Genome structure of malaria parasites linked to virulence

An international research team led by scientists at the University of California, Riverside, and the La Jolla Institute for Immunology has found that malaria parasite genomes are shaped by parasite-specific gene families, ...

Researchers develop model of toxoplasmosis evolution

Toxoplasmosis is an infectious disease caused by the spread of Toxoplasma gondii, a parasitic alveolite with an interesting life cycle. It exists in three forms. First, oocysts are produced in cats and passed in feces or ...

A new twist on how parasites invade host cells

Toxoplasmosis is a widespread infection caused by the parasite Toxoplasma gondii, which multiplies within a host and irreversible tissue damage. Humans primarily become infected by eating undercooked meat and poorly washed ...

Scientists reveal how immune system tags Toxoplasma capsule

Scientists at the Francis Crick Institute have discovered how the host immune system deals with the prolific Toxoplasma parasite as it attempts to camouflage itself by hiding inside a capsule called a vacuole in human cells.

What makes Toxoplasma gondii so unpredictable?

Toxoplasma gondii is a common parasite often spread by cats. Most people who are infected in Europe or North America show no symptoms at all, and only a few suffer from encephalitis or ocular toxoplasmosis, which can cause ...

Cat parasite found in western Arctic Beluga deemed infectious

University of British Columbia scientists have found for the first time an infectious form of the cat parasite Toxoplasma gondii in western Arctic Beluga, prompting a health advisory to the Inuit people who eat whale meat.

How mice survive infection by virulent Toxoplasma parasites

One of the commonest parasites in the world is Toxoplasma gondii. Toxoplasma can infect most warm-blooded animals, including humans, and causes significant damage to the unborn child if a woman becomes infected for the first ...

Otters show disease could be in our rivers

For the first time scientists have shown that the disease Toxoplasmosis is widespread in animals found in the UK's water systems. If the disease is common in our rivers it could mean that humans are at a high risk of infection.
