Epidemiological studies of zoonotic agent Escherichia coli O157:H7 have been analyzed pheneticallyand or phylogenetically. In a phenetic classification, micoorganisms are arranged into groups (phena) onthe basis of high overall similarity using both phenotypic and genotypic methods without judgementaspect of its ancestry or evolutionary. Due to its importance to epidemiological aspect, the study of geneticvariation of isolates origin from some sources need to be conducted in order to trace the routes of infection.A total of 20 samples obtained from some sources i.e clinically human feces, non-clinically human feces,cattle feces, chicken feces, and beef feces were used in this study. The study was started by confirming allof the isolates using O157 latex agglutination test and H7 antiserum test, followed by genomic DNAanalysis by random amplification of polymorphic DNA /RAPD methods. RAPD results were analyzedÂ using a simple matching coeficient (Ssm) and alogorhythm unweighted pair group method using arithmeticaverages (UPGMA) programe. Results showed there were range of genetic DNA from local isolates (75.1â€“99,6%) which was almost similar to ATCC 43894 control isolate. The highest similarity (99.6%) to ATCC43894 control was showed by SM-7(1) isolate obtained from cattle fecal and KL-68(1), isolate obtainedfrom clinically human fecal. In addition, KL-52(7) obtained from clinically human fecal had high similarity(99.6%) to MK-35 isolate obtained from chicken fecal. On the other hand, DS-21(4) and DS-16(2) isolatesthat were obtained from beef had high similarity (84.9%) to other isolates including ATCC 43894 controlisolate. The highest similarity of E. coli O157:H7 isolates that were obtained from cattle feces, beef, andchicken feces to human feces isolate indicated that there were both cattle and chicken were potentialreservoirs of the zoonotic agen which can be transmitted to human.

Wabah avian influenza (AI) di Indonesia telah terjadi sejak akhir tahun 2003 dan masih terjadi secara endemis sampai sekarang. Pada akhir tahun 2012 terjadi kasus kematian yang cukup tinggi pada itik yang disebabkan penyakit AI subtipe H5N1 yang diklasifikasikan ke dalam clade 2.3.2, sedangkan virus AI sebelumnya diklasifikasikan pada clade 2.1.1, 2.1.2 dan 2.1.3. Salah satu yang berperan dalam virulensi penyakit AI adalah motif asam amino C-terminal protein nonstruktural1 (NS1). Analisis sekuens virus influenza terutama protein nonstruktural 1 (NS1) yang berasal dari unggas mempunyai motif asam amino ESEV pada Cterminal sedang pada virus influenza manusia mempunyai motif RSKV pada C-terminal. Data sekuen NS1 untuk virus AI terbaru belum lengkap sehingga perlu disekuen untuk melengkapi data molekuler NS1 virus AI.Residu C-terminal protein NS1 virus avian influenza subtype H5N1 perlu dikaji karena mempengaruhi patogenisitas dan virulensi virus. Penelitian ini bertujuan untuk mengetahui motif asam amino pada C-terminal protein nonstruktural 1 (NS1) virus avian influenza yang menyerang itik pada tahun 2013. Sampel berasal dari kasus AI pada itik di Tulungagung dan Blitar pada tahun 2013. Isolasi virus menggunakan telur berembrio tertunas ayam. Identifikasi virus AI subtipe H5N1 menggunakan teknik reverse transcription polimerase chain reaction (RT-PCR) dengan primer H5 (Lee et al., 2001) dengan target amplifikasi 545 bp dan primer N1 (Payungporn et al., 2004) dengan target amplifikasi 131 bp. Amplifikasi gen NS1 menggunakan RT-PCR dengan 2 pasang primer (Bannet-Noah et al., 2007) yang didesain mengamplifikasi gen NS dan dilanjutkan proses sekuensing gen NS1. Sekuen yang diperoleh dianalisa dengan menggunakan software MEGA 5.05 yang meliputi multiple alignment, prediksi asam amino dan analisis pohon filogenetik. Hasil sekuen isolat diperoleh panjang nukleotida yang mengkode protein NS1 sepanjang 690 nt. Hasil analisis pohon filogenetik menunjukkan bahwa ke lima isolat uji tidak berada satu grup dengan dengan isolat asal Indonesia tahun 2003- 2008 dan berdekatan dengan klaster virus AI yang berasal dari Asia clade 2.3.2. Pada semua isolat tahun 2013 ditemukan delesi asam amino pada posisi 80-84, substitusi asam amino D92E, asam amino 149 semua isolat mempunyai asam amino alanine (A), asam amino ke 196 ditemukan adanya variasi substitusi berupa lysine (K) dan glutamic acid (E) dan asam amino pada gen NS1 mempunyai motif ESEV pada posisi PDZ ligand.

The information on pathogenicity and adaptation factors of avian influenza virus (AIV) in mammalsis very inportant in an effort to reduce the risk of avian influenza (AI) pandemic in the future. Polymerasegene complex appears to be the major factors for adaptation of AIV to certain animal species. A preliminarystudy on role of non-coding region (NCR) and amino-terminus of polymerase-basic 2 (PB2) is presented.Purified viral RNA of AIV isolated from chicken, duck, pig, and quail of Bali and Yogyakarta was reversetranscribed into cDNA and amplified using reverse transcriptase-polymerase chain reaction (RT-PCR)using PB-2 universal forward primer and specifically designed backward primer. The result showed thatall AIVâ€™s H5N1 isolated from chicken, duck, quail, and pig, posed PB2 amino-terminus typical for IndonesianAIV H5N1. However, polymorphic amino acids of the protein fragment did not show any species specificmotive, with the exception of the pig isolate Sw/Tabanan/2006 which had specific substitution of D16E,H17Q, M40I, and H124Y.

Green tea is an aqueous infusion of dried unfermented leaves of Camellia sinensis. Numerous biological activities of green tea have been reported. The aqueous infusion and its polyphenolic substance are known for their activity as an antimutagenic,Â antibacterial, hypocholesterolemic, antioxidant, and mutagenic of B lymphocyte. Studies have demonstrated that green tea polyphenols increase IL-12 production. Salmonella spp infection is an important public health problem in many countries. Cell-mediated immunity (CMI), especially T-cell help is important for protection against this infection. Recent evidence indicates that IL-12 is one such factor that plays a crucial role in the development of CMI. These studies were carired out to investigate the effect of green tea polyphenols to the immune cellulare in mice responses of mice during Salmonella typhimurium infection. The subject consisted of 36 female mice (Balb/C), 6-8 weeks old, divided into 3 groups. The first group was given 10 mg polyphenols/mouse, the second group was given 5 mg polyphenols/mouse, and the third group as the control. In day 31, all mice were infected with 108 CFU Salmonella typhimurium orally. On day 0, 3, 5, and 7 postinfection, 3 mice from each groups were sacrificed, the splenocytes were extracted and cultured to measureÂ the level of IFN-g in the supernatan and. The peritoneal macrophages were also extracted and cultured to measure the phagocytic activity. The level of IFN-g in splenocyte culture supernatantÂ increased during infectionÂ in all groups, but the level of the experimental groupsÂ were higher than in control group. TheÂ percentage of phagocytic activity of peritoneal macrophages were higher in the experimental groups than in the control group. The increase of the phagocytic activities were seen corelate with the level of IFN-g supernatan splenocyte culture.

Chrysomya bezziana is a fly causing myiasis in most livestock in Indonesia. To date, the genetic diversity of C. bezziana has been argued among researchers. The aim of this study was to analyse genetic diversity of C. bezziana population in Indonesia using mitochondrial cytochrome b gene (cyt b) as a marker. The preliminary study showed that the larvae instar III stadium (L3) was the most appropriate sample for molecular analysis and identification. Twenty-four L3 were collected from cattles, buffalos and horses in Bogor, Makassar and East Sumba. DNA samples were isolated from muscle tissue of the larvae. The fragment of cyt b gene (279 bp) was amplified using primer CB3FC-NINFA. The PCR product was subsequently purified, sequenced and analysed using PAUP version 4. The results showed that C. bezziana from Indonesia was different with those from Asia, basicaly for DNA sequences, however it had similar to those from Papua New Guinea. Two haplotypes were identified i.e. haplotype 6 (Makassar haplotype that similar to those from Papua New Guinea) and haplotype 7 (Bogor haplotype that similar to those from Makassar and East Sumba). Key words: Chrysomya bezziana, genetic diversity, mitochondrial DNA

Resistance to benzimidazole at a population of gastrointestinal nematode, especially Haemonchus contortus is a widespread problem. Therefore, anthelmintic will not effective anymore. Benzimidazole resistance in nematode has been shown to be heritable and defined as an increase in frequency of individual worms able to drug tolerate. In Indonesia resistance to anthelmintic albendazole has been reported on sheep in district of Bogor, Kuningan, Kendal and province of Yogyakarta. Molecular mechanism of resistance to benzimidazole on nematode and fungi related to single gene which code Ã tubulin. The aim of this research is to determine a genetics variability of isotype-1 Ã tubulin genes from Indonesian strain of H. contortus which resistant to benzimidazole. Sequencing were carried out at a 520 bp fragment of the isotipe-1 Ã tubulin gene of six H. contortus resistant strain from four sheep from SPTD Trijaya farm, district of Kuningan, West Java; UPTD Pelayanan Kesehatan Hewan farm, district of Bantul, Yogyakarta respectively. One H. contortus susceptible strains as a control come from farmer from Cicurug, district of Sukabumi, West Java. Results indicated that there are genetics variability ofÂ fragment isotype-1 Ã tubulin genes from H. contortus from UPTD Pelayanan Kesehatan Hewan farm, Bantul, Yogyakarta (H1, H2, and C2). There are no genetics variability in the fragment gene of H. contortus resistant strain from SPTD Trijaya farm, Kuningan, West Java (Kn1, Kn2 and K1). Genetic variability occur between 2 isolate from different location. Key Words: Haemonchus contortus, Benzimidazole, Isotype 1 Î²-tubulin Gene, Sequencing
