The pig population also becomes infected by this pathogen, and undercooked or raw meat is an important source of infection for humans. The aims of the present study were to evaluate the rate of exposure of pigs to T. gondii in the municipality of Mossor\u00f3, Rio Grande do Norte and seek to identify associations with possible risk factors. Blood samples were collected from 412 pigs and were analyzed using the immunofluorescence assay. Among these 412 serum samples, 40.7% were seropositive for T. gondii. The IgG antibody titers were 64 (56 specimens), 128 (32), 256 (37), 512 (23), 1024 (14), 2048 (5) and 4046 (1). Seropositivity for T. gondii was found to be related (p-value &lt; 0.05) to the following factors: female gender, semi-confined rearing system, use of well water, dewormed animals, presence of cats, goats, sheep, mice and vultures on the farm and carcasses left on the ground. In contrast, seropositivity was not related (p-value &lt; 0.05) to the age of the pigs, type of facility or feeding with human food remains. Preventive measures need to be adopted on the farms studied here, with the aim of decreasing the animals\u2019 intake of sporulated oocysts.<\/jats:p>","DOI":"10.1590\/s1984-29612019036","type":"journal-article","created":{"date-parts":[[2019,6,5]],"date-time":"2019-06-05T19:36:41Z","timestamp":1559763401000},"page":"508-513","source":"Crossref","is-referenced-by-count":8,"title":["Frequency of antibodies and risk factors associated with Toxoplasma gondii infection in backyard pig production in the city of Mossor\u00f3, state of Rio Grande do Norte, Brazil"],"prefix":"10.1590","volume":"28","author":[{"given":"Isabela Maria Campanelli dos","family":"Santos","sequence":"first","affiliation":[{"name":"Universidade Estadual J\u00falio de Mesquita Filho, Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexandro Iris","family":"Leite","sequence":"additional","affiliation":[{"name":"Universidade Federal Rural do Semi-\u00c1rido, Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Eduarda Chiaradia","family":"Furquim","sequence":"additional","affiliation":[{"name":"Universidade Estadual J\u00falio de Mesquita Filho, Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Diego Carlos de Souza","family":"Zanatto","sequence":"additional","affiliation":[{"name":"Universidade Estadual J\u00falio de Mesquita Filho, Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Simone de Jesus","family":"Fernandes","sequence":"additional","affiliation":[{"name":"Universidade Estadual J\u00falio de Mesquita Filho, Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Glaucenyra Cec\u00edlia Pinheiro da","family":"Silva","sequence":"additional","affiliation":[{"name":"Universidade Estadual J\u00falio de Mesquita Filho, Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paulo Henrique","family":"Sampaio","sequence":"additional","affiliation":[{"name":"Universidade Estadual J\u00falio de Mesquita Filho, Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rosangela Zacarias","family":"Machado","sequence":"additional","affiliation":[{"name":"Universidade Estadual J\u00falio de Mesquita Filho, Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1713-5222","authenticated-orcid":false,"given":"Marcos Rog\u00e9rio","family":"Andr\u00e9","sequence":"additional","affiliation":[{"name":"Universidade Estadual J\u00falio de Mesquita Filho, Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","published-online":{"date-parts":[[2019,7]]},"reference":[{"issue":"2","key":"ref1","doi-asserted-by":"crossref","first-page":"389","DOI":"10.1007\/s11250-010-9704-1","article-title":"Molecular survey of Toxoplasma infection in sheep and goat from Fars province, Southern Iran","volume":"43","author":"Asgari Q","year":"2011","journal-title":"Trop Anim Health Prod"},{"issue":"2","key":"ref2","doi-asserted-by":"crossref","first-page":"80","DOI":"10.1590\/S1984-29612010000200002","article-title":"Prevalence of anti-Toxoplasma gondii and anti-Neospora caninum antibodies in swine from Northeastern Brazil","volume":"19","author":"Azevedo SS","year":"2010","journal-title":"Rev Bras Parasitol Vet"},{"issue":"3","key":"ref3","first-page":"78","article-title":"Detection anti-Toxoplasma gondii antibodies in swines bred and abated in the Bahia State, Brazil","volume":"18","author":"Bezerra RA","year":"2009","journal-title":"Rev Bras Parasitol Vet"},{"issue":"3","key":"ref4","doi-asserted-by":"crossref","first-page":"186","DOI":"10.4322\/rbcv.2014.296","article-title":"Estudo soroepidemiol\u00f3gico da infec\u00e7\u00e3o por Toxoplasma gondii em su\u00ednos e frangos, para abate, em regi\u00e3o rural do Rio de Janeiro","volume":"13","author":"Bonna ICF","year":"2006","journal-title":"R Bras Ci Vet"},{"key":"ref5","first-page":"117","article-title":"Improved technique of indirect immunofluorescence for serological diagnosis of toxoplasmosis","volume":"6","author":"Camargo ME","year":"1964","journal-title":"Rev Inst Med Trop S\u00e3o Paulo"},{"issue":"4","key":"ref6","doi-asserted-by":"crossref","first-page":"863","DOI":"10.1645\/GE-830R.1","article-title":"Seroprevalence of Toxoplasma gondii antibodies in cats and pigs from rural Western Amazon, Brazil","volume":"92","author":"Cavalcante GT","year":"2006","journal-title":"J Parasitol"},{"issue":"4","key":"ref7","first-page":"209","article-title":"Toxoplasma gondii: indirect immunofluorescence diagnosis in swine in the State of S\u00e3o Paulo, Brazil","volume":"45","author":"Corr\u00eaa FM","year":"1978","journal-title":"Arq Inst Biol (Sao Paulo)"},{"issue":"2-4","key":"ref8","doi-asserted-by":"crossref","first-page":"89","DOI":"10.1016\/j.vetpar.2009.05.018","article-title":"Toxoplasmosis in pigs -
