Leishmania infantum versus Leishmania chagasi: do not forget the law of priority

Characterization of Leishmania infantum species in dogs from the urban area of Cuiabá, State of Mato Grosso, Brazil

“…In different clinical samples of dogs selected by the Cuiabá ZCC that presented clinical, epidemiological and laboratorial evidence compatible with VL, the species responsible was confirmed as L. (L.) infantum. Its taxonomy was in agreement with the law of priority for the classification of microorganisms 15 .…”

Evaluation of Leishmania Species Reactivity in Human Serologic Diagnosis of Leishmaniasis

“…We recurred to both techniques to measure the levels of anti-Leishmania immunoglobulins in the sera of 10 Surinamese cutaneous leishmaniasis patients caused by Leishmania (Viannia) guyanensis (cutaneous leishmaniasis New World [CLN]) 13 , which presented one to three lesions on their extremities and 10 Afghan cutaneous leishmaniasis patients, with chronic single to few lesions on extremities caused by Leishmania major (cutaneous leishmaniasis Old World [CLO]). In addition, we included 10 Indian visceral leishmaniasis patients, caused by Leishmania donovani (VL [Ld]) and 10 Brazilian visceral leishmaniasis patients, caused by Leishmania infantum (= Leishmania chagasi ) 14 [VL (Li)], all patients with clinical symptoms. Written informed consent was obtained from all patients included in this study.…”

Differential protein abundance in promastigotes of nitric oxide‐sensitive and resistant Leishmania chagasi strains

“…Visceral leishmaniasis affects approximately half a million people and leads to about 50.000 deaths worldwide annually . Leishmania (Leishmania) infantum‐chagasi causes American visceral leishmaniasis (AVL), a zoonosis mainly transmitted by the sand fly vector Lutzomyia longipalpis (Psychodidae: Phlebotominae) . Over 90% of AVL cases occur in Brazil, where AVL‐AIDS coinfection has been reported .…”

“…An analogous epidemiological profile is found in the case of L. infantum in the Mediterranean basin. L. infantum and L. chagasi are generally considered members of the same species .…”
