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

Authorship SCIMAGO INSTITUTIONS RANKINGS

ABSTRACT

INTRODUCTION:

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.

Keywords:
Polymerase chain reaction; Leishmania ( Viannia ); Leucocyte
