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

Reticulated python (M. reticulatus) Java and Kalimantan locality highly demand as pet animal. Blood profile has an important role on animal health status. This research was aim to study the blood profile comparison of Java and Kalimantan M. reticulatus. Ten blood samples of Java M. reticulatus and 10 samples of Kalimantan M. reticulatus were used in this study. As much as 1 ml blood sample was collected from ventral coccygeal vein of adult healthy M. reticulatus. Blood sample put into tube with EDTA then analized at Internal Department Laboratory, Faculty of Veterinary Medicine UGM. Based on blood samples analize results, adult healthy Java M. reticulatus shows the higher value on parameters of erytrocyte, leucocyte, PCV, MCH, heterophyl, limphocyte and monocyte, while haemoglobin, TPP, MCV, MCHC, azurofil and monosit were lower than Kalimantan M. reticulatus. There were no significant differences (P>0,05) between blood profile of Java and Kalimantan M. reticulatus. It could be concluded that blood profile of Java and Kalimantan M. reticulatus is not different.

Samples of blood were collected from five male bottlenose dolphins from PT. Wersut Seguni Indonesiacaptivity. Total deoxyribonucleic acid (DNA) was isolated from blood samples, then amplified by polymerase chain reaction (PCR), sequenced,and the data were analyzed using MEGA version 5.1 program. The amplification result of the PCR product obtained 824 base pairs (bp), andDNA sequencing obtained 684 nucleotides constituent of COX II genes that encode 228 amino acids making up the COX II. Nucleotide andamino acid sequence of COX II bottlenose dolphins originated from Java sea has a very high homology to Tursiops aduncus that are 99.13%and 100% respectively. Phylogram by neighbour joining method based on the nucleotide sequence of COX II gene indicating bottlenose dolphinsfrom Java sea belongs to group of Tursiops aduncus.Key words: bottlenose dolphin, COX II gene, nucleotide, Jawa Sea

Abstract

Rhiphicephalus (Boophilus) microplus is important obligatory blood feeding ectoparasites transmittingmany different viral, bacterial and protozoan and plays a role as a vector of Babesia sp., The leria sp. andAnaplasma sp. in cattle. The accuracy in identifying and distinguishing interspecies and intraspeciesdiversity among parasites is needed to understand the epidemiology, biology and capacity as a vector.Variations in the DNA base sequence of the internal transcribed spacer region2 (ITS 2) has been used asa molecular marker for identification in an effort to determine phylogenetic relationships. The aim of thisstudy was to determine the ITS 2 gene nucleotide sequence of R. microplus, which was expected to beuseful for accurate identification the parasite diversity and phylogenetic relationship among many differentspecies. DNA amplification was conducted using BOO2 forward dan BOO2 reverse primers. The DNAsamples containing ITS2 region fragment of 1099 nt were derived from the nucleotide sequence multiplealignments of R.microplus and other ticks genes obtained from Gene bank using Clustal W software, andthen analyzed using the MEGA program version 6. Genetic distances based on nucleotide sequence weredetermined with Kimura 2-parameter method producing the smallest genetic distance of 0 % and 1.2 %.Construction of phylogenetic trees using the Neighbor joining method showed that ticks from variousregions in Indonesia was species complex which have a closer with R.microplus isolates from India, Laos,South Africa, China and Australia R.australis origin.

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

Penelitian ini bertujuan mengkaji keragaman genetik gen penyandi ND4 pada Tarsius bancanus, T. b. borneanus, T. dianae dan T. spectrum dan untuk penegakan taksonominya. Deoxyribonucleic acid (DNA) diisolasi dari biopsi jaringan masing-masing spesies Tarsius dengan cara diekstraksi untuk digunakan sebagai DNA cetakan dalam proses amplifikasi dengan metode polymerase chain reaction (PCR). Primer yang digunakan dalam penelitian ini didesain untuk mengamplifikasi gen ND4 dan dilanjutkan dengan elektroforesis. Produk PCR hasil amplifikasi yang telah dimurnikan, selanjutnya dipergunakan sebagai DNA cetakan untuk reaksi penentuan runutan nukleotida. Runutan nukleotida gen ND4 hasil pengurutan dilakukan penjajaran berganda dengan primata lain yang diambil dari Genbank menggunakan Clustal W. Selain berdasarkan runutan nukleotida, gen ND4 dianalisis berdasarkan runutan asam amino dari basa-basa yang diterjemahkan mengikuti vertebrate mitochondrial translation code yang ada pada program MEGA versi 4.1. Konstruksi pohon filogenetika menggunakan metode neighbor joining. Hasil penelitian menunjukkan dari 1378 nukleotida ditemukan 119 situs yang bersifat beragam. Jarak genetika berdasarkan nukleotida gen ND4 yang dihitung menggunakan model dua parameter Kimura, terdapat nilai paling kecil 0,6%, nilai terbesar 13%, dan nilai rata-rata sebesar 6,1%. Filogram berdasarkan hasil runutan nukleotida gen ND4 yang menggunakan metode neighbor joining, dapat mengidentifikasi dan membedakan percabangan antar spesies Tarsius.

Abstract

Tujuan dari penelitian ini adalah mengaji keragaman genetik gen ND4L masing-masing spesies Tarsius yang dapat digunakan sebagai penanda genetik. Hasil polymerase chain reaction (PCR) gen ND4L menggunakan primer ND4LF dan ND4LR diperoleh 478 bp, setelah dilakukan sekuensing didapatkan sekuen gen ND4L sebesar 297 nt. Sekuen gen ND4L disejajarkan berganda dengan primata lain dari Genbank menggunakan Clustal W, dan kemudian keragaman genetik antar spesies dianalisis menggunakan program MEGA versi 5.0 (Nei dan Kumar, 2002). Di antara sampel Tarsius ditemukan satu situs nukleotida beragam, yaitu pada situs ke 162. Jarak genetik berdasarkan basa nukleotida ND4L dihitung menggunakan model dua parameter-Kimura menunjukkan paling kecil sebesar 0%, paling besar 0,3%, dan rata-rata 0,1 %. Pohon filogenetik menggunakan metode Neighbor joining tidak dapat membedakan antara Tarsius dari Sumatera, Kalimantan, dan Sulawesi, dan mengelompokkan Tarsius dalam subordo Strepshirrini.
