b
Neisseria meningitidis (gram-positive diplococcus)
QuestionChoice
The CSF results with an increased white cell count consisting predominantly of neutrophils are consistent with bacterial meningitis. Neisseria meningitidis is one of the most common bacterial causes of meningitis and the rates are highest for young children, adolescents, and young adults. Neisseria meningitis is a gram-negative bacteria appearing in pairs on a gram stain, hence it is called a diplococcus.
