During August, 1951, two White Leghorn chickens about three months old were brought to the Diagnosis Department of Dr. Salsbury's Laboratories because the birds were droopy and not developing properly. The death loss in the flock had been about five percent. At necropsy these birds showed enlarged spleens, congested livers and pale kidneys. A catarrhal enteritis was found in the jejunum and associated with this were numerous flukes. Unfortunately none of these were saved for identification. The flock-owner was instructed to move the birds away from the area in which they had been maintained and to treat the birds with a proprietary anthelmintic, WORMAL, containing the active ingredients nicotine, phenothiazine and dibutyltin dilaurate. The tetravalent tin compound has recently been shown to be effective against poultry cestodes, Kerr (1952).
