Notes from the field: respiratory diphtheria-like illness caused by toxigenic Corynebacterium ulcerans --- Idaho, 2010.
Centers for Disease Control and Prevention (CDC)
MMWR Morb Mortal Wkly Rep. 2011;60(3):77.
On September 12, 2010, the Idaho Department of Health and Welfare was notified of a case of respiratory diphtheria-like illness in an Idaho man aged 80 years whose pharyngeal specimens yielded Corynebacterium ulcerans. Although C. ulcerans is zoonotic, the patient reported no animal contact or consumption of an unpasteurized dairy product. His vaccination history was unknown. Respiratory diphtheria-like illness from C. ulcerans is uncommon but has been reported in industrialized countries where respiratory diphtheria is rare. The last case of diphtheria-like illness caused by C. ulcerans in the United States was reported in 2005.
