Biologist shows why some strains are more dangerous than others About one-third of the human population is infected with a parasite called Toxoplasma gondii, but most of them don't know it. Though Toxoplasma causes no symptoms in most people, it can be harmful to individuals with suppressed immune systems, and to fetuses whose mothers become infected during pregnancy. Toxoplasma spores are found in dirt and easily infect farm animals such as cows, sheep, pigs and chickens. Humans can be...

By Michael Purdy, Washington University in St. Louis 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. In a study published in Cell Host & Microbe, scientists show that the ROP18 protein disables host cell proteins that would otherwise...

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...

The Hong Kong flu pandemic was responsible for more than 700,000 deaths worldwide in the late 1960s, with major disease outbreaks in Europe in the winter of 1969-1970. A number of studies have been conducted to determine if prenatal exposure to the influenza virus may result in mental disorders that affect a small portion of the population, but no studies have explored the possible effects of prenatal exposure on the mean intelligence in the general population. A new study found that early...

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...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
