Occurrence of anti-Toxoplasma gondii antibodies and parasite DNA in backyard chicken breeding in Northeast, Brazil

Abstract: The aim of the present study was to investigate the occurrence of anti-Toxoplasma gondii antibodies and parasite DNA in backyard chickens bred in the metropolitan area of Recife, Brazil. In total, 212 serum samples were collected from 16 properties, and 12 backyard chickens were collected in the six sanitary districts of Recife. An indirect immunofluorescence assay (IFA) was used to investigate the occurrence of anti-Toxoplasma gondii antibodies. Polymerase chain reaction (PCR) was used to detect T. gondii DNA… Show more

“…The present study was developed in the mountainous region of the state (Venda Nova do Imigrante) for which no previous data on avian toxoplasmosis were available. In Venda Nova do Imigrante, 38% of the evaluated birds exhibited specific antibodies against T. gondii, our results were similar compared to results from backyard chickens in the metropolitan area of Recife (FERNANDES et al, 2016) and in the semiarid region of the state of Pernambuco (SÁ et al, 2017). Venda Nova do Imigrante also has a high prevalence of ocular toxoplasmosis, with 11.27% positive cases (ABREU et al, 1998), and is likely a favourable site for the presence and transmission of the parasite, as the mean prevalence of ocular toxoplasmosis in Brazil is 1.6% (ZANETTI & PLETSCH, 2007).…”

“…[16,17]. In the northeast region of Brazil, studies conducted with backyard chickens have described a prevalence of T. gondii up 40.56% by means the IFAT, and 94.8% of studied farm with at least one positive animal [18,19], similar to our results, where 36% of animals and 100% of farms were considered positive.…”

“…A presença de aves aumentou o risco de infecção por T. gondii em 2,49 vezes, onde a criação desses animais possa ser um atrativo para que gatos errantes adentrem as propriedades em busca de alimento contaminando, assim, as instalações. Fernandes et al (2016) encontraram alta ocorrência de aves soropositivas (40,6%) em criadouros da região metropolitana de Recife, onde nesses havia a presença de gatos, possíveis responsáveis pela contaminação do ambiente. A não observação da relação da presença de caninos e a infecção por Neospora caninum pode se dar devido a importância da transmissão vertical tanto em fêmeas infectadas antes e/ou durante a gestação (Syed-Hussain et al 2015).…”
