“…The positivity of animals observed here was higher than those obtained in epidemiological surveys carried out in other states, such as Bahia (Rodrigues et al 2020 ), Mato Grosso (Carvalho et al 2020 ), Minas Gerais (Castro-Júnior et al 2014 ), and São Paulo (Julião et al 2007 ). These results may be related to the diversity of biological samples and laboratory tests used in our study, which may allow an increase in the rates of sensitivity for the LC diagnosis (Sassaki et al 2011 ; Braz et al 2016 ).…”

Canine leishmaniasis (CanL) is a zoonosis caused by protozoa of the genus Leishmania and remains an important public health concern in tropical areas. In Brazil, domestic dogs are considered the most relevant reservoir of the parasite and one of the main targets of the disease control actions. Considering this, we aimed herein to evaluate the CanL infection in different canine groups and distribution of cases in the state of Sergipe, an endemic region in Northeastern Brazil. The evaluated 467 animals were classified into four groups: hunting ( n = 50), company ( n = 64), guard ( n = 140), and wandering ( n = 213). Samples (blood, bone marrow, conjunctival swab, and lymph node aspirate) were collected from animals in nine municipalities of Sergipe. First, all animals were submitted to general and ophthalmic clinical examination. Next, they were tested serologically by TR-DPP®, and for the presence of Leishmania , amastigotes in samples of bone marrow, conjunctival swab, and lymph node aspirate were diagnosed by PCR and parasitological techniques. It was observed that 34.69% (162) of the evaluated dogs were seropositive. The highest rates of positivity were found in hunting 54% (27/50; OR = 3.52; p -value = 0.001) and guard dogs 42.14% (59/140; OR = 2.18; p -value = 0.01). Otherwise, the highest percentage of symptomatic dogs was observed in wandering animals (85%; OR = 9.63; p -value < 0.0001). The distribution of case analysis showed that the highest positivity rates occurred in inland municipalities situated in arid regions. Taken together, our data demonstrate that hunting and guard dogs are among the animals most exposed and affected by clinical manifestations of CanL, mainly in the inland municipalities of Sergipe State.
