“…The prevalence of cysticercosis is inextricably linked to several risk factors that drive the transmission of cysticercosis. Some of the risk factors related to the prevalence of cysticercosis that have been reported are the farming system [25], the level of public sanitation [26], unhygienic feed given to livestock [27],…”

Background and Aim: Cysticercosis is a zoonotic disease with a global concern. Estimation of the prevalence and identification of potential risk factors are necessary for the prevention and control of the disease. This study aimed to estimate the seroprevalence of cysticercosis and the correlation of the increased prevalence with several potential risk factors. Materials and Methods: The seroprevalence of cysticercosis was conducted using an enzyme-linked immunosorbent assay (ELISA), developed by the Institute of Tropical Medicine Antwerp, to detect Cysticercus cellulosae. This study used serum samples from 62 pigs taken from two regencies on Timor Island. The data analysis was performed using SPSS software 20.0 (IBM Corp., NY, USA) to evaluate ELISA results and the strength of the relationship between risk factors and the prevalence of disease using the odds ratio (OR). Results: Serum samples from 18 out of the 62 pigs were found to be positive; the seroprevalence of cysticercosis was 29%. The results showed that an extensive farming system led to a higher prevalence of cysticercosis compared to an intensive farming system, namely, 10 out of 18 (56.6%), and that the possibility of identifying cysticercosis in pigs in an extensive farming system was 5 times greater than that in pigs in an intensive farming system. In addition, the results showed that nine out of 18 households who did not have toilet facilities were found to be seropositive, indicating a significant relationship between the risk factor of toilet availability with cysticercosis in pigs, with an OR of 4.5. In addition, the results showed that there was no significant relationship between the risk factor of the feed source and the prevalence of cysticercosis in pigs. Conclusion: It can be concluded that the seroprevalence of cysticercosis was 29% in domestic pigs of Timor Island. The risk factors of an extensive pig farming system and toilet availability in community houses were significantly related to the possibility of cysticercosis on Timor Island.

“…The development of immunoassay techniques has resulted in a practical and efficient alternative for the diagnosis of animal cysticercosis. The ELISA and Western Blot tests have been applied to determine the epidemiological profile of this zoonosis (Pinto et al 2000a, Monteiro et al 2006, Acevedo Nieto et al 2012, Santos et al 2013, Acevedo-Nieto et al 2017, Guimarães-Peixoto et al 2020. The use of questionnaires is another important tool for identifying risk factors (Souza et al 2013, Kusolsuk et al 2021.…”

Thousands of families live in agrarian reform rural settlements, these existing in Brazil since the 1980s. Factors such as agglomerations of families living in the same environment and the production of domestic animals can promote the transmission and maintenance of zoonosis in these areas. The epidemiology and geographic distribution of zoonotic diseases in settlement communities need to be highlighted. The present study aimed to investigate the prevalence, risk factors and spatial distribution of the teniasis-cysticercosis complex in the agrarian reform rural settlements in the state of Minas Gerais. A total of 497 family farming properties, distributed in 52 settlements, were randomly selected and sampled. Biological samples of humans, cattle and pigs were collected and processed. Survey questionnaires were applied in each family farming property to collect data on animal production as well as sanitary, hygienic and social conditions of each family. Human fecal samples were analyzed for detection of teniasis infection, while animal blood samples were collected and subjected to serological testing to detect the cysticercosis infection. A total of three (0.35%) positive cases of human teniasis were identified, 64 (4.2%) of bovine cysticercosis and 17 (3.3%) of swine cysticercosis. Prevalence per family farming unit was 0.6% (3/497) of taeniasis through fecal test, 5.8% (17/294) for swine cysticercosis and 11.1% (52/469) for bovine cysticercosis. The spatial profile for human teniasis and swine cysticercosis were clustered in two different regions, while bovine cysticercosis showed a dispersed geographical distribution. Two risk factors were associated with the occurrence of bovine cysticercosis: stream as source of water (p=0.009) and the environment as destination of sewage (p=0.031), while burning of garbage was shown to be a significant protective factor (p<0.001). Risk factor for swine cysticercosis was associated with the presence of free range pigs (p=0.008) and the environment as the destination of sewage (p≤0.024). The low number of positive human taeniasis did not allow statistical analysis. These zoonotic diseases represent a significant risk to public health because of their occurrence in livestock which are produced for both beef consumption and for commercialization. Significant endemic areas in the state of Minas Gerais have been determined in this study, and these discoverments suggest the importance of further investment in public health education about teniasis-cysticercosis transmission, the improvement of sanitary facilities for the settlements such as source and treatment of water and adequate destination of sewage. Integrated actions between the human, animal and environmental health sectors, at local and regional levels are needed, aiming at the adoption of effective public policies for the control and eradication of the teniasis-cysticercosis complex where the disease occurs.
