“…Several factors can potentially modify the risk of T. gondii infection in pigs, such as the presence of cats on farms, rodent control, age of the animals, size and type of the herd, outdoor access, the carcass disposal, and feeding of unprocessed animal products such as goat whey to the pigs [41,44,49,71].…”

“…As colostral antibodies disappear by 120 days of age, piglets and young raising pigs do not have any maternal immune protection, and are, therefore, exposed to the infection [71]. However, the humoral immunity alone is not sufficient in combating the parasite.…”

“…The cases of cannibalism by the accidental access to preliminary dead animals, especially when animal tissues are buried or composted are considerably common [41,44,49,71]. Similarly, providing drink water of unknown quality to the pigs, possibly contaminated with the oocysts and feeding of raw animal products such as goat whey is also a potential risk, if made from unprocessed milk containing tachyzoites from a recently infected animal undergoing the dissemination phase [42,75].…”

Toxoplasmosis

Toxoplasma gondii is an obligatory intracellular parasite of mammals, including humans and domestic animals. The infection with this parasite has severe clinical consequences, as it causes abortion or fetal abnormalities, encephalitis in immunocompromised humans, ocular toxoplasmosis with chorioretinitis, and it may contribute to Alzheimer disease. Therefore, an efficient control of T. gondii by prevention of the transmission to humans is strongly recommended. Pork is considered as an important source of toxoplasmosis, due to the frequent consumption of the raw or undercooked porcine meat products, a high susceptibility of pigs to the infection, and because of the numerous risk factors, contributing to the prevalence of toxoplasmosis in the pig population. The cellular and humoral immune responses, such as IgM, IgG, IFN-gamma, and interleukin-10 or -12 production, associated with the acute and chronic infection in pigs, do not prevent development of the tissue cysts, which persist lifelong within the intermediate host. Therefore, the prevalence of T. gondii in the pig population might be an useful indication of the risk associated with the consumption of the porcine meat.

“…Although modern meat production has reduced the prevalence of T. gondii in young pigs in Europe and North America (Tenter et al, 2000), a higher seroprevalence of T. gondii has been observed in sows compared to fattening pigs (Dubey, 1986a;Weigel et al, 1995;Lundén et al, 2002;Damriyasa, et al, 2004;Villari et al, 2009;García-Bocanegra et al, 2010;Alvarado-Esquivel et al, 2011). The higher seroprevalence in sows compared with market age pigs is epidemiologically relevant with respect to transmission of T. gondii.…”

“…Pig meat is an important foodstuff worldwide, and humans can acquire infections with T. gondii by ingesting undercooked pig meat containing tissue cysts. Surveys of seroprevalence of T. gondii infection in pigs have been reported throughout the world (Dubey 2009(Dubey , 2010Garcia-Bocanegra et al 2010;Holec-Gasior et al 2010), and there have also been surveys of T. gondii infection in pigs in several provinces of China in recent years (Suo et al 2006;Zou et al 2009;Huang et al 2010;Zhou et al 2010).…”

Toxoplasma gondii infection is widely prevalent in humans and animals, including pigs throughout the world. In this study, the seroprevalence of T. gondii infection in Tibetan pigs in China was investigated for the first time. A total of 427 serum samples were collected from Tibetan pigs in Nyingchi prefecture, Tibet, between April and December 2010, and were assayed for antibodies to T. gondii using the modified agglutination test (MAT). Ninety-seven (22.72%) pigs were found to be positive with MAT titers of 1:25 or higher. Slaughter pigs had the highest seroprevalence, compared with seroprevalence in fattening pigs, growing pigs, or piglets, although the difference was not statistically significant ( p ‡ 0.05). The results of the present survey indicate that T. gondii is highly prevalent in Tibetan pigs in Tibet, which poses a significant public health concern in this unique region of the world.
