Vibrio parahaemolyticus is one of the pathogenic bacteria that cause vibriosis. V. strain expresses PirA and PirB toxins main causative agent Acute Hepatopancreatic Necrosis Disease which causes necrosis (cell death) suddenly in hepatopancreatic organs shrimp. The environmentally friendly approach to prevent bacterial infections shrimp through application probiotics. Probiotic isolates originated from same environment as host pathogen were expected have a better adaptation competition...

The production of shrimp has been challenged by various factors such as diseases. Therefore, the health cultured is essential for successful farming practices. application medicinal plants brings about numerous benefits in aquaculture including simplicity usage, biodegradability, and minimal environmental impact over extended periods. This study was conducted to evaluate efficacy E. longifolia, C. zedoaria, A. sativum improve immune response resistance vannamei an effort prevent Vibrio...

Graphical Abstract Highlight Research vB_Vp_TSK01 and vB_Vp_JKT02 a specific parahaemolyticus bacteriophage were isolated from the shrimp aquaculture water. Compared to control reduced 11.46±1.35% of bacterial growth, by 9.86±5.92% for treatment. Their cocktail had highest parahemolyticus growth inhibition 30.92±3.89%. The phage treatment increased survival Artemia 28.57% compared infection control. Acute Hepatopancreatic Necrosis Disease (AHPND) caused V. was one major diseases in culture...

The smart city concept is closely related to efficient traffic management, especially using technology improve safety and smooth flow, including at lights. In this context, light integration into a system uses sensors, surveillance cameras, intelligent algorithms adaptively manage based on vehicle volume real-time conditions. CCTV already installed in several junction road Bandung City, Indonesia. Image classification deep learning an essential rapidly growing application artificial...

Abstract This study aimed to evaluate and unveil the positive impact of biofloc culture on Vibrio parahaemolyticus infection Pacific white shrimp by reducing quorum sensing (QS) virulence gene expression enhancing shrimp's immunity. The with an average body weight 0.50 ± 0.09 g were reared in containers a volume 2.5 L, 21 units, density 20 L −1 . cultured for 5 days, each treatment including system maintenance C/N ratio 10 control without biofloc, followed challenge test through immersion...

This study aimed to characterize Bacillus sp.NP5 and evaluate the effectiveness of its application as a probiotic on growth performances health status common carp (Cyprinus carpio) before after infected by Aeromonas hydrophila.Bacillus cells were given carps through feed for 30 days at doses 10 6 , 8 CFU gG 1 feed.On day 31, challenged with A. hydrophila, which was injected via intramuscular route.Result phenotypic genotypic identification isolate showed that this cereus 99% similarity...

Streptococcus agalactiae and Aeromonas hydrophila have been recognized as the causative agents of mortality in tilapia larvae with single infection coinfection. The objective this study was to evaluate efficacy maternal transfer offspring protection from immunization monovalent bivalent vaccines on Nile (Oreochromis niloticus) broodstock larval immunization. Four groups were intraperitoneally injected formalin killed whole-cells S. (Sa group), A. (Ah mixed vaccine them (Biv...

ABSTRACTThis study aimed to produce microencapsulated probiotic Pseudoalteromonas piscicida (1Ub) and evaluate it with preb­iotic mannan-oligosaccharide (MOS) through the enrichment of Artemia sp., on bacterial population, growth performances, immune responses, disease resistance Pacific white shrimp larvae. Microencapsulation was done by freeze-drying method. The larvae were reared for 13 days fed sp. enriched microcapsule 1Ub (10 g/L), prebiotic MOS (12 mg/L), synbiotic, control without...

Application of bioflocs technology and probiotics has improved water quality production Pacific white shrimp (Litopenaeus vannamei) culture. This experiment was to verify the effect probiotic bacteria addition different carbon:nitrogen (C:N) ratio on performance nursery Nursery culture carried out for 25 days in an aquarium under laboratory condition with stock density one Post-Larvae (PL) (poslarval) per liter (24 PL/aquarium) PL16 shrimp. Different C:N resulted a significant difference...

This study aimed to examine the use of Streptococcus agalactiae polyvalent vaccine in tilapia broodstock and effect maternal immunity resistance on their offspring against S. strain. The was injected with at a dose 108 CFU per fish 2nd gonadal maturity until spawning. Challenge test carried out 5, 10, 15 20 days after hatching using NK1, N17O, N14G, N3M, N4M strain respectively combination them. We observed immunological parameters broodstock, eggs larvae relative cent survival (RPS)...

This study was carried out to obtain Vibrio isolates able function as biocontrol of vibriosis in shrimp hatchery. Thirty one were isolated from tiger larvae and hatchery environments, i.e. Labuan, Pangandaran, Lampung, Indonesia. Pathogenic V. harveyi MR5339 obtained Maros, South-Sulawesi made a rifampicin resistant mutant (RFR) screen for those 31 vitro assays allow us monitor their presence larval rearing water. Almost all Vibrio could inhibit the growth pathogenic RFR. SKT-b isolate...


 ABSTRACT
 White spot disease caused by Spot Syndrome Virus (WSSV) is the most serious viral and has a major impact on decline in production of white shrimp farm. Improving immune response through application prebiotic, probiotic synbiotic expected to be one environmentally friendly alternatives prevent disease. This study aimed evaluate effect administrating Baccillus sp. NP5 probiotic, honey prebiotic combination both (synbiotic) enhancing resistence WSSV infection. consisted...

Deoxyribonucleic acid (DNA) vaccine has recently been developed as an alternative against virus infection.This study was the first step of DNA development to protect cyprinids including common carp (Cyprinuscarpio) and fancy koi (Cyprinus carpio) from KHV (koi herpesvirus) infection in Indonesia. One glycoproteingenes, i.e. glycoprotein (GP) ligated with Japanese medaka (Oryzias latipes) â-actin promoter generatepAct/GP a vaccine. Fourty fish body weight 10-15 g/fish were individually...

Background . Ice-ice disease is still a big challenge for seaweed farming that characterized with “bleaching” symptom. Bacteria are suspected as cause of ice-ice on Kappaphycus alvarezii. The 16S rRNA gene sequencing current technique used bacterial phylogeny and taxonomy studies. This study was aimed to identify onset K. Methods Eight sequenced isolates from Indonesia were identified by biochemical tests target. sequence compared the strains bacteria GenBank. DNA sequences analyzed ClustalW...
