Toxoplasma gondii is a microbial parasite often carried by cats, and passed on through contaminated water and faeces. It infects almost all warm blooded animals. In humans this microbe is usually kept in check by the gut microbial community, which out-compete it. However if the gut bacterial community is not functioning normally, toxoplasmolysis may result. In rats and mice, the pathogen can pass into the blood stream and migrate to the brain, where it induces behavioural changes. Infected mice no longer recognise cats (or their odour) as dangerous, which provokes them to put themselves at risk. When a cat eats an infected rat, this spreads the pathogen to a new host.

However his words resonated far beyond their intended audience, awakening a worldwide movement for racial emancipation and human equality which still continues today (Image: Dick DeMarsico, World Telegram staff photographer/Wikimedia Commons)
