Enterococcus cecorum empyema thoracis successfully treated with cefotaxime

Patrick C Y Woo et al. J Clin Microbiol. 2004 Feb.

Abstract

We report the first case of Enterococcus cecorum empyema thoracis and spontaneous bacterial peritonitis in a 44-year-old man with underlying cirrhosis. The patient responded to cefotaxime (MIC, 0.25 microg/ml) treatment and drainage of the empyema. Susceptibility of E. cecorum to expanded-spectrum cephalosporins could be due to its production of types of penicillin-binding proteins similar to those produced by Streptococcus species rather than to those produced by Enterococcus species (as predicted by phylogenetic analysis of the 16S rRNA gene sequences).

Phylogenetic tree showing the relationships of the pleural fluid isolate species to other Enterococcus species, other representative Streptococcus species (S. pyogenes, S. mitis, S. agalactiae, S. intermedius, S. mutans, and S. bovis), G. adiacens, and A. defectiva. The tree was inferred from 16S rRNA data by the neighbor-joining method and rooted using the 16S rRNA gene sequence of S. aureus. Bootstrap values were calculated from 1,000 trees. The scale bar indicates the number of substitutions per 50 bases (estimated using the Jukes-Cantor correction). Names and accession numbers are given as cited in the GenBank database.
