Enterococcus cecorum (formerly Streptococcus
cecorum), originally isolated from poultry intestines, has rarely
been encountered in human diseases. A 60-year-old man with liver
cirrhosis and hepatocellular carcinoma developed peritonitis on the
seventh day of his hospitalization. Cultures of one blood sample and
one ascites fluid sample obtained on that day both grew E. cecorum. The patient received intravenous cefoxitin therapy and
initially responded well. Unfortunately, another episode of peritonitis associated with septic shock developed 24 days after the start of
treatment, and culture of one blood specimen yielded the same organism.
The isolates were identified by the conventional biochemical tests, the
API Rapid ID 32 Strep system, and the API ZYM system (both systems from
bioMerieux, Marcy L'Etoile, France) and were further confirmed by
cellular fatty acid chromatography and 16S rRNA gene partial
sequencing. The identical biotype, antibiotype, and random amplified
polymorphic DNA pattern of the three isolates documented the long-term
persistence of this organism in the patient. To the best of our
knowledge, this is the first clinical description of recurrent
bacteremic peritonitis caused by E. cecorum.
