Haemophilus influenzae bacteria attaching to a surface as seen by a scanning electron microscope. Researchers from the University of Southern California (USC) and the Oak Crest Institute of Science, both in Pasadena, Calif, have discovered the link between antibiotics and bacterial biofilm formation leading to chronic lung, sinus and ear infections. During the study, non-typeable Haemophilus influenza (NTHi) bacteria, a common pathogen of humans, was exposed to non-lethal doses of ampicillin, a class of antibiotics commonly used to treat respiratory, sinus and ear infections, or other beta-lactam antibiotics. Biofilms are highly structured communities of microorganisms that attach to one another and to surfaces. Dr Webster believes modern medicine needs to find ways of detecting and treating biofilm infections before the bacteria are able to form these protective structures.  The difficulties of treating biofilm infections, which can be up to 1,000 times more resistant to antibiotics, have prompted some physicians to propose a gradual move away from traditional antibiotic treatments and toward non-antibiotic therapies.


Content from the Daily Telegraph and Sunday Telegraph newspapers and video from Telegraph TV. The study results, published in the July 9 edition of PLOS ONE, illustrate how bacterial biofilms can actually thrive, rather than decrease, when given low doses of antibiotics. The dose of the antibiotic was not enough to kill the bacteria, which allowed the bacteria to react to the antibiotic by producing glycogen to produce stronger biofilms when grown in the laboratory.
Therefore, bacteria forced into forming stronger biofilms will become more difficult to treat and will cause more severe chronic infections. This layer is highly protective for the organisms within it, and when new bacteria are produced they stay within the slimy layer.
Adults will suffer protracted lung infections as the bacteria hunker down into their protective slime, and children will have repeated ear infections.


With the introduction of antibiotic-produced glycogen, the biofilms have an almost endless food source that can be used once antibiotic exposure has ended. What may appear to be antibiotic resistance when an infection does not clear up may actually be biofilms at work.
For example, a lung abscess may form following a bout of pneumonia; a brain abscess may form after a penetrating head wound (an injury in which the outer covering of the brain is pierced), etc.
For a skin abscess, this involves a small operation to cut the top of the skin and allow the pus to drain.
