Soroprevalência e fatores associados à infecção por Toxoplasma gondii em caprinos de propriedades rurais do município de Mossoró, RN

Abstract

The municipality of Mossoró, RN, Northeastern Brazil, is featured on goat rearing. Toxoplasmosis is a zoonosis which is more pathogenic for goats when compared with other animals for slaughter. In this species, the protozoan is often responsible for reproductive problems and economic losses. In order to identify the seroprevalence and risk factors of toxoplasmosis in goats of farms in this municipality, serum samples from 338 animals (320 females and 18 males) of 15 production units were tested by enzyme immunoassay (ELI-SA). Of the 15 farms, 14 had animals positive for Toxoplasma gondii, and in these the total number of seropositive animals were 125 (123 females and 2 males), yielding a prevalence of 37.0%. There was a significant relationship (p<0.05) between prevalence and sex, and between the prevalence and breed of animals. The most important risk factors associated with T. gondii infection were: water supply with odds ratio (OR=2.635), containers for water animals located outside the premises of property (OR=3.121) and the exploitation of dairy type (OR=2.546). For the analysis of the avidity ELISA, was found females of reproductive age in the acute phase of infection.

Toxoplasma gondii infection in goats: serological, pathological, and clinical monitoring during gestation

“…We believe that transplacental transmission in our study is of exogenous type because during the experiment, it was possible to observe that cats of different ages had free access to the facilities, feed deposits, and drinking fountains. Cats are the definitive hosts of T. gondii (Dubey 2005 ) and are considered the main risk factor for toxoplasmosis in goats (Anderlini et al 2011 ; Nunes et al 2013 ; Liu et al 2015 ).…”

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

“…The prevalence of anti-T. gondii antibodies in sheep intended for human consumption is variable. In the state of Section Editor: Nawal Hijjawi Alagoas, northeastern Brazil, the seroprevalence of anti-T. gondii IgG antibodies in slaughtered sheep was found to be 14% (14/100), using the indirect fluorescence antibody test (IFAT) Nunes et al 2013). In Rondônia, northern Brazil, Maia et al (2020) detected the presence of antibodies against this protozoon in 52.4% (323/616) of the samples evaluated, using IFAT.…”

Occurrence of anti-Toxoplasma gondii antibody and evaluation of risk infection factors in goats raised in Sergipe state, Brazil

“…Goats are more susceptible to clinical toxoplasmosis when compared to other farm animals, causing economic losses in herds around the world due to reproductive disorders, such as abortions of mummified fetuses and births of weak puppies, which can be repeated in subsequent pregnancies (Nunes et al 2013, Silva et al 2015. The clinical signs are variable and unspecific for a definitive diagnosis of toxoplasmosis (Spósito Filha & Oliveira 2009).…”
