Abstract

Penyakit Demam Berdarah Dengue (DBD) disebabkan oleh infeksi virus dengue yang dibawa Aedes aegypti (Ae. aegypti) sebagai vektor primernya. Pengendalian vektor pada penyakit DBD masih belum maksimal. Selain itu vaksin yang belisensi untuk penyakit DBD masih belum dilaporkan. Melalui pengembangan TBV salah satunya dengan memanfaatkan komponen saliva vektor. aliva vektor memiliki potensi dalam meningkatkan transmisi patogen ke tubuh inang, maka perlu adanya karakterisasi molekul dalam saliva nyamuk termasuk faktor imunomodulator. Karakterisasi faktor imunomodulator saliva Ae. aegypti dilakukan melalui uji reaksi silang antara protein kelenjar saliva Ae. aegypti dengan beberapa plasma darah manusia. Hasil penelitian menunjukkan adanya protein spesifik yang dikenali antibodi dalam plasma darah orang endemik dengan berat molekul ~ 37 kDa. Hal ini megindikasikan bahwa di dalam tubuh penduduk endemik telah mengembangkan antibodi anti-saliva Ae. aegypti yang diduga berperan penting dalam resistensi terhadap infeksi virus dengue.

Abstract

Malaria is still a major problem for developing countries, including Indonesia. One approach to overcome this disease is prevention by vaccination. However, there is still no effective malaria vaccine that is applicable. The ideal malaria vaccine is a combination vaccine that can prevent the pre-erythrocytic cycle, the erythrocytic cycle and transmission process. Salivary vector-based vaccine has the potential to be developed as a malaria vaccine because it can prevent transmission process and also decrease the morbidity of the disease. Saliva from Anopheles contains vasomodulator and immunomodulatory components, that are required in the blood feeding process, but in the same time it could enhance the transmission of the malaria parasite. If the component in the salivary vector can increase pathogen infection, then vaccinating the host with its anti-substances can control the transmission of pathogens (Transmision Blocking Vaccine). Anopheles sundaicus is an important vector of malaria in coastal areas of Java, Bali, Sumatra, Kalimantan and West Nusa Tenggara islands. Repeated exposures of Salivary Gland Extract (SGE) from this vector have been proven to be able to decrease parasitemic rates in mouse model for malaria in our study. The objective of this research is to determine and localize the immunogenic protein from SGE of An. sundaicus as the first step for the characterization of its immunomodulatory component. Mosquito salivary gland protein profile of An.sundaicus was determine by SDS-PAGE. Determination of salivary glands immunogenic proteins was conducted by Western Blotting with IgG from people living from endemic area as primary antibody. Out of 15 bands appeared in SDS PAGE ranging from 24 kD to 138 kD, only two protein bands with  molecular weights of 68 and 37 kDa were the most immunogenic. Those immunogenic proteins were consistent recognized by pooled serum of people as well as by individual response. Keywords: malaria, saliva, vector, immunogenic protein, vaccine

Abstract

A blood clot (thrombus) in a blood stream is formed due to a circulatory system imbalance in the hemostasis which results in plug of blood vessels. The suppliy of nutrients and oxygen to the tissues is inhibited (ischemia) by the accumulation of thrombus and embolus in the blood vessel. This prosses is the main cause for further atherotrombotic diseases such as myocardial infraction and cerebral infraction. This disease could be overcome by thrombolytic therapy by using fibrinolytic protease enzyme. Fibrinolytic activity of protease enzymes have been studied from various species of bacteria. Bacterial isolate of WU 021055* obtained from Papuma coastal waters has demonstrated fibrinolytic activity. This research was aimed to identify the bacterial isolate through morphological characterization (colony and cell morphology), physiological characterization (indole test, carbohydrates fermentation test (glucose, lactose, sucrose and fructose), catalase test, starch hydrolysis test, and the pH effect test), and molecular identification using 16S rRNA. Based on those characterizations, the bacterial isolate of WU 021055* shows a high similarity to Bacillus aerius.Keywords: Atherotrombosis, fibrinolytic, identification, characterization, bacteria ABSTRAKBekuan darah (trombus) dalam peredaran darah terbentuk akibat ketidakseimbangan sistem sirkulasi dalam hemostasis yang menyebabkan penyumbatan pembuluh darah.

Abstract

Purification of 31 and 56 kDa Immunogenic Proteins from the Salivary Glands of Aedes aegyptiThe salivary gland of arthropod vector contains various bioactive compounds and plays a role in the transmission of pathogens to the host. The host develops anti-salivary antibodies against vector saliva exposure. Our previous research has identified two immunogenic proteins with molecular weights of 31 and 56 kDa from the Aedes aegypti salivary gland protein extract. However, the role of the 31 and 56 kDa immunogenic proteins from saliva Ae. aegypti is not fully known, so it is necessary to purify two immunogenic protein fractions to better specify the target of developing a dengue vaccine. This study aimed to purify the 31 and 56 kDa immunogenic protein fractions by electroelution and dialysis methods. The purification of the two protein fractions has been successful which were confirmed by the SDS-PAGE by the existence of single-band parallel to the positive control. These results were further supported by the dot blot analysis which showed a positive reaction in the form of dark spots in the two protein fractions which were reacted with dengue patients' serum, endemic healthy people, and neonates. These results indicated that the purified 31 and 56 kDa immunogenic protein fraction can be identified by specific antibodies.Keywords: dialysis, electroelution, immunogenic, purification, saliva  ABSTRAKKelenjar saliva vektor arthropoda mengandung berbagai senyawa bioaktif dan berperan dalam transmisi patogen ke tubuh inang.

Abstract

BackgroundDengue virus is transmitted by several species of Aedes mosquitoes, with Aedes albopictus as secondary vector. During blood feeding, these vectors inject saliva into the vertebrate hosts. The saliva contains anticoagulant, anti-inflammatory and immunogenic factors. The objective of this research was to detect immunogenic proteins from Ae.albopictus salivary glands reacting with sera of people living in dengue endemic areas. MethodsThe identification of immunogenic proteins of Ae. albopictus salivary gland used one-dimensional gel electrophoresis (sodium dodecyl sulfate polyacrylamide gel electrophoresis), and western blot analysis, respectively. To determine the immunogenic nature of the candidate proteins, the antigens from the salivary gland of Ae. albopictus were reacted with sera from healthy persons, dengue hemorrhagic fever (DHF) patients, and neonates, each of the groups comprising 10 samples. ResultsThe protein profiles of Ae. albopictus salivary glands showed 13 bands with molecular weights from 16 kDa up to 97 kDa, i.e. 16, 17, 26, 28, 31, 32, 45, 55, 60, 67, 73, 76, and 97 kDa. According to western blot analysis result, the 31 kDa proteins were recognized in all endemic population sera, both in DHF patients and healthy persons. In contrast, protein bands of 47 and 67 kDa were only recognized by the sera of DHF patients. ConclusionThree immunogenic proteins of 31, 47 and 67 kDa were detected from Ae. albopictus salivary glands. These immunogenic proteins may be developed as candidate biomarkers for bite exposure to Ae. albopictus and as vector-based DHF vaccines.

Abstract

Bacteria are the most dominant group of microorganisms in aquatic environments due to their role in organic matter decomposition. Decomposition activity is related to the type  and dominance of bacteria in the communities. Therefore, study of bacterial diversity is an important step to understand their role in aquatic ecosystems. This study was to determine bacterial diversity and their physiological characters of bacteria from Bandealit Coast in Jember East Java Indonesia. The bacteria were confirmed by BOX-PCR profile for their genetic polymorphisms. Identification of potential isolate was conducted based on 16S rRNA gene sequence. The result showed that BA011109 isolate was able to utilize D-cellobiose as a sole substrate, indicating its ability to hydrolyse b-glucoside bond. This isolate was a potential decomposer in the area considering that most of organic pollutants were from plants that cointain high cellulose. Based on its 16S rRNA gene sequence, this isolate was closely related to Microbacterium esteraromaticum with 100% homology. Further study on quantitative hydrolytic activities is needed to elucidate its role as an organic matter decomposer in aquatic environment.

Abstract

Kabupaten Banyuwangi merupakan salah satu daerah endemis malaria, khususnya Desa Bangsring Kecamatan Wongsorejo. Berdasarkan laporan survei entomologi, di desa tersebut terdapat lagun yang digunakan sebagai tempat perindukan Anopheles. Penelitian ini bertujuan untuk mengamati beberapa karakteristik bionomik yang penting yaitu identifikasi spesies serta perilaku dan preferensi menghisap darah. Sampling dilakukan pada bulan Mei sampai bulan November2015, pada minggu ke 2 setiap bulannya. Penangkapan nyamuk dilakukan pada Manusia Dalam Rumah dan Manusia Luar Rumah di dua rumah berbeda. Masing-masing penangkapan setiap 40 menit, dimulai pukul 18.00 sampai 06.00. Penangkapan nyamuk yang Istirahat Dalam Rumah (IDR) dan Istirahat di Sekitar Kandang Ternak (ISKT) setiap 10 menit pada waktu yang sama. Hasil identifikasi menunjukkan spesies Anopheles yang dominan di lokasi penelitian adalah An. sundaicus. Beberapa spesies lainnya yang ditemukan diantaranya adalah An. vagus, An. subpictus, An. barbirostris dan An. indefinitus. Aktivitas mengigit Anopheles mengalami puncak kepadatan antara pukul 21.00 – 22.00. Sementara itu preferensi mengigitnya lebih bersifat eksofagik dan zoofilik. Hal ini dapat merupakan penyebab menurunnya kasus malaria di daerah tersebut selama 3 tahun terakhir semenjak terjadinya kejadian luar biasa malaria pada tahun 2011 dengan jumlah kasus sebanyak 107 kasus malaria.
