“…There is limited published research on the serological diagnosis of fasciolosis in cattle. The previous studies have reported fasciolosis seroprevalence rates of 56% in Uruguay [30], 5.9% in Estonia [31], 9% in Iran [32], and 63.56% in Mexico [9], which are lower than those found in the municipalities evaluated in the present study. However, Alba et al [5] indicated that 90% of the cattle evaluated in Corsica (France) were positive for anti-F. hepatica antibodies, showing a wide distribution of the parasite in the area.…”

Background and Aim: Bovine fasciolosis is a reemerging neglected disease with a worldwide distribution caused by the trematode Fasciola spp., which parasitize various hosts. Bovine fasciolosis is responsible for large economic losses in the bovine livestock sector. This study aimed to estimate the seroprevalence and risk factors of bovine fasciolosis in the municipalities of Colombia. Materials and Methods: This was a descriptive cross-sectional study with simple random sampling conducted on 1140 cattle from the municipalities of Chiquinquir´, San Miguel de Sema, and Ubaté for a duration of 3 months. Serum samples were processed using the commercial Fasciola hepatica Antibody Test Kit IDEXX® Fasciolosis Verification (IDEXX, United States), which identified immunoglobulin G antibodies for gf2 antigen purified from Fasciola extracts. The f2 antigen is extremely immunogenic and highly specific for F. hepatica. An epidemiological survey was performed to record variables related to the sampled animals and herd management practices. Data were processed using the statistical program Epi Info® (Centers for Disease Control and Prevention; Atlanta, Georgia). The prevalence ratio was estimated to evaluate the association between fasciolosis and the hypothesized causal factors and the significance of this association using Pearson’s Chi-square test. Finally, a logistic regression model was developed. Results: The overall seroprevalence was 72.3%. The seroprevalence was 83.9% (323/385) in Chiquinquirá, 68.17% (257/377) in Ubaté, and 64.55% (244/378) in San Miguel de Sema. The seroprevalence was higher in male animals in Chiquinquirá and in female animals in San Miguel de Sema and Ubaté. Similarly, sex showed a statistically significant association with disease prevalence in Ubaté. The highest prevalence was found in cattle aged >2 years. The Holstein breed showed maximum seroprevalence in Chiquinquirá (p ≤ 0.05) and San Miguel de Sema, whereas crossbreed showed higher seroprevalence in Ubaté. Similarly, in Chiquinquirá, the association between the seroprevalence of fasciolosis and the presence of other species was statistically significant (95% confidence interval [CI]: 0.9601–3.4944; p = 0.0448). In Ubaté, the disease presentation was also associated with pasture rental (95% CI: 0.4047–1.0023; p = 0.003) and attendance to livestock expositions (95% CI: 0.2313–1.0636; p = 0.044). However, in San Miguel de Sema, water from the stream showed a statistically significant association with disease presentation (95% CI: 0.5209–1.0985; p = 0.00649785). Female sex and diarrhea occurrence were considered risk factors for fasciolosis. Conclusion: A high seroprevalence of antibodies to Fasciola spp. was detected in cattle in the study municipalities, indicating a high parasite distribution in these areas. Female sex and diarrhea were established as risk factors associated with fasciolosis in Ubaté and San Miguel de Sema, respectively. Further, research is necessary to establish prevention and control programs against parasitosis. Keywords: bovine, fasciolosis, risk factors, seroprevalence.

“…El contagio se presenta por factores biológicos, climáticos y topográficos; la variación del clima genera un cambio de ecosistema y trae hospedadores a zonas nuevas (Sanchis et al 2015), éste cambio climático se ve más acentuado en los trematodos, se verifica mediante un incremento de la formación de los estados larvarios libres, que influyen en los hospedadores vertebrados e invertebrados (Mas-Coma et al 2008), en un futuro próximo los lugares fríos y de altitudes que sobrepasan los 4000 msnm pueden llegar a ser zonas endémicas (Londoñe et al 2009, Mas-Coma et al 2008, debemos recalcar que la distribución espacial de F. hepática no solo depende de la precipitación, elevación y tipo de suelo; sino que incluye otros factores de riesgo como manejo, en este punto la segada de los pastizales y la proporción en la dieta (Bennema et al 2011), convirtiéndose la enfermedad de alta prevalencia, con elevadas pérdidas en la producción que influye drásticamente en la inocuidad alimentaria; además, incrementa la intensidad y frecuencia de este helminto (Charlier et al 2016). Sin dejar a un lado las prácticas agrícolas sin control y transporte inadecuado de los animales que influyen en la propagación del parásito (Fernández et al 2012).…”

“…Una de las principales causas de presencia de F. hepática, es el tratamiento incorrecto de heces que contaminan los pastos del lugar en donde se encuentran y contraen la infección al ser consumido por el animal (Correa et al 2016, Sanchis et al 2015, para ello es necesario mantener una limpieza continua de los zonas de pastoreo y sus alrededores, y así se logrará reducir el número de parásitos que provocan esta enfermedad (Kalu 2015a, Uduak 2015. Los programas de prevención son considerados más eficaces que los tratamientos farmacológicos aplicados en animales infectados, ya que de esta manera se evitará el contagio a animales sanos (Chávez et al 2012, Godoy et al 2010.…”

La Fasciola hepática es un parásito que pertenece a la clase Trematoda del orden Digenea, que mantiene una amplia distribución mundial. El pasto contaminado con heces es la principal fuente de transmisión, los caracoles intervienen como parte esencial en el ciclo biológico. Las lesiones principalmente están en el hígado y la sintomatología clínica es gastrointestinal secundaria en la afectación hepática. El diagnóstico puede ser parasitológico a partir de métodos de flotación o sedimentación, inmunológico a partir de pruebas como ELISA y en la necropsia con base a los hallazgos anatomopatológicos. La prevención se basa en el control del hospedador intermediario, dejando en segundo grado el tratamiento farmacológico de los animales. En el ámbito económico la incidencia de F. hepática puede ser un riesgo para cualquier producción pecuaria, la prevención o diseminación de esta, mejora significativamente la rentabilidad, de la misma manera las consecuencias de esta enfermedad son las pérdidas económicas en los decomisos de las canales y su elevada mortalidad. Esta revisión abarca algunos aspectos relevantes sobre la infección por F. hepática en países latinoamericanos donde la infección ganadera por este parásito es muy elevada, siendo necesario la intervención sanitaria inmediata en zonas endémicas. 2017.

“…There is a great variation in the prevalence recorded in Latin America where countries such as Brazil, with industrial livestock, report numbers of 18.6% for the state of Rio Grande do Sul and 24.9% for the state of Espíritu Santo, with 7.32% being recorded between 2002 and 2011 nationwide (Molento et al 2018). In Uruguay, parasitosis exceeds 50% prevalence in productive farms (Sanchís et al 2015) while in Mexico, where human fascioliasis is significant (Mas-Coma et al 2014), condemnation in abattoirs due to F. hepatica reaches 20.99% (Rangel and Martínez 1994). On the other hand, Costa Rica has low prevalence levels (1.82%) of adults of F. hepatica after veterinary inspection (Rojas and Cartín 2016).…”

Fascioliasis is a widely distributed parasitic zoonosis caused by the trematode Fasciola hepatica that affects livestock production and generates high economic losses. In Chilean authorised abattoirs, the infected livestock livers are condemned during the veterinary inspection. This study aims to evaluate the prevalence of fascioliasis in Chile from 2014 to 2016 and also monthly from 2002 to 2015 in livestock (cattle, pig, sheep, horse and goat) slaughtered in abattoirs of La Araucanía region, southern Chile. To do this, the available records on abattoirs provided by the sanitary authority were analysed. A descriptive statistics and trend analysis of the data by jointpoint regression was carried out. The Biobío and La Araucanía regions registered the highest levels of parasitosis in the country recording levels of 59.18 and 44.74%, respectively, and presented 50.03% of the liver condemnation rate in cattle. During the study period, a total of 2,239,164 animals were slaughtered and 40.59% infected livers with F. hepatica were condemned in the 9 existing abattoirs of La Araucanía region. The abattoirs located in the cities of Temuco (51.43%) and Angol (65.09%) recorded the highest percentages of fascioliasis. The cattle species recorded the highest number of slaughtered animals and liver condemnation (54.52%). The presence of the parasite was recorded annually and monthly and it was possible to observe a slight increase in fascioliasis over the years. This study provides updated information on the fascioliasis prevalence in the country and the dynamics of condemnation in endemic areas such as La Araucanía region, which could contribute to the control and prevention of this zoonosis.
