“…The values of 38.3% reported for raccoons ( Procyon lotor ) [ 16 ] and of 24.5% reported for the European mouflon ( Ovis orientalis musimon ) [ 17 ] were relatively high compared to values from other European studies in these species. These authors took this as evidence of high environmental contamination with oocysts as, in addition to the presence of feral, stray, and pet cats ( Felis sylvestris domesticus ), the study region was located within the core distribution area of the wildcat in central Germany [ 16 , 17 ]. Beral et al [ 4 ] found a positive link between higher T. gondii antibody levels in wild boar ( Sus scrofa ) and the occurrence of wildcats in France.…”

First report on the sero-epidemiology ofToxoplasma gondiiinfection in German roe deer (Capreolus capreolus)

While the roe deer (Capreolus capeolus) is the most important game species in Germany and its venison is popular, there is limited knowledge about the prevalence of Toxoplasma gondii in this animal population in the country, and in wild ungulates in Germany generally. Between 2013 and 2015, we collected 295 blood samples from roe deer belonging to a central German population. Sera were analysed using a modified agglutination test (MAT, cut-off 1:20), and antibodies were detected in 86 of the 295 samples (29%). Seroprevalence values differed significantly between the different age classes, with antibodies more frequently observed in adults. In contrast, seroprevalence did not differ significantly between the sexes or collection years. Venison is frequently consumed raw or undercooked and may be a potential source of human infection with T. gondii.

“…Our study area is indeed located within the core distribution area of the wildcat in central Germany [ 14 ]. Altogether, 38.3% of raccoons ( Procyon lotor ) sampled in the same study area were recently shown with a MAT test to be serologically positive for the protozoan [ 12 ].…”

Seroprevalence ofToxoplasma gondiiin free-living European mouflon (Ovis orientalis musimon) hunted in central Germany

et al. 2018

Despite increasing consumption of mouflon (Ovis orientalis musimon) meat in Germany, there is currently no surveillance of Toxoplasma gondii infection in populations of these animals and generally little knowledge about the prevalence of this protozoan in German wild ungulates. Between 2011 and 2015, we collected 138 blood samples from a free-living mouflon population in central German and tested sera for the presence of T. gondii antibodies using a modified agglutination test (MAT, cut-off 1:20). Antibodies were detected in 31 of the 138 samples (22.46%). There was a significant difference in seroprevalence between the different age classes, with antibodies to T. gondii more frequent in adults. In contrast, there was no significant difference in seroprevalence depending on sex and year of sample collection. Game meat is frequently consumed as raw or undercooked meat and may therefore represent a potential source of human infection with T. gondii.

“…Infection by the parasite may cause cerebral and ocular damage and even death, especially in immunodeficient patients [8,18]. 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].…”

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

et al. 2020

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.
