First discovered in the early 1900s, by French bacteriologist Charles Nicolle and his collaborator Louis Manceaux, Toxoplasma gondii is a microscopic species of parasitic protozoa in the genus Toxoplasma, that causes an infection called toxoplasmosis – one of the most common parasitic diseases worldwide, found in almost all warm-blooded animals (e.g. cats, mice and other rodents) and humans. A new Danish study has shown a connection between the cat parasite and suicide attempts in humans, especially in pregnant women.
