Anticoccidial activity of 8-aminoquinolines, pamaquine, primaquine and several molecular complexes and salts of pamaquine, against Eimeria tenella, E. necatrix, E. acervulina, E. maxima, and E. brunetti in battery experiments.

Primaquine revisited six decades after its discovery

“…Also, a series of experiments were conducted to investigate the anticoccidial activity of pamaquine and PQ, against laboratory strains of Eimeria tenella, Eimeria necatrix, Eimeria acervulina, Eimeria maxima and Eimeria brunette, revealing that both drugs were effective against E. tenella and E. necatrix, but not against the other three species [63]. The anticoccidial activity of PQ has also been tested by Armer et al who found that both PQ and pamaquine possess in vivo anticoccidial activity in broilers against the protozoan parasites E. tenella and E. necatrix [64,65].…”
