Gut dysbiosis in animal models is primarily characterized by an elevated ratio of Firmicutes/Bacteroidetes which may lead to the accumulation of amyloid precursor protein (APP) in the intestine, in the early stages of AD.

The study discusses a possible relationship between the oropharyngeal microbiome and schizophrenia. According to recent studies, the oropharyngeal microbiome may alter the immune system in the human body and cause various psychiatric disorders, including schizophrenia. The oropharyngeal microbiome can cause schizophrenia either by affecting the genes, chromosomes, and immune system in the human body. Additionally, it examines the combined mechanism of how the oropharyngeal microbiome's alterations lead to genetic abnormalities and immune dysregulation in schizophrenia.
