Cholangitis with septic shock caused by Raoultella planticola.

Raoultella planticola (formerly Klebsiella planticola) is a Gram-negative bacterium that has been rarely reported in association with human infection. Here we describe a case of cholangitis complicated with septic shock caused by R. planticola in an immunocompromised patient with advanced cancer who underwent endoscopic retrograde cholangiopancreatography to extract common bile duct stones. The infection was cleared by piperacillin-tazobactam treatment.
