Abstract

Kasus penyakit Infectious Bursal Disease (IBD) dewasa ini masih sering ditemukan pada peternakan ayam komersial baik layer maupun broiler di Indonesia. Diagnosis penyakit IBD sejauh ini mengandalkan lesi patologik spesifik dan kultur in ovo dengan mengamati lesi makroskopis embrio, serta diidentifikasi dengan uji agar gel presipitasi (AGP). Penelitian ini bertujuan menerapkan diagnosis dengan teknik reverse transcriptase polymerase chain reaction (RT-PCR) dari sampel Bursa Fabrisius (BF) sebagai konfirmasi pada kasus terdiagnosa IBD. Deteksi serologis virus IBD dengan uji AGP dengan sumber antigen chorioallantoic membrane (CAM) dan embrionya, untuk melihat potensinya sebagai sumber antigen uji AGP. Sampel BursaFabrisius sebanyak 5 yang diperoleh pada kasus terdiagnosa IBD, dikoleksi dari peternakan ayam komersial di Yogyakarta. Konfirmasi diagnosis dilakukan dengan metode RT-PCR. Sampel positip uji RT-PCR yang mengamplifikasi fragmen gen VP2. Isolasi virus IBD yang dilakukan kultur in ovo pada telur ayam berembrio (TAB) antibodi negatif terhadap virus IBD, berumur 11 hari. Desposisi materi inokulasi dilakukan pada (CAM), diinkubasi selama lima hari. Panen virus dilakukan dengan mengkoleksi membran korioalantois dan embrio, selanjutnya diamati lesi makroskopis yang timbul akibat infeksi virus IBD. Membran korioalantois dan embrioselanjutnya digerus dan diproses sebagai suspensi antigen yang digunakan dalam uji AGP. Hasil uji RT-PCR terhadap lima sampel Bursa Fabrisius yang dikoleksi dari peternakan ayam terdiagnosa penyakit IBD, tiga sampel menunjukkan hasil positif teramplifikasi fragmen gen VP-2 virus IBD dengan produk amplifikasi sebesar 440 bp, sedangkan dua sampel sisanya menunjukkan hasil negatif. Uji AGP dengan sumber antigen CAM menunjukkan hasil positip 2 dari 3 sampel yang diuji, sedangkan sumber antigen embrio menunjukkanhasil negatif. Berdasarkan data yang diperoleh dalam penelitian ini dapat disimpulkan bahwa uji RT-PCR dapat digunakan dalam mendeteksi virus IBD dari sampel BF terdiagnosa IBD. Uji AGP dengan sumber antigen CAM menunjukkan hasil lebih baik dari pada embrionya.

Abstract

Controlling SepticemiaEpizooticae (SE) through vaccination program has been undertaken in KupangDistrict. However, numbers of fatal cases is still being reported. A cross sectional study have been undertakenin order to determine the prevalence and factors affecting herd immunity at farm level in Kupang District.A total of 434 cow?s sera from 87 farmers were collected and further analyzed using Enzyme-linkedImmunosorbent Assay (ELISA). An antibody titer of e?200 ELISA Unit was used as the indicator ofprotective immunity. The prevalence of herd immunity was 73.7% and vaccination coverage was 90.8%.Based on unweighted logistic regression analysis it was found that factors affecting the animals protectiveimmunity were: animal >2 years of age (r = +1.45601; OR = 4.3); housing system ( r = +1.03958; OR = 2.8);reservoir animals (r = +0.090147; OR = 2.5), the sex of the animal (female) (r = + 0.080138; OR =2.2); oncefrequency of vaccination (r = +0.61015; OR = 1.8); and 6-12 months post vaccination period (r = + 0.58968;OR = 1.8). Based on linier regression analysis, the prevalence of herd immunity was increased during rainyseason, whereas it was decreased when cows werebought from animal market or from other district.

Abstract

Infectious coryza (snot) is one of acute respiratory disease in breeders, layers, and broilers caused by Avibacterium paragallinarum (Av. paragallinarum). This disease is very harmful because of its cause decrease in egg production and high morbidity. Snot incident in Indonesia still is reported. Vaccination is one of the best preventive measures, but reports about Av. paragallinarum serotype at the field so lack so that the correspondence between serotype Av. paragallinarum in the field to those used for vaccination is unknown. Av. paragallinarum has strains with different antigenicity and until now known three serotypes there are serotypes A, B and C. Serotypes A and C are pathogenic then serotypes B. The purpose of this study was to isolate, identify and to determine the serotype of Av. paragallinarum from the commercial layer that showing symptoms of snot. Samples were taken from layer which showed symptoms of snot (nasal foul smelling exudate, infra-orbital and wattle swelling, conjunctivitis, and snoring) from some layer farms. Samples were cultured on chocolate agar and then incubated in a candle jar at 37 ?C for 18-24 hours. Bacteria colony and cell morphology were observed and performed biochemical tests (catalase, oxidase, urease, indole, and fermentation of carbohydrates) in suspected colonies. Serotypes test was conducted using plate agglutination test (PAT). This study revealed 4 isolates Av. paragallinarum with 2 isolates are serotype B and 2 other are serotype C.

Abstract

Infectious coryza (IC) is an acute upper respiratory disease of poultry that can appear in all ages. Some of clinical signs that are commonly seen in IC are rhinitis, facial swelling or edema, lacrimation, anorexia, and retarded growth in young poultry [1.2.3]. The disease can be found worldwide, especially in tropical countries [4]. Infectious coryza is very important in the chicken farm industry in developed and developing countries, including Indonesia [5]. The large economic losses due to IC such as increased number of culling, decreased egg production (10-40%), decreased body weight, stunting growth, and some mortality (2-10%) [4].Avibacterium paragallinarum which was previously classified as Haemophilus paragallinarum is a causative agent of infectious coryza in laying and broiler chickens, quail, pearl chicken, turkey, and peacocks [4,6,7,8]. The bacteria is commensal in the mucous membrane of the upper respiratory system, is sensitive to preservation and does not last long outside the host body [8]. Factors X and V are needed for the growth of several types of A. paragallinarum. According to in vitro growth requirements, A. paragallinarum can be either nicotinamide adenine dinucleotide (NAD) independent or NAD-dependent. The reduced form of NAD (NADH; 1.56-25 µg/ml) and the oxidized form (20-100 µg/ml) is required for in vitro growth in most isolates A. paragallinarum that show satellitic colony on a medium [9]. The description of the need for V factor of field isolates A. paragalinarum has been few reported. The aim of this research is to find out the phenomenon of satellite colonies from a variety of poultry isolates.

Abstract

The aim of the study was to determine sequence and genotype diversity of protective antigenic gene ofBacillus anthracis isolated from Central Java and Yogyakarta. Pag-A gene which encodes for antigenicprotein is one toxin component and the virulent factor of B. anthracis. As many as five isolates fromSemarang, Sragen, and Boyolali (Central Java) and Sleman (Yogyakarta) were used. The gene wassequenced and amplified used three set of primers PA1857/PA2436, PA8/PA5, and PA-5F/PA-5R. Theresult showed that the nucleotide sequences of gene from five isolates were identical and only had onenucleotide difference as compared to B. anthracis sterne M22589. All isolates were confirmed as genotypebased on pag-A sequence. It was concluded that all B. anthracis from Central Java and Yogyakarta haveidentical pag-A sequence and belong to genotypt-1. Further studies are needed to investigate B. anthracisisolates from other regions of Indonesia.

Abstract

Avibacterium paragallinarum is the aetiology of Infectious coryza (snot), one of acute upper respiratory tract diseases, which causes financial loss due to the decrease of egg production in layer. This is Gram negative bacteria which have three serotypes, known as serotype A, B, and C. The aim of this research was to know the sensitivity of Avibacterium paragallinarum to different kinds of antibiotics that are commonly used. This research used Avibacterium paragallinarum culture derived from layer which showed the symptoms of snot. Sensitivity test applied erythromycin, enrofloxacin, gentamycin, amoxicillin and clavulanic acid, and sulfamethoxazol. Results found the sensitivity of Avibacterium paragallinarum to combination of amoxicillin and clavulanic acid was 100%, to erythromycin 50% resistant and 50% intermediate, to enrofloxacin 75% resistant and 25% intermediate, to gentamycin 75% sensitive and 25% resistant, and to sulfamethoxazol 100% resistant.
