“…The frequency of antibodies against T. gondii was similar to that reported by Braga et al (2012) in São Luís-MA (50.5%; 101/200) and Feitosa et al (2014) in Patos-PA (43.8%; 88/201). Such results may be attributed to the environmental similarities between Araguaína and São Luís.…”

Toxoplasma gondii and Neospora spp. are protozoa that have a significant impact on animal health due to the diseases they cause in domestic and wild animals. The aim of the present study was to investigate the presence of antibodies against T. gondii and Neospora spp. in cats from northern Brazil. Serum samples were collected from 180 cats in the municipality of Araguaína, Tocantins and used to evaluate the presence of anti-T. gondii and anti-Neospora spp. antibodies using the indirect fluorescent antibody test, with a cutoff of 1:64 and 1:25, respectively. The association between infection and individual animal characteristics (age, sex, origin, breed, and clinical signs) was tested using univariate analysis, followed by multivariate logistic regression. We found that 48.3% (87/180) of the animals had anti-T. gondii (95% CI: 40.8%–55.90%) and 3.9% (7/180) had anti-Neospora spp. (95% CI: 1.6%–7.8%) antibodies. There was no association between age, sex, breed origin, clinical signs, and seropositivity for T. gondii. Cats of defined breeds were more likely to be infected by Neospora spp. (OR = 10.7). Therefore, we found a high rate of seropositivity for T. gondii and a high rate of occurrence of Neospora infections in cats from the Araguaína region. The exposure of the feline population to the studied coccidia indicates the need to monitor the feline population for these infections and underscores the importance of effective sanitary measures against such pathogens.

“…The results found in Patos, in the state of Paraíba, can be attributed to the lowest established cutoff (1:16), which favors greater sensitivity of the technique. However, such samples were obtained from regions with unfavorable environmental conditions (semi-arid) (Feitosa et al, 2014).…”

“…The results obtained in the present study confirm the scope of distribution of the agent in Brazil. They also indirectly demonstrate that the soil is intensely contaminated with T. gondii oocysts, given that there is high seroprevalence of anti-T. gondii antibodies in cats in the semiarid region of northeastern Brazil, as described by Feitosa et al (2014). In the present study, viable T. gondii was isolated through bioassays in mice from the tissues of 29/63 seropositive sheep (47.5%).…”

Seroprevalence and isolation of Toxoplasma gondii in sheep intended for human consumption in Paraíba, northeastern Brazil

Toxoplasma gondii is a zoonotic parasite capable of infecting almost all warm-blooded animals. Currently, studies assessing the viability of cysts present in sheep meat are still scarce, especially in the northeastern region of Brazil. Therefore, the aim of this study was to evaluate the seroprevalence of anti-Toxoplasma gondii antibodies, isolate the parasite from tissue samples, and determine factors associated with infection of sheep intended for human consumption in the state of Paraíba, northeastern Brazil. Serum samples from 205 sheep slaughtered in Paraíba were tested using the indirect fluorescence antibody test (IFAT ≥ 64) for the presence of anti-T. gondii antibodies. Among the animals sampled, 30.7% (63/205) were seropositive, with antibody titers ranging from 1:64 to 1:16384. Sixty-one bioassays were performed in mice, and an isolation rate of 47.5% (29/61) was obtained. The infection was lethal to at least one infected mouse in 24.1% (7/29) of the bioassays. The mean length of survival of infected mice was 36.4 days. Females (OR = 3.183; CI = [1.452-6.976]), extensive breeding system (OR = 2.612; CI = [1.120-6.094]), and purebred animals (OR = 2.157; CI = [1.009-4.612]) were considered to be factors associated with infection. These results revealed that the prevalence of anti-T. gondii antibodies and the percentage of viable cysts recovered from sheep destined for human consumption in Paraíba, northeastern Brazil, were high.

“…The overall prevalence of seroreagent cats from the Brazilian semi-arid for T. gondii was 43.8%. We found a prevalence of 47.7% in domiciled cats and 36.2% in stray cats [ 30 ]. The incidence of oocyst shedding in the cat population studied was significantly higher than expected and higher than found in most cat population worldwide [ 31 ].…”

Aim:The aim of this research was to determine the copro-prevalence of Toxoplasma gondii using polymerase chain reaction (PCR) with repetitive 529 bp gene and to construct the phylogenetic tree of Toxoplasma oocyst from pet cats in Yogyakarta.Materials and Methods:9 of 132 pet cat samples which serologically positive for Toxoplasma were used in this research. To determine the copro-prevalence of T. gondii in pet cat, 10 g of feces samples taken from practitioners and household cats in Yogyakarta were used in the PCR method utilizing repetitive 529 bp gene sequences.Results:The result shows that copro-prevalence by PCR using repetitive 529 bp gene was 33.3% (3/9). The phylogenetic tree of Toxoplasma grouped into two clades, which clade 1 consists of Toxoplasma isolates collected from pet cats in Yogyakarta Indonesia and T. gondii isolates from China and in clade 2 consist of the T. gondii isolates from India.Conclusion:Copro-prevalence of T. gondii in pet cats in Yogyakarta by means of PCR using repetitive 529 bp gene is around 33.3%.
