Toxoplasmosis News and Research

RSS

Toxoplasmosis is considered to be the third leading cause of death attributed to foodborne illness in the United States. More than 60 million men, women, and children in the U.S. carry the Toxoplasma parasite, but very few have symptoms because the immune system usually keeps the parasite from causing illness. However, women newly infected with Toxoplasma during pregnancy and anyone with a compromised immune system should be aware that toxoplasmosis can have severe consequences for them.

Toxoplasma gondii directly affects production of dopamine in brain

A research group from the University of Leeds has shown that infection by the brain parasite Toxoplasma gondii, found in 10-20 per cent of the UK's population, directly affects the production of dopamine, a key chemical messenger in the brain.

Researchers characterise protein complex linked to malaria and toxoplasmosis

Maryse Lebrun, Research Director at Inserm, and her fellow researchers at the Laboratoire Dynamique des interactions membranaires normales et pathologiques, have characterised a protein complex that allows the agents that cause malaria and toxoplasmosis to infect host cells.

VIDAS TOXO IgG Avidity assay to test for recent Toxoplasma gondii infection receives FDA clearance

On May 18, the U.S. Food and Drug Administration cleared the first test to help determine whether a pregnant woman or a person with swollen lymph nodes testing positive for toxoplasmosis, sometimes known as cat scratch disease, developed the infection within the past four months.

Recent releases in Global Health

A Lancet Infectious Diseases editorial describes the growing public concerns over a global rise in antimicrobial resistance. "Bearing in mind that our objective is to contain antibiotic resistance rather than eradicate it, several policies could be adopted to help guarantee a future for antibiotics," the editorial states, adding, "We need reliable data to tackle antibiotic resistance.

Study: Pseudokinases can play a crucial role in pathogen-based disease

Researchers from the University of Pittsburgh and Stanford University discovered that a supposedly inactive protein actually plays a crucial role in the ability of one the world's most prolific pathogens to cause disease, findings that suggest the possible role of similarly errant proteins in other diseases.

New findings help explain why toxoplasmosis causes serious disease

Providing clues into why the severity of a common parasitic infection can vary greatly from person to person, a new Johns Hopkins study shows that each one of three strains of the cat-borne parasite Toxoplasma gondii sets off a unique reaction in the nerve cells it invades.

Study reports ROP18 protein protects parasite in host cell

Researchers at Washington University School of Medicine in St. Louis have learned why changes in a single gene, ROP18, contribute substantially to dangerous forms of the parasite Toxoplasma gondii. The answer has likely moved science a step closer to new ways to beat Toxoplasma and many other parasites.

ASTMH recommends FDA to include neglected infections of poverty in orphan classification

Today, U.S. scientists committed to finding answers to reducing and eliminating what are known as neglected tropical diseases (NTDs) that plague the world's poorest people in developing countries, urged the FDA to include in its orphan classification the neglected infections of poverty that also affect Americans, and expressed support for stronger relationships with the FDA to ultimately halt these ancient scourges.

Antibacterial ingredient in soap becomes guiding light for future development of drugs for toxoplasmosis

The antibacterial ingredient in some soaps, toothpastes, odor-fighting socks, and even computer keyboards is pointing scientists toward a long-sought new treatment for a parasitic disease that affects almost two billion people. Their report on how triclosan became the guiding light for future development of drugs for toxoplasmosis appears in ACS' monthly Journal of Medicinal Chemistry.

Discovery could lead to new treatment methods for toxoplasmosis

The parasite responsible for toxoplasmosis requires a stress response system that helps it survive the move to infect new cells, Indiana University School of Medicine scientists have reported, a discovery that could lead to new treatments to control the disease.

New study shows CDPK1 controls toxoplasma's ability to secrete microneme proteins

Researchers at Washington University School of Medicine in St. Louis have identified a parasite protein that has all the makings of a microbial glass jaw: it's essential, it's vulnerable and humans have nothing like it, meaning scientists can take pharmacological swings at it with minimal fear of collateral damage.

MUHC's Henry C. Witelson Ocular Pathology Laboratory celebrates tenth anniversary

The Burnier International Ocular Pathology Society is holding a Scientific Colloquium in Montreal today to mark the tenth anniversary of the McGill University Health Centre's Henry C. Witelson Ocular Pathology Laboratory. The lab is an internationally reputed centre for the study and treatment of eye diseases and is leading a global network for the sharing of healthcare knowledge and expertise.

Immune system mouse models help study biology of T cells and their role in toxoplasmosis

Using T cells primed for the infectious disease toxoplasmosis, Whitehead Institute researchers have created novel mouse models of the immune system that more accurately reflect how immune cells actually respond to pathogens in their presence.

New article in Women's Health journal emphasizes the importance of early pregnancy detection

A new article published in the peer-reviewed journal Women's Health emphasizes the importance of early pregnancy detection. Using research conducted on behalf of Church & Dwight Co. Inc., the makers of First Response, the article reviews data that shows not all at-home pregnancy tests are created equal -First Response brand pregnancy tests are more sensitive and able to detect key variants of the pregnancy hormone better than other at home pregnancy tests.
