LOSADA M, HÉCTOR; MANTEROLA D, CARLOS; PINEDA N, VIVIANA  y  VIALG, MANUEL. Assessment of bacterial load in bile among patients with acute cholangitis . Rev Chil Cir [online]. 2006, vol.58, n.1, pp.35-39. ISSN 0718-4026.  http://dx.doi.org/10.4067/S0718-40262006000100009.

Background: The role that bile bacterial load plays in the physiopathology or the evolution of patients with cholangitis has not been well established. Aim: To assess the bacterial load and the most common bacteria infecting the bile of patients with acute gallstone cholangitis. Materials and Methods: A prospective series of patients over 18 years of age with acute gallstone cholangitis operated at Temuco Regional Hospital between December, 2004 and March, 2005. The bile cultures from the choledochus were placed in blood and MacConkey agar plates. Results: A total of 30 bile cultures were studied. In 25 cultures (83%) the bacterial load was over 105 colony forming units (CFU)/ml, four cultures (12.3%) had a bacterial load of less than 105 CFU/ml and one culture (3.4%) was negative. The most commonly isolated bacteria was Escherichia coli (53%), followed by Klebsiella pneumoniae (20%). All gram-negative bacteria were susceptible to either aminoglucosides or third-generation cephalosporins. All gram-positive bacteria were susceptible ampicillin or vancomycin. Conclusions: The bacterial load in patients with acute gallstone cholangitis is >105 CFU/ml in most cases. The most frequently isolated germ was Escherichia coli, followed by Klebsiella pneumoniae
