Inhibitory Mechanism of Robiotic Bacteria on The Growth of Vibrio harveyi in Tiger Shrimp (Penaeus monodon) Larvae

Three probiotics named SKT-b, 1Ub, and Ua had inhibitory activity against the growth of Vibrio harveyi. These strains were mutated by rifampicin resistant. The inhibitory effect of SKT-b,1Ub, and Ua on the growth of V. harveyi was investigated by concomitant incubation of the two bacteria in a culture shrimp larvae. Colony forming unit of V. harveyi, probiotic and total of bacteria in dead, live larvae and water culture was monitored, and survival rate of larvae was investigated. Shrimp inoculated probiotic previously had survival rate higher than control (without probiotic). Number of V. harveyi in treatment without probiotic inoculation also higher compared to treatment with probiotic inoculation in dead, live larvae and water culture. It demonstrated possible inhibition of probiotic bacteria on V. harveyi through competition for adherence sites or nutrition source. Partial sequencing of 16S-rRNA gene showed that 1Ub was similar to Pseudoalteromonas piscicida, whereas SKT-b and Ua were similar to Vibrio alginolyticus. Keywords: probiotic bacteria, inhibitory mechanism, V. harveyi, tiger shrimp ABSTRAK Tiga isolat bakteri probiotik yaitu 1Ub, SKT-b dan Ua telah diuji memiliki aktivitas penghambatan terhadap pertumbuhan V. harveyi secara in vitro. Ketiga isolat ini kemudian diberi penanda resisten rifampisin (RfR) melalui mutasi spontan untuk mempelajari mekanisme penghambatannya pada larva udang windu. Efek penghambatan dari 1Ub, SKT-b dan Ua terhadap pertumbuhan V. harveyi diamati melalui pemberian secara bersamaan antara bakteri probiotik dan V. harveyi tersebut dalam air pemeliharaan larva udang. Jumlah sel bakteri probiotik, V. harveyi dan total bakteri baik pada larva mati, larva hidup dan air pemeliharaan diamati dan kelangsungan hidup larva dihitung. Nilai kelangsungan hidup udang pada perlakuan yang diinokulasi bakteri probiotik lebih tinggi daripada kontrol (tanpa penambahan bakteri probiotik). Jumlah sel V. harveyi pada perlakuan tanpa penambahan probiotik juga lebih tinggi, dibanding pada perlakuan dengan penambahan probiotik baik pada larva mati, larva hidup maupun air media pemeliharaan. Hal ini menunjukkan adanya penghambatan bakteri probiotik terhadap V. harveyi yang kemungkinan melalui kompetisi tempat pelekatan atau sumber nutrisi. Hasil analisis sekuen sebagian gen 16-rRNA menunjukkan bahwa isolat 1Ub termasuk spesies Pseudoalteromonas piscicida, sedangkan SKT-b dan Ua termasuk spesies Vibrio alginolyticus.

Penelitian ini bertujuan untuk memperoleh bakteri probiotik yang mampu menghambat pertumbuhan Vibrio harveyi mengggunakan metode kultur bersama. Sebanyak 51 isolat kandidat probiotik berhasil diisolasi dari larva udang dan lingkungan pemeliharaannya di Balai Pengembangan Benih Ikan Air Payau dan Udang (BPBILAPU), Pangandaran serta hatcheri udang PT Biru Laut Khatulistiwa dan tambak udang intensif di Lampung. Dari total isolat tersebut setelah diseleksi secara in vitro menggunakan metode kultur bersama dipilih 3 isolat kandidat probiotik yang paling potensial dalam menekan atau menghambat pertumbuhan V. harveyi MR 5399 RfR yakni 1Ub, P20Bf, dan 10a. Ketiga isolat tersebut selanjutnya digunakan pada uji patogenisitas dan uji tantang pada larva udang windu. Hasil uji patogenisitas dengan konsentrasi bakteri 106 CFU/mL menunjukkan bahwa ketiga isolat tersebut tidak bersifat patogen pada larva udang windu. Hasil uji tantang pada larva udang juga menunjukkan bahwa ketiga isolat tersebut mampu meningkatkan sintasan larva udang windu. Nilai sintasan larva pada perlakuan yang selain diinfeksi dengan V. harveyi MR5399 RfR juga ditambah probiotik 1Ub, P20Bf, dan 10a masing-masing adalah 90,0%; 86,7%; dan 78,3% sedangkan pada perlakuan yang hanya diinfeksi dengan V. harveyi MR5399 RfR tanpa probiotik nilai sintasannya hanya mencapai 73,3%. Populasi bakteri V. harveyi pada perlakuan dengan penambahan bakteri probiotik lebih rendah dibanding perlakuan tanpa probiotik, hal ini menunjukkan kemungkinan adanya kompetisi antara bakteri V. harveyi dengan 1Ub.This research was aimed to obtain probiotic bacteria that can be used to inhibit the growth of Vibrio harveyi using co-culture method. This method succeeded in isolating 51 probiotic bacteria candidates from shrimp larva and their rearing environment in Balai Pengembangan Benih Ikan Laut Payau dan Udang (BPBILAPU), Pangandaran and shrimp hatchery of PT Biru Laut Khatulistiwa and intensively managed shrimp pond in Lampung. After in vitro selection of the total isolates using co-culture method, three most potential probiotic bacteria candidates in inhibiting or suppressing growth of V. harveyi MR 5399 RfR bacteria were chosen. The three isolates were then used in pathogenicity and challenge test in tiger shrimp larva. Results of pathogenicity test at the concentration of 106 CFU/mL bacteria showed that the three isolates were not pathogen to tiger shrimp larvae. Challenge test results in shrimp larvae also showed that the three isolates could increase survival rates of tiger shrimp larva. Larva survival rate value of treatment using V. harveyi MR5399 RfR with 1Ub, P20Bf, dan 10a probiotic were 90.0%, 86.7% dan 78.3%, respectively; whereas infection treatment merely using V. harveyi MR5399 RfR without probiotic only gave 73.3% survival rate. V. harveyi population in treatment with addition of probiotic bacteria were lower than that of without probiotic. This suggested the existence of possible competition between V. harveyi and 1Ub bacteria.

Aim: The present study investigated hemocytes profile of black tiger shrimp (Penaeus monodon) induced with Xylocarpus granatum leaves extract to protect against Vibrio harveyi infection. Materials and Methods: X. granatum leaves were chopped into small size, air-dried, and extracted with one of the following solvents: Ethanol, distilled water, and seawater, whereas each solvent was given in three different concentrations (750 ppm, 1.000 ppm, and 1.250 ppm, respectively). Extracts were induced to 60 post-larvae shrimp in each treatment (three replicates, 20 shrimp for each) by immersing method and subsequently challenged with V. harveyi. Results: This study demonstrated different effectiveness among solvents used to extract X. granatum leaves, in which distilled water showed the most effective solvent as can be seen from the lowest percentage on anorexia, lethargic, and weakened reflex of shrimp compared with another solvent, positive and negative controls. Pathological symptoms for shrimp induced by X. granatum leaves extract were minimum with the highest survival rate compared with those of positive and negative control. Total hemocyte cells and its cell constituents such as semi-granular, granular, and hyaline cells on treatment group at 1.250 ppm were higher than controls. Conclusion: Leaves extract of X. granatum extract effectively inhibited V. harveyi infection, increased survival rate, and hemocytes cell of the experimental shrimp. Distilled water extract of X. granatum at 1.250 ppm demonstrated the highest protective effect toward V. harveyi infection on P. monodon.

Teknologi RNA interference (RNAi) merupakan salah satu pendekatan yang digunakan untuk meningkatkan resistensi udang windu terhadap infeksi patogen termasuk WSSV. Pengembangan teknologi RNAi melalui aplikasi untai ganda RNA (dsRNA) yang berasal dari gen pengkode viral protein (VP) dari WSSV telah mulai dikembangkan pada udang. Penelitian ini bertujuan untuk mengkaji sintasan dan respons imun udang windu yang diberi VP-15 pasca uji tantang dengan WSSV. Udang windu (panjang 15,21 ± 1,19 cm dan bobot 32,5 ± 1,83 g) diinjeksi dengan 0,2 µg/ekor dsRNA in vitro (A), dsRNA in vivo (B), dan larutan garam/kontrol (C). Setelah tiga hari vaksinasi, udang windu ditantang dengan WSSV dengan dosis 50 µL/ekor. Pengamatan sintasan dilakukan setiap hari, sedangkan respons imun (THC dan aktivitas proPO) dilakukan pada awal dan hari ke-1, ke-3, dan ke-5 pasca uji tantang, serta analisis ekspresi gen antivirus dan histopatologi hepatopankreas dilakukan pada akhir penelitian. Hasil penelitian menunjukkan bahwa aplikasi dsRNA berpengaruh nyata (P<0,05) terhadap sintasan, THC, dan proPO. Sintasan udang windu yang diberi dsRNA VP-15 in vitro dan in vivo memberikan sintasan yang lebih tinggi 75% dibandingkan dengan kontrol. Nilai proPO tertinggi didapatkan pada dsRNA in vivo (0,138); kemudian dsRNA in vitro (0,093); dan terendah kontrol (0,061); sedangkan THC tertinggi (5.704 x 104 sel/mL) pada dsRNA in vivo, kemudian dsRNA in vitro (3.516 x 104 sel/mL) dan terendah pada perlakuan kontrol (3.322 x 104 sel/mL). Ekspresi gen antivirus semakin meningkat dengan semakin lamanya udang windu terpapar dengan WSSV. Jaringan hepatopankreas udang windu pada perlakuan kontrol (tanpa dsRNA) menunjukkan adanya kerusakan sel akibat infeksi virus.RNA interference (RNAi) technology is one of the approaches used to improve tiger shrimp Penaeus monodon resistance against WSSV infection. The development of RNAi technology through double-stranded RNA (dsRNA) isolated from gene encoding viral protein (VP) of WSSV has been applied to shrimp. This study was aimed to assess the survival rate and immune response of injected-VP-15 WSSV tiger shrimp after a challenge with WSSV. The tiger shrimp (15.21 ± 1.19 cm in length and 32.5 ± 1.83 g in weight) were injected with 0.02 µg/shrimp of in vitro dsRNA (A), in vivo dsRNA (b) and saline solution (C). After three days of vaccination, the tiger shrimp were challenged with WSSV using a dosage of 50 µL/shrimp. The survival rate was observed daily. Analyses of immune responses (hemocyte total and PO activity) were performed in several stages: before the challenge test and day-1, day-3, and day-5 post-challenge test. The expression of the antivirus gene and hepatopancreas histophatology were was observed at the end of the experiment. The results showed that the application of dsRNA significantly influenced the shrimp survival rate, THC, and proPO. Tiger shrimp injected with dsRNA VP-15 of in vitro and in vivo exhibited a higher 75% survival rate than the control (P<0.05). The highest proPO activity (0.138) was obtained at dsRNA in vivo, followed by dsRNA in vitro (0.093) and the lowest (0.061) in the control. The highest THC (5,704 x 104 cell/mL) was in vivo dsRNA, then in vitro dsRNA (3,516 x 104 cell/mL), and the lowest in the control (3,322 x 104 cell/mL). The longer the exposure with WSSV, the higher the antivirus gene expression. Histopathology analysis showed some damages to the hepatopancreas cells in the control shrimp (without dsRNA) caused by the virus infection.

ABSTRACT Application of probiotic bacteria is an alternative technology to increase shrimp production in an environmentally friendly aquaculture. Administration of probiotic bacteria can be conducted through artificial feed or live food such as Artemia. This study was done to examine the effectiveness of various doses of probiotic Vibrio SKT-b through Artemia on the growth and survival of post-larval shrimp. Tiger shrimp at a stage of PL 10 was reared in glass jars filled with 2 L of sea water at a density of 10 larva/L. The study consisted of five probiotic concentrations control (0 cfu/mL), A (103 cfu/mL), B (104 cfu/mL), C (105 cfu/mL), and D (106 cfu/mL). Administration of various doses of probiotic bacteria Vibrio SKT-b through Artemia significantly increased the growth rate in term of the length and weight, but had no effect on survival. The results found that treatment D (106 cfu/mL) gave an increase in body weight, length and survival rate of 22.53%/day, 0.080 cm/day and 95%, respectively. Keywords: probiotic, Artemia, tiger shrimp ABSTRAK Aplikasi bakteri probiotik merupakan salah satu alternatif teknologi untuk meningkatkan produksi budidaya udang yang ramah lingkungan.

A 45-days feeding trial was conducted on juvenile tiger shrimps Penaeus monodon of size 0.997±0.098 g with diets containing Mannan oligosaccharides (Mos) at three graded levels (0.1, 0.2 and 0.3%). Maximum weight gain (1.353 g) was achieved in shrimps fed with 0.3% Mos concentration, followed by 0.2% Mos (1.224 g). Best feed conversion ratio (FCR) of 2.406 was registered in 0.3% Mos groups. Results indicate that there was a significant difference (p<0.01) in weight gain and FCR among the treatments. However, no statistical differences were observed on the specific growth rate (SGR), mean feed intake and survival rate. Feeding trial was followed by a 10 days challenge study with Vibrio harveyi by intramuscular injection and white spot syndrome virus (WSSV) by feeding WSSV infected tissues. Significantly higher survival rate was observed in the shrimp groups fed with 0.3% Mos (66.67%) than the other treatments when challenged with V. harveyi. Tiger shrimps fed with 0.3% Mos challenged with WSSV showed a significantly higher survival rate (66.67%), followed by 0.2% Mos (50%), 0.1% Mos (25%) and control (25%) on day 5 post-challenge. However On day 10 post-challenge with WSSV, except in the groups fed with 0.3% Mos (16.67% survival), 100% mortality was noticed in all other diet groups. Therefore, it is concluded that dietary administration of Mos at 0.3% would enhance the growth and survival of tiger shrimp against V. harveyi. With respect to WSSV challenge, it appears that, though Mos at 0.3% had a positive effect on the shrimp, higher survival was not observed. Whether additional increment in Mos supplementation in the diet would positively affect the survival of tiger shrimps post-WSSV challenge, needs to be investigated further.
