Plain-English summary

A 3-year-old spayed female mixed-breed dog was brought in for sudden and worsening neurological problems. Tests of her spinal fluid showed signs of infection, and she later developed liver issues, low platelet counts, and anemia, likely due to a medication she received. Although initial cultures didn't find any bacteria, a special test identified Streptococcus bacteria in her spinal fluid. After treatment for the streptococcal infection, the dog made a full recovery.

Abstract

A 3-year-old, spayed female, mixed-breed dog was evaluated for acute, progressive neurological disease. Analysis of cerebrospinal fluid (CSF) showed neutrophilic pleocytosis. The dog later developed liver disease, thrombocytopenia, and anemia that were presumably secondary to ceftriaxone administration. Bacterial cultures of blood, urine, and CSF were negative. However, a universal bacterial polymerase chain reaction assay of CSF identified deoxyribonucleic acid from Streptococcus spp. The dog recovered with therapy for streptococcal encephalitis.
