Neurologic listeriosis is not typically associated with a bacteremia. CNS infection is believed to and has been shown to result from localized entry of the bacteria via defects in the oral mucosa, with initial entry into the CNS via the trigeminal nerve. A systemic or bacteremic phase is not usually associated with this process. CSF or brain would be required to identify neurolisteriosis in most cases.Blood can be a good sample in monogastrics and neonates with septicemia. Placenta and fetal tissues are appropriate specimens in abortions cases.
