Streptococcal meningitis following myelogram procedures.

In September of 2004, we investigated 7 cases of post-myelography meningitis. Streptococcal species were recovered from blood or cerebrospinal fluid in all cases. Our findings suggest that droplet transmission of the oral flora of the clinician performing the procedure was the most likely source of these infections. The Centers for Disease Control and Prevention recommends the use of face masks by those performing myelograms.
