A case of trichurosis in gilts and fattening pigs

Case presentation: This report presents a case of trichurosis diagnosed in a farrow-to-finish Belgian pig herd. The infection was associated with severe and persistent diarrhoea, growth retardation, emaciation and/or anaemia in 10 recently purchased gilts and in fattening pigs. In gilts, levamisole [8 mg (kg body weight)] administered once per os gave a good clinical response, as diarrhoea resolved in nine gilts out of 10. In parallel, for these nine gilts, the number of eggs of T. suis (g faeces passed) decreased from 12 400 to less than 100 eggs. In fattening pigs, flubendazole (1 mg kg) administrated over 5 days in drinking water allowed a reduction in the number of T. suis eggs g and was effective against diarrhoea.
