Abstract

Escherichia coli O157:H7 has been identified as one of the most devastating microorganism causing diseases in human. The infection by this bacteria causes a wide spectrum of clinical manifestations ranging from asymptomatic, diarrhea or bloody diarrhea, up to serious clinical conditions such as hemorrhagic colitis, and hemolytic uremic syndrome. Poultry is known as one of its reservoir besides cattle and pig. Moreover, the use of antibiotic in animal feed as growth promoters is common worldwide. Due to its potential threat to public health, sensitivity test against various antibiotics and studying the plasmid DNA profiles are necessary. The study was initiated by cultivation of isolates, followed by test of antimicrobial susceptibility against various antibiotics and then by analyzing the plasmid DNA profiles. Results of study showed that among of 7 E. coli O157:H7 local isolates originated from chicken feces, as many as 42.9%; 14.3%; 14.3%; and 14.3% were resistant to 2; 3; 4; and 5 various of antibiotics, respectively. Base on the type of antibiotic, 85.7%; 71.4%; and 42.9% showed resistance to Methicillin, Penicillin G, Doxycycline and Streptomycin. Plasmid DNA of each isolates showed characters variation too, ranging from 2 to 4 bands with molecular weight ranging from 19.457 bp; 15.137 bp, 5.749 bp, 4.118 bp, 3.500 bp, 2.957 bp and 2.024 bp. Results of study indicated that local isolates of E. coli O157:H7 isolated from chicken showed multiple antibiotic resistance against various antibiotics, as well as its plasmid DNA profiles.

Abstract

Biosecurity is an effort to protect livestock and reduce the risk of spreading diseases that have a negative impact on livestock. This study aims to measure the attitude of the public towards the application of biosecurity. We surveyed 100 tourists who visited Sato Loka, which is an animal-based tourist object, using a questionnaire that has been tested for validity and reliability. The data were analyzed using descriptive analysis and scoring. The results show that the travelers' attitudes for the cognitive, affective, and conative indicators were 92.9%, 92%, and 91%, respectively. These indicators are interrelated; cognitive indicators are related to knowledge, which is closely related to changes in one's attitude. The majority of tourists who visit are young tourists (17-25 years old). Young tourists have good cognitive abilities because they are able to absorb various information quickly so that it will influence their actions towards something. The study concludes that most tourists who visit Sato Loka have a very positive attitude towards the application of biosecurity, but there is still an attitude that needs to be enhanced further regarding the use of special footwear when entering the wildlife area in order to create a safe and comfortable tourist attraction, both for tourists and animal.

Abstract

This study aims to identify and characterize receptor binding sites (RBS) and antigenic sites (HVR-I and II) of the S1 gene fragment of the infectious bronchitis virus (IBV) isolated and propagated from commercial chickens in Java Region to monitor recent circulating virus. The samples in this study were the organs which indicated infectious bronchitis infection. The stages of this research consisted of making virus suspensions, isolation, and propagation, as well as molecular detection and characterization of viruses. Virus isolation and propagation were carried out on chicken embryonated eggs aged 11 days via the allantoic route. Culture confirmation was performed by RT-PCR of the S1 gene fragment, followed by sequencing and bioinformatics analysis. The 168-hour propagation was observed in both dwarfed and curled embryos of two isolates from 11 isolates detected as IBV-positive. Phylogenetic tree construction resulted in all isolates being grouped as GI-19 genotype (QX-like). Amino acid identity among QX-like strains was calculated at 87–100%. A total of 210 predicted amino acid residues were observed, including 31 substitutions and 2 deletions. Conclusions of this study were identified and characterized as GI-19 genotype (QX-like) IBV with amino acid changes on S1 fragment from breeder, broiler, and layer chickens in Java Region.

Abstract

Infectious Bursal Disease (IBD) is an infectious and immunosuppressive disease primarily affecting young chickens. Despite stringent biosecurity and vaccination for control measures, the effective management of IBD remains challenging. The disparity in observed clinical symptoms in the field infections further complicates matters for breeders. The study aims to perform molecular characterization of VP2 gene fragments to identify the latest genotype of field IBD viruses. Twenty-two samples of bursa of Fabricius were collected from broilers suspected of IBD in commercial farms located in Central Java and The Yogyakarta Special Region from 2021 to 2022. Viral RNA was extracted from these samples, and after amplification, a 743 bp PCR product was obtained and subjected to sequencing. The obtained sequences were analyzed in Mega X for multiple alignments, amino acid prediction, homology, and phylogenetic tree construction. Lesion, i.e., Bursa of Fabricius enlargement, oedema, swelling of plica bursa, gelatinous mass, hemorrhage, atrophy, and thigh muscles petechiae to hemorrhage, were considered indicative of IBD. Out of 22 samples tested by RT-PCR, 19 were positive, and 13 samples were selected for sequencing. All sequenced samples belonged to Genogroup A3, specifically the very virulent IBD (vvIBD) strain.

Abstract

Clinical symptoms in the chicken’s respiratory system, such as sores, nasal discharge, gasping, and so on, can be caused by a variety of possible socks. These signs may be caused by a virus, usually followed by economic losses. Causative diagnosis, especially virus detection, is needed to establish the cause of the symptoms. The study aims to detect Newcastle Disease (ND), Avian Influenza (AI), and Infectious Bronchitis (IB) cases of respiratory symptoms in commercial chickens by 2023. The samples studied in this study were organs from commercial chicken broilers and layers with respiratory symptoms. The organ was prepared as a suspension, then centrifuged to take out the supernatants. Supernatants were extracted using commercial extraction kits to produce templates for molecular detection. Molecular detection was performed using the RT-PCR two-step method. Primer pairs were used for the detection of ND, AI subtypes H5 and H9, as well as IB. The results were visualized by electrophoresis with 1.5% agarose. Interpretation of the positive result of RT-PCR based on the appearance and length of amplicons compared with the positive control of each virus. Positive RT-PCR samples with thick amplicon quality were subjected to sequencing and bioinformatics analysis. Results of detection with RT-PCR against 41 samples are positive ND of 1 out of 8 samples (12.5%), AI of 2 out of 17 samples (11.7%), and IB of 5 out of 16 samples (31.3%). Based on the molecular detection with RT-PCR, the symptoms of respiration in commercial chickens are confirmed due to the cause, namely the virus: ND genotype VII-i, AI subtype H5 clade 2.3.2, AI subtype H9, and IB genotype GI-19 (QX-like).

Abstract

Penelitian ini bertujuan mengevaluasi status virulensi 22 isolat Bacillus anthracis (B. anthracis) asal Nusa Tenggara dan Papua menggunakan metode polymerase chain reaction (PCR) multiplex dengan dua pasang primer nukleotida yang memiliki target amplifikasi gen spesifik pada kedua plasmid. Ektraksi DNA dilakukan dengan metode lisis panas. Pasangan primer PA5 dan PA8 digunakan untuk mengamplifikasi gen pagA pada pXO1, sedangkan pasangan primer 1234 F dan 1301 R mengamplifikasi gen capABC pada pXO2. Hasil reaksi PCR menghasilkan dua pita DNA berukuran sekitar 600 dan 800 bp pada 20 isolat. Namun, dua isolat lain, masing-masing hanya memiliki salah satu dari kedua ukuran pita DNA tersebut. Sebagian besar koleksi isolat asal Nusa Tenggara dan Papua (91%) masih memiliki kedua plasmid secara lengkap (pXO1+/2+) dan karena itu bersifat virulen, sedangkan dua isolat lain (9%) telah kehilangan salah satu plasmid virulennya sehingga bersifat avirulen. Disimpulkan bahwa PCR multiplex dengan dua pasang primer dengan target amplifikasi pada plasmid dapat digunakan untuk evaluasi status virulensi isolat B. anthraci.
