Abstract

Koi herpesvirus (KHV) which also known as Cyprinid herpesvirus 3 (CyHV-3), Koi herpes-like virus, and carp interstitial nephritis gill necrosis virus (CNGV), caused signifi cant morbidity and mortality in koi and common carp (Cyprinus carpio). The case fatality rate of this disease is 80–100%. Glycoprotein has been used for vaccine development as sub unit vaccine against viruses. The aim of this research was to clone and express membrane glycoprotein ORF124 KHV as a candidate of recombinant vaccine. ORF124 KHV gene was successfully cloned into pBSKS and sequenced. Result showed that ORF124 KHV (isolate from Indonesia) had 100 % similarity with Cyprinid herpesvirus 3 strain TUMST1 (from Japan), 99% similarity with Koi herpesvirus strain KHV-U (from USA) and Koi herpesvirus strain KHV-I (from Israel). Prediction analysis of T and B cell epitopes showed that ORF124 KHV protein had 14 and 11 T cell epitopes (IAd, Rothbard/Taylor pattern),and had 10 B cell epitopes, suggested that the protein can be used as a vaccine candidate. ORF124 gene has been expressed in Escherichia coli under pET32-a(+)vector.

Abstract

Iridovirus was known as agents that caused serious systemic disease in freshwater and marine fishes. The mortality up to 100% of orange-spotted grouper (Epinephelus coioides) due to iridovirus infection has been reported in Indonesia. The gene encoding capsid protein of iridovirus is supposed to be conserved and has the potency for the development of control methods. The objectives of this study are to clone the gene encoding capsid protein iridovirus and to analyze their sequences. The   spleen tissues of orange-spotted grouper were collected and extracted their DNA. The DNA fragment of capsid protein of iridovirus genes were amplified by PCR using designed primers with the extraction DNA as templates. The amplified DNA fragments were cloned in pBSKSII and sequenced.  The genes encoding capsid protein of iridovirus from Jepara and Bali were successfully amplified and cloned. The Jepara clone (IJP03) contained complete open reading frame (ORF) of the gene composed by 1362 bp nucleotides which encoded 453 amino acids. Those Jepara and Bali (IGD01) clones shared 99.8% similarity in nucleotide level and 99.4% at amino acid level. Based on those sequences, Indonesian iridovirus was belonged to genus Megalocystivirus and shared 99,6-99,9% similarity on nucleotide level with DGIV, ISKNV, MCIV, and ALIV

Abstract

The availability of specific and rapid detection methods is essential for monitoring the health status of farmed species, particularly in viral disease as in this case early diagnosis is a critical factor in containing disease outbreaks. Jembrana Disease Virus (JDV) is a lentivirus that causes an acute, severe disease syndrome in infected Bali cattle in Indonesia, resulting in heavy economic losses because of the high mortalities. The virus-host interaction and the modes of transmission are still unknown. The goal of the research was to designa probe candidate of Jembrana Disease Virus based on envelope-transmembrane (env-tm) gene to optimize Jembrana disease detection method. The DNA fragment derived from env-tm of JDV was used, cloned in pGEX-TM and expressed in E.coli DH 5α. Sequence analysis was conducted with BLAST programs from NCBI. Sequence analyses of the fragments of env-tm clone, indicated that it has a very closed genetic relation with 97,68% homology identity. Probe was designed based on the conserved region of env-tm using Geneious resulted in JT2 252 bp long. BLAST analyses showed that probes had high specifity to other strains of JDV in Indonesia.Key words : probe, env-tm, JDV, specifity, sensitivity.

Abstract

The effect of different initial time of artificial feeding to the growth and the activities of digestive enzymes of humpback grouper larvae Cromileptes altivelis (Valenciennes 1828).Humpback grouper is an economically marine finfish commodity, so it is important to scale up its culture. In aquaculture, feed is dominantly affecting to fish growth. Besides live feeds, theartificial feed is also given to fulfill the need of nutrient for larvae. However, the capability of larvae to digest the artificial feed is still limited because of its simplicity and immaturity of digestive system structure. Digestive enzymes are a biological indicator to figure out the capability of larvae to digest the artificial feed. This research was conducted to find out the influence of different initial time of artificial feeding to the growth and digestive enzyme activity of humpback grouper larvae. Larvae rearing were done in hatchery. Larvae were fed with live feed rotifers started in the evening of the second day. The treatment given in this research was the difference initial time of artificial feeding, i.e: (A) given at 8 days old larvae and (B) given at13 days old larvae. The variable observations were the growth and digestive enzyme activity of larvae. The results indicate that the different initial time of artificial feeding influenced to thegrowth and digestive enzyme activity of humpback grouper larvae. Total length, body weight, length of dorsal spine and ventral spine of 30 days old humpback grouper larvae on treatment A were 17.47±2.35 mm, 0.11±0.04 g, 6.83±0.45 mm and 5.07±0.50 mm, respectively, while on treatment B were 13.23±2.53 mm, 0.04±0.02 g, 5.73±1.11 mm and 4.48±0.50 mm, respectively. Up to 30 days old larvae, protease and amylase enzymes activities of larvae on treatment A was higher than on treatment B, while lipase enzymes activity of larvae on treatment B was higher than on treatment A. Therefore, the different initial time of artificial feeding gives the different effect on the growth and the activities of protease, amylase and lipase enzymes of humpback grouper larvae.Key words: artificial feed, growth, digestive enzyme activity, humpback grouper, larvae

Abstract

ABSTRAK Albinisme merupakan kelainan genetik autosomal resesif  berupa gangguan sintesis melanin yang terjadi pada manusia. Albinisme dibagi menjadi dua kelompok besar, yaitu Ocular Albinism (OA) dan Oculocutaneous Albinism (OCA). Berdasarkan gen yang mengalami mutasi, OCA dibedakan menjadi 4 tipe yaitu OCA1, OCA2, OCA3 dan OCA4. OCA4 disebabkan mutasi pada gen MATP. Penelitian yang telah dilakukan dengan PCR-SSCP (Polymerase Chain Reaction-Single Stranded Conformation Polymorphism) mendeteksi adanya mutasi pada ekson 5 gen MATP, pada penderita albinisme di Wonosobo, Jawa Tengah. Sekuensing ekson 5 gen MATP dilakukan untuk mengidentifikasi tipe mutasinya. DNA diisolasi dari sampel darah penderita dan digunakan sebagai template untuk amplifikasi ekson 5 gen MATP dengan metode PCR. Produk PCR selanjutnya digunakan sebagai template untuk sekuensing dengan metode Sanger. Hasil sekuensing dianalisis menggunakan program Clustal-W dan dibandingkan dengan sekuens ekson 5 gen MATP dari International DNA Data Base (nomer akses AF172849.1). Hasil analisis menunjukkan adanya pada perubahan basa nukleotida no.1122 dari C menjadi G (c.1122 C>G) yang mengakibatkan mutasi missense, yaitu fenilalanin menjadi leusin, pada asam amino nomer 374 (p.374 Phe/Leu).   Kata kunci : OCA4, mutasi, ekson 5, gen MATP
