the cellular response of the fowl small intestine to primary and secondary infections of the cestode raillietina cesticillus (molin).infections of raillietina cesticillus in the small intestine of the fowl caused a mononuclear leucocyte infiltration, which occurred in the tissues around the worm scolices and was especially prevalent in challenge infections. there was no evidence of vascular congestion or of a neutrophilic response, and the cellular reaction seemed to consist of a local proliferation of lymphoid tissue. mast cell and pyroninophylic cell numbers increased in the intestinal mucosa of birds with longstanding prim ...1976988531
dose-titration to confirm the level of fenbendazole for control of raillietina cesticillus in broiler chickens.a total of 452 broiler chickens, naturally infected with raillietina cesticillus, were allotted into six treatment groups. one group was fed unmedicated broiler ration (group 1), and the other five groups were fed broiler ration containing fenbendazole at 180 ppm for 3 days (38.5 mg/kg body weight [bw]), 240 ppm for 3 days (50.9 mg/kg bw), 120 ppm for 6 days (52.2 mg/kg bw), 180 ppm for 6 days (79.9 mg/kg bw), or 240 ppm for 6 days (104.3 mg/kg bw). fenbendazole was 100.0% efficacious against r. ...19921417603

scanning electron microscope examination of scale-like spines on the rostellumm of five davaineinae (cestoda, cyclophyllidea).the study by scanning electron microscope of the scolex of cotugnia polyacantha, raillietina (r.) echinobothrida, r (r.) tetragona, r.

comparative histochemical observations on the excretory system of helminth parasites.the excretory canals of ascaridia galli (nematoda) and the protonephridial ducts of cotylophoron cotylophorum (trematoda) and raillietina cesticillus (cestoda) have been studied with regard to the histochemical localization of lipids, carbohydrates and hydrolytic enzymes. distinct excretory organs are absent in the acanthocephalan centrorhynchus corvi. triglycerides, phospholipids and lipoproteins are seen in association with the wall of excretory canals of a. galli and r. cesticillus, and phosp ...1977196423
efficacy of fenbendazole against naturally acquired raillietina cesticillus infections of chickens.birds were obtained from a commercial broiler operation where birds were naturally infected with raillietina cesticillus at an incidence of 40%. fenbendazole was added to the diet for six consecutive days at 30, 60, 120 or 180 mg/kg or at 60 or 120 mg/kg for 3 days. birds were necropsied over a 3-day period beginning 4 days after fenbendazole withdrawal. anthelmintic efficacies for the 6-day regimens of fenbendazole at the dietary rates of 30, 60, 120 and 180 mg/kg were 76, 73, 77 and 95%, respe ...199218670945
the diurnal migration of the fowl cestode, raillietina cesticillus.r. cesticillus was found to undergo a diurnal migration in both multiple and single worm infections of the fowl. this migration involved movement of both scoleces and strobilae and occurred in an anterior direction when the intestine was empty of food, and in a posterior direction when the intestine contained food. the relevance of the migration to the histological picture of the worm in situ is discussed and some possible explanations for the migration are suggested.1977564499
