LOSADA M, HÉCTOR et al. Microbiology of pancreatic abscesses in a Chilean Regional Hospital . Rev Chil Cir [online]. 2006, vol.58, n.1, pp.20-24. ISSN 0718-4026.

Background: Pancreatic infections during pancreatitis are caused by bacterial translocation of the intestinal flora into areas pancreatic necrosis. Thus, the main organisms involved are Echerichia coli in 25 to 35% of cases, Klebsiella spp in 10 to 25% and Enterobacter spp in 3% to 7%. Aim: To describe the microbiological features and antimicrobial sensitivity of pancreatic abscesses, operated at Temuco Regional Hospital. Materials and Methods: Subjects with a pancreatic abscess and operated in the surgical and emergency services of Temuco Regional Hospital between January 2004 and March 2005, were studied. The samples collected were incubated in blood and MacConkey agar plates. The in vitro sensitivity to antimicrobials was assessed using a qualitative method with sensidiscs for each antimicrobial. Results: Ten patients were studied. Serratia marcescens, Citrobacter freundii, Acinetobacter baumannii and Methicillin-Resistant Staphylococcus aureus were found, each in two cultures. Candida spp. was isolated from one culture. Forty percent of Gram-negative bacteria were sensitive to quinolones and all were sensitive to carbapenem. Conclusions: The most commonly isolated bacteria in pancreatic abscesses in our series were multiresistant gram-negative bacteria and Methicillin-Resistant Staphylococcus aureus
