Cerebral Abscess caused by Novel Species: Streptococcus Pluranimalium

Streptococcus pluranimalium, a gram-positive aerobic coccus, has been isolated primarily from several farm animals. The pathogenicity of this species is not well characterised either in animals or humans. As per the literature, cases of S. pluranimalium infection in humans have been reported only a handful of times. We report the case of cerebral abscess caused by S. pluranimalium in a patient who presented with weakness and confusion. The diagnosis of cerebral abscess was made on imaging supported by microbiological culture. Burr hole procedure for abscess drainage followed by an antibiotic regimen based on culture and sensitivity results contributed to a successful outcome. The bacteria were identified by analytical profile index for Streptococci (API Strep) and VITEK 2 gram-positive cocci panel. The case was successfully treated with vancomycin.
