[Bacteria in the secretion of auxiliary sacs in the opening of the cheek pouches in Campbell hamsters].

A specific and balanced bacterial community exists in the secrete of auxiliary sacs (AS) in the opening of buccal pockets of Campbell hamsters. Parents pass these bacteria to the progeny through certain forms of their social behavior. The bacterial community forms in babies by the 20th day, i.e. when they are abandoned by parents and start independent existence. A composition of the bacterial community in the AS secrete is independent of the host sex; however, it depends on the physiological state of the host organism, e.g. it changes during lactation. A removal of the AS secrete, containing bacteria, has adverse effects on the hamster physiology: it causes intestine dysbacteriosis, active propagation of Protozoa and parasitic worms. The lack of a normal microbial community in the AS of babies, who did not get the AS secrete from their parents, has analogous consequences.
