A while ago, a pigeon fancier paid me a visit for a routine check-up. The pigeons had received a cure of 8 days with ronidazole 10% (high doses). Upon examination, it appeared that the pigeons were truly full of trichomoniase!

Most medicines for internal use, however they are administered (by mouth, injection, spraying), have to be absorbed from the point at which this occurs, i.e. have to travel further in order to reach the appropriate organ or organs. There are clear differences in the way the various active ingredients are absorbed, and to ignore these can cause treatment to be unsuccessful.
