“…Our occurrence data corroborates with similar studies performed in other Brazilian states such as Pará (50.0%; Freitas et al 2009) and São Paulo (48.0%; Villalobos et al 2011). However, the occurrence of toxoplasmosis in pigs found in this study was higher than those observed in previous studies: 36.2% in Paraíba (Azevedo et al 2010); 26.9% in Alagoas (Valença et al 2011); 18.2% in Bahia (Bezerra et al 2009); 12.8% in Mato Grosso (Muraro et al 2010); 12.6% in Paraná (Santos et al 2015) and 12.5% in Pernambuco (Fernandes et al 2012).…”

The Triângulo Mineiro region from Minas Gerais state, is an important meat-exporting region of Brazil and data about Toxoplasma gondii infection in pigs raised and slaughtered in this area are scarce. Therefore, the aim of this study was to evaluate the occurrence of T. gondii in swine and establish the risk factors associated with the infection. Samples were collected from 600 pigs raised under intensive system in farms located at three different counties (Carmo do Paranaíba, Patrocínio and Perdizes). The samples were submitted to indirect hemagglutination antibody test with dilution of 1:32 and to indirect immunofluorescence antibody test with a cutoff of 1:64. The occurrence of positive pig was 3.3% (n=20) and 51.8% (n=311) respectively. A significant difference was observed between toxoplasmatic infection and factors such as lineage, animal origin, size of the farm, collective raising with others species, presence of rodents and type of water offered (p≤0.05). There was no difference between gender and the farm goals. The results demonstrated an occurrence of anti-T. gondii antibodies higher than expected for intensive pig raising system on the studied area, which could indicate a possible sanitary management problem on the studied proprieties. Improvements on the raising techniques are necessary to reduce T. gondii infection sources.

“…Blood samples were collected and the seraum obtained was used to detect IgG antibodies against T. gondii by ELISA, as described by Silva et al, (1997 (PERDONCINI et al, 2010); 25.5% in Paraná (MILLAR et al, 2008) and 50% in Belém (FREITAS et al, 2009). Animals tested positive for T. gondii were detected in all the analyzed cities.…”

This study is aimed to assess the prevalence and risk factors associated with T. gondii infection in pigs. We evaluated 143 pigs, in 10 randomly-chosen farms located in Southern Piauí. The pig's blood serum was analyzed through ELISA in detection of anti-T. gondii antibodies. A seroprevalence of 25.5% was observed in the pigs that reacted against T. gondii antigens. The data from the records demonstrated an association with some factors such as: age, diet, type of management, breed and presence of cats in the farms with a prevalence of T. gondii. With the exception of sex, all others features represent risk factors for T. gondii infection. Furthermore, our data contributed to the understanding of the T. gondii seroprevalence in pig farms located in Southern Piauí.

“…Slaughterhouse without inspection may receive animals from dubious origin which could had higher prevalence of diseases due to poor hygiene conditions, which was not observed in the present study. Such data is difficult to compare since most of the studies deal only with pigs from abattoir with inspection (Carletti et al, 2005;Feitosa et al, 2014), although in Pará state previous report show 50% prevalence from animals slaughtered without inspection (Freitas et al, 2009). T. gondii and N. caninum infection were associated with the presence of its respective definitive host in the farms (Dubey, 2009;Gui et al, 2020).…”

“…Toxoplasma gondii is an intracellular protozoan that is distributed worldwide and is capable of infecting birds and mammals, including humans, with an estimated global seroprevalence of 19% (95% confidence interval [CI]: 17-22%) in pigs (Foroutan et al, 2019). In the Amazon region, serological studies have already demonstrated the prevalence of T. gondii in wild animals (Minervino et al, 2010;Soares et al, 2011;Vitaliano et al, 2015) including primates (Minervino et al, 2017), dogs (Valadas et al, 2010;Minervino et al, 2012), horses (Moreira et al, 2019) and pigs (Cavalcante et al, 2006;Freitas et al, 2009;Sousa et al, 2014). To our best knowledge, there is only one report on the occurrence of T. gondii antibodies in pigs in Pará State, which was limited to the municipality of Belém (Freitas et al, 2009), and reported that 50% (55/110) of the tested animals were seropositive.…”

We investigated the occurrence of Toxoplasma gondii and Neospora caninum antibodies in pigs raised in the Northeast of Pará, Brazil. At Study I, convenience sampled 151 pigs at two slaughterhouses, with and without state inspection; and Study II, which assessed 159 pigs with probabilistic sampling from nine pig farms. Serological analysis was performed using indirect fluorescent antibody test for T. gondii and N. caninum with a cutoff of 64 and 50, respectively. Overall, 6.77% pigs were seropositive for T. gondii and 5.16% for N. caninum. In Study I, pigs slaughtered with and without state inspection presented similar occurrence for both coccidia (p>0.05). Study II found an association between N. caninum seropositivity and sludge discarded into the soil, feeding pigs with animal-based protein, subsistence system, and absence of nipple drinkers. No association was found for T. gondii. Pigs from Pará are a potential source of T. gondii infection to humans. To our best knowledge, this is the first study to report anti-N. caninum antibodies in the serum of pigs in Pará State, Brazilian Amazon.
