Résumé
Intra-specimen and day-to-day variations of Fasciola egg counts in stools were investigated for 16 cases of established fascioliasis. For each case six Kato slides from a single stool sample were examined daily for 5 consecutive days. The results indicated the presence of significant intra-specimen variations in more than one-third of the examined series, while the inter-specimen variation was almost negligible. The sensitivity of the Kato-Katz test for diagnosing Fasciola infection with three Kato slides from the same specimen or on different days ranged from 96.0%-99.1%. The examination of three Kato smears from a single stool specimen, which is more feasible in field studies, would give an accurate diagnosis of fascioliasis. Used as such, the Kato-Katz technique is highly sensitive in the diagnosis of fascioliasis

The efficacy of triclabendazole in the treatment of chronic Fasciola infection was assessed. A total of 134 asymptomatic cases of established Fasciola infection were treated: 68 individuals received a single dose of 10 mg/kg and 66 individuals received 2 doses of 10 mg/kg on 2 consecutive days. Cure was assessed 5 weeks after treatment and 79.4% of the first group and 93.9% of the second group were cured. The drug was well tolerated; no serious side-effects were noted. One patient developed biochemical cholestasis the third day after treatment, but her enzyme profiles returned to normal after 2 months. We conclude triclabendazole is a safe and potent fasciolicidic drug
