Credit: Florida State University<\/figcaption><\/figure>\n<p>The research suggests that when antibiotics disrupt the gut, it can lead to issues not just in the gut but also in the brain. Using a preclinical mouse model, researchers showed that antibiotic exposure depletes gut bacterial diversity and causes microbiome imbalance, which promotes the proliferation of <em>K. pneumoniae<\/em> by creating a favorable niche.<\/p>\n<h4>Implications for Hospital-Acquired Infections and Alzheimer\u2019s Risk<\/h4>\n<p>When this happens, <em>K. pneumoniae<\/em> can move from the gut into the bloodstream by passing through the gut lining and eventually reach the brain, triggering neuroinflammation and neurocognitive impairment.<\/p>\n<p>The findings emphasize the potential risk hospital-acquired infections like <em>K. pneumoniae <\/em>may pose in the development of neurodegenerative diseases.<\/p>\n<p>\u201cHospital-acquired and septic infections are one of the risk factors that may increase the predispositions to future neuroinflammatory and neurocognitive impairments, especially in older adults,\u201d Nagpal said.<\/p>\n<p>The study highlights the need for innovative therapeutic approaches to combat the rising prevalence of Alzheimer\u2019s disease, in addition to existing amyloid and tau protein therapies.
