A Study of Aqueous Colloidal Sulphur in the Control of Eimeria Tenella in the Fowl

PRIOR to the work of Tyzzer (1927), Johnson (1938), Levine (1938), and others, all coccidia infecting the domestic fowl were classified as Eimeria avium. Seven species of coccidia now have been identified. They are: Eimeria tenella, Eimeria acervulina, Eimeria mitis, Eimeria praecox, Eimeria maxima, Eimeria necatrix, and Eimeria hagani. Of these seven species Eimeria tenella is of the greatest economic importance, usually attacking brooder house chicks between the ages of 3 and 10 weeks.Before 1920 little was known of the control of coccidiosis, except through limitation of infection. The past two decades have witnessed many reported preventive and curative measures. In the absence of controlled experimental data, the reported “cures” may be attributed largely to a sub-fatal dose or to the careful nursing attention given infected broods during the attack.Beach and Corl (1925) tested a large number of medicinal agents and found them to be of little value .
