“…The diagnosis of drug efficacy is often based on faecal egg counts, so the observation of such a rapid cessation of egg production would imply that any eggs recovered after successful treatment would be due to the storage and release of eggs from the gall bladder and not to eggs produced by any surviving flukes themselves. It is known that eggs can be stored in the gall bladder for several weeks after successful drug treatment and this fact needs to be taken into account when assessing drug efficacy (Flanagan et al, 2011b). Stunting and suppression of egg production in adult flukes surviving treatment with TCBZ and other fasciolicides, also the delayed development of juvenile flukes following treatment, have been described on several occasions (for references, see Toner et al, 2011a).…”

“…Em estudo realizado para avaliação do sucesso do tratamento da fasciolose com o triclabendazole, FLANAGAN et al (2011) observaram que apenas após a 14 semana pós-tratamento é que o número de ovos cai 95% e os níveis de coproantígenos não podem mais ser detectados nas fezes do hospedeiro, o que pode justificar o diagnóstico positivo das amostras provenientes dos animais cujos fígados foram condenados, sem que se tenha encontrado exemplar de F. hepatica.…”

“…No entanto, técnicas que detectam antígenos nas fezes de hospedeiros infectados vêm sendo aprimoradas para um diagnóstico mais precoce e acurado da fasciolose (ESTUNINGSIH et al, 2009;FLANAGAN et al, 2011). FLANAGAN et al (2011) citam que os testes para detecção de coproantígenos diagnosticam a doença mais precocemente do que os exames coproparasitológicos.…”

“…The finding of 50 % ECR % for distilled water could be attributed to physical injury of the worms due to undigested fibrous feed material or peristaltic movements in the cecum leading to the expulsion of the worms out of the gut. Flanagan et al (2011) and Levecke et al (2012b) stated that fecal egg count reduction test (FECRT) is one of the recommended diagnostic assays for monitoring anthelmintic drug efficacy against gastro-intestinal nematodes in livestock. However, necropsy could have therefore been performed in the current study to confirm treatment efficacy.…”
