The Mucoproteins of the Snails, Helix Aspersa and Helix Pomatia

The problem of the structure of complex proteins containing carbohydrates in their molecule is still a subject of discussion. The fundamental questions which have been debated during the last decades and which have been the subject of many controversies are concerned with the nature of the carbohydrate group present in the molecule of these substances. Since the discovery of mucoproteins or muc...

The Evaporation of Water from Helix Aspersa

It is known that the activity of terrestrial pulmonates is connected in some way to the extensive and often rapid fluctuations in water content which are characteristic of these animals (Howes & Wells, 1934; Wells, 1944). The work of Hughes & Kerkut (1956) and Kerkut & Taylor (1956) has further shown that the activity of the pedal ganglion of slugs changes with the osmotic pressure of the bathi...

The cytology of the neurones of Helix aspersa.

The moroccan food snail, Helix aspersa, as a source of Salmonella.

A total of 270 samples, nine lots of 30 samples each, of imported Moroccan food snails was examined for the presence of Salmonella. Eighty-four samples (an overall incidence of 31.11%) and all nine lots contained Salmonella. No significant difference (P greater than 0.25) in the number of positive samples was observed by using either selenite cystine both or tetrathionate broth when the samples...
