Specimen Requirements for Haemophilus ducreyi
The Clinical Guide to Services is a comprehensive reference guide of testing services, shipping information, and submission requirements for Minnesota’s Infectious Disease Laboratory.
Even though there are ongoing efforts to keep information current, some information may not be up to date due to recent changes in testing procedures and/or regulation. Many of these tests are only available with prior approval from the Minnesota Department of Health.
If you cannot find what you are looking for in the guide, please Contact the Infectious Disease Laboratory.

- Sterile dacron-tipped swab is used by rolling firmly across the base of the ulcer.
- Cleaning before sampling is usually not necessary, unless the ulcers were covered with bloody transudates/pus resulted from secondary infections; if so the surface materials can be gently removed with a wet swab.
- If multiple ulcers exist different swabs should be used to avoid cross contamination from ulcer to ulcer.
- If only a single specimen will be collected select the largest ulcer with exudates.
- Express swab against the side of tube and discard.
