Seroprevalence of Toxoplasma gondii, Neospora caninum, and Leishmania spp. in hunting dogs from Mato Grosso do Sul, Brazil

Abstract

Toxoplasmosis, neosporosis, and leishmaniasis are important diseases of worldwide distribution and can affect both pets and humans. Hunting dogs have been trained to hunt domestic and wild animals, which makes them more exposed to parasitic infections. The present study aimed to evaluate the seroprevalence of Toxoplasma gondii, Neospora caninum, and Leishmania spp. in hunting dogs from a rural area in Mato Grosso do Sul, Brazil. Serum samples were collected from 39 American Foxhound dogs, and the sex and age variables were recorded. Serum samples were subjected to an indirect fluorescent antibody test (IFAT) to detect antibodies. Seroprevalence was 35.9%, 15.4%, and 2.6% for Toxoplasma gondii, Neospora caninum e Leishmania spp., respectively. There was no statistical difference between genders for these diseases (P>0.05). Results demonstrated a circulation of these protozoa in hunting dogs in a rural area of the state of Mato Grosso do Sul, which can contribute to the epidemiology of these diseases.

Toxoplasma gondii and Neospora caninum in invasive wild boars (Sus scrofa) and hunting dogs from Brazil

“…Both studies were conducted in the states of Paraná and Goiás. Additionally, Caramalac et al (2021) observed seroprevalence rates of 35.9% for T. gondii and 15.4% for N. caninum in Mato Grosso do Sul. Furthermore, the seroprevalence of antibodies against both parasites in hunting dogs in this study exceeded rates reported in studies from other regions of the world: 19.6% for T. gondii using the latex agglutination test in Taiwan ( Fan et al, 1998 ); 15% for N. caninum and 24% for T. gondii using IFAT in Spain ( Machačová et al, 2016 ); 52.8% for T. gondii using the modified agglutination test in Spain and Africa ( Cano-Terriza et al, 2016 ); and a mean of 36.8% for T. gondii using ELISA and modified agglutination test in Algeria ( Bellatreche et al, 2022 ).…”

Toxoplasmose Ovina E Equina: Ocorrência De Anticorpos Em Animais Criados Em Centro De Pesquisa Na Região Do Pantanal Sul Mato-Grossense, Brasil

“…O Pantanal abriga uma rica fauna silvestre, que inclui cerca de 132 espécies de mamíferos, incluindo felídeos ameaçados de extinção como a onça pintada (Panthera onca) e a jaguatirica (Leopardus pardalis) (16,17). Estudos epidemiológicos demonstraram a infecção por T. gondii em diferentes espécies de animais domésticos criados na região do Pantanal, ressaltando a importância da adoção de medidas de controle na região que minimizem os impactos desta parasitose na saúde animal (18)(19)(20). Nesse bioma, encontra-se a Fazenda Nhumirim, campo experimental da Empresa Brasileira de Pesquisa Agropecuária (Embrapa) no Pantanal, onde são criados, em sistema extensivo e pastagens nativas, rebanhos de bovinos, equinos e ovinos.…”
