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

One time I was watching a football game on TV and they had a short quiz, called “You make the call” or something like that, and you had to watch a play and pretend to be a referee. A short video clip showed football players falling over each other. Then you were three possible calls…

Blogging from the NW ASM branch meeting, part II Yesterday, I wrote about the some of present (and future) methods that are (or will be) used in clinical labs to identify pathogenic microbes. In these next two posts, I want to describe the talks I attended on antibiotic resistance, from Xuan Qin and Fred Tenover…

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

This is the fifth part of a multipart series on antibiotic resistance in bacteria. The previous installments: 1. A primer on antibiotic resistance: an introduction to the question of antibiotic resistance. 2. Natural vs. synthetic drugs: what is the difference between an antibiotics and synthetic drugs. 3. How do antibiotics kill bacteria? a general discussion…

After reading Kevin C.’s question in the comments on my last antibiotic post, I decided to look into this question a bit further. As far as I can tell, most of the commercially producted antibiotics are made by bacteria, fungi, and a bit chemistry (more on that in a moment). It appears, however, that compounds…

This is multipart series on antibiotic resistance in bacteria. Check out the previous bits: 1. A primer on antibiotic resistance 2. Natural vs. synthetic drugs Eventually, we’ll reach the ways in which bacteria develop antibiotic resistance, but before we get there, we’ll spend a little more time on antibiotics themselves.

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.

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…

A few years ago, I heard an interesting thing from another mother when I picked my oldest daughter up from daycare. The other mother was suffering from a head cold and confessed to me her fear that she had become “antibiotic resistant.” I found this statement pretty funny at the time, especially since I was…
