受污染的淡水或土壤。然而，气单胞菌毛囊炎很少有报道。我们报告了首例两例与使用娱乐性水设施相关的嗜水气单胞菌毛囊炎儿科病例，其临床和流行病学表现类似假单胞菌毛囊炎。可能需要进行临床和微生物学研究，以阐明气单胞菌属在这种新报道感染中的作用。
