== Study Questions ==
* <spoiler text="What is the most common etiologic agent that causes bacterial meningitis?">The specific etiologic agent varies with the age of the patient:
* in neonates: the organisms include Escherichia coli and the group B streptococci;
* in infants and children: S. pneumoniae and N. meningitidis pervade in immunized children (H. influenzae type b (Hib) vaccine is routine in the U.S.), while Haemophilus influenzae is more prominent in non-immunized children;
* in adolescents and in young adults: Neisseria meningitidis;
* in the elderly: Streptococcus pneumoniae and Listeria.</spoiler>
* <spoiler text="What organism caused meningitis in this case and why?">Burn patients are at high risk for developing Pseudomonas infections. In this case, the patient was debilitated due to the extensive severe burn and developed a Pseudomonas septicemia which then led to the Pseudomonas meningitis.</spoiler>
* <spoiler text="Why is there fibrin in these lesions?">Because of the acute inflammatory reaction, there is extravasation of fibrin as well as the recruitment of neutrophils.</spoiler>
