“…The Girão and Ueno [1] technique was cited by Abidu [8], as more sensitive compared to a technique involving a commercial kit. Additionally, Mattos, Cunha and Marques [9], found a prevalence of 88.8% with the Girão [11].…”

“…However, when Abidu et al (1996) compared this commercial technique with the sieving method developed by Girão and Ueno (1994), they found that both methods had the same sensitivity, but the latter was fast, simple and less expensive.…”

The sensitivity and utility of a standard faecal sedimentation method (FSM) and a modified stool sieving staining method (FSSM), both currently employed for the diagnosis of Fasciola hepatica infection were compared. Faecal samples were obtained from 51 bovines of an endemic area for fasciolosis in Southwestern Argentina. Each sample was placed in a recipient containing 5% formalin. Eight millilitres of the suspension, equivalent to 2g of faeces, were used for each of the two methods tested. The number of eggs found per sample was recorded. The proportion of positive samples obtained by the FSSM (27/51) was significantly higher than that by the FSM (11/51) (P<0.05). The percent of agreement between methods was 41%. Over a total of 27 positive samples detected by the FSSM, the FSM missed 16, yielding 60% false negative samples. The FSSM enhanced 2.5 times the sensitivity of diagnosis. The complexity of the FSM may decrease its sensitivity through missing and loss of eggs during sample processing. These results confirmed that the commonly used FSM underestimates the prevalence and the egg output in cattle and that the FSSM is a more reliable diagnostic method.Keywords: cattle, Fasciola hepatica, coprological method, diagnosis RESUMO Compararam-se a sensibilidade dos métodos padrão de sedimentação fecal (MPSF) e modificado da tamisação e coloração das fezes (MTCF)-quatro tamises, ambos empregados no diagnóstico de infecção por

“…Outros métodos que utilizam formalina e éter, como solvente, e a centrifugação para concentração de ovos são adaptados e empregados (Shore e Ash, 1973;Grock et al, 1998). Das técnicas mais conhecidas destacam-se as de Watanabe et al (1953), de Dennis et al (1954), de Girão (1982) A eficiência de várias técnicas de diagnóstico utilizadas para a fasciolose, foi estudada por Girão e Ueno (1985), Abidu et al (1996), Anderson et al (1999), Conceição et al (2002) e Kleiman et al (2005).…”

“…Abidu et al (1996), ao compararem as técnicas de filtro de Visser, quatro tamises e Flukefinder ® , observaram convergência de resultados e concluíram que elas poderiam ser utilizadas como rotina no diagnóstico da fasciolose. Girão e Ueno (1985) compararam a técnica de quatro tamises com a de Denis et al (1954) e não observaram diferença quanto ao diagnóstico quantitativo da fasciolose em ruminantes.…”
