Despite numerous descriptions of body abscesses produced by Streptococcus milleri group bacteria, lung abscesses caused by this group remain under-reported and the clinical and laboratory features have yet to be fully characterised. We present the case of a patient admitted with lung multiple abscesses produced by Streptococcus constellatus.

ABSTRACT Previous studies of the antibiotic susceptibility ofStreptococcus milleri group organisms have distinguished among species by using phenotypic techniques. Using 44 isolates that were speciated by 16S rRNA gene sequencing, we studied the MICs and minimum bactericidal concentrations of penicillin, ampicillin, ceftriaxone, and clindamycin for Streptococcus intermedius, Streptococcus constellatus, and Streptococcus anginosus. None of the organisms was resistant to beta-lactam antibiotics, although a few isolates were intermediately resistant; one strain of S. anginosus was tolerant to ampicillin, and another was tolerant to ceftriaxone. Six isolates were resistant to clindamycin, with representation from each of the three species. Relatively small differences in antibiotic susceptibilities among species of the S. milleri group show that speciation is unlikely to be important in selecting an antibiotic to treat infection caused by one of these isolates.

Accident And Emergency Department

We present the case of a 61-year-old woman who presented to the accident and emergency department with an ischaemic stroke, on a background of receiving intravenous and oral antibiotics to treat chronic left sphenoid sinusitis. Initially presenting with right-sided weakness and aphasia, a diagnosis of acute ischaemic stroke was made. Antibiotics had been commenced 1 month prior to the ischaemic stroke. Imaging at that time showed changes in keeping with chronic sphenoid sinusitis along with a small dehiscence in the lateral wall of the left sphenoid sinus and thrombosis of the left superior ophthalmic vein. During that admission blood cultures grew Streptococcus constellatus, a member of the Streptococcus milleri group. We discuss the unusual aetiology of this stroke, the emerging evidence associating chronic rhinosinusitis with stroke and the complex multidisciplinary approach required for management in this case.
