Enzim lipase EC 3.1.1.3, triasilgliserol asilhidrolase merupakan kelompok enzim yang menghidrolisis lemak menjadi asam lemak dan gliserol. Selain itu, enzim lipase berperan dalam berbagai rekasi, seperti reaksi esterifikasi, interesterifikasi, dan transesterifikasi. Penelitian ini bertujuan melakukan subkloning gen lipase Bacilus subtilis dari vektor pGEMlipA ke dalam vektor pSKE xyn AQ1 dengan metode Exponential Megapriming PCR EMP dan transformasi vektor pSKExynlipA rekombinan ke Bacilus subtilis DB104. Megaprimer yang digunakan untuk EMP disintesa melalui reaksi PCR menggungakan primer spesifik gen lipase yang didesain berdasarkan deret nukleotida gen lipA dan xynAQ1 sedemikian rupa sehingga merupakan gabungan deret nukleotida kedua gen tersebut, dengan vektor pGEMlipA sebagai template DNA. Produk PCR yang dihasilkan berukuran 792 pb selanjutnya digunakan sebagai megaprimer untuk EMP dengan vektor pSKExynAq1 sebagai template DNA. Produk EMP yang dihasilkan pSKExynlipA kemudian ditransformasikan ke dalam E. coli DH5 ? ? . Tahap selanjutnya vektor diekstraksi dari E. coli untuk ditransformasikan ke dalam B. subtilis DB104 dengan metode protoplasting dilanjutkan dengan tahap integrasi gen lipA ke dalam kromosom B. subtilis DB104. Kloning gen lipase ke dalam vektor pSKExynAq1 dengan metode EMP telah berhasil dengan diperolehnya pita berukuran sesuai harapan, yaitu 7849 pb. Produk EMP tersebut berhasil mentransformasi E. coli DH5 ? ? yang tumbuh pada media LB yang mengandung ampisilin. Seleksi kualitatif klona positiF menggunakan media agar mengandung asam tri butirat TBA, tri-butyric acid berhasil mendapatkan 1 klona klon 1 yang menghasilkan zona bening. Plasmid rekombinan yang diisolasi dari klon 1 tersebut berhasil ditransformasikan ke dalam B. subtilis DB104 pada media DM3 mengandung eritromisin. Analisis menggunakan enzim restriksi PstI terhadap plasmid pSKExynlipA yang diekstraksi dari beberapa transforman B. subtilis diperoleh 1 koloni rekombinan positif yang mengandung DNA target. Eksperimen integrasi kromosom menghasilkan pertumbuhan koloni pada media LB dengan berbagai konsentrasi eritromisin yaitu LB tanpa eritromisin, LB eritromisin 0,5 g/ mL, dan LB eritromisin 5 g/ mL. Analisis terhadap klona integran positif dilakukan dengan PCR genom, namun hasil penelitian menunjukkan belum didapatkan klona positif dari 60 klona yang tumbuh pada media LB tanpa eritromisin.

In addition, the lipase enzyme plays a role in various reactions, such as esterification, interesterification, and transesterification reactions. The present study was conducted to subclone the Baillus subtilis lipase gene lipA cloned in the pGEMlipA recombinant vector into pSKExynAQ1 recombinant vector by EMP method and to transform the resulted pSKExynlipA recombinant vector into Bacilus subtilis DB104. Megaprimer used in the EMP was synthesized by PCR using a pair of gen specific primer designed based on lipA and xynAq1 nucleotide sequencces so that the oligonucleotide is a comibantion of both nucleotide sequences, with pGEMlipA served as DNA template. The resulted PCR product was used as megaprimer for the EMP with the pSKExynAq1 recombinant vector served as DNA template. The resulted EMP product pSKExynlipA was used to transform E. coli DH5 . The recombinant vector was then extracted from E. coli to be transformed into B. subtilis DB104 by the method of protoplasting followed by integration of the lipase gen into the B. subtilis DB104 chromosome. EMP Cloning of the lipase gene into the pSKExynAQ1 vector has been successfuly conducted that resulted in specific band of 7849 bp. The EMP product was successfully transformed E. coli colonies grew on LB media containing ampicillin. Qualitiative selection of positive colonies using TBA tri butyric acid agar media resulted in 1 positive clone clone 1 that produed a clear zone. The recombinant plasmid has been successfully transformed into B. subtilis DB104 using protoplasting method. Analyzed recombinant with digestion using PstI restriction enzyme showed 1 colony as positive recombinant containing target DNA. The result of chromosome integration showed colonies growing on LB medium with various erythromycin concentrations, LB without erythromycin, LB erythromycin 0.5 g mL, and LB erythromycin 5 g mL. The isolat was analyzed with genomic PCR, and the results showed no positive isolates from 60 clones. "

"ABSTRAK
Pendahuluan :Trypanosoma evansi adalah protozoa berflagella yang bersirkulasi
di dalam darah secara ekstraseluler sebagai agen penyakit Surra serta menyerang
seluruh hewan vertebrata, serta berpotensi sebagai zoonosis. Informasi virulensi
isolat T. evansi sangat dibutuhkan untuk penentuan strategi pengobatan Surra di
daerah wabah dan endemis. Penelitian ini bertujuan untuk mengetahui variasi
virulensi isolat T. evansi yang dikoleksi dari berbagai wilayah di Indonesia
termasuk memperoleh marka genetik serta mengetahui profil sitokin pada mencit.
Disamping itu, dilakukan juga uji serologis pada peternak di daerah wabah Surra
Metode : Sebanyak 32 isolat lokal T. evansi dikonfimasi dengan PCR multiplex
(ITS-1; Te Ro Tat 1,2 VSG dan ESAG6/7), selanjutnya diuji virulensinya dengan
menginfeksikan104 parasit pada mencit galur DDY. Studi genotyping populasi
T. evansi dievaluasi dengan 8 marka mikrosatelit Tbb-1, Tbb-5, Tbb-9, Tbb-10,
MORF2-CA, M6C8-CA, MEST-19AT, MT3033-AT. Dua isolat yang berbeda
virulensi (tinggi-Bang87 dan rendah-Pml 287) dipilih untuk uji imunopatogenitas
sedangkan serum peternak diuji dengan metode FELISA dan CATT T. evansi.
Hasil : Dari 32 isolat tersebut terbagi menjadi 17 isolat bervirulensi tinggi, 11
isolat bervirulensi moderat dan 4 isolat bervirulensi rendah dengan 8 pola tingkat
parasitemia. Analisis Neigbour Joining (NJ) terhadap 8 lokus berdasarkan Multi
Lokus Genotipe (MLG) mikrosatelit terbagi menjadi 4 populasi, yaitu MLG A,
MLG B, MLG C dan MLG D. Analisis terhadap struktur populasi juga
memberikan hasil yang sama dengan terbentuknya 4 klaster. Hasil ini juga
membuktikan bahwa marka yang digunakan bersifat spesifik lokasi. Sebanyak
tiga marka mengindikasikan adanya asosiasi antara virulensi dan MLG (Tbb-1,
M6C8-CA dan MEST-19). Kadar IFN-γ meningkat secara tajam pada mencit
yang diinfeksi isolat Bang 87 pada 4hpi berkorelasi negatif yang signifikan
(p<0,05) dengan kadar IL-10, sedangkan pada mencit yang diinfeksi isolat Pml
287, peningkatan kadar IFNγ berkorelasi positif dengan kadar IL-10. Kematian
dini pada mencit yang diinfeksi isolat Bang 87 disebabkan oleh sindrom respon
inflamasi sitemik. Hasil uji serologis menunjukkan bahwa 4 dari 24 serum
peternak (16,67%) didaerah wabah positif dan seluruh serum negatif untuk
daerah non wabah.
Kesimpulan : Variasi virulensi T. evansi isolat Indonesia memiliki karakter
molekular yang berbeda serta menginduksi pola mediator sitokin pro dan
antiinflamasi yang berhubungan dengan pola manifestasi patologi yang berbeda.
Marka mikrosatelit pada studi ini mampu mengidentifikasi asal usul sumber
infeksi, dan tingkat virulensi isolat yang sedang bersirkulasi. Surra berpotensi
sebagai emerging zoonosis, terutama bagi peternak didaerah wabah dan endemis.

ABSTRACT
Introduction: Trypanosoma evansi is an extracellular homoflagellate of
protozoan blood causing Surra. The disease attacks all vertebrates and potentially
as zoonosis. Virulence analysis of T. evansi is a fundamental knowledge to
determine treatment strategies of Surra in both outbreak and endemic areas. The
aims of this study was to determine virulence variation of T. evansi isolates
collected from various regions in Indonesia and to obtained genetic markers as
well as cytokine profile in mice. In addition, serological test was also carried out
to farmers living in a Surra outbreak area
Methods: Total of 32 isolates of T. evansi corfirmed with multiplex PCR (ITS-1;
Te Ro Tat 1.2 VSG and ESAG6 / 7), were further tested with inoculation 104
parasite in DDY mice strain. The population genotype study of T. evansi was
evaluated with 8 microsatellite markers (Tbb-1, Tbb-5, Tbb-9, Tbb-10-CA
MORF2, M6C8-CA, MEST-19AT, MT3033-AT). Two different virulence
isolates, high-Bang87 and low-PML287 was selected to cytokine profile analysis
using ELISA, while farmers sera were tested using CATT and FELISA kits
Results: A total of 32 local isolates of T. evansi tested were divided into three
different virulences, i.e. 17 high virulence isolates, 11 moderate virulence and 4
low virulence isolates forming 8 pattern parasitemia levels. Based on Neigbour
Joining (NJ) on 8 Microsatellite Multilocus Genotype (MLGs) was grouped into
4 populations (MLG A, MLG B, MLG C and MLG D). Stucture population
analysis also provided the similar result generating 4 clusters. These results
indicated that the markers used in this study had a specific location property.
Three markers (TBB-1, and MEST M6C8-CA-19) showed an association
between virulence and MLG. IFN-γ levels increased significantly in mice
infected with Bang 87 isolate on 4th day post infection (dpi) having a significant
negative correlation (p <0.05) with increased IL-10 levels, whereas in mice
infected by PML 287 isolate, IFN-γ levels were positively correlated with IL- 10
levels. Early death in mice infected with Bang87 isolates was caused by systemic
inflammatory response syndrome (SIRS). Result of serological test showed that 4 out
of 24 farmers sera (16.67%) from outbreak areas are positive and all sample from
free area are negative.
Conclusion: Virulence variation of T. evansi isolates from Indonesia has
different molecular character and induces cytokine pattern of pro and antiinflammatory
mediators associated with distinct patterns of pathological
manifestations. The microsatellite markers found in this study are able to identify
origin of infection sources dan determine virulence of isolates that circulate on the
outbreak area. Surra is potential new emerging disease, particularly for farmers or
immunosurpressed individuals who living in both endemic and outbreak areas;Introduction: Trypanosoma evansi is an extracellular homoflagellate of

negative correlation (p <0.05) with increased IL-10 levels, whereas in mice
infected by PML 287 isolate, IFN-γ levels were positively correlated with IL- 10
levels. Early death in mice infected with Bang87 isolates was caused by systemic
inflammatory response syndrome (SIRS). Result of serological test showed that 4 out
of 24 farmers sera (16.67%) from outbreak areas are positive and all sample from
free area are negative.
Conclusion: Virulence variation of T. evansi isolates from Indonesia has
different molecular character and induces cytokine pattern of pro and antiinflammatory
mediators associated with distinct patterns of pathological
manifestations. The microsatellite markers found in this study are able to identify
origin of infection sources dan determine virulence of isolates that circulate on the
outbreak area. Surra is potential new emerging disease, particularly for farmers or
immunosurpressed individuals who living in both endemic and outbreak areas;Introduction: Trypanosoma evansi is an extracellular homoflagellate of
protozoan blood causing Surra. The disease attacks all vertebrates and potentially
as zoonosis. Virulence analysis of T. evansi is a fundamental knowledge to
determine treatment strategies of Surra in both outbreak and endemic areas. The
aims of this study was to determine virulence variation of T. evansi isolates
collected from various regions in Indonesia and to obtained genetic markers as
well as cytokine profile in mice. In addition, serological test was also carried out
to farmers living in a Surra outbreak area
Methods: Total of 32 isolates of T. evansi corfirmed with multiplex PCR (ITS-1;
Te Ro Tat 1.2 VSG and ESAG6 / 7), were further tested with inoculation 104
parasite in DDY mice strain. The population genotype study of T. evansi was
evaluated with 8 microsatellite markers (Tbb-1, Tbb-5, Tbb-9, Tbb-10-CA
MORF2, M6C8-CA, MEST-19AT, MT3033-AT). Two different virulence
isolates, high-Bang87 and low-PML287 was selected to cytokine profile analysis
using ELISA, while farmers sera were tested using CATT and FELISA kits
Results: A total of 32 local isolates of T. evansi tested were divided into three
different virulences, i.e. 17 high virulence isolates, 11 moderate virulence and 4
low virulence isolates forming 8 pattern parasitemia levels. Based on Neigbour
Joining (NJ) on 8 Microsatellite Multilocus Genotype (MLGs) was grouped into
4 populations (MLG A, MLG B, MLG C and MLG D). Stucture population
analysis also provided the similar result generating 4 clusters. These results
indicated that the markers used in this study had a specific location property.
Three markers (TBB-1, and MEST M6C8-CA-19) showed an association
between virulence and MLG. IFN-γ levels increased significantly in mice
infected with Bang 87 isolate on 4th day post infection (dpi) having a significant
negative correlation (p <0.05) with increased IL-10 levels, whereas in mice
infected by PML 287 isolate, IFN-γ levels were positively correlated with IL- 10

"Kromosom merupakan substansi genetik pada makhluk hidup yang diwariskan ke generasi selanjutnya. Kromosom terbentuk melalui proses kondensasi selama siklus sel. Faktor-faktor yang mempengaruhi kondensasi kromosom adalah protein scaffold dan kation divalen, terutama ion kalsium (Ca2+). Peran ion kalsium terhadap kromosom masih terbatas pada kromosom manusia dan belum pernah dilaporkan pada kromosom tumbuhan. Tujuan penelitian ini untuk mengetahui peran ion kalsium terhadap struktur kromosom barley menggunakan mikroskop fluoresens dan scanning electron microscope. Kromosom barley diisolasi kemudian diberi perlakuan 1 mM BAPTA sebagai agen pengikat ion kalsium dan PBS sebagai kontrol. Terdapat perbedaan panjang dan struktur kromosom barley setelah diberikan perlakuan 1 mM BAPTA dibandingkan dengan kromosom kontrol. Kromosom kontrol memiliki panjang rata-rata 5,3 μm dengan struktur kromosom yang padat, sedangkan kromosom dengan perlakuan BAPTA memiliki panjang rata-rata 10,7 μm dengan struktur kromosom lebih renggang dan kurang padat. Hasil tersebut menunjukkan bahwa ion kalsium memiliki peranan penting dalam menjaga struktur kromosom barley.

Chromosomes are genetic substances in living organisms that are passed on to the next generation. Chromosomes are formed through the process of condensation during the cell cycle. Factors that influence chromosome condensation are scaffold proteins and divalent cations, especially calcium ions (Ca2+). The role of calcium ions on chromosomes is still limited to human chromosomes and has never been reported on plant chromosomes. The purpose of this study was to determine the role of calcium ions on the structure of barley chromosomes using a fluorescence microscope and scanning electron microscope. The barley chromosome was isolated and then treated with 1 mM BAPTA as a calcium ion chelating agent and PBS as a control. According to the data obtained, there are differences in length and structure of barley chromosomes after being treated with 1 mM BAPTA compared to control chromosomes. The control chromosome has an average length of 5.3 μm with a compact chromosome structure and chromosomes with BAPTA treatment have an average length of 10.7 μm with a less condense chromosome structure. These results indicated that calcium ions have an important role on maintaining the structure of barley chromosomes."
