Infectious disease

Eleven years ago, two scientists made a bet. One scientist wagered that a new type of antimicrobial agent, called antimicrobial peptides, would not elicit resistance from bacterial populations which were treated with the drugs. Antimicrobial peptides are short proteins (typically 15-50 amino acids in length) that are often positively charged. They are also a part of our…

After this post on antibiotic resistance, many of you may have seen an exchange on Twitter calling me out for being “knee-jerk” about my call to action to do something about the overuse of antibiotics. In that post, I focused on antibiotic use in agriculture, giving only brief mention to human clinical use. There are…

Superbugs rising

It’s a parent’s worst nightmare. Your healthy child is suddenly ill. The doctors you’ve trusted to treat him are unable to do anything about it. Drugs that we’ve relied upon for decades are becoming increasingly useless as bacteria evolve resistance to them. New drugs are few and far between. Old drugs, shelved because of their toxic…

Guest post by Jessica Parsons. In November 2013 my son, Finn, was diagnosed at 3 months old with Ewing Sarcoma. The news that your child has a potentially life threatening disease at the beginning of their life is something that no parent is prepared for. Despite the scary news, he has completed 9 of the 14…

Why I vaccinate my kids

Being a new parent is exhausting. All of a sudden, you’re out of the hospital and on your own with this amazing, tiny human, and you alone are responsible for her care. You’re given reams of paperwork about feeding and sleeping, developmental milestones, red flags to look out for. You’re inundated with information you barely…

Guest post by Tim Fothergill, Ph.D. In January of this year the British Chief Medical Officer urged her government to add  threat posed by superbugs to the official list of “Apocalypses to Worry About” along with catastrophic terrorist attacks and massive flooding. With typical British understatement, its actual name is the National Risk Register of Civil…

The Microbiology of Zombies series

Part I: the microbiology of zombies Part II: ineffective treatments and how not to survive the apocalypse Part III: “We’re all infected” Part IV: hidden infections Part V: beware the bite?

New article on human-animal infections

Have a new article up today on Medscape (free registration required) on human-animal infections: a primer for clinicians. 

Now that seemingly the flu outbreak storyline has been wrapped up on The Walking Dead (unsurprisingly, but disappointingly, with their ineffective treatments proving to be miracle cures), there’s still one more zombie microbiology topic I’d like to cover: what’s up with the bite, and is it the cause of death? I said previously: “We know the pathogen…

(As previously, spoilers abound) So on this week’s Walking Dead soap opera, we find that Daryl/Michonne’s group is still out and about searching for medical supplies. Back at the prison, the food situation is dire (apparently all the food stores were in the cell block where the infection broke out), so Rick and Carol head…
