“…In 2018, the CL detection coefficient in Amapá was 68.7/100,000 inhabitants, with autochthonous cases in 14 of the state's 16 municipalities. 3 Phlebotomine insects, which are potential CL vectors, are abundant in this Amazon subregion, 8,10,11 where CL is endemic. 2,3 In order to collect data, we recruited individuals attending the Amapá Tropical Diseases Reference Center between January and May 2018.…”

“…Study participants infected with L. guyanensis came from nine of the ten municipalities considered in the sample, suggesting widespread distribution of this species in Amapá, where vector fauna are abundant. 8,10,11 L. braziliensis and L. guyanensis infection caused by Leishmania RNA virus subtype 1, found in Peru, Bolivia, French Guiana, Suriname and Brazil, would explain the high virulence and resistance of these species to the drug. 23 Biological factors of CL need to be monitored, especially in frontier regions.…”

Objective: to investigate Leishmania species in a series of autochthonous cutaneous leishmaniasis (CL) cases in Amapá State, Brazilian Amazon. Methods: this was a descriptive ecological study carried out from January-October/2018 at a reference center for CL diagnosis in Amapá; individuals with CL receiving care from January-May/2018 were recruited; clinical data and skin biopsies were obtained; from extracted DNA (phenol-chloroform) we amplified the hsp70-234 gene region (PCR) for nucleotide sequencing (Applied Biosystems: ABI3500XL). Results: 38 individuals were interviewed, examined and diagnosed; men predominated (28/38; mean age=32.5±11.3); lesions (most ulcers: 37/38) measuring 0,4-10mm (34/38) and ≥11mm (4/38) were multiple in 20/38 individuals; diagnosis of L. braziliensis (1), L. naiffi (1), L. infantum (1), L. (Viannia) sp. (1), L. amazonensis (2) and L. guyanensis (32); individuals infected with L. guyanensis (32/38) lived in 9/10 municipalities represented in the sample, and 17/32 of these had multiple lesions. Conclusion: presence of Leishmania guyanensis predominated and was frequently associated with multiple lesions.

Biodiversity, threats and conservation challenges in the Cerrado of Amapá, an Amazonian savanna

An Amazonian savanna in northern Brazil known as the Cerrado of Amapá is under imminent threat from poor land-use planning, the expansion of large-scale agriculture and other anthropogenic pressures. These savannas house a rich and unique flora and fauna, including endemic plants and animals. However, the area remains under-sampled for most taxa, and better sampling may uncover new species. We estimate that only ~9.16% of these habitats have any kind of protection, and legislative changes threaten to further weaken or remove this protection. Here we present the status of knowledge concerning the biodiversity of the Cerrado of Amapá, its conservation status, and the main threats to the conservation of this Amazonian savanna. To secure the future of these unique and imperilled habitats, we suggest urgent expansion of protected areas, as well as measures that would promote less-damaging land uses to support the local population.

“…The state is bordered by northern Pará State to the west and French Guiana to the northwest, where the ecology of the disease has been studied more extensively [ 16 , 33 , 39 , 43 , 54 , 55 ]. There are only a few studies on the phlebotomines associated with ACL transmission in AP [ 5 , 15 , 17 , 18 , 46 , 58 ]. The aim of the present survey of the Serra do Navio phlebotomine population is in part to fill this gap by assessing putative transmission cycles in this Brazilian region of the Guiana Shield.…”

NaturalLeishmania(Viannia) infections of phlebotomines (Diptera: Psychodidae) indicate classical and alternative transmission cycles of American cutaneous leishmaniasis in the Guiana Shield, Brazil

From 1996 to 1999 multi-trapping methods (Center of Diseases Control, CDC) light traps, light-baited Shannon traps, and aspiration on tree bases) were used to study the phlebotomine fauna of the “Serra do Navio” region of the Brazilian State of Amapá, which is part of the Guiana Shield. Fifty-three species were identified among 8,685 captured individuals. The following species, associated with the transmission of American cutaneous leishmaniasis in Amazonian Brazil, were captured: Nyssomyia umbratilis (3,388), Psychodopygus squamiventris maripaensis (995), Ny. anduzei (550), Trichophoromyia ubiquitalis (400), Ny. whitmani (291), Ps. paraensis (116), and Bichromomyia flaviscutellata (50). Flagellate infections were detected in 45 flies. Of the 19 parasites isolated in vitro, 15 were Leishmania (Viannia) guyanensis (13 in Ny. umbratilis, 1 in Ny. whitmani, 1 in Ny. anduzei) and three were L. (V.) naiffi (2 in Ps. s. maripaensis, 1 in Ny. anduzei). The results indicate the participation of three phlebotomine species in the transmission of L. (V.) guyanensis and two species in that of L. (V.) naiffi, and show that the same phlebotomine species is involved in the transmission of different Leishmania (Viannia) species in the Guianan/Amazon region. A review of the literature together with the results of the present study, and other published and unpublished results, indicate that eight phlebotomine species potentially participate in the transmission of Leishmania (Viannia) naiffi in Amazonia.
