Abstract

AbstrakPenyakit Campak disebabkan oleh virus campak yang termasuk genus Morbilivirus dan Family Paramyxoviridae. Penyakit campak masih menjadi masalah kesehatan karena masih ditemukan Kejadian Luar Biasa (KLB) di Indonesia. Salah satu penyebab terjadinya KLB tersebut diduga sebagaiakibat perbedaan antigenesitas antara strain vaksin yang digunakan dengan strain virus campak liar yang beredar di Indonesia. Penelitian ini bertujuan mendapatkan gambaran tentang karakteristik genetik gen Haemagglutinin virus campak liar yang ada di Indonesia. Spesimen yang digunakan sebanyak 27 isolat virus penyebab KLB dari 17 propinsi selama periode tahun 2003-2010. Isolat virus dilakukan pemeriksaan secara RT-PCR dan sekuensing dengan metode Sanger. Hasil sekuensing dianalisis dengan menggunakan perangkat lunak Bioedit 7.0 dan MEGA 4.0. Hasil penelitian didapatkan perbedaan 10 asam amino antara virus campak strain vaksin CAM-70 dan virus campak liar pada posisi D416N; K424T; V451M; N455T; V466I; I473T; F476L; Y481S atau Y481N; H495N; G505D. Kesimpulan penelitian ini adalah terdapat perbedaan karakteristik genetik antara virus campak liar di Indonesia berbeda dengan strain virus vaksin CAM-70.Kata kunci : Campak, Analisis Molekuler, Hemagglutinin, CD46AbstractMeasles is caused by virus belonging to the genus Morbilivirus and Family Paramyxoviridae.

Abstract

Candida spesies is important cause of nosocomial infection that lead to death and prolonged hospital stay. Guideline management of candidiasis by Infectious Diseases Society of America (IDSA) in 2009 proposed early antifungal therapy in critical patient with the risk of invasive candidiasis. Early identification of  sepsis patien with high risk of fungal infection is challenging because  long and low result from blood culture. Antifungal usage without appropriate indication can cause resistance to antifungal. The aim of the study is obtain data candida species that caused candidemia in Cipto Mangunkusuno hospital (RSCM) and sensitivity pattern to antifungal. This retrospective study used patient medical record from 2011-2014. This study had 117 candidemia case in RSCM during 2011-2014. Every year candidemia was dominated by Candida  tropicalis, Candida  albicans, and Candida  parapsilosis with trend the increase number of Candida  tropicalis since 2013. Susceptibility pattern of Candida that cause candidemia in RSCM from 71 isolat tested the result was86% spesies Candida flukonazol sensitive, 99% vorikonazol sensitive, 97% amfoterisin B sensitive and 100% flusitosin sensitive.

Abstract

Objective: To analyze level of retinol deposit sufficiency in the natural history of cervical cancer. Methods: Serum retinol level was measured by ELISA from peripheral blood of subjects with normal cervix, cleared and persistent high risk human papilloma virus (HR-HPV) subclinical infection, and cervical cancer who fulfilled the inclusion and exclusion criteria. The study was held in Dr. Cipto Mangunkusumo and Fatmawati Hospital, Jakarta, within 2 years (August 2013- 2015). Blood was taken twice, consisting of post-8-hour fasting blood and 2 hours after 6000 IU retinyl palmitate oral administration. Results: Of 47 total samples, sufficient level of retinol deposit in normal cervix, cleared and persistent HR-HPV subclinical infection, and cervical cancer group was 85.0% (reference), 75.0% (OR 1.89), 33.3% (OR 11.33), and 75% (OR 1.89); respectively. Statistically, there was no significant difference from sufficiency level of retinol deposit between normal cervix and clearance HR-HPV subclinical infection (p=0.628), normal cervix and persistent HR-HPV subclinical infection (p=0.078), normal cervix and cervical cancer (p=0.433), cervical cancer and clearance HR-HPV subclinical infection (p=1.000), cervical cancer and persistent HR-HPV subclinical infection (p=0.430), persistent and clearance HR-HPV subclinical infection group (p=0.740). Conclusion: This study proves that normal cervix group has the highest level of retinol deposit sufficiency; however, it cannot be stated that cervical cancer group has less sufficiency level. Persistent HR-HPV subclinical infection group has the lowest level of retinol deposit (OR 11.33). There is no association between sufficient level of retinol deposit and clearance of HR-HPV.

Abstract

The H5N1 influenza virus in Indonesia has caused more than 100 people died due to the virus infections.  Cases in humans were mostly due to the virus spread from the infected birds. This study characterized molecularly the H5N1 virus from birds around the H5N1 infection cases in humans in Indonesia. Result from this study revealed that in several cases, waterfowl species could become the source of H5N1 infections in human. We found that the one of six viruses used in this study probably was a first antigenic shift virus in Indonesia. This study shows that the AI viruses isolated from birds around humans infected by H5N1 virus has specific characteristics namely the presence of several amino acid substitutions especially on the M1 and M2 proteins. The substitutions are similar in most of H5N1 human cases in Indonesia.

Abstract

Diagnosis of Neisseria gonorrhoeae infection is needed for patient therapy and for reducing this bacterial transmission in the population. The culture method is a gold standard method for N. gonorrhoeae detection, however it has low sensitivity. Among molecular methods with high sensitivity and specificity, SYBR Green real-time PCR is the potential method for N. gonorrhoeae detection. In this study, we developed an SYBR Green real-time PCR-based system assay for N. gonorrhoeae detection. Several PCR conditions were optimized and analyzed including primer annealing temperature, DNA template volume, the limit of detection (LoD), cross-reaction with others (bacteria, viruses, fungus, protozoa), and quality assurance. The results showed that the annealing temperature and DNA template volume were 60oC and 5 µL, respectively. The LoD was 29 DNA copies corresponding to 3 bacterial cells per reaction. No cross-reaction was detected for other bacteria, viruses, fungus and protozoa. The external quality assurances enrolled in 2019 and 2021 showed 100% concordance. The preliminary testing for clinical samples was also 100% concordance. In conclusion, the SYBR Green real-time PCR-based system assay developed in this study is promising for application in clinical laboratories.

Abstract

The avian influenza A H5N1 outbreaks started in 2003 and Indonesia introduced a vaccination campaign in 2004 to control the disease. In 2007, anecdotal reports about reduced vaccine effectiveness were received from commercial farmers. This paper describes the evolution of viruses in Indonesia up till 2008 and focus on viruses from vaccinating farms reporting vaccine failure were compared to viruses isolated from outbreak areas with no vaccination program. Result of the study revealed that viruses from vaccinated chickens had more extensive mutation at the HA molecule compared to chicken and other avian species without vaccination. Substitutions occurred at the HA gene level as well as at NA, M1 and NS1 genes. Viruses isolated and characterized form 2008 vaccinated flocks had substitutions that were unique and different with the old viruses. The recommendation arising from this study to the avian influenza disease control program in Indonesia is that continuous monitoring of genetic character of viruses and the vaccine seed strain should be updated periodically and matched with the virus circulated in the field.

Abstract

Nine HA genes of influenza A (H1N1) viruses originating from swine which were detected in 2009 in Jakarta, Indonesia, were characterized in this study. Nasopharyngeal and/or pharyngeal samples were extracted to obtain viral RNA genomes. Amplification of the HA segment was performed by using the reverse transcription-polymerase chain reaction (RT-PCR), and followed by nested PCR in cases of RT-PCR negative. DNA sequencing was performed by using eight overlapping primers. All the Jakarta strains were closely related to vaccine strain A/California/07/2009. Nine amino acid changes were found in the Jakarta strains, and 5 (P100S, S220T, G239D, R240Q, and I338V) of those were unique to all Jakarta strains with respect to strain A/California/07/2009 used to produce vaccine. An I338V substitution was detected in a cleavage site of HA and no amino acid changes were detected in potential sites for N-linked glycosylation. For seven sites (positions 131, 158, 160, 183, 187, 222, and 227) playing an important role in viral attachment to host receptor, none of the expected amino acid changes was detected; however, a S220T substitution close to amino acid 222 was found in all the Jakarta strains. All amino acid changes potentially affect the pathogenicity of the viruses and the efficacy of strain A/California/07/2009 in neutralizing the Jakarta strains.

Abstract

The endogenous HIV-1 vaccine based on Gag protein is expected to stimulate the immune response of CD8+ T cells (cytotoxic). The Gag protein that has been produced by the E.coli prokaryote system is an exogenous antigen. The fusion of VP22 protein is expected to deliver Gag antigen into the cytoplasm of cell, observed by eGFP markers. Sequences of VP22 (114 pb), GagHIV-1 (1506 pb), and eGFP (733 pb) were inserted into the pQE80L, respectively. The recombinant protein was expressed in the E.coli system and purified by the Ni-NTA method. Antigen delivery fused with VP22 and eGFP was observed with fluorescence and confocal microscopy. The recombinant plasmid constructs of protein expression eGFP, VP22-eGFP, GagHIV-1-eGFP, VP22-GagHIV-1-eGFP were verified by DNA sequencing according to the reference. The recombinant plasmid constructs of Gag HIV-1-eGFP and VP22-GagHIV-1-eGFP still need to be optimized so they can be expressed in the E.coli system. The recombinant protein VP22-eGFP (27.02 kDa) was succesfully obtained and fluorescent green (entered) into the cytoplasm and nucleus of vero cells. In addition to the HIV-1 vaccine, this recombinant plasmids pQE80L-eGFP and pQE80L-VP22-eGFP also have the potential to be used as tools in the development of endogenous vaccines for another viruses/microbes. Abstrak Vaksin endogen HIV-1 berbasis protein Gag diharapkan dapat menstimulus respons imun sel T CD8+ (sitotoksik). Protein Gag yang telah diproduksi dengan sistem prokariota E.coli merupakan antigen yang bersifat eksogen. Fusi protein VP22 diharapkan mampumenghantarkan antigen Gag masuk ke sitoplasma sel, diamati dengan marker eGFP. Sekuens VP22 (114 pb), GagHIV1 (1506 pb), dan eGFP (733 pb) telah diinsersikan pada vektor pQE80L. Protein rekombinan diekspresikan pada sistem E.coli dan dipurifikasi dengan metode Ni-NTA. Penghantaran antigen yang difusikan dengan VP22 dan marker eGFP diamati dengan mikroskop fluoresens dan konfokal. Konstruksi plasmid rekombinan pengekspresi protein eGFP, VP22-eGFP, GagHIV1-eGFP, dan VP22-GagHIV1-eGFP telah diverifikasi dengan sekuensing DNA sesuai dengan sekuen referensi. Plasmid rekombinan pengekspresi GagHIV1-eGFP dan VP22-GagHIV1-eGFP masih perlu dioptimasi agar dapat diekspresikan di sistem E.coli. Protein rekombinan VP22-eGFP (27,02 kDa) telah berhasil diperoleh serta berpendar fluoresens hijau (masuk) ke sitoplasma dan nukleus sel vero. Selain vaksin HIV-1, plasmid rekombinan pQE80L-eGFP dan pQE80L-VP22-eGFP juga berpotensi dapat digunakan sebagai ‘tools’ dalam pengembangan vaksin endogen dari virus atau mikroba lainnya.
