Necrotizing fasciitis is a life- and limb-threatening soft tissue infection. Due to its underlying predisposition and rapid progression, treatment should be started quickly using antibiotherapy and surgical intervention. ⋯ Other peptostreptococci have been reported as necrotizing fasciitis agents in the literature, though we encountered no cases of necrotizing fasciitis caused by Ruminococcus productus. Here, we describe a case of necrotizing fasciitis caused by R. productus, a Gram-positive, obligatory anaerobe.

A retrospective review was conducted of patients with external ventricular drains (EVDs) in situ in order to ascertain the utility of daily cerebrospinal fluid (CSF) analysis in such patients. All laboratory requests for CSF analysis, which were sent to the Microbiology Department, Auckland City Hospital, New Zealand, were reviewed to identify patients with EVDs in situ. The patients' clinical records were reviewed and information was obtained regarding their age, ethnicity, indication for EVD, duration of EVD, CSF analysis results, daily temperatures, Glasgow Coma Scale (GCS) and the presence of other infections. ⋯ Coagulase-negative staphylococci and Staphylococcus epidermidis were the most common isolates and were associated with ventriculitis approximately half of the time. Gram-negative isolates were less frequently isolated, but, when present, were always associated with ventriculitis. This study found that patient temperature and GCS did not allow early prediction of EVD-associated ventriculitis.
