In part 1, I looked at Bifidobacterium bifidum to see if the occasionally observed Y-shape of these bacteria gives any hint on their mode of cell division ─ maybe longitudinal division? No, there is no tang...

Don't worry, STC won't switch to cuneiform without warning. What vaguely resembles a chemical formula or a cuneiform text is meant to keep the title as short as possible. More verbose: I will take a closer loo...
With kind permission by the organizers, we reproduce here Elio's message to the attendees of the meeting on 'Major ideas in quantitative microbial physiology: Past, Present and Future' held in June this year in København, Denmark.

As we speak, biofilms are the rage in microbiology. And why not, being that most bacteria in nature are not free-swimming but are attached to some surface. Model systems for biofilms are therefore sorely ne...

I have studied bacterial biofilms since I joined Roberto Kolter's lab at Harvard Medical School in 1995. I "discovered" biofilms as I was finishing my graduate work at Wisconsin and continued tracking the literature...

Imagine the E. coli nucleoid as a swig but of a highly viscous tangle of a 2 nm thin and ~1.5 mm long DNA polymer, decorated with and highly compacted by a plethora of proteins, and somehow suspended in the cytoplasm of a ...

In ancient times, persons suffering from a dreaded disease believed to be contagious, such as leprosy, were given a bell to ring and thus noisily announce their presence. Healthy people could ...
