Research presented at American Society of Cell Biology's 50th annual meeting in Philadelphia The protozoan parasite Toxoplasma gondii and the pathogenic bacterium Chlamydia trachomatis exemplify convergent evolution, the development of a similar biological trait in unrelated lineages, according to research presented today at the American Society of Cell Biology's 50th Annual Meeting in Philadelphia. The biological trait shared by the two pathogens is their modus operandi "“ how they...

Press release from PLoS Medicine Prenatal treatment of congenital toxoplasmosis with antibiotics might substantially reduce the proportion of infected fetuses that develop serious neurological sequelae (brain damage, epilepsy, deafness, blindness, or developmental problems) or die, and could be particularly effective in fetuses whose mothers acquired Toxoplasma gondii, the parasite that causes toxoplasmosis, during the first third of pregnancy. These are the findings of an observational study...

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. In the study, Rima McLeod and colleagues point out that toxoplasmosis is one of the world's most common...

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. The protein, calcium dependent protein kinase 1 (CDPK1), is made by Toxoplasma gondii, the toxoplasmosis parasite; cryptosporidium, which causes diarrhea; plasmodium, which causes...

Team liberates cellular hostages by silencing Toxoplasma gondii's back-seat driving Scientists studying a cunning parasite that has commandeered the cells of almost half the world's human population have begun to zero in on the molecular signals that must be severed to free the organism's cellular hostages. While Toxoplasma gondii is not as widely known by the public as some of its more notorious parasitic brethren, it has been hijacking the cells of human and animal hosts for eons and is...

An international team led by researchers from the University of Cordoba (UCO) has analyzed seroprevalence (antibodies to a disease) of Toxoplasma Gondii, the parasite that causes toxoplasmosis in many species, including humans. This latest study reveals that the parasite is widespread in areas where the wild Iberian Lynx (Lynx pardinus) lives, and also in captive breeding centers. Scientists are now undertaking further research into the disease itself. Wild felids are important for...

In what's described as a genetic leap, U.S. researchers have discovered how to destroy a key DNA pathway in a widespread human parasite. Dartmouth Medical School scientists said their findings could help fast track vaccine and drug development to prevent or mitigate serious global diseases. They said their achievement surmounts a major hurdle for targeting genes in Toxoplasma gondii -- an infection model whose close relatives are responsible for diseases that include malaria and severe...

Turns model parasite into genetic workhorse-In a genetic leap that could help fast track vaccine and drug development to prevent or tame serious global diseases, DMS researchers have discovered how to destroy a key DNA pathway in a wily and widespread human parasite. The feat surmounts a major hurdle for targeting genes in Toxoplasma gondii, an infection model whose close relatives are responsible for diseases that include malaria and severe diarrhea."This opens a wide window on a complex...

Researchers at the University of Pennsylvania have discovered that parasites hijack host-cell proteins to ensure their survival and proliferation, suggesting new ways to control the diseases they cause. The study, appearing this week online in Science, was led by Doron Greenbaum, PhD, Assistant Professor of Pharmacology in the Penn School of Medicine."Researchers can now develop ways to kill parasites by placing roadblocks in the path they use to destroy their victims," says Greenbaum. The...

Scientists in the UK have reported the first evidence that links schizophrenia to toxoplasma parasites. People who become infected by toxoplasma may develop a minor illness called toxoplasmosis, which can become serious if it is passed from pregnant mother to child. Previous studies have suggested that toxoplasmosis can indirectly cause schizophrenia because of dopamine-blocking treatments like haloperidol. However, Dr. Glenn A. McConkey at the University of Leeds, told Reuters Health that...
