Leishmania tropica

Leishmania tropica is a species of flagellate parasites that infects humans and hyraxes, and the cause of the disease Leishmaniasis Recidivans, a form of cutaneous leishmaniasis.[1] L. tropica infection results in non-ulcerating disease.

Fusion and hybridization of different L. tropica strains can be efficiently induced in vitro by exposure of promastigotes (a stage of the life cycle) to DNA damage stress.[2] The fused cells do not undergo meiosis and are mostly tetraploid.[citation needed]
