Abstract

Streptococcus dysgalactiae has two main subspecies: S. dysgalactiae subsp. equisimilis (SDSE) and S. dysgalactiae subsp. dysgalactiae (SDSD). SDSE often colonizes and causes infections in humans; however, SDSD is an animal pathogen which often causes pyogenic infection in domestic animals. We present a case of meningitis with SDSD and herpes simplex virus in a 22-day-old newborn baby who had no exposure to animals.

Figure

  • Fig. 1 Brain diffusion-weighted magnetic resonance imaging scan of 23-day-old baby at hospital day 2. Focal seizures occurred on the second hospital day. The scan revealed multifocal diffusion restricted lesions at left frontotemporoparietal lobes (A, B, arrow).

  • Fig. 2 Brain magnetic resonance diffusion scan at 3 months of age, 2 months after treatment. It showed old infarcts with more cystic changes at left frontotemporoparietal lobes (arrow).
