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

Abstract

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.

“…No continente americano, dados sobre a cisticercose bovina revelam prevalências de 0,1 a 18% no Brasil (de Aragão et al, 2010;Rossi et al, 2016Guimareaes-Peixoto et al, 2020; 5,8%, no Canadá; 7,9% no México e 0,2% nos EUA . Na Europa, a cisticercose bovina tem sido relatada nas últimas décadas, com prevalência de 0,59 a 6,06% na Áustria; 0,49 a 1,61% na Bélgica; 5,30 a 6,47% na Alemanha e 6,29 a 12,68% em Portugal (Laranjo- .…”

“…Registros de prevalência em países africanos variam de 2,3% a 48,2% no Gana e Burkina Faso respectivamente . Na América, prevalências foram estimadas no Brasil entre 2,8 a 6,82% (Rossi et al, 2016; e 0,05 a 33% no México (Morales et al, 2008;Bhattara et al, 2019). Na Europa, prevalências variam de 0,0023% na Alemanha a 0,43% na Espanha (Laranjo-Gonzalez et al, 2017).…”

“…A correta interpretação dos resultados do immunoblot depende da correta identificação das bandas com poder diagnóstico (Silva et al, 2015b). Vários estudos apresentam em comum no resultado positivo ao Immunoblot a marcação de bandas de peptídeos de baixo peso molecular (Magalhaes et al, 2017, Guimarães-Peixoto et al, 2016.…”
