Banda Aceh

One of vector borne deseases which still remains a health problem in Indonesia is dengue fever (DBD). This desease is caused by dengue virus transmitted by Aedes aegypti mosquitoes. One of cities which is endemic for DBD in 2014 was Banda Aceh. The indicator for DBD endemic is based on entomology index. One of entomology index to be measured is the number of mosquito larvae-free. To know the status of mosquito larvae-free number in Banda Aceh, a suvey has been conducted in three subdistricts within Banda Aceh city, namely Banda Raya (Lamlagang village), Ulee Kareng (Ceurih village), and Baiturrahman (Peuniti village). A survey was conducted in 100 houses of every subdistrict. The total of 300 houses were investigated. From 300 houses investigated, there were 158 houses were positively had mosquito larvae. From 860 containers that were found and checked in those three subdistricts, it was found that there were 235 containers were positively contained mosquito larvae. The container which contained mosquito larvae dominantly was bathups inside the houses, there were 48,22% of larvae and 60,47% of pupas. The results showed that the number of mosquito larvae-free for Banda aceh was 47,33% which indicated that it was still below the number of national larvae-free that is > 95%. Therefore, Banda Aceh is still in a high risk of DBD transmission in the future.

Abstract: Dengue virus is a single-stranded RNA virus that belongs to Flaviviridae family. This virus causes dengue fever which is transmitted by Aedes aegypti dan Aedes albopictus. There are four serotypes of dengue virus; all of them can cause dengue fever. Understanding the genomics of dengue virus is important for research and diagnostics. The genome of dengue virus is 11 kilo-base long. It consists of 5’-untranslated region (5’-UTR), three structural genes (coding capsid protein, pre-membrane/membrane, and envelope), seven non-structural genes (coding NS1, NS2A, NS2B, NS3, NS4A, NS4B, and NS5 proteins) and 3’-UTR. Non-structural genes are encoding proteins of viral RNA replication, interferon response, viral assembly and secretion, endoplasmic reticulum membrane invagination induction, immune-mediator induction, and RNA 5’-caping.Keywords: dengue virus, genome, structural genes, non-structural genes, untranslated region.Abstrak: Virus dengue merupakan virus RNA beruntai tunggal yang termasuk dalam famili Flaviviridae.

AbstractAedes aegypti is the vector of some of the most important vector-borne diseases like Dengue, Chikungunya, Zika and Yellow fever, affecting millions of people worldwide. The cellular processes that follow a blood meal in the mosquito midgut are directly associated with pathogen transmission. We studied the homeostatic response of the midgut against oxidative stress, as well as bacterial and dengue virus (DENV) infections, focusing on the proliferative ability of the intestinal stem cells (ISC). Inhibition of the peritrophic matrix (PM) formation led to an increase in ROS production by the epithelial cells in response to contact with the resident microbiota, suggesting that maintenance of low levels of ROS in the intestinal lumen is key to keep ISCs division in balance. We show that dengue virus infection induces midgut cell division in both DENV susceptible (Rockefeller) and refractory (Orlando) mosquito strains. However, the susceptible strain delays the activation of the regeneration process compared with the refractory strain. Impairment of the Delta/Notch signaling, by silencing the Notch ligand Delta using RNAi, significantly increased the susceptibility of the refractory strains to DENV infection of the midgut. We propose that this cell replenishment is essential to control viral infection in the mosquito. Our study demonstrates that the intestinal epithelium of the blood fed mosquito is able to respond and defend against different challenges, including virus infection. In addition, we provide unprecedented evidence that the activation of a cellular regenerative program in the midgut is important for the determination of the mosquito vectorial competence.

Abstract Dengue fever is a vector-borne disease with Aedes aegypti as the main vector. Vector controls currently depended on insecticide. Considering the negative effect of insecticide, Sterile Insect Technique (SIT) was developed. This study was conducted to evaluate the effect of gamma-ray irradiation on the productivity of male Ae. aegypti. Male pupae age less than 15 hours were irradiated with 60 Gy and 70 Gy gamma-ray. When the pupae became adult, the sterile males mated with the same age females Aedes aegypti. Observation on fecundity, hatchability, and age was carried out until the second generation. Gamma-ray irradiation with the dose of 60 Gy and 70 Gy showed different effects on fecundity, egg hatchability, the emergence of the adult, and age of Aedes aegypti compared to control. Abstrak Demam berdarah merupakan penyakit tular vektor  yang sampai saat ini masih menjadi masalah kesehatan secara global. Vektor utama yang berperan pada penyebaran penyakit DBD yaitu nyamuk Aedes aegytpi. Pengendalian vektor saat ini sangat bergantung pada penggunaan insektisida. Dampak negatif penggunaan insektisida menyebabkan pengembangan pengendalian vektor yang lain diantaranya yaitu Teknik Serangga Mandul (TSM). Penelitian ini dilakukan untuk menganalisis produktivitas Ae. aegypti jantan iradiasi hingga generasi kedua. Pupa jantan umur <15 jam diradiasi sinargamma dosis 60 Gy dan 70 Gy. Setelah menjadi nyamuk jantan dewasa segeradikawinkan dengan nyamuk betina tidak iradiasi dengan umur yang sama. Pengamatan dilakukan terutama terhadap fekunditas, daya tetas, kemunculan nyamuk, dan umurnyamuk hingga generasi kedua. Iradiasi sinar gamma dosis 60 Gy dan 70 Gymenghasilkan dampak yang berbeda terhadap fekunditas, daya tetas telur, kemunculan nyamuk dan umur nyamuk bila dibandingkan dengan kontrol.

Demam Berdarah Dengue (DBD) perlu mendapat perhatian serius karena masih menjadi masalah kesehatan di Indonesia dan di beberapa daerah masih sering terjadi kejadian luar biasa. Di Jawa Tengah, kasus DBD cenderung meningkat setiap tahunnya terutama pada tahun 2012. Penelitian ini bertujuan menganalisis parameter entomologi dan menggambarkan jenis tempat penampungan air. Penelitian dilakukan di Kabupaten Grobogan, Purbalingga, Kendal dan Kota Semarang pada bulan Juni - Oktober 2013 desain potong lintang. Survei jentik dilakukan untuk melihat keberadaan tempat penampungan air pada 100 rumah. Masing-masing kabupaten dipilih tiga lokasi desa endemis DBD. Hasil survei digunakan untuk menghitung nilai parameter entomologi. Hasil penelitian menunjukkan bahwa meningkatnya kasus DBD di empat kabupaten/kota terkait dengan keberadaan vektor A. aegypti. Hal ini dibuktikan dengan masih tingginya persentase jumlah rumah yang ditemukan jentik A. aegypti (House Index > 10%) serta tingginya jumlah kontainer ditemukan jentik A. aegypti pada rumah yang dilakukan survei (Breteau Index). Nilai ovitrap index paling tinggi di Desa Kalikabong Kabupaten Purbalingga sebesar 40%. Proporsi controllable site lebih banyak daripada disposable site, berarti rumah tersebut berisiko tinggi sebagai tempat perkembangbiakan nyamuk.Dengue Haemorrhagic Fever (DHF) needs serious attention because it is still a health problem in Indonesia and in recent area DHF caused outbreak. In Central Java, incidence of DHF high every years, especially in 2012. This study aimed to analyze the parameters of entomology and describe types of containers. The study was conducted in Grobogan, Purbalingga, Kendal District and Semarang City in June _ October 2013 with cross-sectional design. Larvae survey had been done in 100 houses in three villages that endemic DHF at every district/city. The survey results are used to calculate parameter entomology. The results showed that existance of DHF cases in four district/city connected with the population of A. aegypti. This matter proved with high percentage of houses that found A. aegypti (House Index > 10%) and the high of container that containing A. aegypti in every houses (Breteau Index). The high of ovitrap index (OI) was 40% in Kalikabong village, Purbalingga district. The proportion of controllable sites more than disposable sites, meaning the house as the high risk of mosquito breeding sites.

DBD is an infectious disease by the Dengue virus, which is transmitted through the bite of Aedes aegypti mosquitoes. This disease's characteristics include sudden high fever accompanied by bleeding manifestations and the tendency to cause shock that can cause death. Until now, there is no cure for dengue fever or a vaccine. So the only way to prevent this disease is to break the chain of transmission. The main factor of dengue fever in Indonesia is the Aedes aegypti mosquito. Another way to avoid dengue fever is the correct 3M plus method, namely 1. Close, cover all places that can hold water, both inside and outside the house. 2. Drain, drain water reservoirs such as bathtubs, aquariums, and flower vases two times a week. The mosquito metamorphosis cycle, from egg to adult mosquito, lasts 8-10 days. 3. Bury. Bury all objects that can hold water, such as used cans or plastic containers. However, in the 3M movement, which has been renewed to 3M plus, this third M is no longer recommended because it can cause soil pollution

Dengue fever is an infectious disease caused by a virus and is transmitted by the Aedes aegypti mosquito. Dengue fever has not yet found a cure and the only prevention is through mosquito vector  control. Health Department policy to prevent and eradicate dengue fever today is to make eradication by means of mechanical, physical, chemical or biological. Biological is one of alternative  control of mosquito vectors that are safe for humans and the environment but still effective in suppressing the mosquito vector. One attempt to do that is by using animals to fight other creatures, or better known as biological control. In the present research was performed using fish of Betta spp, Cyprinus carpio and Oreochormis niloticus as a natural predator of the Aedes aegypti mosquito. The design of this research is  Completely Randomized Design (CRD) with three treatments are 3 types of fish with 5 times repeated. Data were analyzed with analysis of the range and tested further with the Smallest Real Differences Test (LSD) on the real level 5%. The result of this research is the ability Betta spp eating is higher than the Oreochromis niloticus and Cyprinus carpio by the number of larvae that consumed between 34.6 to 36.9 mosquito larvae tail. The ability to eat at various types of fish against mosquito larvae, influenced by several factors: the agressive, espesialisasi fish to food, the active duration and the amount of time the fish is active in 24 hours.
