“…The prevalence of T. gondii antibodies (50.5%) in the cats of the present study was higher than what was found in previous studies conducted in Brazil, in the states of Santa Catarina (DALLA ROSA et al, 2010); São Paulo (SOGORB et al, 1972;LUCAS et al, 1998;SILVA et al, 2002;MEIRELES et al, 2004;PENA et al, 2006;BRESCIANI et al, 2007); Rio Grande do Sul ); and Rio de Janeiro (GONÇALVES NETO et al, 2003). On the other hand, the prevalence found in our study was lower than what was found among cats in Paraná (GARCIA et al, 1999) and Rondônia (CAVALCANTE et al, 2006).…”

“…Diet and access to the outdoor environment have been incriminated as important factors for cat infection (LUCAS et al, 1998). In our study, the sampled cats had free access to the outdoor environment, and probably had the opportunity to hunt small prey, thus becoming more susceptible to infection by T. gondii than are cats that are exclusively kept indoors.…”

“…Lower titers may suggest latent infection (LUCAS et al, 1998). It is difficult to draw conclusions from interpreting a single serological test on cats and, therefore, paired serological tests are desirable.…”

“…On the other hand, Rattus norvegicus, a common synanthropic rat species, could be considered to be a difficult prey for cats. Moreover, garbage food is more available than birds in urban areas (LUCAS et al, 1998).…”

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.

“…The 24.7% prevalence of seropositivity of this study was higher than that observed in the city of Niterói/RJ, which was 19.5% (GONÇALVES NETTO et al, 2003), and in Curitiba/PR, which was 16.3% (CRUZ, 2007), and lower than the prevalences found in São Paulo, which were 27.8% and 23.6% (LUCAS et al, 1998(LUCAS et al, , 1999.…”

Blood samples were collected from 89 cats to assess the prevalence of IgG antibodies against Toxoplasma gondii by indirect immunofluorescence (IIF) and the possible risk factors associated with feline Toxoplasma gondii infection. An epidemiological questionnaire was developed and implemented for owners of domestic cats domiciled in Rio Branco, Acre. The results were statistically evaluated with the odds ratio and chi-square tests, considering the significance level of 5%. Of 89 animals' samples, 22 had antibodies against Toxoplasma gondii. Among the 22 reactive animals, 15 (68.19%) were female, 15 (68.19%) were less than one year old and 20 (90%) were cross breed. Concerning risk factors, there was no difference (p > 0.05) between the variables evaluated by the chi-square test. Moreover, 16 (72%) cats were fed a mixed diet, 20 (90%) of the cats had hunting habits, 18 (81%) had contact with animals of another species, 11 (50%) had access to the street, and 21 (95%) lived in homes that had areas of grass or dirt. In conclusion, the prevalence of anti-Toxoplasma gondii in domestic cats was 24.7%, and there were no significant risk factors for feline toxoplasmosis in the municipality of Rio Branco, Acre. Key words: Toxoplasmosis, feline, seroprevalence ResumoCom o objetivo de avaliar a ocorrência de anticorpos IgG contra Toxoplasma gondii por meio de Imunofluorescência Indireta (RIFI) e associar com os possíveis fatores de risco para a enfermidade, foram colhidas amostras de sangue da veia jugular de 89 gatos domiciliados, na cidade de Rio Branco, Acre após a realização de inquérito epidemiológico pautado nos principais fatores de risco para a presença de anticorpos. Os resultados encontrados foram avaliados estatisticamente com o teste de razão de chances (Odds ratio) e qui quadrado, considerando-se o nível de significância de 5%. 11 (50%) tinham livre acesso à rua e 21 (95%) habitavam casas que possuíam áreas de grama ou terra. Conclui-se que na cidade do Acre, Rio Branco, a prevalência de anticorpos (IgG) para anti-Toxoplasma gondii nos felinos domiciliados foi de 24,7%, e que os fatores de risco não foram significantes.

Antibodies to Neospora caninum and Toxoplasma gondii in domestic cats from Brazil

The occurrence of antibodies to Neospora caninum and Toxoplasma gondii was determined in 400 domestic cats (Siamese, Persian, and undetermined breeds) from the Municipality of Araçatuba, Sao Paulo, Brazil, through the indirect fluorescence antibody test (IFAT). Of the 400 cats, 100 were seropositive to T. gondii (25%, titer > or =64) and 98 to N. caninum (24.5%, titer > or =16). The rate of seropositive cats for T. gondii was correlated with age (chi(2)=35.7; p<0.001), with a higher number of infected animals at older ages. Of the 219 cats younger than 1-year-old, 13.2% were seropositive for T. gondii, while 39.2% were positive in the 181 older animals. The presence of N. caninum was also correlated with age (/(2)=8.8; p<0.01), with 18.7% (41/219) and 31.5% (57/181) of positive animals at ages below and above 12-month, respectively. An association between the occurrences of both protozoa in the felines was also observed (chi(2)=19.6; p<0.001).
