“…A frequência de animais positivos para N. caninum em Lavras, MG, ficou bem abaixo dos valores de 10,0, 8,3, 10,7, 8,4 e 26,5% observados em cães criados em áreas urbanas de municípios como São Paulo, SP (GENNARI et al, 2002), Monte Negro, RO (CÂNON-FRANCO et al, 2004), Uberlândia, MG (FERNANDES et al, 2004), Campina Grande, PB (AZEVEDO et al, 2005) e Campo Grande, MS (ANDREOTTI et al, 2006), respectivamente. Porém foi similar ao resultado de 3,7% relatado por Mineo et al (2001), quando testaram 163 cães com distúrbios neuromuscular, respiratório e/ou gastrintestinal examinados no Hospital Veterinário da Universidade Federal de Uberlândia, MG. Valores de soroprevalência em cães variando de 0,2 a 29,0% foram reportados por Dubey (1999).…”

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...

Uninfected dogs and those naturally infected with Leishmania chagasi exhibiting different clinical forms of disease were evaluated for the presence of anti-Neospora caninum and anti-Toxoplasma gondii antibodies. Blood samples were collected from 110 mongrel dogs. Sera were tested using the indirect fluorescent antibody test (IFAT), and the animals with visceral leishmaniasis (VL) (n=60) were classified clinically. Out of the 110 sera investigated, 5 (4.5%) were positive for N. caninum (IFAT≥50) and 36 (32.7%) for T. gondii (IFAT≥16). Anti-L. chagasi antibody titers in asymptomatic dogs (n=10) were found to be significantly lower (P<0.05) than those in oligosymptomatic ones (n=22), which were in turn significantly lower (P<0.05) than those in symptomatic ones (n=28). No association between Leishmania and N. caninum infections was observed. Among dogs infected with L. chagasi, a tendency (P=0.053) towards an association between the infection with T. gondii and the appearance of VL symptoms was observed, suggesting that the clinical manifestation of VL in dogs may enhance their susceptibility to T. gondii. The possible influence of the immunosuppressive status of canine leishmaniasis in the different clinical forms of the disease is discussed.
