In this review we reminded characteristics of chicken gut anaerobes and related them to the probiotic potential of individual gut microbiota members. By comparison of already published data we proposed that bacterial species from the intestinal tract which exhibit any form of adaptation to aerobic environment (spore forming bacteria, aerotollerant or facultative anaerobes) are less efficient in the colonisation of chicken intestinal tract and are therefore less suitable as probiotics intended for a single dose administration.
