“…Recorded data showed that intermediate hosts of T. gondii and N. caninum become infected in two ways of vertical (transplacental) and horizontal (ingestion of oocysts shed in milk and meat) (Belluco et al, 2017;Boas et al, 2015;Donahoe et al, 2015;Dubey, 2003;Hussain et al, 2017;Jones & Dubey, 2012;Klauck et al, 2016;McCann et al, 2008;Oshiro et al, 2015). Thus, contaminated milk and dairy products (particularly traditional dairy products) play an imperative role in the distribution of T. gondii and N. caninum infections to human (Ayinmode, Akinseye, Schares, & Cadmus, 2017;Gos et al, 2017).…”

The current investigation was done to examine the prevalence of Toxoplasma gondii and Neospora caninum in raw milk and traditional dairy samples. Eight‐hundred and eighty samples were collected and subjected to DNA extraction and nested PCR for detection of T. gondii B1 and N. caninum Nc5 genes. Seventy out of 880 (7.95%) and 80 out of 880 (10%) samples were positive for T. gondii and N. caninum, respectively. Simultaneous prevalence of T. gondii and N. caninum in studied samples was 4.20%. Prevalence of T. gondii and N. caninum in raw milk and traditional dairy samples were 6% and 10.60% and 10.52% and 9.21%, respectively. Traditional cheese and butter (15.00%) had the highest prevalence of T. gondii. Raw bovine (24.00%) had the highest prevalence of N. caninum. Boost prevalence of parasites in samples revealed an important public health threat regarding the consumption of raw milk and traditional dairy. Practical applications Due to the high consumption rate of milk and dairy products, they should have a high microbial quality. Toxoplasma gondii and Neospora caninum are two closely related protozoa with considerable zoonotic importance regarding the consumption of raw milk and traditional dairy products. The current research represents that raw milk and traditional dairy samples may be the sources of T. gondii and N. caninum transmission into the human population.

“…El punto de corte fue el porcentaje de reactividad ≥40= ODm−ODCNeg ODCPos−ODCneg 100 considerando negativo a los menores o iguales al 40%, dudosos entre 40 y 50% y positivos a los mayores o iguales al 50%. Mientras que otros 224 sueros diferentes se analizaron por Inmunofluorescencia indirecta con el procedimiento descripto por Gos (2017) haciendo un total de 686 animales testados.

“…Discusión Se detectaron anticuerpos anti T. gondii ampliamente distribuidos en la provincia. El promedio de UPs positivas fue de 79,49%, el resultado alto y cercano al 100%, se condice a que la mayor parte de las explotaciones poseían al menos un animal positivo, este dato es concordante con la bibliografía consultada que esta resumida en la Tabla 2, donde su porcentaje varía entre 70 y 100% (Bacci et al, 2016;Djokic et al, 2014;Figliuolo et al, 2004;Gos et al, 2017;Lopes et al, 2010;Panadero et al, 2009;Rossi et al, 2011;Shuralev et al, 2018;Tzanidakis et al, 2012;Zhao et al, 2011).

RESUMEN. La toxoplasmosis, causada por Toxoplasma gondii, es una zoonosis que produce pérdidas reproductivas en rumiantes.Este trabajo caracterizó la presencia indirecta, a través de anticuerpos, de la enfermedad en caprinos de la provincia de Salta a través de una encuesta en 39 unidades productoras (UP). Se tomaron muestras biológicas para el diagnóstico de enfermedades en la que fue incluida toxoplasmosis. En un análisis el promedio provincial de UP con animales positivos fue del 79,49% y la seroprevalencia media de los hatos fue 19,09% con valores entre 2,8 y 78,13% siendo más frecuentes valores menores del 20%. Se detectaron UP positivas en toda la provincia con los siguientes promedios de UP con animales positivos: Chaco Salteño (CS)=84,62%, Quebradas Áridas (QA)=72,72%, Valles Templados (VT)=80,00%. La seroprevalencia en los hatos osciló entre CS=3,50-20,00%, QA=2,80-42,00% y VT=6,25-78,13%, encontrándose anticuerpos contra T. gondii presentes en todas ecorregiones evaluadas de la provincia de Salta. SUMMARY. Caprine toxoplasmosis in Salta province, Argentina. Toxoplasmosis, caused byToxoplasma gondii, is a zoonosis that causes reproductive losses in ruminants. This work characterised indirectly (by detecting antibodies) the disease presence in goats from Salta province through a survey in 39 production units (PU). Biological samples were taken for a disease screening in which toxoplasmosis was included. The provincial average of positives PU was 79.49% and the average herd serum prevalence was 19.09% with values ranging between 2.8 y 78.13%, being more frequent values smaller than 20%. Positive PU were detected in all the provinces with the following averages of PU with positives animals: Saltean Chaco (SC)= 84.62%, Arid Ravines (AR)= 72.72%, Temperate Valleys (TV) = 80.00%. The ranges of seroprevalence were: CS= 3.50-20.00%, QA= 2.80-42.00% and VT= 6.25-78.13%. Antibodies against T. gondii were found in all the ecoregions of Salta province included in our study.

“…Humans are mainly infected with T. gondii by ingesting uncooked meat and water contaminated by oocysts from the environment, or by vertical transmission [2,3,7]. In addition, T. gondii can also have a negative influence on animal growth, development and reproduction, and cause great economic loss to livestock husbandry [6]. Livestock become infected mainly by ingesting food and water contaminated with sporulated oocysts [12].…”

Seroprevalence of Toxoplasma gondii infection in sheep in Inner Mongolia Province, China

et al. 2020

View full text Add to dashboard Cite

Toxoplasma gondii is an important zoonotic parasite that can infect almost all warm-blooded animals, including humans, and infection may result in many adverse effects on animal husbandry production. Animal husbandry in Inner Mongolia is well developed, but data on T. gondii infection in sheep are lacking. In this study, we determined the seroprevalence and risk factors associated with the seroprevalence of T. gondii using an indirect enzyme-linked immunosorbent assay (ELISA) test. A total of 1853 serum samples were collected from 29 counties of Xilin Gol League (n = 624), Hohhot City (n = 225), Ordos City (n = 158), Wulanchabu City (n = 144), Bayan Nur City (n = 114) and Hulunbeir City (n = 588). The overall seroprevalence of T. gondii was 15.43%. Risk factor analysis showed that seroprevalence was higher in sheep ≥12 months of age (21.85%) than that in sheep <12 months of age (10.20%) (p < 0.01). Seroprevalence was higher in male sheep (18.76%) than females (12.80%) (p < 0.01). Barn-feeding sheep (23.13%) had higher prevalence than grazing sheep (10.94%) (p < 0.01). The seroprevalence was significantly different in different districts (p < 0.01). This study shows that sheep are exposed to T. gondii in Inner Mongolia, and provides a data reference for public health and disease control.
