“…Infections of the duodenum, jejunum or ileum cause reduced absorption of nutritional elements by the intestinal epithelium.

Coccidiosis and necrotic enteritis (NE) are globally common, sometimes intercurrent, diseases of poultry. The risk of NE, due to the Gram-positive bacterium Clostridium perfringens, has increased in recent years because of the voluntary or legally required withdrawal of the use of certain in-feed antibiotic growth promoters with anticlostridial activity. In-feed ionophorous anticoccidial drugs incidentally also possess anticlostridial activity. Such ionophores, although not banned, are usually precluded when live anticoccidial vaccines are used, potentially increasing yet further the risk of NE. This review provides information for the design of rational, integrated management strategies for the prevention and control of coccidiosis and NE in chickens by maintaining gut integrity. Because of differences in local availability of feed ingredients and national legislations regarding antibiotic growth promoters and anticoccidial vaccine licensing, no universal strategy is applicable. The diseases and their interactions are described under the headings of forms of disease, diagnosis, sources of infection, pathophysiological effects, predisposing factors, and control methods. Elements of gut integrity, which influences host predisposition and clinical responses to disease, include physical development, immune competence, gut enzyme activity, mucin production, gut flora and epithelial damage. Experimental studies of coccidiosis and NE are compared, and where possible reconciled, with field observations. Gaps in knowledge and necessary further experiments are identified. Insights are provided regarding interactions between coccidiosis, NE, and the use of live anticoccidial vaccines. Recent changes in NE prevalence in commercial flocks, and their possible causes, are discussed. The necessarily wide range of topics reviewed emphasizes the enormous complexity of this disease combination, and indicates the importance of a multidisciplinary approach in order to reduce its harmful impact on the world's poultry industry.

“…Giese et al (1971) orally administered 14 C-glucose to infected chicks and then determined relative glucose absorption through the measurement of 14 C radioactivity in liver, blood, and muscle. Such studies are necessary to assess the relative importance of defective absorption and defective utilization of nutrients in their contribution to the growth rate of infected chickens.…”

The decrease in B-RA on each experimental day from the .5 hr to the 4 hr interval in all trials except trial 5 was undoubtedly due to glucose metabolism and removal from the bloodstream.…”

Results of five trials with four species of coccidia (Eimeria acervulina, E. necatrix, E. tenella, and E. brunetti) failed to demonstrate any interference with glucose absorption in the parasitized intestines of intact chick hosts. In addition, circulating blood radioactivity in severely parasitized chicks, as evidenced by weight gain data and intestinal lesion scores, was significantly higher than that in control chicks following oral administration of 14C-glucose or 3-0-methyl-D-14C-glucose at 6 days postinfection. During the recovery phase of the infection (14 to 21 days postinfection), severely infected chicks rapidly gained weight and the blood radioactivity of parasitized chicks was consistently higher than that of uninfected control chicks. No significant differences in weight or blood radioactivity were observed during the post-recovery period (28 to 35 days postinfection).

“…Ces effets qui s'accompagnent d'une acidose duodénale (Kouwenhoven et van der Horst, 1973) se traduisent sur le plan physiologique par une diminution de la vitesse d'absorption de certains nutriments. Il en est ainsi pour le glucose (Giese et al, 1971;Sykes et Walters, 1971), le zinc et l'acide oléique (Turk et Stephens, 1967). Dans le cas des acides aminés, les résultats sont controversés.…”

The absorption rate of 14C L-lysine and net flux of water and mineral ions (Na+, K+) were studied in 4-week-old male chickens infected with Eimeria acervulina (10(6) sporulated oocysts/chicken). Intestinal coccidiosis significantly decreased absorption rate of 14C-lysine. This effect was particularly pronounced in the jejunum. Net flux of water was also modified: its absorption was decreased in the middle and distal small intestine. In the duodenum a net absorption of water was converted to a net excretion. These effects were accompanied by an increase in tissue water content and in secretion rate of Na+ and K+.
