Leishmaniasis in Panama

The following background data on Leishmaniasis in Panana are abstracted from Gideon and the Gideon e-book series. [1,2]

Time and Place:
– Most cases are reported from western Panama – Bocas del Toro, Cocle, Colon, Chiriqui and Panama Provinces.
– Children and new settlers to forest areas are at highest risk.

Infecting species:
– Leishmania mexicana amazonensis and L. braziliensis panamanensis are implicated.
– L. colombiensis is also encountered.
– L. naiffi has been identified in sand flies the region of the Canal Zone.

– Leishmania braziliensis has been identified in the two-toed sloth (Choloepus hoffmanni) and three-toed sloth (Bradypus infuscatus.
– The two-toed sloth has also been identified as a reservoir for Leishmania panamensis and L. colombiensis.
– Parasites have also been demonstrated in the night monkey (Aotus trivirgatus).
– Dogs may also act as natural reservoirs in this country. 3% of dogs in forest settlements are infected (1968 to 1973).

– The principal local vector for L. panamensis is Lutzomyia (Nyssomyia) trapidoi.
– Additional species of anthropophilic sandflies have been implicated, including Lu. (N.) ylephiletor, Lu. (Ps.) panamensis, Lu. ovallesi, Lu. (Ps.) shannoni, and Lu. gomezi.
– The predominant vectors in Gamboa (central Panama) are Lu. (Ps.) panamensis and Lu. gomezi.
