Abstract

Tarsius is an endemic species in Indonesia but is is getting threatened. In-situ and ex-situ conservationof this species would yield better results when its genetic information and diversity determined. Theobjective of this ressearch was to study the genetic diversity of ND3 gene of Tarsius sp. Based on sequencingof PCR products using primer ND3F and ND3R resulted in 437 nts base sequence. Results of ND3 fragmentssequencing were put on multiple alignment with other primates from Genbank using of software ClustalW, and then were analyzed using MEGA program version 4.1. A different nucleotide site was found(nucleotide no. 24). The genetic distance based on nucleotide ND3 was calculated using Kimura 2-parametermodel. The genetic distance showed the smallest genetic distance 0%, the biggest 0,03% and average0,01%. The phylogenetic tree using neighbor joining method based on the sequence of nucleotide ND3 genecould not be used to differentiate among T. Dianae (from Central Sulawesi), T. Spectrum (from NorthSulawesi) and T. bancanus (from Lampung, South Sumatera).

Abstract

Tengger’s horse (Equus caballus) is a local Indonesian horse an originated from its ancestor in Java.As the population of Tengger’s horse is almost extinct it is important to conserve and increase the horsepopulation by in situ or ex situ conservation.The objective of this research was to study the moleculargenetic of partial D-loop of Tengger’s horse. Sequencing of PCR product, showed that the D-loop consistedof 319 nucleotides. The DNA was isolated from whole blood and amplified and sequenced using a publishedprimer sets. The sequence was aligned and compared with horse D-loop sequences available in Genebankusing Clustal W method in MEGA program version 4.0.2. Ten different nucleotide sites were found inTengger horse from (nucleotide no. 9, 52, 64, 69, 102, 117, 133, 170, 187 and 293). The genetic distanceanalised using Kimura 2-parameter model ranged between 0,0% and 3,2%, with the average of 1,7%. Thephylogenetic tree using neighbor joining method based on the sequence of nucleotide partial D-loop couldnot be used to differentiate among horse from Tengger and E. caballus.

Abstract

In a conservation effort, the identification of Tarsier species, on the bases of the morphological andmolecular characteristic is necessary. Up to now, the identification of the animals were based on themorphology and vocalizations, which is extremely difficult to identify each, tarsier species. The objective ofthis research was to study the genetic diversity on ATP6 gene of Tarsius sp. Based on sequencing of PCRproduct using primer ATP6F and ATP6R with 681 nts. PCR product. The sequence of ATP6 fragmentswere aligned with other primates from Gene bank with aid of software Clustal W, and were analyzed usingMEGA program version 4.0. Three different nucleotide sites were found (nucleotide no. 288, 321 and 367).The genetic distance based on nucleotide ATP6 sequence calculated using Kimura 2-parameter modelindicated that the smallest genetic distance 0%, biggest 0.8% and average 0, 2%. The phylogenetic treeusing neighbor joining method based on the sequence of nucleotide ATP6 gene could not be used todifferentiate among T. Dianae (from Central Sulawesi), T. Spectrum (from North Sulawesi), T. bancanus(from lampung, South Sumatera) and T.bancanus from West Kalimantan.

Abstract

The aim of study was to identify  Myxobolus sp. obtained from the gills of carp (Cyprinus carpio) ofEast Java, Indonesia. The cysts containing spores were collected from the gills of carp fish. The spores wereexamined by wet mounts preparation, fixed with ethanol absolute solution for molecular analysis. Thespores had a transparent membrane, the shell, composed of two valves. The sutural ridge running betweenthe valves. It was two anterior polar capsules, each consisted of a coiled polar filament. An iodinophilicvacuole and sporoplasm nuclei was located in posterior part. DNA Sequenses 18S rDNA followed byphylogenetic tree demonstrated that Myxobolus sp from Blitar was different from Myxosoma cerebralis ofthe Gene Bank. Myxosoma cerebralis was not found  in the fresh water fish in Indonesia.

Abstract

In conservation, identification of tarsier species based on morphological and molecular characters isrequired. However, to date the identification of animals is simply based on their morphological characterand vocalizations, while in fact it is difficult to identify each species of Tarsius sp morphologicaly.  Thepurpose of this study is to obtain genetic markers that can be used to identify Tarsius sp on ND6 mitochondrialgenes and reveal affiliations and phylogenetic relationships Tarsius sp. with other members of primates.Samples were obtained from several original habitats of Tarsius sp. Three samples were taken from NorthSulawesi, one sample was collected from Central Sulawesi, three samples from Kalimantan  and threesamples from South Sumatra. The isolated DNA is then used as a template for amplification of DNAfragments by PCR. Amplicon (PCR product) obtained 566 bp and 629 bp. Nucleotide sequencing resultsshows 513 nucleotides, the smallest genetic distances of 0%, the highest of 30.2% and average of 16.3%.Nucleotide and amino acid sequences of ND6 can be used as genetic markers to differenciate T. spectrum,T. dianae and  T. bancanus but they fail to function as genetic markers to distinguish  T. bancanus ofKalimantan and Sumatra origin.

Abstract

Tarsius merupakan salah satu satwa endemik Indonesia yang keberadaannya mulai memprihatinkan. Konservasi sebagai salah satu cara untuk pelestarian satwa ini akan lebih terarah dan berhasil guna apabila karakteristik dan keragaman sumber genetiknya diketahui dengan pasti. Tujuan dari penelitian ini adalah mengkaji penanda genetik spesifik gen cyt b pada Tarsius sp. Pengurutan hasil PCR menggunakan primer H 15149 pada gen cyt b didapatkan urutan basa sebesar 276 pb (menyandi 92 asam amino. Fragmen cyt b hash! pengurutan disejajarkan berganda dengan primata lain dari data Genbank dengan bantuan perangkat lunak Genetyx-Win versi 3.0 dan Clustal W, kemudian dianalisis dengan menggunakan program MEGA versi 3.1. Dari hasil analisis diperoleh 14 situs asam amino yang berbeda. Tarsius dianae memiliki 12 situs asam amino (asam amino ke 2, 6, 9, 22, 23, 29, 39, 41, 42, 45, 55 dan 85), T. spectrum memiliki 7 situs asam amino (asam amino ke 2, 6, 9, 41, 45, 55 dan 85) dan T bancanus memiliki 2 situs asam amino ( ke 23 dan 45) yang dapat digunakan sebagai penanda genetik. Lima asam amino unik ditemukan pada T dianae, yaitu pada situs asam amino ke 6 (valina), ke 22 (alanina), ke 29 (alanina), ke 39 (serina) dan ke 42 (valina). Jarak genetik berdasar nukleotida cyt b yang dihitung menggunakan model 2 parameter Kimura ditemukan nilai paling kecil sebesar 0,7%, nilai paling besar 22,3% dan rata-rata 13,1%. Filogram menggunakan metode neighbor joining berdasar hasil urutan nukleotida dan asam amino cyt b tersebut dapat dijadikan pembeda masing-masing spesies Tarsius.

Abstract

Abstract Staphylococcus aureus is the main bacterium found in cows and goats milk. The bacteria can produce toxin called toxic shock syndrome toxin-1 (TSST-1) that can infect humans and animals causing several serious diseases. The objective of this study was to detect the existence of encoding gene of TSST-1 S. aureus isolate from cows and goats milk. The research is initiated by re-identification stage of S. aureus conventionally continued by identification based on the molecular method of polymerase chain reaction (PCR). A number of 10 S. aureus isolates from cows and goats milk cultured in aerobics continued by Gram stain, catalase, coagulase, MSA, VJA and VP tests. The identification of S. aureus based on the molecular approach conducted by 16S rRNA gene amplification continued with amplification of TSST-1 encoding gene as the target gene. The PCR product of TSST-1 encoding gene then sequenced to ensure whether the DNA fragment amplified is the TSST-1 encoding gene or not. The result of the research indicates that re-identification of S. aureus conventionally generating positive reaction of S. aureus species. Molecular identification of 16S rRNA gene amplification gives a good result by producing DNA fragment of 745 bp size and meets the target gene. The detection result of encoding gene TSST-1 gives negative result marked by DNA fragment which the size does not match the target gene. The allignment result of sequence isolate SA.1 indicates that the sequence is not tst gene but the gene which coded glutamate sinthetase belongs to S. aureus, whereas sequence of isolate KI.8 is 50S rRNA gene belongs toS. saprophyticus.
