Antibacterial immune response in Astacus leptodactylus (Crustacea, Decapoda).

open access: yesIn vivo (Athens, Greece), 1997
Antibacterial substances (ABS) in the hemolymph of Astacus leptodactylus were studied by agar-plate lysis and inhibition tests. The results demonstrate ABS against Gram-positive and Gram-negative bacteria. ABS against Gram-positive bacteria were identified as a lysozyme with a molecular weight of 14 kDa, heat resistance (< 50 degrees C) and lability to
