The Activity of Bisphenols and Diphenols Against Cecal Coccidiosis (E. Tenella) in Chickens

Bisphenols for the Control of Cecal Coccidiosis

“…None of the birds were given medication during the reinfection. Johnson, Mussell and Dietzler (1949) found that in moderate infections of chickens with Eimeria tenella the series of compounds under study gave a very high degree of protection when used as prophylactic agents, that is, when administered to the birds before infection had taken place. The purpose of this work was to study the effects of the drugs in very severe infections, infections in which a very high percentage of the untreated birds die.…”

“…The purpose of this work was to study the effects of the drugs in very severe infections, infections in which a very high percentage of the untreated birds die. The type of infection used by Johnson, Mussell and Dietzler (1949) is the type which we have most frequently encountered in farm outbreaks of the disease. The severe infections described in this paper have been, in our experience, of relatively uncommon occurrence under natural conditions.…”

“…The purpose of this paper is to report on a new series of compounds described by Johnson, Mussell and Dietzler (1949) as having marked coccidiostatic value when used to prevent moderate coccidial infections and which as here described give significant protection against severe infection. These compounds do not have the disadvantages noted above of the sulfonamides or sulfur, and in addition have certain useful properties still being studied.…”

“…Hereafter, the above compounds will be referred to by their laboratory code numbers as respectively, (1) K1409, (2) K3579, (3) K6605, and (4) K6606. For a more detailed description of their structural formulas see the report of Johnson, Mussell, and Dietzler (1949).…”
