Abstract

This research aimed to amplify a 1700 bp fragment of rpoB gene of multidrug resistance M. tuberculosis (MDR-TB) isolate and determine types of mutation beyond the core region (hot-spot region). DNA sequencing studies indicate that more than 95% of rifampin-resistant M. tuberculosis strains have mutations within the 81-bp hot-spot region (codons 507 to 533) of the RNA polymerase ?-subunit (rpoB). Since almost 90 % of rifampicin resistant isolate are also resistant to isoniazid, mutation in rpoB gene become important as a surrogate marker for MDR-TB. MDR- TB isolates used for this research, namely isolate 885, was collected by Regional Health Laboratory of Surabaya. PCR was used to amplify the gene, on described steps : a cycle of preheating at 95°C for 15 minutes, amplifying in 45 cycles ( 1 minute at 94°C, 1 minute at 58°C, 1 minute 72°C) and post extension for 5 minutes at 72°C. The mutations were detected by sequencing and alignment using MEGA4. The result of this research showed that there were new mutations downstream of the core region of rpoB. Sequence analysis showed some mutations such as S594A, S626V, T629A. In conclusion, it is reported for the first time, new mutations at downstream region of the core region of rpoB.

Abstract

Hypercholesterolemia or hyperlipidemia has been established as an important risk factor of cardiovascular disease. Patients with hypercholesterolemia usually require a prolonged treatment; and the newer and more potent generation of antilipid agents are costly.In Bali there are several types of seaweed that are generally consumed by the local people and known by the local names of Bulung Boni (Caulerpa spp.) and Bulung Sangu (Gracilaria spp.). Preliminary studies on the effect of Bulung Boni and Bulung Sangu extracts appeared to improve lipid profile, but the available data are still very limited both in extent and depth, and further investigations were considered relevant and needed.This experimental study used completely blind randomized design, using a total of 24 Wistar rats divided into six sample groups of equal size, all fed with a diet high in cholesterol content. The six sample groups were respectively designated as negative control group, positive control group, and four treated sample groups, respectively fed orally with a dose of 20 mg and 60 mg extracts of Bulung Boni per 100g of body weight per day, and 20 mg and 60 mg extracts of Bulung Sangu per 100g body weight per day. Each treatment was repeated four times.Our study showed that rats fed with high-cholesterol diet and treated with oral Bulung Boni or Bulung Sangu extract at a dose of 20 mg and 60 mg/100 g bw/ day were associated with statistically significantly increased plasma HDL levels (p < 0.05), and statistically significant decreased plasma LDL and total cholesterol levels (p < 0.05) as compared with those of rats fed with high cholesterol diet without treatment with Bulung Boni or Bulung Sangu extracts.From our data it could be implied that Bulung Boni and Bulung Sangu extracts improve lipid profile in the Wiatar rat by significantly increasing plasma HDL level, and lowering LDL and total cholesterol levels.

Abstract

Toxoplasmosis is a zoonotic disease caused by infection with the parasite called Toxoplasma gondii (T. gondii). The health and social impacts of the infectionare enormous, including miscarriage, hydrocephalus, blindness, and mental retardation. The occurrence of toxoplasmosis in maternal women cannot be se parated from cats around their houses. This study aimed to determine the seroprevalence of the parasite in cats found in the human carriers residences and identify the risk factors of toxoplasmosis in maternal women in Badung District, Bali Province, Indonesia. A total of 80 cat serum samples were obtained from two residential groups, 40 from the housing where the maternal women were infected and another 40 from where there were no identified sufferers of the disease. All the samples were examined using the enzyme-linked immunosorbent assay (ELISA) method to detect the presence of antibodies T. gondiiin feralcat serum. The results showed that 47.5% of the examined subjects had the said antibodies. As much as 65% came from housing with cases of toxoplasmosisin maternal mothers, and 30% came from residences with none. The presence of feral cats is a major risk factor for the transmission of T. gondiito humans.

Abstract

This study aimed to determine CD4 count from cryopreservation of Buffy coat (BC) and PeripheralBlood Mononuclear Cell (PBMC) with and without ficoll. Fifteen EDTA Blood sample (2 ml for eachtube) were drawn from one adult healthy subject. The samples were categorized into five group beforemeasuring the CD4 level (which were fresh whole blood [Group(G)-I], BC without ficoll [fresh <GII>and frozen <G-III>] , and PBMC resulted from BC and ficoll isolation [fresh <G-IV> andfrozen <G-V>]. Each group was replicated three times. Blood storage before preparation was less thanfour hours. Two months cryopreservation using liquid nitrogen (in 40% FBS, 10% DMSO, and RPMI)was conducted. The mean value of CD4 count (cell /mu1) were 522 (G-I), 1410 (G-II), 906 (G-III), 807(G-IV), and 733 (G-V). CD4 count, after 2 month preservation in liquid nitrogen, of the BC sample (G-III) was higher (906 cell /mu1) than PBMC (G-IV) sample (733 cell /mu1).

Abstract

Cryopreservation of PBMC (peripheral blood mononuclear cells) was done to preserve and analyze the number of PBMC derived from blood samples which come in at different time. The batch analysis wasperformed at the same time in order to reduce variations in results. The analysis on the cells numbers carried out after 1, 3, 6, 12, and 24 hours. Heparinized whole blood was collected from healthy subject by venipuncture, and stored at room temperature. Blood is processed by centrifugation in Ficoll density gradient following the established method of Balai Besar Veteriner Denpasar. Buffy coat layer was collected and washed twice with HBSS (Hank's balanced salt solution) and was counted in Turk’s solution. The cells were then dissolved in 1 ml of cold freezing medium containing 10% DMSO and 50% FBS (fetal bovine serum) and stored overnight at -80°C before storage in liquid nitrogen vessel for few weeks. The samples rapidly thawed in a water bath at 37°C and washed twice with PBS (phosphate buffered saline). The cells were stored in 4°C PBS and counted in Turk’s solution after 1, 3, 6, 12, and 24 hours. The results obtained were varied with a declining trend.

Abstract

Telah dilakukan penelitian untuk mengetahui daya sebar vaksin ND aktif galurlentogenik (La Sota) dan respons immune ayam yang tidak divaksin yang dipeliharabersama ayam yang divaksin secara intramuskuler. Penelitian ini menggunakan rancanganacak lengkap pola berjenjang (split time) dengan faktor utama perlakukan vaksinasi (TO:0% divaksin dan 100% tidak divaksin , T1: divaksin 50 % dan 50 tidak divaksin dan T2:divaksin 75% dan 25% tidak divaksin) dengan sembilan kali ulangan. Faktor tambahanadalah waktu pengambilan serum (minggu ke-0, ke-1, ke-2 dan ke-3) sehingga jumlahsampel adalah 3x9x4= 108 sampel serum. Ayam umur 3 hari divaksinasi ND secara tetesmata kemudian dilakukan vaksinasi intramuskuler pada umur 21 hari sesuai perlakuan.Titer antibodi ND pada ayam perlakuan diuji dengan uji hambatanhemaglutinasi/hemagglutination inhibition (HI) satu hari sebelum vaksinasi, serta satuminggu, dua minggu, dan tiga minggu setelah vaksinasi. Data tentang titer antibodi (GMTHI)terhadap ND ditransformasi dengan akar X+1, dianalisis dengan sidik ragam dandilanjutkan dengan uji jarak berganda Duncan. Hasil penelitian menunjukkan bahwa titerantibodi terhadap ND pada ayam yang tidak divaksin dipengaruhi oleh persentase ayamyang divaksin. Antibodi HI unit terhadap virus ND pada ayam yang tidak divaksinasimulai teramati pada minggu ke-2 dan ke-3 setelah vaksinasi. Titer antibodi ayam yangtidak divaksinasi pada kelompok ayam yang hanya divaksin 75% mempunyai titer antibodiyang nyata lebih tinggi dibandingkan dengan kelompok ayam yang divaksin 50% dankontrol (P<0,05). Pada kelompok ayam yang divaksin 50%, titer antibody ND pada ayamyang tidak divaksin secara statistik berbeda tidak nyata dibandingkan dengan kelompokyang divaksin 0% (P>0,05). Pada minggu ke tiga, titer antibody ND ayam yang tidakdivaksinasi pada kelompok ayam yang divaksin 75% nyata lebih tinggi dibandingkandengan pada kelompok ayam yang divaksin 50% (P,0,05).

Abstract

Ternak sapi yang menderita diare berpeluang besar untuk ditemukan adanya agen zoonosis E. coli O157:H7 mengingat sapi sebagai reservoir utama dari agen tersebut.Transmisi penularan strain bakteri ini ke manusia umumnya terjadi melalui konsumsi daging yang kurang dimasak, produk susu yang tidak dipasteurisasi, air yang terkontaminasi feses. Dusun Lampu sebagai salah satu Dusun di Desa Catur merupakan salah satu daerah potensial untuk pengembangan ternak khususnya sapi sehingga menjadikan program pelayanan kesehatan di wilayah tersebut sangat potensial untuk dilakukan. Hasil kegiatan pengabdian masyarakat berupa sosialisasi penyakit zoonosis E. coli O157:H7 serta pelayanan kesehatan ternak sapi di Dusun ini, memperlihatkan respon positif yang dicirikan dengan cukup banyaknya jumlah ternak yang memperoleh pelayanan yaitu sejumlah 65 ekor sapi dari 35 petani ternak. Jenis pelayanan yang dilakukan meliputi tindakan spraying atau pemberian butox terhadap semua ternak sapi yaitu 65 ekor (100%), disusul dengan pemberian vitamin pada 52 ekor (80%), pemberian obat cacing sebanyak 39 ekor (60%), serta pemberian delladryl pada 1 ekor sapi (1,5%). Hasil ini mengindikasikan bahwa program pengabdian yang dilakukan cukup efektif dapat menyentuh kebutuhan dasar petani ternak, sehingga benar-benar dapat dirasakan manfaatnya.
