PcLys-i3, an invertebrate lysozyme, is involved in the antibacterial immunity of the red swamp crayfish, Procambarus clarkii.

Antimicrobial peptides (AMPs) play important roles in innate immunity against pathogens and lysozymes are a particularly type of AMP. Lysozymes are hydrolytic enzymes that are characterized by their ability to cleave the beta-(1,4)-glycosidic bond between N-acetylmuramic acid and N-acetylglucosamine in peptidoglycan, which is the major bacterial cell wall polymer. In this work, a lysozyme was identified from Procambarus clarkii and designated PcLys-i3.

Involvement of aurantiactinomyxon in the life cycle of Thelohanellus testudineus (Cnidaria: Myxosporea) from allogynogenetic gibel carp Carassius auratus gibelio, with morphological, ultrastructural, and molecular analysis.

During the investigation of actinosporean fauna diversity from commercial fish ponds in Hubei Province, China, a novel aurantiactinomyxon type was found from Branchiura sowerbyi. Spore body of the aurantiactinomyxon was ellipsoidal in side view and triangular in apical view, 15.5 ± 0.
