“…Application of Taenia coproantigen ELISA for mass screening, with use of PCR for species confirmation and to differentiate T. solium infection from T. saginata (or T. asiatica in Asia) carriers, together with a specific immunoblot test for human/porcine cysticercosis, has been very useful in epidemiological studies [2,4,5 ,8 ,11,20]. These and other studies indicate that T. solium specimens from carriers in endemic communities are relatively small (average 2-3 m) compared with T. saginata (average 4-5 m), the worm has a relatively short life-span of less than 2-5 years, tapeworm re-infection occurs readily in endemic communities, and even egg transfer from pig to pig by coprophagia may be possible [21 ]. T. solium tapeworm carriers have also been shown to exhibit high rates of seropositivity to oncosphere antigens, which suggests exposure to eggs and thus risk of neurocysticercosis, but also possibly for some individuals development of anticysticercosis immunity [22].…”

Human intestinal cestode infections are globally primarily caused by species in three genera: Taenia, Hymenolepis or Diphyllobothrium. Sporadic zoonotic infections caused by nontaeniids are usually food-borne or due to accidental ingestion of invertebrate hosts. Intestinal cestode infections generally result in only mild symptoms characterized chiefly by abdominal discomfort and diarrhoea. Most human intestinal cestode infections can be treated with a single oral dose of praziquantel or niclosamide.

“…On the other hand, an earlier study on human cysticercosis conducted in the same area found high prevalence of the infection (Assane, 2009). Human cysticercosis has been associated with the presence of tapeworm carrier in a household (Garcia-Garcia et al, 1999), whereas infected pigs allegedly have a tendency to cluster around tapeworm carriers (Gonzalez et al, 2006).…”

“…Pigs get infected with the cysticerci by ingesting food or water contaminated with T. solium eggs, parasite segments, human feces containing eggs (OIE 2014) or even direct pig-to-pig transmission (Gonzalez et al 2006). The main risks factors associated with swine cysticercosis are free-range husbandry system, absence of bathrooms in the rearing farms, contaminated water ingestion (Sikasunge et al 2007, Morales et al 2008) and slaughter without sanitary inspection (Pinto 2000).…”

Testing pigs of non-technified rearing farms for serum antibodies against Taenia solium in a region of the state of São Paulo, Brazil

Taenia solium is a zoonotic tapeworm of great importance in developing countries, due to the occurrence of human taeniasis and cysticercosis. Pigs have an important role in the biological cycle of the parasite as intermediate hosts. The scientific literature has been describing risk factors associated with the occurrence of this disease that must be avoided in countries with poor sanitation, in order to reduce the exposure of swine to the parasite eggs. This research focused on testing pigs of non-technified rearing farms for serum antibodies against Taenia solium in the region of Jaboticabal municipality, in the state of São Paulo, Brazil. The found prevalence was 6.82% (CI 95% 4.18 - 9.45) at animal level and 28.87% (CI 95% 16.74 - 40.40) at herd level. These figures are probably associated with low technification adoption during animal rearing in the studied area, which increased the exposure of the animals to risk factors associated with the occurrence of Taenia solium complex. The results found based on serological evidences of swine cysticercosis in the studied region serves as a warning to public sanitary authorities to improve public health and control T. solium.
