The Bubonic plague slowed urbanisation, industrial development and economic growth in Europe for many years.
Despite being so small they can't be seen with the naked eye, pathogens that cause human disease have greatly affected the way humans live for centuries.
Just as organisms that infect us make changes in us - we too make changes in them and they grow and adapt to their human hosts.
Humans play host to many little passengers. Right now, you’re incubating, shedding or have already been colonised by viral, bacterial, parasitic or fungal microorganisms - perhaps even all of them.
The Vespula germanica, or German wasp, is an invasive species in South Africa.

Indigenous biocontrol agents could be used to curb the spread of invasive wasps across South Africa and into sub-Saharan Africa.
From turkeys to salmon and brussels sprouts, modern living is putting mounting pressure on the festive feast.
Facing down a future with no bananas.
Every single Cavendish banana plant worldwide is genetically identical. This vast monoculture sets them up for disastrous disease outbreaks. But researchers have ideas on how to protect the crop.
Goldfish might look nice, but they can also spread a variety of decidedly not-nice viruses.
Many pet fish end up in ponds, fountains and waterways. But before ditching your goldfish in the park, stop and think about the viruses you could also be releasing.
The pathogens are secured, but are the data about them as well-protected?
Biosafety needs to be about more than personal protective equipment and safe laboratory practices. Don't forget the cybersecurity.

Vaccines aren't just for animals anymore. Research shows priming plants with pathogen-derived compounds strengthens their immune systems and enhances protection against future attack.
