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.
