Determination of the Bacteriostatic Activity of Glycophorin Preparations from Red Blood Cell (RBC) Membranes of Yellow Tail and Red Sea Bream

Main Article Content

Takahiko Aoki


Glycophorins (GPs) in red blood cell (RBC) membranes of carp (Cyprinus carpio L.) exhibit bacteriostatic activity against various gram-negative and gram-positive bacteria. To clarify the physiological activity of teleost fish GPs other than those from carp, we performed a sensitivity test using GP preparations from the RBC membranes of yellow tail and red sea bream. The sensitivity test for the growth of Micrococcus luteus was performed using the disc-plate method. These results suggested that the yellow tail and red sea bream GPs exhibit antibiotic activities.
