Novel delivery system devised for toxoplasmosis treatment

A new delivery system uses short chains of arginine to ferry drugs across membranes and into cysts of Toxoplasma gondii, a single-celled microorganism that causes toxoplasmosis. The discovery opens the possibility of treating active and latent infections in the eye by applying a lotion containing triclosan.

Potato-related plant species exhaust potato cyst nematode

Researchers have discovered that Solanum sisymbriifolium can eliminate potato cyst nematodes from the soil, which are difficult to control. By cultivating this plant between potato harvests, farmers may be able to reduce the need for pesticides and improve crop yields.
