Six-Hundred Year-Old Petrified Poop Contains Antibiotic Resistance Genes

Once you get over the shock of a perfectly preserved 14th century turd (Dude, what did you eat?), the story is actually pretty interesting: Scientists examining a six hundred year-old piece of human poop have discovered the presence of genes that provide antibiotic resistance.

Via Heritage Daily:

A team of French investigators has discovered viruses containing genes for antibiotic resistance in a fossilized fecal sample from 14th century Belgium, long before antibiotics were used in medicine.

The viruses in the fecal sample are phages, which are viruses that infect bacteria, rather than infecting eukaryotic organisms such as animals, plants, and fungi. Most of the viral sequences the researchers found in the ancient coprolite (fossil fecal sample) were related to viruses currently known to infect bacteria commonly found in stools (and hence, in the human gastrointestinal tract), including both bacteria that live harmlessly, and even helpfully in the human gut, and human pathogens, says corresponding author Christelle Desnues of Aix Marseille Université.

The communities of phage within the coprolite were different, taxonomically, from communities seen within modern human fecal samples, but the functions they carry out appear to be conserved, says Desnues. That reinforces the hypothesis that the viral community plays a fundamental role within the human gastrointestinal tract, and one which remains unchanged after centuries, even while the human diet and other human conditions have been changing.

    If you check out the article, there’s a really col pic of the turd in question. LOL

      Sorry to disappoint you, but the article states the turd in the picture is not the antibiotic resistant turd, but rather something referred to as the Lloyds Bank turd. Never knew ancient turds were a thing though.

            love it! thanks for the petriscatological adventure.

        I guess I have once again proved that I don’t know shit. I am also amazed that there are scientists dedicated to this study.

    that’s some good shit man!
