The viability of the "in vitro" cultivation procedure as a practical tool for diagnosis and primary isolation of Leishmania braziliensis braziliensis. 2. A study of patients from endemic areas

Resumo

In vitro cultivation of Lbb is a useful method in the field for primary isolation of this leismanial subspecies. Cultures in biphasic blood agar media (DAB and Evans) and liquid media (Schneiders and AR 103) done in patients with cutaneous leismanias showed, 1. A similar sensibility in DAB and Schneiders medium when needle aspirates were used to seed the cultures; 2. That DAB medium performed well when compared "with Evans medium; 3. A rise in isolation of Lbb if 3 aspirations taken from different sites in the same lesion were cultivated (50% positivity with DAB medium).
