Abstract

Human Immunodeficiency Virus (HIV) is an RNA virus. It is a lentivirus, a retrovirus member family which causes Acquired Immunodeficiency Syndrome (AIDS). An early event in every retroviral multiplication is the integration of the viral double-stranded DNA genome into the host chromosome. The integration is facilitated by the activation of integrase.The goal of this research is to obtain the HIV integrase encoding gene. The obtained integrase ORF was intended to be cloned into cloning vector pJETclone and to transform Escherichia coli JM109. The cDNA synthesis was conducted by reverse transcription by converting the RNA genome to DNA. The obtained cDNA was amplified by Polymerase Chain Reaction (PCR) technique to obtain integrase encoding gene. The PCR product was inserted into the plasmid using blunt ended cloning system and was characterized using DNA gel electrophoresis and nucleotide analysis. The DNA gel electrophoresis of PCR product showed the expected band. Further characterization was conducted using nucleotide sequencing showed that the PCR product was homologue to HIV-1 integrase from Indonesia. The PCR was performed on the cloned showed DNA insert on expected size. The nucleotide analysis was conducted on the pure recombinant plasmid, the DNA was read properly.Key words: HIV-1,Iintegrase, E.coli JM109 AbstrakHIV (Human Immunodeficiency Virus) adalah virus RNA, dan termasuk ke dalam lentivirus, anggota kelompok retrovirus yang menyebabkan penyakit AIDS Acquired Immunodeficiency Syndrome. Tahap awal multiplikasi setiap retrovirus adalah integrasi genom DNA untai ganda virus ke dalam kromosom inang. Tahap integrasi ini difasilitasi oleh aktivasi enzim integrase. Tujuan penelitian ini adalah untuk memperoleh DNA pengkode integrase HIV. Kerangka baca terbuka atau Open Reading Frame (ORF) pengkode integrase yang diperoleh diklon ke vektor kloning pJETclone dan digunakan untuk mentransformasi Escherichia coli JM109. Sintesis cDNA dilakukan dengan mentranskripsi balik genom RNA menjadi DNA yang selanjutnya digunakan sebagai templat untuk amplifikasi ORF pengkode integrase dengan teknik reaksi polimerisasi berantai atau Polymerase Chain Reaction (PCR). Produk PCR selanjutnya disisipkan kedalam plasmid menggunakan sistem kloning blunt-ended dan dikarakterisasi dengan elektroforesis DNA dan analisis nukleotida. Analisis dengan elektroforesis DNA menunjukkan bahwa produk PCR berukuran sesuai dengan ukuran teoritis. Karakterisasi lebih lanjut dengan teknik analisis nukleotida menunjukkan produk PCR tersebut homolog dengan integrase HIV-1 dari Indonesia. Teknik PCR juga dilakukan terhadap klon, dan adanya produk PCR berukuran sesuai dengan ukuran teoritis menunjukkan adanya DNA sisipan. Analisis nukleotida dilakukan pada plasmid rekombinan murni dan DNA terbaca dengan baik.Keywords: HIV-1,Integrase, E.coli JM109

Abstract

BackgroundCysticercosis is an infectious disease caused by the larval form of Taenia solium (cysticercus cellulosae) and has been ranked as the most important food-borne parasite of humans in terms of public health, socioeconomic and trade impact. Cysticercosis is still a health problem in Papua and is inseparable from socio-cultural factors, hygiene and environmental sanitation. The aim of this study was to investigate the seroprevalence of cysticercosis and the risk factors that contribute to cysticercosis.MethodsA cross-sectional study was conducted in March-November 2016 involving 800 subjects. Demographic data and risk factors were collected using questionnaires. Cysticercosis serological examination was performed by means of the magnetic microsphere bead immunoassay technique coupled with rT24H recombinant protein to detect serum rT24H cysticercosis specific antibodies. The data obtained were analyzed by bivariate test (chi-square) and logistic regression.ResultsCysticercosis seroprevalence in Papua was 3.6% (284/7 874). The logistic regression analysis found that the risk factors playing the role of predictor were cooking pork with hot stones [OR=3.06; 95%CI: 2.19-4.28; p=0.000], nail hygiene [OR=2.05; 95%CI: 1.57-2.67; p=0.000], consumption of raw vegetables or salads [OR=0.52; 95%CI: 0.30-0.91; p=0.022], use of river water for washing foods [OR= 1.92; 95%CI: 1.39-2.64; p=0.000].ConclusionsCooking pork with hot stones was the main risk factor of cysticercosis. Suspected cases of T. solium in pigs should be confirmed by molecular methods. Both taeniasis and human cysticercosis should be notifiable and surveillance in animals should be improved.
