Resumen
Introduction: The aim of the present study was to investigate the occurrence
of Leishmania infantum in South American coatis inhabiting two forest
fragments in Campo Grande, Mato Grosso do Sul, Midwest region of Brazil,
an endemic area of human and canine visceral leishmaniasis (VL).
Material and methods: A total of 110 South American coatis were sampled in
the conservation unit “Parque Estadual do Prosa” (PEP) and in the residential
area “Vila da Base Aérea” (VBA) from March 2018 to April 2019. As a longitudinal
study that include up to six recaptures of the same individual, a total of 190
capture events were obtained. Blood, bone marrow and skin samples were
obtained for parasitological (axenic culture), serological (Enzyme Linked
Immunosorbent Assay – ELISA and Dual-path Platform immunoassay –
DPP® CVL) and molecular diagnostic assays (targeting kDNA for Leishmania
spp. and L. infantum; and HSP70 followed by sequence analysis).
Results: Seropositivity for L. infantum was found in 33 individuals, six in PEP and
27 in VBA. Furthermore, L. infantum was detected by molecular analysis in 16
individuals, seven from PEP and nine from VBA. We also isolated L. infantum
from bone marrow of one individual and detected a single positive skin sample
in molecular assay from other individual, both from VBA.
