“…The semigranular haemocytes were reported to be the primary cells involved in the phagocytosis of foreign particles in shrimp (Bachere et al, 1995;Soderhall and Cerenius, 1992). Granular haemocytes were also reported to be capable of phagocytosing foreign material but with less frequency than the smaller ones (Hose and Martin, 1989).…”

“…However, granular cells have been proven to play a significant role in the shrimp defense system due to their antibacterial activity (Chisholm and Smith, 1995). The smallest and least numerous hyaline cells were also considered as phagocytes (Soderhall and Cerenius, 1992). It was reported that the immune system of Penaeus chinensis could apparently be activated by oral administration of immunodrugs derived from the land and marine plants (Wang et al, 1995).…”

Shrimp disease management using bioactive marine secondary metabolites (MSMs) was developed as a package of practice for the sustainable shrimp farming. Therefore, the effect of MSMs on the host defense factors of shrimp was evaluated in the present study. Findings indicated that Ulva diet significantly increase the defense factors such as haemogram, agglutination index, phagocytic rate, bacterial clearance and serum bactericidal activity of treated shrimps over the control group. Based on the gut bacterial load, Ulva diet was considered as proactive drug whereas Dendrilla diet was determined as a curative agent. D

“…The circulating haemocytes of crustaceans are an essential part of the immune system, and perform functions such as phagocytosis, encapsulation, and lysis of foreign cells and much research in the defensive role of haemocyte in crustacean is being conducted [26,40,43]. The results suggest total haemocyte count (THC) is a reliable indicator of stress in crustaceans [2,44] including in marron [5,6].…”

The present study examined the effect of simulated transport on marron, Cherax cainii, (Austin, 2002) after a 10 week feeding trial using basal diet or customised probiotic, Bacillus mycoides supplemented diet by measuring intestinal bacterial population, total haemocyte count (THC), bacteraemia, morbidity, dehydration and mortality.Packing steps followed the established standard packing method for live transportation of marron. Each treatment group consisted of six polystyrene boxes (65 × 30 × 40 cm 3 ), and each box contained 30 marron from each feeding group. The sealed boxes were placed on a trolley at room temperature to give the effect of transportation. Boxes were opened at 24 th and 48 th hour post simulated transport and marron from each treatment group were returned to the culture tank. After temperature acclimation, the marron were observed for mortality and samples were collected to assess marron health and immunity.The results demonstrated that no mortality was observed at 24 h of transport both in basal diet and probiotic diet fed marron, however at 48h of transport the survival of probiotic fed marron was significantly higher (100 ± 0.0%) compared to survival (93.3 ± 2.8%) of basal diet fed marron. The higher survival rate of probiotic fed marron was also sustained by superior health and immune status indicated by higher intestinal bacterial population, higher total haemocyte count and lower haemolymph bacteria (bacteraemia) level. In brief, supplementation with host origin customized probiotic B. mycoides significantly improved marron tolerance to a live transport stress test, which resulted in no mortality up to 48h of transport.

“…Some cells with immunoreactivity for both VP28 and WSH8 were observed in connective tissues of the gut of the shrimps intubated with either VP28 or IVP, which we presume to be phagocytic cells such as hyalinocytes [33,35] or semigranular haemocytes [36,37].…”

a b s t r a c tSeveral oral vaccination studies have been undertaken to evoke a better protection against white spot syndrome virus (WSSV), a major shrimp pathogen. Formalin-inactivated virus and WSSV envelope protein VP28 were suggested as candidate vaccine components, but their uptake mechanism upon oral delivery was not elucidated. In this study the fate of these components and of live WSSV, orally intubated to black tiger shrimp (Penaeus monodon) was investigated by immunohistochemistry, employing antibodies specific for VP28 and haemocytes. The midgut has been identified as the most prominent site of WSSV uptake and processing. The truncated recombinant VP28 (rec-VP28), formalin-inactivated virus (IVP) and live WSSV follow an identical uptake route suggested as receptor-mediated endocytosis that starts with adherence of luminal antigens at the apical layers of gut epithelium. Processing of internalized antigens is performed in endo-lysosomal compartments leading to formation of supra-nuclear vacuoles. However, the majority of WSSV-antigens escape these compartments and are transported to the inter-cellular space via transcytosis. Accumulation of the transcytosed antigens in the connective tissue initiates aggregation and degranulation of haemocytes. Finally the antigens exiting the midgut seem to reach the haemolymph. The nearly identical uptake pattern of the different WSSV-antigens suggests that receptors on the apical membrane of shrimp enterocytes recognize rec-VP28 efficiently. Hence the truncated VP28 can be considered suitable for oral vaccination, when the digestion in the foregut can be bypassed.
