Detection of Leishmania (Viannia) DNA in leucocytes from the blood of patients with cutaneous leishmaniasis

ABSTRACTINTRODUCTION:Cutaneous leishmaniasis (CL) is a serious and global public health issue, with the potential of developing a mucosal form, occurring as subclinical cases, and showing recurrence despite previous treatment.METHODS:Polymorphonuclear and mononuclear DNA obtained from 49 patients wa...

Description
Summary:ABSTRACTINTRODUCTION:Cutaneous leishmaniasis (CL) is a serious and global public health issue, with the potential of developing a mucosal form, occurring as subclinical cases, and showing recurrence despite previous treatment.METHODS:Polymorphonuclear and mononuclear DNA obtained from 49 patients was subjected to polymerase chain reaction for detection of Leishmania (Viannia).RESULTS:DNA was detected in mononuclear cells from two patients with active primary lesions positive for CL, with infection periods of 3 and 6 months, respectively.CONCLUSIONS:The DNA of Leishmania (Viannia) indicates probable parasite dissemination possibly explaining subclinical case emergence, lesion recurrence, and mucosal lesion appearance.
