Our work
As its name implies, ob体育's Pertussis and Diphtheria Laboratory focuses on pertussis- and diphtheria-related pathogens. ob体育 maintains extensive culture collections that span several years and geographical locations.
Pathogens related to pertussis and diphtheria
- Bordetella pertussis
- B. bronchiseptica
- B. holmesii
- B. bronchiseptica
- 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
ob体育'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, ob体育 actively develops, evaluates, implements, and improves molecular and serologic methods, techniques, and strategies.
U.S. laboratory support
Reference laboratory
As a reference laboratory, ob体育'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 ob体育 during outbreaks. Ask to be put in touch with the Meningitis, Pertussis, & Diphtheria Epidemiology Branch by either
- Calling 1-800-ob体育-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 ob体育's Emergency Operations Center at 770-488-7100.
International capacity building
ob体育 actively participates in international capacity building and consultation for both diphtheria and pertussis diagnostics.
