“…There are few reports about the occurrence of N. caninum in cats. In this study, we found a seroprevalence to N. caninum of 22.5%, which is similar to previous reports in cats in the states of São Paulo (24.5%) and Maranhão in Brazil (27%) (BRESCIANI et al, 2007;BRAGA et al, 2012), and in Italy (24.8%) (FERROGLIO et al, 2005), but higher than that found by Dubey et al (2002) among cats sampled in the cities of São Paulo and Guarulhos, Brazil (11.9%). The possibility of crossreactions between T. gondii and N. caninum are remote, because cross-reactivity is observed only when soluble antigens are used, while surface antigens such as those used in IFA usually do not cause cross-reactions (DUBEY et al, 1996;HIGA et al, 2000).…”

“…The gender of cat was not a factor that could be correlated with N. caninum (p>0.05) infection, as also reported by other authors (FERROGLIO et al, 2005;BRESCIANI et al, 2007). Although environmental conditions seem to be an important factor for neosporosis infection, owing to the higher probability of contact with reservoirs of infection and final hosts (HORNOK et al, 2008), the results of this study did not reveal a significant correlation between the area of activity and the probability of infection with N. caninum.…”

An investigation was made into the occurrence of antibodies to Toxoplasma gondii, Leishmania infantum and Neospora caninum in 151 domestic cats, based on the indirect fluorescent antibody test (IFAT). Serum samples were collected from 151 domestic cats (65 free-roaming and 86 domiciled cats; 55 males and 96 females) in Campo Grande, Mato Grosso do Sul, Brazil between January and April 2013. IgG antibodies to T. gondii, L. infantum and N. caninum were found, respectively, in 49 (32.5%), 34 (22.5%) and 10 (6.6%) sampled cats. A positive correlation was found between T. gondii and N. caninum, T. gondii and L. infantum, and N. caninum and L. infantum (p < 0.05) infections. Also, a significant interaction was identified between gender and area of activity on the probability of T. gondii (p = 0.0324) infection. However, no significant interaction was observed between gender and area of activity on infections by either N. caninum or L. infantum. This study showed that cats from an area endemic for visceral leishmaniasis in Brazil are exposed to three different protozoans, two of which are causal agents of important zoonosis.Keywords: Cats, Leishmania infantum, Neospora caninum, Toxoplasma gondii, serology, Brazil. ResumoO presente estudo teve como objetivo investigar a ocorrência de anticorpos anti-Toxoplasma gondii, Leishmania infantum e Neospora caninum, em 151 gatos, por meio da Reação de Imunofluorescência Indireta (RIFI). Entre os meses de janeiro e abril de 2013, amostras de soro foram coletadas de 151 gatos domésticos (65 gatos errantes e 86 gatos domiciliados; 55 machos e 96 fêmeas), de Campo Grande, Mato Grosso do Sul, Brasil. Anticorpos IgG anti-T. gondii, anti-L. infantum e anti-N. caninum foram encontrados em 49 (32,5%) , 34 (22,5%) e 10 (6,6%) gatos amostrados, respectivamente. Verificou-se uma associação estatisticamente significativa entre as infecções por T. gondii e N. caninum, T. gondii e L. infantum e N. caninum e Leishmania infantum (p < 0,05). Além disso, foi observada uma interação significativa entre sexo, área de atividade na probabilidade de infecção por T. gondii (p = 0,0324). No entanto, não foi observada interação significativa entre sexo e área de atividade nas infecções por N. caninum e L. infantum. Este estudo mostrou que os gatos de uma área endêmica brasileira para leishmaniose visceral são expostos a três diferentes protozoários, sendo dois deles importantes agentes zoonóticos.

“…The prevalence of antibodies against N. caninum found in the present study was similar than what was reported among cats in Araçatuba, state of São Paulo (cutoff > 1:16;BRESCIANI et al, 2007), and in Italy (cutoff > 1:80; FERROGLIO et al, 2005). On the other hand, it was higher than what was found by Dubey et al (2002) in Brazil (11.9%; cutoff > 1:40), and by Hornok et al (2008) in Hungary (0.6%; cutoff > 1:40).…”

“…Regarding economic importance in livestock, N. caninum is recognized as an important cause of abortion in cattle . Most likely because cats may only play a minor role in the epidemiology of N. caninum infection, there are only a few reports on naturally acquired seropositivity to N. caninum among cats (DUBEY et al, 2002;FERROGLIO et al, 2005;BRESCIANI et al, 2007;HORNOK et al, 2008). The present study aimed to investigate the frequency of anti-T. gondii and anti-N. caninum antibodies in cats with outdoor access in São Luís, Maranhão, Brazil.…”

Occurrence of anti-Toxoplasma gondii and anti-Neospora caninum antibodies in cats with outdoor access in São Luís, Maranhão, Brazil AbstractThe present study aimed to investigate the frequency of anti-Toxoplasma gondii and anti-Neospora caninum antibodies in cats with outdoor access in São Luís, Maranhão, Brazil. The presence of IgG anti-T. gondii and anti-N. caninum antibodies was tested using the Indirect Immunofluorescent Antibody Test (IFAT). IgG anti-T. gondii and anti-N. caninum antibodies were detected in 101 (50.5%) and 54 (27%) sampled cats, respectively. The titers of anti-T. gondii antibodies ranged from 40 (cut-off) to 2560. On the other hand, the titers of anti-N. caninum antibodies ranged from 25 (cut-off) to 400. Twenty-seven cats (13.5%) were shown to be seropositive for both parasites. Seventy-four cats (34%) were seropositive only for T. gondii. Twenty-two cats (11%) were seropositive only for N. caninum. The present study showed that cats with outdoor access in São Luís, Maranhão, are exposed to T. gondii and N. caninum.Keywords: Toxoplasma gondii, Neospora caninum, cats, serology. ResumoO presente estudo objetivou verificar a frequência de anticorpos anti-Toxoplasma gondii e anti-Neospora caninum em gatos com acesso à rua em São Luís, Maranhão, Brasil. A presença de anticorpos IgG anti-T. gondii e anti-N. caninum foi verificado pela Reação de Imunofluorescência Indireta (RIFI). Anticorpos IgG anti-T. gondii e anti-N. caninum foram detectados em 101 (50,5%) e 54 (27%) gatos amostrados, respectivamente. Os títulos de anticorpos anti-T. gondii variaram de 40 (ponto de corte) a 2560. Por outro lado, anticorpos anti-N. caninum variaram de 25 (ponto de corte) a 400. Vinte e sete gatos (13,5%) mostraram-se soropositivos para ambos os parasitas. Setenta e quatro gatos (34%) foram soropositivos somente para T. gondii. Vinte e dois gatos (11%) foram soropositivos somente para N. caninum. O presente estudo demonstrou que gatos com acesso à rua em São Luís, Maranhão, são expostos ao T. gondii e N. caninum.

“…This is the first serologic survey for N. caninum antibodies performed in cats in the Czech Republic and third report in Europe. N. caninum antibodies were found by IFAT with cut-off titre 40 in 0.6% of 330 cats from Hungary (Hornok et al 2008) and in 24.8% of 282 stray cats from Italy by latex-agglutination test (Ferroglio et al 2005). The same methods cELISA and/or IFAT were used also in Brazil; N. caninum antibodies were found in 25% of 400 (Bresciani et al 2007) and in none of 70 (Coelho et al 2011) cats, respectively.…”

Sera of 414 cats coming from different parts of the Czech Republic were tested for N. caninum antibodies. Sera samples were collected during years [2002][2003][2004][2005][2006][2007][2008][2009][2010][2011]. N. caninum antibodies were detected by a commercial competitive-inhibition enzyme-linked immunosorbent assay (cELISA) with cut off ≥30% inhibition. Samples positive in cELISA were confirmed by an indirect fluorescence antibody test (IFAT); titre ≥50 was considered positive. In total, 137 (33%) cats reacted positively in cELISA; N. caninum antibodies in IFAT were detected in 16 (3.86%) cats with titres 50 and 100. In 6 cats, positive for N. caninum antibodies, T. gondii antibodies were also detected by IFAT. It is the first report of N. caninum antibodies in domestic cats from the Czech Republic and third report in Europe.
