Abstract
Abnormalities in cerebrospinal fluid associated with meningitis due to Haemophilus injluenzae type b were characterized in infant rats. After intranasal inoculation of bacteria, the development of intense bacteremia (> 104 colony-forming unitsjml) correlated with cultures of cerebrospinal fluid positive for H. infiuenzae, with pleocytosis, and with histologic evidence of meningitis. The degree of pleocytosis was related to the age of the animal, the amount of time since inoculation, and the severity of the meningitis.Keywords
