Leishmania lainsoni: a peculiarVianniaspecies

Leishmania (Viannia) naiffi Lainson & Shaw 1989

“…Despite little knowledge about the distribution of this species, some characteristics of the parasite are intriguing, such as its exuberant growth in culture medium versus low replication after animal inoculation [6,37], and the highest number of copies of the M8 gene, metalloprotease leishmanolysin family (GP63) [39] versus the correlation of benign course of L. naiffi infection [15]. A putative hybrid between L. naiffi and L. lainsoni, the most divergent species classified in the subgenus Viannia [40], was isolated from a female living in the Brazilian Amazon region (Acre State) presenting a cutaneous lesion [41].…”

Genetic Data Showing Evolutionary Links between Leishmania and Endotrypanum

“…schaudinni and other Leishmania species. Leishmania (V.) lainsoni represents a very divergent monophyletic Viannia species, which was clustered as an independent complex (Thomaz-Soccol et al 1993, Cupolillo et al 1994, Fernandes et al 1995, Eresh et al 1995. The internal transcribed spacers of the rRNA gene were amplified by PCR and the product digested with several restriction enzymes (Cupolillo et al 1995).…”

Leishmania (Viannia) lainsoni (Silveira et al. 1987): ultrastructural aspects of the parasite and skin lesion in experimentally infected hamster (Mesocricetus auratus)

“…This protozoan has distinct biological (Silveira et al 1987;Corrêa et al 2005), biochemical (Cupolillo et al 1994) and molecular (Fernandes et al 1995;Fernandes et al 1996;McCann et al 1999;Corrêa et al 2006) characteristics, when compared to other species of the Viannia subgenus. Although this Leishmania species is an attractive model for biological studies, few are known about its evolutive forms, and ultrastructural analyses of experimental skin lesions are still lacking.…”
