Gut-Brain-Axis imbalance due to gut dysbiosis by antibiotics may lead to neurobehavioral changes. Here we determine neuroprotective effect of probiotic against gut dysbiosis associated decline in learning and memory. Oral Ampicillin was used to induce gut dysbiosis while probiotic was administered along with antibiotic as treatment in Swiss albino mice. Antibiotic decreased Lactobacillus, Bifidobacterium, Firmicutes and Clostridium level. This was followed by reduced cognition, hippocampal neuronal density, intestinal crypt depth, villus length and increased corticohippocampal acetylcholinesterase, myeloperoxidase activity and oxidative stress which were partially reversed by probiotic treatment. Probiotic protected hippocampal neurons from gut dysbiosis associated inflammatory and oxidative damage in mice.
