Septic shock caused by Plesiomonas shigelloides in a patient with sickle beta-zero thalassemia.

ABSTRACT

Invasive infection and extraintestinal complications are rarely caused by Plesiomonas shigelloides, a waterborne bacterium belonging to the Vibrionaceae family. We report a case of a 16-year-old female patient with sickle beta-zero thalassemia who survived septic shock caused by P. shigelloides associated with secondary acute respiratory distress syndrome and disseminated intravascular coagulation. Treatment with a carbapenem was successful, and the patient recovered without any sequelae. The previous reports of P. shigelloides sepsis are cited, and possible pathogenic mechanisms are discussed.
