Antibacterial and antifungal lysozyme-type activity in Cameraria ohridella pupae

Activity and immunodetection of lysozyme in earthworm Dendrobaena veneta (Annelida)

“…Lysozyme with similar molecular mass of 20 kDa was purified from sponge Suberites domuncula (Thakur et al, 2005). In the insect Cameraria ohridella antibody directed against hen egg white lysozyme recognized protein with the mass of 28 kDa, apart from the protein of 15 kDa, both in the pupae extract and gut bacteria (Fiołka et al, 2005). These results suggest that lysozymes can possess different molecular mass depending on their source and the role in the organismhost defense or digestion.…”

“…Roch and collaborators (1991) discovered that the cell-free coelomic fluid of E. fetida inhibited in vitro growth of bacteria that are pathogenic for earthworm such as Bacillus megaterium and Aeromonas hydrophila. The antibacterial action against B. megaterium is also characteristic for lysozyme activity (Anderson and Beaven, 2001;Fiołka et al, 2005).…”

Antibacterial activity of lysozyme in the desert locust, Schistocerca gregaria (Orthoptera: Acrididae)

“…They hydrolyze the -1,4-linkages of chitooligosaccharides in the fungal cell wall (Fiolka et al, 2005).…”

Immunosuppressive effect of cyclosporin A on insect humoral immune response

“…The activity of lysozyme-a naturally occurring protein in insect haemolymph, increases greatly during an immune response (Mohrig and Messner, 1968) . Lepidopteran insect lysozymes show antibacterial activity against Gram (+) as well as Gram (À) (Yu et al, 2002) and also against fungi (Fiolka et al, 2005). Lysozyme of G. mellonella haemolymph might recognize and bind the microbial cells of pathogens (Lee, 2003).…”
