Dérmal leishmaniasis in the Amazon region of Brazil: Leishmania (Viannaia) lainsoni sp. n., a new parasite from the State of Pará

Tetracycline and trimethoprim/sulfamethoxazole at clinical laboratory: can they help to characterize Staphylococcus aureus carrying different SCCmec types?

“…Gil et al 3 complement that the high number of L. davisi captured in Shannon-type traps reflects its anthropophilic habit, while Azevedo et al 19 reports that the high L. whitmani density may be associated with the changes in the original vegetation and the better adaptation to new environmental conditions. In the areas studied other vectors of ACL were identified, such as L. flaviscutellata, the main vector of Leishmania (Leishmania) amazonensis, which has been also found to be parasitized by Leishmania (Viannia) guyanensis in the French Guiana 24 ; L. umbiquitalis, the vector of Leishmania (Viannia) lainsoni in Brazil 25 ; L. complexa, species considered to be a Leishmania (Viannia) braziliensis vector 26 ; Leishmania carrerai is considered to be a Leishmania (Viannia) braziliensis vector according to Grimaldi et al 27 , who has characterized the parasite in phlebotomine sandflies as naturally infected in the Brazilian Amazon.…”

“…Leishmania (V.) lainsoni was first isolated near a rubber plantation in Pará from a human case of LCL 33 and then on the Island of Tocantins from the skin of Agouti paca. The asymptomatic nature of this infection led Silveira and others to suggest that this rodent might constitute a primary host of L. (V.) lainsoni in the Amazon region.…”
