Oldest nanomachines in biology is the bacterial flagellum

One of the oldest nanomachines in biology is the bacterial flagellum. This apparatus is evolutionary essential, endowing onto bacteria the ability to move. The flagellum shares high similarity with another bacterial structure, the injectisome, which as the name implies is how some bacteria deliver their content to infect a host. …

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 …

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 …
