Invasive Aeromonas Infections Successfully Treated with Source Control and Antibiotics
Table of Contents
Overview
A recent case series documented accomplished treatment of invasive aeromonas infections at a rural hospital in the United States. The study, published in Surgical Infections in 2025, highlights the importance of prompt source control and appropriate antibiotic therapy in managing these potentially serious infections.
Study Details
Researchers retrospectively reviewed cases of invasive Aeromonas infections treated at their facility. The infections presented in diverse ways, including cholangitis, empyema, and soft tissue infections. The study included patients undergoing cholecystectomy, and laparoscopic cholecystectomy. Preferred antibiotic choices included fluoroquinolones,third or fourth-generation cephalosporins,trimethoprim-sulfamethoxazole,and doxycycline.
All infections were successfully treated with a combination of timely source control – such as surgical drainage or debridement – and appropriate antibiotic therapy. Notably, one patient died due to metastatic pancreatic cancer, but this was resolute to be unrelated to the Aeromonas infection.
Patient Demographics & Infection Types
While the study doesn’t provide detailed demographic data in the provided excerpt,it emphasizes the association between Aeromonas infections and underlying biliary disease. This suggests a potential risk for individuals with gallbladder issues or those who have undergone biliary surgery.
Implications for Clinical Practice
The findings underscore the need for clinicians to consider aeromonas infections in patients presenting with invasive disease, particularly those with biliary disease or soft tissue involvement. Early imaging is crucial to identify potential sources of infection, and surgical consultation should be considered promptly.
Empiric antibiotic therapy should address the possibility of polymicrobial infection, as Aeromonas infections can frequently enough occur in conjunction with other bacterial species.Antibiotic selection should be guided by local susceptibility patterns and tailored based on culture and sensitivity results.
Antibiotic recommendations
The study identified several antibiotic classes as effective in treating Aeromonas infections:
- Fluoroquinolones
- Third or Fourth Generation Cephalosporins
- Trimethoprim-Sulfamethoxazole
- Doxycycline
However, antibiotic susceptibility can vary geographically
