So as a general rule I don’t like to pick on published papers… mostly I prefer to pick on news stories, particularly of the germaphobic variety. That being said, occasionally I see a paper that just makes me think “why is that published?”.
One of my interests is the topic of antimicrobials and antibiotic resistance in the built environment, so when I saw the title “Effects of the biocides on the culturable house dust-borne bacterial compositions and diversities” it was enough to get me to read the paper. I’m glad that I’m at an institution with a subscription to this journal because I would have been pretty peeved if I paid money for this closed-access paper (note the lack of figures in this post… yet another sadness with closed-access papers)
Basically the authors took house dust (well, dormitory dust) and exposed it to three different biocides; copper sulfate, triclosan, and benzalkonium chloride. They also cultured isolates from the dust and grew them in the presence of these biocides.
And their findings?
-Biocides kill bacteria in culture, more so at higher concentrations.
-Biocides kill some bacteria more than others
-Further study is warranted
Erm… didn’t we know all that? This seems like a case where a bunch of PCoA plots, stacked bar charts, and stats are attempting to cover for the lack of an interesting experiment.
