Therapeutic effects of some antihaematozoal drugs against Haemoproteus columbae in domestic pigeons.

Three antihaematozoal drugs were tested for the treatment of pigeons naturally infected with Haemoproteus columbae. Butalex (Buparvaquone) was found effective against the parasite either by using the recommended dose (R. D.) or the double (D. D.) dosis. The R. D. of Berenil (Diminazene aceturate) was not effective while the D. D. reduced the number of gametocytes circulating in the infected blood. Triquine was found very toxic to the pigeons both the R. D. and the D. D.
