Slugs and snails specifically secrete mucus to aid their locomotion. This mucus is the contact material between molluscan herbivores and plants. We have recently shown that the locomotion mucus of the slug Deroceras reticulatum contains salicylic acid (SA).(1) When applied to wounded leaves of Arabidopsis thaliana this mucus induces the activity of the SA-responsive pathogenesis related 1 (PR1)...

The ability of slugs (Deroceras reticulatum) to survive exposure to various chemical stressors such as molluscicides (carbamates, metaldehyde, iron-chelates) or other environmental pollutants (heavy metals, pesticides) was investigated using x-ray analyses, autoradiography, filter electron rnicroscopy, enzyme histochemistry, enzymatics, electron microscopy, and stress protein analyses. Uptake p...

UNLABELLED The urbanization process of schistosomiasis has been described in the literature. The present report shows and discusses some epidemiological aspects of neuroschistosomiasis that emphasizes this trend. METHOD The study was done between July, 2005 and June, 2006, and consisted of spinal cord schistosomiasis carriers at the moment of diagnosis. These patients were evaluated whatever ...

OBJECTIVE To assess the magnitude, geographical distribution and trends of the prevalence of nutritional anemia among preschoolers and to identify risk groups in the state of Paraiba, Brazil. METHODS A cross-sectional survey with multistage random sampling procedure was conducted in 8 urban municipalities of three mid-regions (Zona da Mata, Agreste and Sertão) in the state of Paraíba in 1992....

New and little-known terrestrial slugs are dealt with based on extensive collections made in East Africa (Kenya, Tanzania, and Uganda) 1993-2007. This account deals primarily with larger species from forests in the Eastern Arc Mountains of Tanzania. In Veronicellidae, Pseudoveronicella Germain, 1908 is extended to Tanzania by P. (Hoffmannia) zootoca tanzaniensis subsp. n. in the Udzungwa Mts. I...

Natural products are usually used as a food source for the culture of terrestrial molluscs. Better uniformity, and perhaps economy, could be introduced to the culture of molluscs by using synthetic diets. I assessed acceptance by various terrestrial molluscs of several insect diets developed for culture of caterpillars, and suitability for mollusc growth. Diet selection (preference) studies wer...
