Please contact Frank Steurer about all laboratory issues related to diagnosing leishmaniasis – such as questions about obtaining culture medium from CDC, collecting specimens for various types of testing, shipping specimens to CDC (including the address and forms to use) and getting test results. Each situation/case should be individualized, with expert consultation. Contact information Frank Steurer CDC, Parasitic Diseases Branch 1600 Clifton Road, Mailstop D-64 (bldg 23, room 9-439) Atlanta, GA 30329 phone: 404-718-4175 email: fsteurer@cdc.gov fax: 404-718-4195

Collection Instructions
| Specimen: | Leishmania: bone marrow, cutaneous ulcer aspirates, tissue biopsies, and tissue fluid aspirates. Trypanosoma: Aspirates, tissue. |
| Collection Instructions: |
If possible, request culture medium before obtaining tissue specimens. CDC can provide tubes of culture medium by overnight express mail. Keep the tubes refrigerated until they are used; bring to room temperature shortly before inoculation. Once inoculated, keep at room temperature and mail to CDC as soon as possible, by overnight mail (preferably for arrival within 24 hours of when the specimens were obtained). Do not ship cultures on cold packs or dry ice, but keep the cultures away from heat.
If culture medium was not obtained in advance, consult CDC to discuss the options below: · If possible, place the specimen in tube/vial that contains a sterile buffered medium (e.g., buffered saline, RPMI, Eagle’s growth, Schneider’s, Tobie’s) with a neutral pH (~7-7.4). Use enough fluid to cover the specimen. Ship at room temperature, if the specimen will arrive at CDC within 24-48 hours. Otherwise, consult CDC about whether to refrigerate and ship on a cold pack, to minimize the potential for overgrowth of skin flora. (Of note, leishmanial culture medium from CDC contains antimicrobial agents.) · If no buffered medium is available, place the specimen in a sterile tube/vial; refrigerate the specimen and ship it on a cold pack by overnight mail to CDC.
