Schistosomiasis remains a major parasitic disease, endemic in large parts of South America. Five neotropical species of Biomphalaria have been found to act as intermediate hosts of Schistosoma mansoni in natural populations, while others have been shown to be susceptible in experimental infections, although not found infected in the field. Among these potential intermediate hosts, Biomphalaria ...

The faba bean (Vicia L.) is cultivated in the Mediterranean and Aegean regions only. It a rich source of protein an important food feed for human animal consumption. Faba beans have narrow genetic base their improvement through hybridization not feasible because high pollen self-incompatibility. This study was carried out using embryonic axis cv. Filiz99 Eresen87 regenerated on MS medium contai...

Pricking the body wall of Sarcophaga peregrina (flesh fly) larvae with a needle activated the immune system of this insect and induced various immune molecules, including antibacterial proteins, in the hemolymph. In this review, I summarize and discuss the functions of these immune molecules, with particular emphasis on the dual roles of some of these molecules in defense and development.

In Bodega Harbor, California, the nemertean Paranemertes peregrina spawns in June or July. Adults in the study area were small in comparison to worms found on two Washington mud flats. Population density of active worms averaged 7.38 worms/m 2 , with much variation due to time of day of low tides. Approximately 28 percent of the active population ate during the low tide periods that were sample...
