Leishmania mexicana amazonensis


Leish·man·i·a mex·i·ca'n·a am·a·zo·nen·'sis

a particularly widespread form of Leishmania mexicana in the Amazon basin (Bolivia, Brazil, Colombia, Ecuador, and southern Venezuela), where it infects a variety of forest rodents, the reservoirs of human infection. The disease is rare in humans, but the single or multiple lesions, when induced, rarely heal spontaneously; the disseminated form is common, but nasopharyngeal involvement does not occur. The vector is the sandfly Lutzomyia flaviscutellata.
