Abstract

The role of Aeromonas spp. in gastroenteritis is controversial due to varied clinical presentations and variable prevalence in asymptomatic. This study, conducted in Northern Israel, aimed to compare positivity rate and demographic characteristics of patients with Aeromonas-associated gastroenteritis (AAG) to asymptomatic, and examine the role of Aeromonas in AAG by comparing clinical and epidemiological characteristics between AAG and Campylobacter-associated gastroenteritis (CAG) patients.

Results showed that 4.24%-4.81% of AAG patients had Aeromonas spp. in stools as a sole pathogen in 2020-2022, compared to 4.9% of asymptomatic. Analysis of 243 CAG patients versus 70 AAG patients revealed significantly less diarrhea, fever, abdominal pain, and muscle pain in AAG patients. Multivariate analysis identified higher Ct values, recent restaurant dining, and prolonged diarrhea as predictive factors for AAG versus CAG.

In conclusion, similar positivity rates of Aeromonas spp. in symptomatic and asymptomatic making the distinction between true pathogen versus commensal bacteria difficult, unlike CAG.

以色列北部与气单胞菌相关的肠胃炎的流行病学和临床特征：对公共卫生的启示和影响。

由于临床表现各不相同，无症状者的发病率也不尽相同，因此对气单胞菌属在肠胃炎中的作用存在争议。本研究在以色列北部进行，旨在比较与气单胞菌相关的胃肠炎（AAG）患者和无症状患者的阳性率和人口统计学特征，并通过比较 AAG 和弯曲杆菌相关的胃肠炎（CAG）患者的临床和流行病学特征来研究气单胞菌在 AAG 中的作用。结果显示，2020-2022 年，4.24%-4.81% 的 AAG 患者粪便中的唯一病原体为气单胞菌，而无症状患者的这一比例为 4.9%。对 243 名 CAG 患者和 70 名 AAG 患者进行分析后发现，AAG 患者的腹泻、发热、腹痛和肌肉疼痛明显减少。多变量分析发现，较高的 Ct 值、近期在餐馆用餐和长时间腹泻是 AAG 与 CAG 的预测因素。总之，有症状和无症状患者的气单胞菌属阳性率相似，因此很难区分是真正的病原体还是共生菌，这一点与 CAG 不同。
