Bacterial Infections. The brain is protected from bacterial invasion from the environment by the skull, the dura, the arachnoid membrane, the pia, and the glia limitans, which is a dense mesh of astrocytic processes on the surface of the brain.Consequently, most bacterial infections spread to the brain by the bloodstream.acterial toxins cause neuronal apoptosis and cell wall lipopolysaccharide, released from bacteria, damages the blood brain barrier (BBB). Increased vascular permeability from BBB damage, in turn, causes cerebral edema, increased intracranial pressure, decreased cerebral perfusion, hypoxia, and neuronal necrosis.
