Fatal listeria meningitis in an immunocompromised infant: therapeutic implications.

Infection with Listeria monocytogenes is rare in infants and children. Listeriosis has been made a notifiable condition in the State of California since 1985. From January 1985 to December 1990, only seven cases of listeriosis have been reported in children less than or equal to 13 years of age. This brief report summarises the features of a fatal case of listeria meningitis in an immunocompromised 4-month-old infant, discusses diagnostic and therapeutic implications, and describes the other six cases.
