“…In addition, the hemolymph consisted of many antimicrobial components (Fredrick and Ravichandran, 2012). However, the colonized bacteria do not induce septicemia, and the host does not kill the bacteria.…”

“…The hemolymph microbiota coexists with hemocytes and antimicrobial components, both of which have important roles in direct phagocytosis and eradication of bacteria (Fredrick and Ravichandran, 2012;Jiravanichpaisal et al, 2006). In addition, given that the crustaceans harbor open circulatory system, the microbiota and hemolymph spread through the entire body to confront immune defenses from other organs (McMahon, 2001).…”

“…The purification and characterization of the new AMPs in marine organisms are important in order to find new solution to the existence of bacterial resistances towards conventional antibiotics [51]. Recently, the antibacterial activities of mud crab from the genus Scylla have been intensively studied and reported in many researches [42,47,[51][52][53]. Furthermore, [45] in supporting the antimicrobial activity in mud crab from earlier studies, Hoq et al [52] have partially purified the antimicrobial protein from the induced hemolymph of S. serrata.…”

“…Furthermore, [45] in supporting the antimicrobial activity in mud crab from earlier studies, Hoq et al [52] have partially purified the antimicrobial protein from the induced hemolymph of S. serrata. In this case, hemolymph refers to a fluid that circulates in the interior parts of crabs [53], with copper containing hemocyanins as the major protein component of hemolymph in crustaceans. In a more recent study, the humoral immune function of hemocyanins that has been isolated from the serum of mud crab, S. serrata was characterized by Velayutham and Munusamy [42].…”

Mud crab from the genus Scylla is also known as mangrove crab, which has been well-accepted as a good source of protein.Recently, the antioxidant properties present in mud crabs have been reported to have a part in the protection of cells against free radicals. Meanwhile, numerous antimicrobial peptides from mud crabs have managed to be characterized through the display of antimicrobial activities against Gram-positive and Gram-negative bacteria. Hence, this paper is an effort to collect recent literatures on antioxidant and antimicrobial properties in every part of mud crabs which include muscle tissue, hemolymph, and crab shell. Moreover, the effort to understand the biological properties of mud crabs is important to enhance its production in aquaculture industry. Therefore, this review hoped to attract the attention of natural product researchers to focus on the potential therapeutic applications of mud crabs.

“…A third potential mechanism is to have physiological resistance to injected venom, which could be obtained through mutations of target proteins making them resistant to the venomous molecules (Barchan et al 1992, Voss & Jansa 2012. Defensive molecules in hemolymph (Fredrick & Ravichandran 2012) might play a role to neutralize the venom. To explore these hypotheses of possible mechanisms of phyllosomas tolerance to jellyfish venom, we examined if: (1) nematocysts of Japanese sea nettle Chrysaora pacifica (Goette, 1886) in the feces of phyllosomas are discharged; (2) if nematocysts in the feces are surrounded by peritrophic membrane; and (3) if phyllosomas are tolerant to crude extract from venom of the rhizostome jellyfish Nemopilema nomurai Kishinouye, 1922.…”

Jellyfish possess venomous cnidae on their tentacles to capture and consume marine zooplankton. Nevertheless, the planktonic larvae of the smooth fan lobster (Ibacus novemdentatus), known as phyllosoma, prey on jellyfish and successfully ingest both tentacle tissue as well as constituent cnidae, despite the presence of the venom-filled explosively penetrant cnidae or nematocysts. In the present study, we hypothesized that phyllosomas have mechanical and/or physiological resistance to internal envenomation by ingested nematocysts. To test this hypothesis, we examined the feces of phyllosomas (n=5) that were fed with Japanese sea nettle (Chrysaora pacifica) and found both undischarged as well as discharged cnidae surrounded by peritrophic membrane. We surmise that this membrane may mechanically insulate the lining of the midgut from stinging nematocysts to avoid injection of jellyfish venom into the phyllosomas body by nematocyst tubule penetration. We then tested physiological sensitivity of the phyllosomas (n=10) to crude extract of tentacle cnidae injected into their bodies. For this experiment, we used a crude venom extract prepared from nematocysts isolated from tentacles of a rhizostome jellyfish (Nemopilema nomurai) after exposure to high salt which disrupted tentacle integrity, and phosphate-buffered saline as a control. Nine out of 10 animals died after the injection of crude venom extract, while none of the animals died in the control group. These results indicate that the defense of phyllosoma larvae against the toxin of jellyfish is a combination of mechanical inactivation of the ingested nematocysts and chemical digestion of the toxin in the midgut rather than physiological resistance against the toxin.
