Our work

As its name implies, ÐÇ¿ÕÓéÀÖ¹ÙÍø's Pertussis and Diphtheria Laboratory focuses on pertussis- and diphtheria-related pathogens. ÐÇ¿ÕÓéÀÖ¹ÙÍø maintains extensive culture collections that span several years and geographical locations.

Pathogens related to pertussis and diphtheria

Pertussis
  • Bordetella pertussis
  • B. bronchiseptica
  • B. holmesii
  • B. bronchiseptica
Diphtheria
  • Corynebacterium diphtheriae
  • C. pseudotuberculosis
  • C. ulcerans

Key activities

Key activities for the Pertussis and Diphtheria Laboratory include:

  • Researching new and improved laboratory methods
  • Helping U.S. laboratories, including in response to outbreaks
  • Building international diagnostic capacity

Innovative laboratory research

ÐÇ¿ÕÓéÀÖ¹ÙÍø's Pertussis and Diphtheria Laboratory works to enhance the diagnosis and surveillance of agents that cause pertussis or diphtheria.

The laboratory does that by researching methods to improve laboratory testing capabilities. Specifically, ÐÇ¿ÕÓéÀÖ¹ÙÍø actively develops, evaluates, implements, and improves molecular and serologic methods, techniques, and strategies.

U.S. laboratory support

Reference laboratory

As a reference laboratory, ÐÇ¿ÕÓéÀÖ¹ÙÍø's Pertussis and Diphtheria Laboratory supports U.S. health departments and public health laboratories with

  • Pathogen isolation and identification from clinical specimens
  • Outbreak response
  • Priority public health concerns

Pathogen isolation and identification

Related to Bordetella and Corynebacterium, the laboratory can offer advice concerning laboratory procedures dealing with

  • Isolation and identification of organisms from clinical specimens
  • Detection of organisms by polymerase chain reaction
  • Testing serum for immunoglobulin G antibodies to pertussis toxin
  • Molecular characterization of organisms by next generation sequencing

U.S. health departments and public health laboratories can request assistance with isolation, identification, and molecular characterization when pertussis or diphtheria is suspected.

Why it's important

Confirming B. pertussis in the laboratory can be difficult. This difficulty contributes to under-reporting of disease. Problematic testing for B. pertussis can compromise

  • Prevention programs
  • Surveillance activities
  • Vaccine effectiveness studies
  • Outbreak management

Outbreak response

Health departments can request assistance from ÐÇ¿ÕÓéÀÖ¹ÙÍø during outbreaks. Ask to be put in touch with the Meningitis, Pertussis, & Diphtheria Epidemiology Branch by either

  • Calling 1-800-ÐÇ¿ÕÓéÀÖ¹ÙÍø-INFO

The branch will make sure various experts, including laboratorians, are engaged based on the specific needs of each outbreak.

Priority public health concerns

Upon request, the laboratory can test for the presence of diphtheria toxin by the Elek assay for C. diphtheriae and C. ulcerans isolates.

If there's a suspected diphtheria case that requires assistance, call ÐÇ¿ÕÓéÀÖ¹ÙÍø's Emergency Operations Center at 770-488-7100.

International capacity building

ÐÇ¿ÕÓéÀÖ¹ÙÍø actively participates in international capacity building and consultation for both diphtheria and pertussis diagnostics.
