“…Similar discrepancies between meat inspection data and serology screening were observed for beef cattle in Sweden in 2007 (Novobilský et al, submitted), where seroprevalence and abattoir prevalence were 10% and 3.5%, respectively. Similar observations were reported from Switzerland, where infected livers were detected only in two-thirds of seropositive animals at abattoir inspection (Rapsch et al, 2006). Charlier et al (2008) showed that only one third of F. hepatica infected livers was detected by standard meat inspection cuts, that Fig.…”

“…This technique can only detect patent infections and thus there is a limit to the sensitivity that can be achieved. It is possible that repeated faecal examinations could improve the sensitivity as has been shown elsewhere (eg fasciolosis in cattle, Rapsch et al, 2006). Some of the animals which had worms in the purge sample but had no eggs in faeces were probably pre-patent infections on the basis of morphological analysis of the recovered worms.…”

“…Bayesian techniques were used to estimate unknown sensitivities of the two diagnostic procedures using an appropriate spreadsheet model and macro programming in Excel (Rapsch et al, 2006). It was also assumed that the sensitivities of the tests were correlated and parameters for the model were applied accordingly.…”

“…La sensibilidad de estas pruebas podrían incrementarse con toma seriada de muestras (Rapsch et al 2006), aspecto que no podría hacerse en este caso debido a la dificultad en el manejo de la vicuña, cuya captura es realizada una vez al año, y donde solo se pudo extraer cerca de 15 g de heces por animal.…”
