Clinical-epidemiological profile of dogs infected by with Leishmania infantum admitted
at the Veterinary Teaching Hospital of Universidade Federal Rural de Pernambuco.
Canine Visceral Leishmaniasis, Public Health, Zoonosis.
Visceral Leishmaniasis is a vector-borne parasitic disease caused by Protozoa of the
genus Leishmania, which are transmitted by different species of sandflies. This disease
is endemic in several regions of Brazil, and dogs are incriminated as the main reservoir
of infection in urban settings. Although there are no studies that describe the profile of
dogs with Visceral LeishmaniasisThe goal of this work was to evaluate the clinical-
epidemiological profile of dogs infected by with Leishmania infantum who were admitted
at the Veterinary Teaching Hospital of Universidade Federal Rural de Pernambuco.
During the study period, 130 dogs from of different canine breeds, ages and both sexes
were admitted, of which 100% had a parasitological diagnosis and sorological test
(DPP®/Biomanguinhos test) of Visceral Leishmaniasis. The analysis of the factors
associated to the positive diagnosis was evaluated according not only the breeds, ages,
sexes, clinical signs, but also the origin of dogs. in addition, it was evaluate the
effectiveness of parasitological (bone marrow biopsy, lymph node aspiration cytology
and skin cytology) and serological ( DPP) methods. Thus, to compare the variables
breed, age and sex, the correlation coefficients coefficients underwent Kruskal-Wallis
non-parametric test using the statistical software and G-Test for the other analyses.
Regarding the age-group distribution, 6,9% of the dogs were less than one year old;
44,62% were between one and three years; 26,16% were between three and six years;
15,38% were between seven and nine years and 6,9% were older than nine years. The
study was conducted in 12 municipalities of the Metropolitan Region of Recife and the
geographic distribution of positive dogs were 130 dogs, being 45,38% of the Paulista,
14,62% of the Recife, 6,92% of the Ilha de Itamaracá, Olinda and Jaboatão dos
Guararapes, and 19,24% of the other municipalities. Among the analyzed profiles,
mixed-breed dogs from the city of Paulista, aged 1 to 3 years old, male, symptomatic,
positive in DPP, bone marrow aspiration biopsy and lymph node aspiration cytology
showed a positive association with Canine disease. In conclusion, greater attention is
needed both in the physical examination and in the forms of prevention, in SRD dogs
from the city of Paulista, mixed-breed, adult and symptomatic, as they are animals with
an important epidemiological profile for having canine visceral leishmaniasis. In
addition, symptomatic animals deserve attention since only 1.54% were asymptomatic.
