Serratia marcescens

Abstract

During the 24-month period ending September 1969, a total of 662 isolates of Serratia marcescens were obtained from 314 patients. In 97% of the patients, isolates were from the urinary tract and this seemed to be the most common portal of entry. Blood was the second most common source of isolates, and 12 patients with septicemia had a mortality of 33% (4). In one instance Serratia septicemia was secondary to an infected prosthetic aortic valve.
