A recent report goes a long way towards dispelling the notion that "nanobacteria" found in human blood are living entities. They seem to be inorganic precipitates, instead. Fine with me. What is less fine is that those making the original claim have mangled a perfectly good term and perhaps rendered it useless. Many, if not most, bacteria in the environment are very small, some passing through filters that retain "regular" bacteria. See our previous post entitled Old, small, cold… or a most informative review. These tiny organisms deserve to be called nanobacteria. This may be a lost cause. When entering "nanobacteria" in Google, the first 100 hits (out of 186,000) are about the apparently spurious entities, none about real bacteria. Abuse of words happens.
