The role of host genetic factors and host immunity in necrotic enteritis.

The role of host genetic factors and host immunity in necrotic enteritis. Avian Pathol. 2016 Mar 9;:1-11 Authors: Oh ST, Lillehoj HS Abstract The increasing number of legislative restrictions and the voluntary withdrawal of antibiotic growth promoters worldwide will continue to impact poultry health and production. The rising incidence of Clostridium infections and development of necrotic enteritis (NE) in commercial chickens has been associated with the withdrawal of antibiotics. High-throughput genomic analysis of intestinal tissues from NE-afflicted chickens showed alterations in the local immunity and gut microbiota. Therefore, a better understanding of host- and environmentally-related factors on Clostridium perfringens infections will be necessary for the development of effective sustainable strategies aimed to reduce the negative consequences of NE. In this short review, we summarize the current knowledge on the role of host genomics and immunity in NE. The limited progress in understanding the complexity of host-pathogen interactions in NE underscores the urgent need for more fundamental research in host immunity against Clostridium pathogens in order to develop effective control strategies against NE.
