Ocorrência de anticorpos contra Leishmania spp., Neospora caninum E Toxoplasma gondii em soros de cães atendidos no Hospital Veterinário da Universidade Estadual de Londrina-Pr

Abstract

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.

Zoonosis in dogs and cats attended by the Birth Control Project: Toxoplasma gondii, Leishmania spp. and Leptospira spp., serodiagnosis and epidemiology

“…IgG antibodies are shown in Table 4. Zulpo et al (2012) with dogs that were patients at the UEL VH, showed that 50.9% (57/112) were positive by IFA. The 20.6% prevalence found in this study is generally lower than reported by other studies in Paraná.…”

“…It has an average annual temperature above 21°C and an estimated human population of 506,701 (IBGE, 2011). There are an estimated 127,677 dogs in the city (ZULPO et al, 2012).…”

Estudo epidemiológico e avaliação de fatores de risco da infecção por Toxoplasma gondii e achados clinico-patológicos da infecção aguda em cães admitidos em um Hospital Escola Veterinário

“…Foram considerados positivos aqueles que reagiram em diluição a partir de 16; as amostras consideradas positivas passaram por sucessivas diluições na razão dois com objetivo de obter o título final. Títulos de 16, 32, 64, 128, 256 e 512 foram considerados títulos de contato (exposição prévia) e títulos iguais ou maiores que 1024 foram considerados títulos de infecção aguda (Zulpo et al 2012).…”

Leishmaniasis in dogs from recycling centers and from a neighborhood with adjacent forest in an urban area of Londrina, Paraná, Brazil

“…seroepidemiological studies in northern Paraná have shown prevalence to vary between 1.2% and 45.4% from 2007 to 2015 among dogs in urban environments. 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.…”
