Molluscs
Figure 1. The ‘Kraken’ myth. Ancient tales repeatedly reported octopod-like sea-monsters attacking sea vessels. Indeed, octopuses may reach a maximum of 3 m body size, but the foundation of these ancient tales is based on giant squids (with ten rather than eight arms as depicted here) defending itself against its main predator, a sperm whale, rather than octopuses. Squids are known to leave suc...
متن کاملLysozymes in molluscs
Invertebrates lack antibody-mediated humoral immune systems; however, they are believed to possess efficient host defense mechanisms involving humoral defense molecules that are similar in function to antibodies. Lysozymes are a group of enzymes that cleave the glycosidic bonds between N-acetylmuramic acid and N-acetylglucosamine (two amino sugars) in the peptidoglycans that form bacterial cell...
متن کاملPerkinsosis in molluscs: A review
The genus Perkinsus includes protistan parasites infecting marine molluscs throughout the world, some of which are associated with mass mortalities. Life cycle involves vegetative proliferation within the host, by which a cell named trophozoite undergoes successive bipartitioning. Other stages have been observed in vitro or in vivo, depending on the species: hypnospore, zoosporangium and zoospo...
متن کاملSaxitoxin analysis in bivalve molluscs
Paralytic shellfish poisoning (PSP) is caused by consumption of a wide variety of shellfish which accumulated saxitoxins (STXs) from marine dinoflagellates (Alexandrium minutum, A. tamarense, Gymnodinium catenatum, Pyrodinium bahamense) and affect a wide variety of shellfish. There are about 20 saxitoxin analogs with closely related structures. A regulatory level of 0.8 mg/kg shellfish meat as ...
متن کاملTransplant rejection in terrestrial molluscs
To know whether or not molluscs are capable of recognizing tissue allo-antigens, dorsal skin-allografts were exchanged between adult terrestrial slug, Incilaria fruhstorferi. We succeeded for the first time in orthotopic transplantation of allografts and observed chronic rejection of allografts. Cellular changes in the rejection process continued over for 40 days. Two functional types of “effec...
