Abstract
This study performed clinical, serological and
parasitological assessments in dogs from Vale do Rio Doce,
in Minas Gerais State, Brazil, a region considered as a
‘controlled endemic’ area for canine visceral leishmaniosis
(CVL). Nevertheless, there are signs that CVL in dogs may
be re-emerging as a programme to control the disease was
interrupted in the 1990s. The majority of the animals
examined presented various symptoms associated with
CVL. The enzyme-linked immunosorbent assay test indicated
13.7 and 12.4% of positivity of dogs from the urban
and rural areas, respectively. According to indirect immunofluorescence
assay test and TRALd tests, 18.2 and 42.2%
of dogs in the rural area were seropositive, respectively.
Parasitism in seropositive dogs was confirmed by in vitro
tissue culture. Sand flies of the genus Lutzomyia, which are
able to transmit both cutaneous and visceral leishmaniosis,
were found in the area. The results provide a strong
evidence of the re-emergence of CVL in this region.
