NewsResearch finds key connection between Legionnaires disease and ‘host’ amoeba
A new study of domestic and hospital drinking water systems found Legionella in 41% of samples – with Flinders University researchers making a key connection between the pathogen’s co-existence with a ‘host’ microorganism in all samples tested.

NewsCRISPR self-destruct protein may yield new tests for many viruses
A recently discovered protein has been found to act as a kind of multipurpose self-destruct system for bacteria, capable of degrading single-stranded RNA, single-stranded DNA and double-stranded DNA and holding potential for the development of at-home diagnostic tests for a wide range of infectious diseases.

NewsBacteria with anti-inflammatory effects found in gut of sclerosis patients with no evidence of active disease
Multiple sclerosis patients do not have the same bacteria in their intestines as healthy people. There are also differences in the composition and function of the bacteria in the intestines of multiple sclerosis patients, depending on whether their illness is active, and whether they are in treatment, a new study shows.
