A new exhibition is aiming to show the positive impact of bacteria.
Bacteria World at the Oxford University Museum of Natural History has 55 exhibits, including a 92ft (28m) long inflatable E.coli sculpture.
Director Paul Smith promised the exhibition would explore "our very intimate relationships with bacteria".
Specimens include leafcutter ants, leeches and vampire bats, which live symbiotically with bacteria.
On display will be geological fossils showing evidence of how bacteria oxygenated the Earth 2.4 billion years ago.
It includes items loaned by the Wellcome Collection, Yale Peabody Museum of Natural History, the Pitt Rivers Museum, and the Natural History Museum, London.
