Research into naturally occurring antimicrobial substances has yielded effective treatments. One area of interest is peptides and proteins produced by invertebrates as part of their defence system, including the contents of mollusc mucus. Mucus produced by the African giant land snail, Achatina fulica has been reported to contain two proteins with broad-spectrum antibacterial activity. Mucus fr...
BACKGROUND The garden snail, Helix aspersa, is a big land snail widely found in the Mediterranean countries. It is one of the most consumed species and widely used in zootherapy. OBJECTIVE The present study was carried out to investigate for the first time the first time the antitumor activity of an aqueous extract from Helix aspersa. MATERIALS AND METHODS The effect of H. aspersa extract w...
The effect of clodinafop –propargyl against the mucus land snail, Helix aspersa, was studied under laboratory and field conditions during autumn 2020 season. Snails were exposed to serial concentrations clodinafop-propargyl for successive seven days using contact bait techniques. Median Lethal concentration (LC50) determined LC25 test compound examined on total protein alkaline phosphatase afte...
The aim of the present study was to examine the distribution of cells expressing connexin 26 (Cx26) in the suboesophageal visceral, left and right parietal and left and right pleural ganglia of the snail Helix aspersa by immunocytochemistry. Altogether we have found approximately 452 immunoreactive neurons which represent the 4.7% of the total neurons counted. The stained large neurons (measure...
Reproductive traits of the land snail Helix aspersa Müller were investigated under artificial conditions from two samples, one collected from a population exposed to unpredictable human pressures in its natural environment, i.e. a recently created polders area with intensive agriculture, and the other from a snail farm in which animals were reared under constant conditions defined as ‘optimal’ ...
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...
