“…(Richomme et al 2009), antibodies to T. gondii were found in 23% (216/938) and 18% (26/148) of hunted wild boars, respectively. In our study, prevalence observed in wild boars (16.8%; 141/841) is similar to recent data from the Netherlands (24.4%; 237/973), Estonia (24%; 113/471) (Jokelainen et al 2015), Italy (14%; 56/400) and Portugal (21%; 20/97) (Opsteegh et al 2011, Ranucci et al 2013a, Coelho et al 2014). In the Czech Republic and in Poland, Račka et al (2015) and Witkowski et al (2015) found higher values, i.e.…”

Toxoplasma gondii (Nicolle et Manceaux, 1908) is an obligate intracellular, parasitic protozoan within the phylum Apicomplexa that causes toxoplasmosis in mammalian hosts (including humans) and birds. Since meat of wild boar, Sus scrofa (Linnaeus), has been demonstrated to be a potential source of human infection, a careful evaluation of the prevalence of infection with T. gondii in hunted animals is needed to protect public health. In the Var area in southeastern France, we performed a spatio-temporal survey in order to investigate the prevalence of IgG antibodies in wild boars shot by hunters in the Canjuers military camp during two subsequent hunting seasons. Of 841 wild boars screened, antibodies (IgG) to T. gondii (modified agglutination test, cut-off 1 : 6) were found in 141 (16.8%) muscle extract samples. A significant association (p < 0.001) was found between positivity and age, but not gender, and hunting districts. The results obtained indicate that consumption of raw or undercooked meat from wild boars carries an important risk of infection with T. gondii. Wild boars may be considered as a bioindicator of parasite circulation in this ecosystem.

“…Similar results were obtained in Spain (38.4%, MAT) [48], Italy (43.3%, ELISA) [32], Sweden (49.5%, ELISA) [49], and the Czech Republic (39.6%, ELISA) [9]. The percentage of seropositive wild boar was lower in several studies conducted in the Czech Republic (15.4% and 26.2%) [31,37], Spain (23.8%) [50] and Sweden (28.6%) [29], as well as in France (16.8% and 17.6%) [4,51], Switzerland (6.7%) [2], The Netherlands (24.4%) [39], Slovakia (8.1%) [3], Finland (33%) [52], Portugal (20.6%) [1], Denmark (27.7%) [53], Greece (5.2%) [25], Romania (16%) [54], Italy (14%) [55], Latvia (33.2%) [56] and Estonia (24%) [38].…”

“…A correlation was also noted between detection of the antibodies and parasite isolation [56], even though some authors believe this claim to be unsubstantiated [2]. Although the results of different studies provide information on the presence of T. gondii antibodies in wild boar, they should not be directly compared due to different methodology, lack of standardized research methods (different sensitivity, specificity and limiting thresholds), different types and number of tested samples, and methods of their collection, origin of the animals, as well as geographical [55,61] and climatic differences, and different degree of soil contamination with the oocysts.…”

Introduction and objective. Toxoplasmosis is an important zoonosis caused by a protozoan, Toxoplasma gondii. Raw or undercooked venison may be a source of infection in humans. The aim of the study was to determine the prevalence of T. gondii antibodies in wild boar from the Strzałowo Forest Division of the Warmia and Mazury Region of Poland. Materials and method. A total of 90 samples were collected from 50 wild boar: 40 from both tongue and diaphragm muscles, 4 from diaphragm muscles and six from tongue muscles. Samples were analyzed using the commercial PrioCHECK® Toxoplasma Ab porcine ELISA, according to the manufacturer's instructions. Results. T. gondii antibodies were detected in 24 of 50 (48%) tested animals. T. gondii antibodies were detected in 40 of 90 (44.4%) tested samples (21 of tongue muscles and 19 of diaphragm muscles). In the 40 wild boar that provided samples of meat juice from the tongue and diaphragm muscles, specific antibodies were more prevalent in the tongue (20 of 40 animals-50%) than in the diaphragm muscles (17 of 40 animals-42.5%). Conclusions. The study revealed a high percentage of wild boar seropositive to T. gondii. Muscle samples to obtain meat juice are easily available and simple to collect, even on the hunting grounds, which makes them suitable material for detecting T. gondii antibodies in wild boar. Wild boar are essential to T. gondii circulation in the environment, and raw or undercooked venison may be a source of human infections with this parasite.

“…In Italy, Neospora caninum and Toxoplasma gondii are widespread in wild animals such as wild boars (Ranucci et al 2013), wild rabbits (Zanet et al 2013) and hares (Abramo et al 1997). Gondim et al (2004) demonstrated a sylvatic transmission cycle of N. caninum between wild animals and canids.…”

Abstract:Hunting dogs have probably a higher level of exposure to Neospora caninum Dubey, Carpenter, Speer, Topper et Uggla, 1988 and Toxoplasma gondii Nicolle et Manceaux, 1908 than other canine populations for their different lifestyle. The aim of our survey was to determine the seroprevalence of N. caninum and T. gondii in hunting dogs from southern Italy and assess risk factors related to these protozoan infections. Blood samples were collected from 398 hunting dogs (19 different breeds, aged from 5 month to 14 years). The sera were screened by indirect fluorescence antibody test; a titre ≥ 50 was considered positive. Antibodies to N. caninum and T. gondii were detected in 59 (15%) dogs with titres from 50 to 3 200 and in 94 (24%) dogs with titres from 50 to 1 600, respectively, with co-infection in 25 (6%) dogs. Statistical difference (p ≤ 0.05) was found only for infection with T. gondii between two age groups: ≥ 2-4 years (16%) and ≥ 4-7 years (33%); other observed characteristics were without statistical significance. Our results suggest that the hunting dogs could play an important role in the transmission cycle of N. caninum between wild animals and livestock. This is the first detection of antibodies to T. gondii in hunting dogs in Italy.
