THURSDAY, May 19 (HealthDay News) -- A new test to detect
whether a toxoplasmosis infection has been acquired within the past
four months has been approved by the U.S. Food and Drug
The Vidas Toxo IgG Avidity Assay -- approved for people with a
toxoplasmosis infection confirmed by other methods -- can be used
to validate whether infection by the Toxoplasma gondii parasite is
less than four months old. Human antibodies triggered by the
parasite behave differently after four months than they do
Toxoplasmosis, sometimes called "cat scratch disease" can be
passed from mother to unborn child. The infection can cause
miscarriage, stillbirth or an abnormally sized fetal head. In the
child's later life, it can lead to vision loss, mental impairment
or seizures, the FDA said in a news release.
While exposure to cats and used cat litter are primary methods
of transmission, toxoplasmosis also can be transmitted by other
animals and birds. And the parasite can be acquired by eating raw
or undercooked meat. Typical warning signs among people include
swollen lymph nodes and flu-like symptoms, the FDA said.
The test is produced by bioMerieux Inc., based in Hazelwood,
