“…Surprisingly, to the best of our knowledge, this study was the first serosurvey on this dog population worldwide. Despite the outdoor and free-roaming habits of neighborhood dogs, which may increase their exposure to protozoan infections (AZEVEDO et al, 2005;COLLANTES-FERNÁNDEZ et al, 2008;MOURA et al, 2009;NAZIR et al, 2014), they presented in this study a low seroprevalence for T. gondii and N. caninum compared with literature results (MEIRELES et al, 2004;SEABRA et al, 2015;VALADAS et al, 2010), which may indicate that there was a situation of low environmental oocyst contamination (MEIRELES et al, 2004). Since dogs play a secondary role in the toxoplasmosis cycle, neighborhood dogs may be considered to be true environmental sentinels for T. gondii, particularly when sharing a contaminated urban environment and contaminated food and water (MEIRELES et al, 2004).…”

“…For dogs living in stray situation in Brazil, as neighborhood dogs, the seroprevalence for Leishmania spp. have been ranging from 0.0027% to 32.5% (FREHSE et al, 2010;SEABRA et al, 2015;TRONCARELLI et al, 2009;VALADAS et al, 2010), for T. gondii from 31.6% to 68.4% (MEIRELES et al, 2004;SEABRA et al, 2015;SOUZA et al, 2003;VALADAS et al, 2010), for T. cruzi from 2.0% to 4.0% (MORAIS et al, 2013;TRONCARELLI et al, 2009) and for N. caninum from 3.2% to 22.1% (FRIDLUND-PLUGGE et al, 2008;SEABRA et al, 2015;SOUSA et al, 2012;VALADAS et al, 2010).…”

“…Because of the outdoor and free-roaming habits of neighborhood dogs, these dogs may present greater exposure to environmental and vector-borne diseases such as Leishmania spp., Toxoplasma gondii, Trypanosoma cruzi and Neospora caninum (CABEZÓN et al, 2010;SEABRA et al, 2015;TENNEY et al, 2014).

Neighborhood dogs may act as reservoirs for several zoonotic protozoan infections, particularly in urban areas, thus constituting a potential public health threat. Accordingly, the aim of the present study was to evaluate the exposure of neighborhood dogs to four protozoan pathogens in public areas with high levels of human movement in Curitiba, southern Brazil. Blood samples from 26 neighborhood dogs were screened by means of the indirect immunofluorescent antibody test (IFAT) for Leishmania spp., Toxoplasma gondii, Trypanosoma cruzi and Neospora caninum, and a questionnaire was answered by the respective keeper. A total of 8/26 dogs (30.7%) seroreactive to T. gondii, 3/26 (11.5%) to N. caninum and 2/26 (7.7%) to both were identified. All the samples were seronegative for T. cruzi and Leishmania spp. Pathogen seroreactivity was not associated with the daily human movements or other epidemiological variables investigated (p > 0.05). In conclusion, the low seroprevalence for T. gondii and N. caninum indicated low environmental and food risk for animal infection and the seronegativity for Leishmania spp. and T. cruzi may reflect the absence of these pathogens in urban areas of Curitiba. Moreover, neighborhood dogs may be used as environmental sentinels for the presence of protozoan pathogens and their vectors.

“…may enhance the susceptibility of dogs to N. caninum infection (CRINGOLI et al, 2002). Serological surveys correlating N. caninum and Leishmania spp., had been conducted ANDREOTTI et al, 2006;GUIMARÃES et al, 2009;GRECA et al, 2010;VALADAS et al, 2010a;LOPES et al, 2011;PAULAN et al, 2013;SEABRA et al, 2015;CONSTANTINO et al, 2016). In dogs from endemic cities of visceral leishmaniosis such as Araçatuba, SP , Campo Grande, MS (ANDREOTTI et al, 2006), and Teresina, PI (LOPES et al, 2011), positive association was found (Table 3).…”

Neospora caninum is protozoan parasite with domestic and wild dogs, coyotes and grey wolves as the definitive hosts and many warm-blooded animals as intermediate hosts. It was cultivated and named in 1988. Neosporosis is a major disease of cattle and has no public health significance. Since 1990's N. caninum has emerged as a major cause of abortion in cattle worldwide, including in Brazil. N. caninum also causes clinical infections in several other animal species. Considerable progress has been made in understanding the biology of N. caninum and there are more than 200 papers on this subject from Brazil. However, most of the reports on neosporosis from Brazil are serological surveys. Overall, little is known of clinical neosporosis in Brazil, particularly cattle. The few reports pertain to sporadic cases of abortion with no information on epidemics or storms of abortion. The objective of the present review is to summarize all reports from Brazil and suggest topic for further research, including prevalence of N. caninum oocysts in soil or in canine feces, and determining if there are additional definitive hosts, other than the domestic dog. There is need for a national survey in cattle using defined parameters. Future researches should focus on molecular characterization of N. caninum strains, possibility of vaccine production and relationship between wildlife and livestock epidemiology.Keywords: Neospora caninum, neosporosis, domestic animals, wild animals, Brazil. ResumoNeospora caninum é um protozoário parasita que possui os canídeos domésticos e selvagens, coiotes e lobos cinzentos como hospedeiros definitivos e vários animais de sangue quente como hospedeiros intermediários. Foi cultivado e nomeado em 1988. A neosporose é uma das principais doenças em bovinos e não tem significância em saúde pública. Desde 1990, N. caninum tem emergido como uma das principais causas de aborto em bovinos em todo o mundo, inclusive no Brasil. N. caninum também causa infecções clínicas em várias outras espécies animais. Consideráveis avanços foram feitos na compreensão da biologia desse parasita e há mais de 200 trabalhos sobre o assunto no Brasil. No entanto, a maioria dos relatos de neosporose do Brasil são relacionados a sorologia. Em geral, pouco se sabe sobre a neosporose clínica no Brasil, particularmente em bovinos. Os poucos relatos referem-se a casos esporádicos de aborto sem informações sobre epidemias ou surtos de aborto. O objetivo da presente revisão é resumir todos os relatos sobre N. caninum no Brasil e sugerir tópicos para pesquisas futuras, incluindo a prevalência de oocistos de N. caninum no solo ou em fezes caninas e determinar se há hospedeiros definitivos adicionais, exceto o cão doméstico no país. Uma pesquisa nacional em bovinos usando parâmetros definidos seria de grande importância. Pesquisas futuras deveriam ser focadas na caracterização de cepas de N. caninum, possibilidade de produção de vacinas e a relação epidemiológica entre a vida selvagem e o gado.Palavras-chave: Neospora caninum, neospo...
