bacterial infection could contribute to Alzheimer’s disease

Researchers in the UK have used DNA sequencing to examine bacteria in post-mortem brains from patients with Alzheimer’s disease. Their findings suggest increased bacterial populations and different proportions of specific bacteria in Alzheimer’s, compared with healthy brains. The findings may support evidence that bacterial infection and inflammation in the brain …

Treatments of drug-resistant bugs by using nanotechnology

Antibiotic resistance is a growing problem, especially among a type of bacteria that are classified as “Gram-negative.” These bacteria have two cell membranes, making it more difficult for drugs to penetrate and kill the cells. Researchers from MIT and other institutions are hoping to use nanotechnology to develop more targeted treatments …

The biofilm construction capabilities of nontypeable bacteria

The laboratory of Lauren Bakaletz, PhD, director, Center for Microbial Pathogenesis and vice president of basic sciences, The Research Institute at Nationwide Children’s, studied the biofilm construction capabilities of nontypeable Haemophilus influenzae (NTHI), a bacterium responsible for sinusitis, pneumonia, exacerbations of cystic fibrosis and COPD, bronchitis and ear infections. Biofilms …
