Isolation and partial characterisation of four novel plasma lectins from the American lobster Homarus americanus.

Although numerous haemolymph-derived crustacean lectins are described, few have been reported for the American lobster Homarus americanus. In the present study, affinity chromatography was used to isolate and partially describe the carbohydrate affinity of four new lectins from H. americanus plasma.

Ulcerative enteritis in Homarus americanus: case report and molecular characterization of intestinal aerobic bacteria of apparently healthy lobsters in live storage.

An intermoult male American lobster, Homarus americanus, with severe intestinal lesions was encountered while collecting samples of aerobic intestinal bacteria from lobsters held in an artificial sea-water recirculation aquarium system. Grossly, the intestine was firm, thickened, and white. Histologic examination revealed a severe, diffuse, ulcerative enteritis which spared the chitin-lined colon, somewhat similar to hemocytic enteritis of shrimp.

Isolation and characterisation of two antimicrobial peptides from haemocytes of the American lobster Homarus americanus.

Two antimicrobial peptides from haemocytes of the American lobster, Homarus americanus H. Milne Edwards 1837, were isolated and partially characterised - the first such description for this species. CAP-2, an approximately 12kDa peptide, contained amino acid sequences corresponding to the predicted sequence for Hoa-crustin.
