“…Leishmania braziliensis is the prevalent causative agent of American cutaneous leishmaniasis (ACL) in South America and occurs in every Brazilian state; autochthonous cases have been reported in the Vale do Ribeira, central, and northern regions of Paraná state (CASTRO et al, 2007). According to Dantas-Torres et al (2010), there is still speculation concerning the role of dogs as important ACL reservoirs; however there is no doubt that dogs are good sentinels for disease distribution and that the primary reservoirs are small wild rodents.…”

“…Nosso trabalho revelou que 11,6% dos cães avaliados apresentou anticorpos para Leishmania spp., demonstrando a presença do parasito na área do presente estudo. Contudo, no que diz respeito à leishmaniose tegumentar, ainda não está claro a importância do papel epidemiológico do cão (DANTAS-TORRES, 2007;CASTRO et al, 2007). Santos et al (2005) destacaram que a presença das formas clínica ou subclínica dessa doença na população canina associada à infecção humana sugere a participação dos cães como fonte de infecção na disseminação da doença.…”

The aim of this study was to detect the presence of IgG antibodies anti-Leishmania spp., Toxoplasma gondii and Neospora caninum in dogs from a Veterinary Hospital from Universidade Estadual de Londrina. Blood samples from 112 animals were obtained by jugular venipuncture to obtain sera. The samples were tested by indirect immunofluorescence to detect antibodies anti-Leishmania spp., anti-N. caninum and anti-T. gondii. Thirteen (11.61%), 25 (22.32%), and 57 (50.89%) samples were positive for Leishmania spp., N. caninum, and T. gondii, respectively. The co-presence of anti-Leishmania spp. and N. caninum was observed in 6 (5.36%), anti-Leishmania spp. and anti-T. gondii in 8 (14.7%), and anti-N. caninum and anti-T. gondii in 18 (16.07%) samples. The co-presence of anti-Leishmania spp., anti-N. caninum and anti-T. gondii was observed in 5 (4.46%) dogs. There was a higher prevalence of Leishmania in Toxoplasma and Neospora positive animals, however, these results were not statistically significant (range p = 0.052 p = 0.06). The dogs have an important role in the epidemiological cycle of these diseases, which are important in animal and public health. The northern state of Paraná is an endemic area for human cutaneous leishmaniasis, therefore, studies should be conducted to uncover the real role of dogs as reservoirs of Leishmania to humans in the state.

“…Zulpo et al (2012) and Caldart et al (2015) studied animals from Londrina and found 11.6% (13/112) and 1.2% (3/236) of seropositivity using IFAT method with 1:40 as a cutoff, respectively; the low prevalence of 1.2% found by the authors may be explained because this study population consisted of clinically healthy animals undergoing elective castration surgery. Pittner et al (2009) (CASTRO et al, 2007;PEREIRA, 2005, HOFFMANN et al, 2012. Several phlebotomine species are present in the same State, and the dominant vector species found infected is Nyssomyia whitmani (MEMBRIVE et al, 2004;OLIVEIRA et al, 2000) wich is involved in the transmission of L. (V.) braziliensis; however, L. (L.) amazonensis vectors have never been found in Paraná.…”

The leishmaniasis are a group of globally widespread parasitic diseases caused by a protozoa of the genus Leishmania, the state of Paraná accounts for 98% of leishmaniasis human cases in southern Brazil and the dogs might serve as a sentinel of the risk of infection to humans in a given area. The aim of this work was to study the epidemiology of leishmaniasis in dogs residents in two different environments, they are: recycling of solid waste centers (Group 1) and a neighborhood adjacent to a forest (Group 2), both in Londrina, Paraná State, Brazil and to determine epidemiological variables associated to infection in these different realities. Serum samples, randomly collected, from 61 dogs from Group 1 and from 74 dogs from Group 2 were submitted to Indirect Immunofluorescence Antibody Test (IFAT) to research for anti-Leishmania IgG antibodies. Of the 135 dogs analyzed, 13 animals (9.6%) were positive; nine (14.7%) in Group 1 and four (5.4%) in Group 2, the difference between the groups is not statistically significant. These results suggest the presence of the protozoan Leishmania spp. in both environments studied which indicate potential for infection in the human population. Key words: Environment. Leishmaniasis. Marginality. Risk factors. Seroprevalence. ResumoAs leishmanioses são um grupo de doenças parasitárias disseminadas por todo o mundo, causadas por protozoários do gênero Leishmania, o estado do Paraná é responsável por 98% dos casos de leishmaniose em humanos do Sul do Brasil e os cães podem servir como sentinelas para o risco de infecção em humanos em uma dada área. O objetivo desse trabalho foi estudar a epidemiologia da leishmaniose em cães residentes em dois diferentes ambientes, são eles: centros de reciclagem de resíduos sólidos (Grupo 1) e um bairro adjacente a uma floresta (Grupo 2) em Londrina/PR, Brasil e determiner variáveis epidemiológicas asociadas à infecção nessas diferentes realidades. Amostras de soro, randomicamente coletadas, de 61 cães do Grupo 1 e de 74 cães do Grupo 2 foram submetidos à Reação de Imunofluorescência Indireta (RIFI) para pesquisa de anticorpos IgG anti-Leishmania. Dos 135 cães analisados, 13 (9,6%) foram positivos; 9 (14,7%) no Grupo 1 e 4 (5,4%) no Grupo 2, a
