M. tuberculosis is the king of pathogens - it causes tuberculosis, a nasty lung infection that has been around for thousands of years. TB kills more people than any other infection and shows little intention of going away. What makes M. tuberculosis so clever is that it can survive in the host for sometimes decades, effectively hibernating and waiting for the immune system to become weakened. Something like 1/3 of the world is infected with this little guy, and its not just developing countries - the UK and the US have big problems too!

Impressed? An M. tuberculosis bacteria design is available on a range of products from SuperBug!

- Human poo is a mixture of undigested food and bacteria, alive and dead. We can get really ill if we ingest this bacteria, so humans have evolved to be revolted by the smell, meaning we usually avoid eating our own poo.
