“…Umumnya petambak memasok bibit dari balai benih yang letaknya jauh dari tambak sehingga perlu dilakukan proses pengangkutan. Tokolan udang yang diangkut selama berjam-jam dengan kepadatan populasi tokolan yang tinggi, supplai oksigen yang terbatas serta tanpa pertukaran media air akan menyebabkan udang mudah mengalami stres seperti yang dinyatakan oleh Anderson et al (1988) bahwa mortalitas akibat vibriosis terjadi ketika udang (pada semua fase kehidupan) dalam kondisi stres. Wickins dan Lee (2002) menyatakan bahwa penyakit kronis dapat mengakibatkan gangguan pertumbuhan dan menurunkan kualitas udang, sedangkan penyakit yang bersifat akut dapat menyebabkan kematian.…”

Abstract. The objective of present study was to evaluate the possibility of papaya’s latex (Carica papaya) as anti stress or larvaside for tiger shrimp (Panaeus monodon) post larvae Pl 14-30 during transportation. The tiger shrimp post larvae was collected from BBAP Ujung Batee, Aceh Besar on September, 2012. Reseach method used the completely random design with two factors, density of post larvae with three treatments (1000; 1500 dan 2000 ind/l) and concentration of papaya’s latex with four treatments (0; 100; 200 dan 300 ppm) and three replications for each treatments. The effect of papaya’s latex on tiger shrimp post larvae was observed by calculating the percentage of post larvae’s survival rate. The calculation was only done after twelve hours of transportation, due to the everage of survival rate percentage of post larvae on all levels of density was less than 50%. The ANOVA test showed that the density and the concentration factors gave significance effect on survival rate of tiger shrimp post larvae (P0,05). The results showed that survival rate of tiger shrimp post larvae (PL 14-30) were decreased with increasing of larvae density and concentration of papaya’s latex. However, Duncan’s test showed that the highest survival rate was obtained at 1.000 ind/l and 0 ppm of papaya’s latex. Hence, the effect of papaya’s latex concentration treatments in this study was larvaside on tiger shrimp post larvae.Key words: Closed transportation system, dissolved oxygen, enzyme papain, tiger shrimp post larvae.

“…The infected shrimp show the milky white signs on the body and appendages, weakness, disoriented swimming, lethargy, loss of appetite and show black spots of melanisation on the cephalothorax (Figure 2.6). Postlarvae may display cloudy hepatopancreas and brown gills (Anderson et al, 1988;Takahashi et al, 1985). Finally, it leads to death.…”

“…The cuticular colonisation is the cause of necrosis of the cuticular epithelium and the formation of melanised lesions. Septic hemocytic nodules are formed in the lymphoid organ, heart, connective tissues of the gills, hepatopancreas, antennal gland, nerve cord, telson and muscle (Anderson et al, 1988;Jiravanichpaisal et al, 1994;Mohney et al, 1991). In Thailand, vibriosis in P. monodon has the spheroids in the lymphoid organ (Nash et al, 1992).…”

STRUCTURES AND FUNCTIONS OF PENLECTINS AND THEIR INVOLVEMENT IN GASTROINTESTINAL IMMUNE SYSTEM OF BLACK TIGER SHRIMP Penaeus monodon

Tachylectin5A and Tachylectin5B, both contain a fibrinogen-related domain (FReD) and have been studied in japanese horseshoe crabs, Tachypleus tridentatus and shown to be involved in host defense. Here, we demonstrate the presence of tachylectin5- like genes in the shrimp, P. monodon, which we have named as Penlectin5-1 (PL5-1), Penlectin5-2 (PL5-2) and Penlectin5-3 (PL5-3). All three lectins contain a signal peptide and a single FReD with an acetyl group and a calcium binding sites. They are structurally similar to japanese horseshoe crab tachylectin5. The PL5-1, PL5-2 and PL5-3 transcripts were expressed in various shrimp tissues in normal shrimp, and its expression was up-regulated in tissues such as hemocytes, posterior intestine or stomach following challenge with pathogenic V. harveyi or V. parahaemolyticus (3HP). The PL5-1, PL5-2 and PL5-3 proteins were expressed in a bacterial expression system and they were expressed as non-soluble proteins. Only the PL5-2 protein was possible to isolate and purify from shrimp plasma using affinity chromatography, and therefore, the PL5-2 protein was used for functional studies of this protein. The PL5-2 protein was detected in various tissues as well as in cell-free hemolymph. The biological function of the PL5-2 protein is to recognize some Gram-positive and Gram-negative bacteria regardless whether they are non-pathogenic or pathogenic. This lectin had hemagglutination activity towards all types of human erythrocytes including A, B and O type, and it had also a bacterial agglutination activity to both Gram-negative and Gram-positive bacteria. Possible binding sites of PL5-2 to bacteria could be at the N-acetyl moiety of the GlcNAc-MurNAc cell wall of the peptidoglycan, since the binding could be inhibited by GlcNAc or GalNAC. To further understand the functions and the involvements of PL5-1, PL5-2 and PL5-3 in response to AHPND in shrimp, knockdown of the PL5 genes using RNAi was performed prior to an oral administration of Vibrio parahaemolyticus (VP3HP) causing AHPND. The results suggest that PL5-1, PL5-2 or PL5-3 silencing in shrimp challenged with VP3HP showed higher increases in mortality as well as more severity of histopathological changes. The presence of PL5-2 protein in both circulating hemolymph and gastrointestinal tract, where host and microbes are usually interacting, may suggest that the physiological function of shrimp tachylectin-like proteins is to recognize and bind to invading bacteria to immobilize and entrap these microbes and subsequently clear them from circulation and the host body. It is also probably possible that the Penlectins are involved in controlling and maintaining the normal flora in the intestine.
