Abstract

Avian influenza (AI) merupakan penyakit infeksius disebabkan oleh virus influenza tipe A dari famili Orthomyxoviridae (Boyce et al., 2009) yang berpotensi menyebabkan kerugian bagi dunia perunggasan di seluruh dunia termasuk Indonesia. Virus AI memiliki 8 segmen gen yang berbeda yang mengkode 10 jenis protein virus yang berbeda. Struktur protein dalam virion dewasa dapat dibagi menjadi protein permukaan dan protein internal. Termasuk ke dalam protein permukaan adalah hemaglutinin (HA), neuraminidase (NA), dan membran kanal ion (M2), sedangkan protein-protein internal meliputi nukleoprotein (NP), protein matriks (M1), dan kompleks polimerase yang tersusun dari polimerase basa 1 (PB1), polimerase basa 2 (PB2), dan polimerase asam (PA). Dua protein tambahan lainnya adalah protein nonstruktural 1 (NS1) dan nonstruktural 2 (NS2) (Lee dan Saif, 2009).Virus influenza A dikelompokkan berdasarkan dua antigen permukaan virus, yaitu protein hemaglutinin (HA) dan protein neuraminidase (NA), yang sampai saat ini telah ditemukan 18 HA (H1-H18) dan 11 NA (N1-N11)  (Tong et al., 2013; Heider, 2015). Hemaglutinin (HA) memiliki fungsi utama untuk menginisiasi infeksi, berinteraksi dengan reseptor asam sialat sel hospes (Edinger et al., 2014) serta menentukan patogenisitas virus AI H5N1 (Li et al., 2011).Wabah highly pathogenic avian influenza (HPAI) subtipe H5N1 pertama kali dilaporkan pada unggas di Indonesia pada tahun 2003. Kejadian wabah penyakit antara periode 2003-2004, virus-virus H5N1 di Indonesia masih merupakan clade 2.1. Dua tahun kemudian setelah kejadian wabah pertama, clade 2.1 berkembang menjadi tiga sublineage virus, yaitu clade 2.1.1, 2.1.2 dan 2.1.3 (Anonim, 2008). Sub-clade 2.1.2 terdiri dari virus-virus yang menginfeksi unggas dan manusia. Sub-clade 2.1.3 berhasil diisolasi dan diidentifikasi dari kasus fatal pertama H5N1 di manusia di Indonesia pada tahun 2005 (Parry, 2005). Sejak tahun 2008, virus-virus clade 2.1.1 dan 2.1.2 tidak lagi dijumpai baik pada unggas dan manusia, sedangkan virus-virus dari clade 2.1.3 terus berkembang menjadi tiga kelompok virus baru, hasil evolusi dari sub-clade 2.1.3 membentuk sub-clade baru yang masih termasuk dalam sub clade 2.1.3 (Takano et al., 2009) yaitu sub-sub-clade 2.1.3.1,  2.1.3.2  dan  2.1.3.3 (Wibawa et al., 2014). Tujuan dari penelitian ini adalah melakukan analisis clade dan patotipe pada virus AI clade 2.3.2.1c yang bersirkulasi di Lampung pada tahun 2016-2017.

Abstract

The objective of this research was to study the impact of high phosphor diet on the femur of ratsconsuming soybean. Ten female rats at 4 weeks of age were randomly divided into two groups of five, NP(rats fed with normal phosphor diet) and HP (rat fed with high phosphor diet). Each rats was placed intoindividual cages at 22-25°C. All  rats were given normal diet and water which were  provided ad libitum.The rats were also adaptation for three weeks before the treatment was given.  At seven weeks of age, ratsin NP group were fed normal diet (calcium:phosphor=0,6%:0,4%), while rats in HP group were fed highphosphorus diet (calcium:phosphor=0,6%:3,6%) for 6 weeks. At the end of the study, blood was collectedfrom plexus retroorbitalis for calcium and phosphor analysis, while right femur was taken forhistopathological examination using hematoxylin and eosin stain. The research results showed that bloodof calcium was significantly reduced (P<0.01) in HP group compared with NP group, while blood phosphorwas significantly increased (P<0.01) in HP group. Histopathological analysis of the proximalis femur inNP group showed the osteogenic zone of physis and the trabecular bone speculum of metaphysis werenormal, while the osteogenic zone of physis and the trabecular bone speculum of metaphysis in HP groupwere irregular.  Fibroblast in  trabecular bone speculum of bone marrow were also observed.  It can beconcluded that high phosphorus diet may cause osteodystrophia fibrosa in rats.

Abstract

Bovine viral diarrhea virus (BVDV) is a common pathogen that causes major economic losses to dairyindustry worldwide. Amplification of 5’-UTR regions of BVDV genome from blood samples usingreversetranscriptase polymerase chain reaction (RT-PCR) is one of sensitive and accurate techniques forBVDV detection. A common limitation for molecular detection of virus is the ability to obtain high qualityof nucleic acid in the samples. Inappropriate storage conditions will result in a false negative test. FiveEDTA-blood samples collected from BVDV persistently infected cattle were used in the present study.Ten repetitions were done for each sample. The blood were then dripped in the middle part of the FlindersTechnology AssociatesTM (FTA) cards and let it dried for approximately 2 hours. The effectiveness of theFTATMcards for storage and retrieval of BVDV RNA from blood samples molecularly using RT-PCRtechnique were tested and evaluated. The results proved that FTATM cards are effective and safe for thestorage of BVDV genome for a long period at room temperature. Based on the result of the present study,it can be concluded that in veterinary medicine field, the application of FTATM technology needs to bedeveloped to various type of samples and should be used routinely for collecting samples containinginfectious agents.
