“…Densely human populated areas (Fig.4) were associated as a risk factor for bovine cysticercosis, as previously described in the state of Mato Grosso, Brazil (Rossi et al 2016), and pointed as potentially involved in the different prevalence established among Brazilian states (Rossi et al 2015). Only one proglote of T. saginata can harbor up to 100,000 eggs resulting in a high environmental contamination (CDC 2016).…”

“…0.013-0.014) is lower than other established in several other Brazilian states, such as São Paulo (2.92%), Minas Gerais (1.81%), Goiás (0.71%), Mato Grosso do Sul (1.11%) (Rossi et al 2015), Paraná (2.23%) (Guimarães-Peixoto et al 2012), Espiríto Santo (1.02%) (Avelar et al 2016) and Mato Grosso (0.0873%) (Rossi et al 2016). Other paper published regarding bovine cysticercosis prevalence in the same state, showed a prevalence of 0.07% (4,420/6,239,172) through the years 2007 to 2010 (Dutra et al 2012), enforcing the theory that a reduction in the prevalence might be ongoing in this state.…”

“…Even though the disease presents worldwide distribution, the highest prevalence rates are present in developing and underdeveloped countries (OIE 2008), such as Brazil (Dutra et al 2012). Scientific studies in several different brazilian states such as Paraná (Guimarães-Peixoto et al 2012), Espiríto Santo (Avelar et al 2016), Mato Grosso (Rossi et al 2016) and Bahia (Bavia et al 2012), have been performed in order to improve the understanding regarding bovine cysticercosis epidemiology and perpetration in Brazil.…”

“…Among the identified risk factors, the most important were cattle herds' access to contaminated water sources, presence of fishing activities near grazing areas (Rossi et al 2015); contaminated feed sources (Jenkins et al 2013), organic production systems (Calvo-Artavia et al 2013a), use of sewage sludge to irrigate pasture (Cabaret et al 2002) and proximity to densely populated areas (Rossi et al 2016).…”

This study focused on assessing the prevalence, geospatial distribution and risk factors for bovine cysticercosis in cattle from the state of Rondônia, Brazil, through the years 2012 to 2015. The prevalence established was 0.014% (95% C.I. 0.013-0.014), with a higher detection of unviable cysticerci (84.80%). The municipalities of Itapuã do Oeste, Candeias do Jamari, Nova Brasilândia D’Oeste, Pimenteiras do Oeste, Porto Velho, Nova Mamoré, Urupá and Guajará-Mirim had higher risk (OR>1; p<0.05) for cysticercosis occurrence compared with the municipality of Castanheiras (OR=1). The Administrative Regions of Porto Velho, Guajará-Mirim, Colorado D’Oeste, Cacoal, Ji-Paraná had higher risk (OR>1; p<0.05) for cysticercosis occurrence in the slaughtered animals than those reared in Ariquemes Administrative Region (OR=1). Some variables such as human population density (OR=2.15; 2.15-2.16), percentage of urban houses with inappropriate sewage system (OR=1.91, 1.91-.1.92) and percentage of inappropriate rural sewage system (OR=1.14, 1.14-1.14) were significantly associated (p<0.05) with the occurrence of bovine cysticercosis. In conclusion, the prevalence of bovine cysticercosis in the state of Rondônia was 0.014% (95% C.I. 0.013-0.014) and higher-risk areas were identified, providing useful information to Official Sanitary Inspection System in order to improve cysticercosis detection. Also, human population density and the lack of appropriate sewage system in urban and rural areas are closely related to bovine cysticercosis occurrence in this state.
