Microbiology Mondays: Helicobacter pylori infects over 50% of the world’s population and has sophisticated motility and chemotaxis mechanisms to navigate the hostile environment of the human stomach, where it resides. A recent Journal of Bacteriology report used advanced microscopy techniques to visualize the novel structures of the H. pylori flagella apparatus (shown here), which may provide...

Believe it or not, there is a lot of similarity between the Star Wars saga and the battle that rages in AIDS patients with cryptococcal meningitis. Our guest bloggers highlight the ways that Cryptococcus neoformans titan cells act like the Death Star and our T cells act as part of the Rebel Alliance. What other analogies can be made in this coinfection scenario? [ Bit.ly Link ]

Do bacterial species really exist and why should we care?

The second part of the question is relative easy to answer; the first part is much more chal­leng­ing.

Defining bacterial species is not only an im­por­tant academic exercise but also has major practical con­se­quen­ces. For example, infectious disease diagnoses, re­gulations involving the transport of bacteria, and edu­ca­ting the...

A natural alternative to antibiotics is the use of bacteriophage to treat bacterial infections. A new mBio report describes 'superspreaders,' or phage that spread quickly through a large bacterial population.
