“…The results found in the present study regarding the occurrence of T. gondii are close to those found by Dantas et al (2013) in Natal, Rio Grande do Norte, who observed that 11.5% of the dogs were seropositive; and by Dantas et al (2014) in Patos, Paraíba, who observed that 15.6% were seropositive. Both of those However, in an evaluation on dogs during a vaccination campaign in Campina Grande, Paraíba, Azevedo et al (2005) found a prevalence of 45.1% using the IFAT.…”

The aim of this study was to determine the occurrence of infections due to Toxoplasma gondii and Neospora caninum and corresponding risk factors among dogs attended at veterinary clinics in the city of João Pessoa, Paraíba, northeastern Brazil. Blood samples were collected from 384 dogs that were attended at 34 veterinary clinics between April 2015 and May 2016. These two agents were diagnosed through the indirect immunofluorescence reaction (IFAT). Among the 384 animals evaluated, 37 (9.6%) were positive for T. gondii, with titers ranging from 16 to 512. Six dogs (1.6%) were positive for N. caninum, with titers of 50 to 200. Access to the streets (OR = 4.60; 95% CI = 1.74-12.20) and environments close to forested areas (OR = 2.79; 95% CI = 1.32-5.93) were found to be risk factors for T. gondii infection. The dogs attended at veterinary clinics in João Pessoa are exposed to infections caused by T. gondii and N. caninum. Dog owners should avoid having access to the street or contact with forest environments.

“…These three zoonotics have global distribution and may infect a great variety of domestic and wild animals, as well as humans (DANTAS et al, 2014). Dogs living in the outskirts of urban areas, where hygiene, sanitation, and infrastructure are precarious, and interactions with other animal species are highly probable, are an at-risk population for several different diseases (GENOVEZ, 1996).…”

“…It is an important clinical disease in high-risk groups, mainly pregnant women and immune-deficient individuals (DANTAS et al, 2014). Infection can occur through the ingestion of contaminated food or water, or the ingestion of raw or undercooked meat containing cysts of the infective agent (ARAÚJO et al, 2011).…”

“…Infection can occur through the ingestion of contaminated food or water, or the ingestion of raw or undercooked meat containing cysts of the infective agent (ARAÚJO et al, 2011). Dogs play an important role in the epidemiology of this disease, since they are used as sentinels for toxoplasmosis (SILVA et al, 2009;DANTAS et al, 2014). Similar to that in humans, infection of dogs with Toxoplasma gondii is generally asymptomatic, and epidemiological surveys in dogs have shown that age, access to the street, and type of dwelling are related to higher infection rates (ARAÚJO et al, 2011).…”

Dogs can act as intermediary hosts, reservoirs, and sentinel animals for zoonotic diseases such as brucellosis, toxoplasmosis and leptospirosis, and human contact with domestic animals can spread these infections. These diseases are globally distributed, and are a uniquely severe health issue, since they can infect a great range of animals, including humans. The purpose of this work was to determine the prevalence of anti-Leptospira spp., anti-Brucella spp., and anti-Toxoplasma gondii antibodies in stray dogs. Blood samples were collected from 181 stray dogs and used for serological diagnosis. Of the analyzed samples, 36.46%, 16.57%, and 9.39% were positive for T. gondii, Leptospira spp., and B. canis. The results indicate that these zoonotic diseases are highly prevalent in stray dogs in the northwestern region of the state of Paraná. The high infection rates for these zoonotics in the canine population is an indication that the environment is contaminated with a variety of different microorganisms, exposing both humans and dogs to different sources of infection.

ResumoO contato do homem com alguns animais domésticos faz com que algumas zoonoses como brucelose, toxoplasmose e leptospirose, tornem-se infecções importantes e, com isso os cães atuam como hospedeiros intermediários, reservatórios e animais sentinelas para estas infecções. Essas enfermidades tem distribuição mundial, e é um grave problema de saúde pública, podendo infectar uma grande variedade de animais, entres os quais, se destacam o cão e o homem. O objetivo deste trabalho foi detectar a ocorrência de anticorpos contra Leptospira spp., Brucella spp. eToxoplasma gondii em cães

“…Fato semelhante foi também observado por Azevedo et al (2005), Langoni et al (2006), Lopes et al (2011) e Dantas et al (2014 em que as taxas relativas mais elevadas de infecção foram encontradas com o aumento da idade. A infecção pós-natal é uma das principais formas de transmissão da toxoplasmose, assumindo importância, em função da idade, para os animais adultos, visto que há risco maior de entrarem em contato com possíveis fontes de infecção e as mais variadas vias de transmissão (Dantas et al 2014).…”

RESUMO: Objetivou-se com este trabalho determinar a frequência de animais soropositivos para Leptospira spp., Toxoplasma gondii e Neospora caninum em cães do Estado da Paraíba, Nordeste do Brasil, bem como identificar fatores de risco. Foram amostrados 1.043 soros de cães procedentes de cinco centros urbanos considerados polos regionais: João Pessoa, Campina Grande, Patos, Sousa e Cajazeiras. Para o diagnóstico sorológico da infecção por Leptospira spp. foi utilizada a soroaglutinação microscópica (SAM) enquanto que para detecção de anticorpos anti-T. gondii e N. caninum empregou-se a reação de imunofluorescência indireta (RIFI). Noventa e sete cães apresentaram aglutininas anti-Leptospiraspp., resultando em frequência de 9,3% (IC 95% = 7,5-11,1%). Os sorovares de maior frequência foram Icterohaemorragiae (47,4%), Copenhageni (16,5%), Bratislava (11,3%), Canicola (10,3%) e Pomona (6,2%). Observou-se soropositividade de 22,1% (231/1.043; IC 95% = 19,6-24,7%) e 7,7% (80/1.043; IC 95% = 6,1-9,3%) para T. gondii e N. caninum, respectivamente. Idade >48 meses (OR=2,92), raça não definida (OR=1,94) e criação com acesso à rua (OR=1,57) foram apontados como fatores de risco para infecção por Leptospira spp. Para toxoplasmose, as categorias idade >48 meses (OR=1,74), alimentação com comida caseira (OR=2,24), alimentação com ração e comida caseira (OR=2,34) e contato com gatos (OR=1,57) foram consideradas fatores de risco, enquanto que a criação com acesso à rua (OR=2,62) foi fator de risco para N. caninum. Conclui-se que cães de cinco centros urbanos do Estado da Paraíba estão expostos às infecções por Leptospiraspp., T. gondii e N. caninum, evidenciadas pela detecção de anticorpos, bem como sugere-se melhor manejo alimentar, controle no acesso a ambientes externos e destino adequado das fezes de gatos.
