Camara Coelho LI, Paes M, Guerra JA, Barbosa Md, Coelho C, Lima B, Brito ME, Brandão Filho SP - Parasitol. Res. (2010)

Bottom Line: The most prevalent species was L. (V.) guyanensis.The principal finding of this study was the important quantity of infections involving more than one parasite species, representing 14% (29/209) of the total.The findings obtained in this work regarding the parasite are further highlighted by the fact that these isolates were obtained from clinical samples collected from single lesions.

ABSTRACT
In the State of Amazonas, American tegumentary leishmaniasis is endemic and presents a wide spectrum of clinical variability due to the large diversity of circulating species in the region. Isolates from patients in Manaus and its metropolitan region were characterized using monoclonal antibodies and isoenzymes belonging to four species of the parasite: Leishmania (Viannia) guyanensis, 73% (153/209); Leishmania (Viannia) braziliensis, 14% (30/209); Leishmania (Leishmania) amazonensis, 8% (17/209); and Leishmania (Viannia) naiffii, 4% (9/209). The most prevalent species was L. (V.) guyanensis. The principal finding of this study was the important quantity of infections involving more than one parasite species, representing 14% (29/209) of the total. The findings obtained in this work regarding the parasite are further highlighted by the fact that these isolates were obtained from clinical samples collected from single lesions.

Mentions: A total of 209 Leishmania spp samples were isolated and characterized. The majority of the isolates, 61.2% (128/209), originated from patients who resided in Manaus, with 38.8% (81/209) residing in the metropolitan regions (Fig. 1). The direct parasitological exam by scarification was positive in 85.2% (178/209) of cases.Fig. 1
