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

Abstract: 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 Brazi… Show more

“…A total of 57 peer-reviewed published articles studying the prevalence of toxoplasmosis in animals slaughtered in Brazilian abattoirs were found ( Table S2 ) [ 9 , 10 , 11 , 12 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 ,…”

“…The infective potential of lamb meat in Brazil was assessed using bioassay, PCR and immunohistochemistry ( Table S6 ), with the positive proportion ranging from 0 [ 25 ] to 85% [ 26 ], evidencing this potential for foodborne transmission. Here also, avoiding extensive breeding systems where animals have outdoor access can contribute to the reduction in T. gondii infections in small ruminants [ 63 ].…”

“…Fourteen T. gondii isolates from slaughterhouses in seven cities from Paraíba State, were used, five from goats and nine from sheep. The isolates were obtained through mouse bioassays as previously described in detail by Silva et al (2021) and Batista et al (2022) . DNA was extracted from the brains of the infected mice using a commercial extraction kit (PureLink™ Genomic DNA Mini Kit, cat K182002-Invitrogen, Carlsbad, CA, USA) and stored at −20 °C until analysed.…”

“…A infecção por T. gondii traz prejuízos econômicos para a pecuária, além das implicações para a saúde pública, pois o consumo de carne ou leite infectado pode levar a transmissão zoonótica (DUBEY, 2010;SILVA et al, 2021;MAIA et al, 2021). Falhas na reprodução são prejudiciais ao desenvolvimento da criação de ovinos e a toxoplasmose é considerada uma das principais infecções que causam perdas reprodutivas nos rebanhos (SOUZA et al, 2014).…”
