Corynebacterium Diphtheriae is Inactivated by Germicidal UV-C Light

April 13, 2020 By Charles Boehme

Updated on May 22, 2020

C diphtheriae is Inactivated by UV-C Light

Germicidal ultraviolet light emitted from UV-C lamps inactivates many bacteria, mold, and virus that may be present in the air, on surfaces, and in water. Our products use STER-L-RAY® Germicidal UV-C Lamps Opens in New Window producing ultraviolet wavelengths at 254 nanometers, the region of germicidal effectiveness most destructive to harmful microorganisms including Corynebacterium diphtheriae, also known as C. diphtheriae.

C. diphtheriae Classification & UV Dose for Inactivation

Organism:Alternate Name:Type:Disease:UV Dose*:
Corynebacterium diphtheriaeC. diphtheriaeBacteriaDiphtheria6.50 mJ/cm2

C. diphtheriae can produce a toxin causing the disease diphtheria. It can get into and attach to the lining of the respiratory system. When that happens, it may cause weakness, sore throat, fever, or swollen glands in the neck. Within two to three days, it can produce a thick, gray coating that inhibits breathing or swallowing. On limbs, C. diphtheriae can produce lesions covered by a gray-brown membrane. The poison can also cause paralysis and congestive heart failure if distributed through the bloodstream. 

Diphtheria spreads from person to person, usually through respiratory droplets from coughing or sneezing. People can also get diphtheria by coming in contact with an object or surface that has C. diphtheriae on it and then touching their eyes, nose, or mouth. Rarely, someone can get the disease from either touching open sores, or touching the clothes of someone having open sores from diphtheria.
