E. coli are Gram-negative rod-shaped bacteria that are part of the normal flora of the human gut. Some strains produce a toxin that causes severe diarrhoea & can be fatal, especially in the very young or elderly. Black-coloured mug featuring an illustration of Escherichia coli & some facts about it Printed on demand in the UK. UK shipping included. International shipping supplement. MODEL ORGANISMS Guinea pigs & lab rats are the stereotypical terms that come to mind when people think of labs & experiments & science. in actuality, neither of these animals are commonly used in science anymore, though a few decades ago they were the staples of animal experimentation. Today, scientists use a range of other organisms, collectively termed model organisms, to learn about biology. Model organisms tend to be ones that are both cheap, & easy to breed & maintain in a laboratory. Often these organisms take up little lab space, as well as having quick generation times & rapid life cycles. They offer simpler systems to study the mechanisms underlying processes in more complex creatures such as humans, & allow scientists to understand things that can’t be studied directly - like genetics or human diseases. This print contains the organisms: Ciona intestinalis, Escherichia coli, Saccharomyces cerevisae, Caenorhabditis elegans, Danio rerio, Peromyscus, Drosophila melanogaster, Mus musculus, Arabidopsis thaliana & Zea mays E.
