    Digital Biology Friday: What sequences do you believe?

    During the past few Fridays (or least here and here), we've been looking at a paper that was published from China with some Β-lactamase sequences that were supposedly from Streptococcus pneumoniae. The amazing thing about these particular sequences is that Β-lactamase has never been seen in S. pneumoniae before, making this a rather significant (and possibly scary) discovery. If it's...

    Sometimes the sickest bacteria are the best survivors.

    Antibiotic resistance: taking the bypass

    The wind storms and heavy rains that hit Seattle recently, demonstrated why a bypass mechanism can be a helpful thing - for both bacteria and motorists. Under the bridge on Mercer, from the Seattle Times...

    Five paths to antibiotic resistance: a quick summary

    How do I resist thee? Let me count the ways.

    Are antibiotics really only made by bacteria and fungi?

    Antibiotics au naturale?

    What's the difference between a synthetic drug and an antibiotic? Sometimes there's no difference at all. Let's take a look at chloramphenicol and couple of pencillins....

    A primer on antibiotic resistance, part I: what are antibiotics?

    Antibiotics are molecules of biological warfare. Produced by bacteria and some fungi, in response to extracellular signals, antibiotics represent a diverse group of compounds that inhibit bacterial growth at different points and different stages of the life cycle. We will get around to antibiotic resistance, but in these few words, I think I already wrote quite a bit. Admittedly, some...
