To perform direct identification of parasites, particularly ova present in faeces, it is possible to use faecal smears, flotation and sedimentation tests. Faecal flotation is fast and inexpensive, and can be quickly implemented as a measure for infection control. Herewith we describe the Willis method, one of the most used flotation methods.engWillis methodParasitesDiagnosticjournal article10.12968/vetn.2017.8.7.398
