Etiological agent of cutaneous leishmaniasis

Question

Write down the etiological agent of the cutaneous leishmaniasis? How disease transmitted and what are its typical manifestations?

Answer 1

The etiological agent of the cutaneous leishmaniasis is protozoan Leishmania braziliensis. The transmission, like in the visceral form of disease, is by bite of sand fly Lutzomya (named after Brazilian scientist Adolfo Lutz), the vector host. Cutaneous leshmaniasis develops in bite site where parasite establishes itself. The skin wound has the volcanic crater shape, a reddish injury with raised borders. From primary lesions the parasites can spread throughout the blood to influence other areas, mainly mucosae of nose, pharynx and mouth, causing facial deformations.
