“…Each has distinctive morphological features and physiological functions [28]. Haemocytes are responsible for clotting, exoskeleton hardening and elimination of foreign materials [27]. Mean THCs of healthy penaeid shrimps ranged from 20 to 40 Â 10 6 cells ml ÿ1 [20].…”

“…Results from several experiments have implied that apart from their role in melanisation, components of the putative proPO activating system stimulate several cellular defence reactions, including phagocytosis, nodule formation, encapsulation, and haemocyte locomotion [5]. Activated haemocytes also produce extra bactericidal substances, such as H 2 O 2 and superoxide anion (O 2 ÿ ) that may increase disease resistance [27].…”

“…During phagocytosis, reactive oxygen species are produced. This phenomenon, known as respiratory burst, plays an important role in microbicidal activity [13]. Because O 2 ÿ is the first product released from a respiratory burst, O 2 ÿ measurement has been accepted as an accurate method for estimating the cell's capability to generate a respiratory burst [13,15].…”

“…The production of superoxide anion known as respiratory burst plays an important role in microbicidal activity [12]. Song and Hsieh [13] first demonstrated a respiratory burst in Penaeus monodon haemocytes. It has been reported in haemocytes of Penaeus stylirostris [14], Penaeus vannamei [15], Macrobrachium rosenbergii [16] and Litopenaeus vannamei [17].…”

An enzyme with similarities to myeloperoxidase, the antimicrobial halide peroxidase in mammalian neutrophils, occurs abundantly in the light organ tissue of Euprymna scolopes, a squid that maintains a beneficial association with the luminous bacterium Vibrio fischeri. Using three independent assays typically applied to the analysis of halide peroxidase enzymes, we directly compared the activity of the squid enzyme with that of human myeloperoxidase. One of these methods, the diethanolamine assay, confirmed that the squid peroxidase requires halide ions for its activity. The identification of a halide peroxidase in a cooperative bacterial association suggested that this type of enzyme can function not only to control pathogens, but also to modulate the interactions of host animals with their beneficial partners. To determine whether the squid peroxidase functions under both circumstances, we examined its distribution in a variety of host tissues, including those that typically interact with bacteria and those that do not. Tissues interacting with bacteria included those that have specific cooperative associations with bacteria (i.e., the light organ and accessory nidamental gland) and those that have transient nonspecific interactions with bacteria (i.e., the gills, which clear the cephalopod circulatory system of invading microorganisms). These bacteria-associated tissues were compared with the eye, digestive gland, white body, and ink-producing tissues, which do not typically interact directly with bacteria. Peroxidase enzyme assays, immunocytochemical localization, and DNA-RNA hybridizations showed that the halide-dependent peroxidase is consistently expressed in high concentration in tissues that interact bacteria. Elevated levels of the peroxidase were also found in the ink-producing tissues, which are known to have enzymatic pathways associated with antimicrobial activity. Taken together, these data suggest that the host uses a common biochemical response to the variety of types of associations that it forms with microorganisms.
