INTRODUCTION Early bacterial colonization of the intestine can alter its morphology, physiology, and susceptibility to infectious diseases (Diaz-Carrasco et al., 2019). The intestinal microbiota plays a critical role in the development and maturation of the gut and its lymphoid structures, and in the function of immune system cells (Hooper et al., 2012; Maki et al., 2019). Initial interaction ...

IntroductionPoultry producers attempt to control infectious diseases through a variety of means, including appropriate farm management practices and breeding genetically resistant lines (Sartika et al. 2011; Scott et al. 2018). Unfortunately, existing farming conditions favour increased chicken densities in poultry houses, increasing the risk of spreading entero-pathogens such as Salmonella and Cl ...

INTRODUCTIONNewly hatched birds have immature and undeveloped immune system (Bar-Shira et al., 2003). Maternalderived antibodies (MDA) play a critical role in early protection against pathogenic organisms (Kramer and Cho, 1970). Maternal antibodies are immunoglobulins that are transferred from vaccinated or naturally infected breeder hens to the progeny through the egg, which provide passive immun ...
