The Diagnosis ofIsosporaoocysts in piglets: a comparison of three coprological methods

Copromicroscopic examination carried out by sedimentation and flotation in a hypersaturated NaCl solution, with or without the addition of sugar, is commonly used to diagnose coccidian oocysts in swine. It has recently been pointed out that it would be preferable to use methods based on the elimination of the fatty matter, which is abundantly present in the faeces of piglets, for detecting these oocysts. The employment of suitable copromicroscopic methods would allow the investigator to identify the presence of oocysts even in farms where parasitosis occurs in a sub-clinical way.
