inhibition of avian pox virus replication by mangosteen rind and red ginger ethanolic extracts.

Background And Aim: Avian pox is a contagious disease caused by the avian pox virus (APV). Mangostin and γ-mangostin in mangosteen rind (MR) and gingerol in red ginger (RG) exhibit antiviral activity. In this study, we evaluated the effect of MR and RG ethanolic extracts on APV based on pock lesions on the chorioallantoic membrane (CAM) of specific pathogen-free (SPF) embryonated chicken eggs (ECEs).

Development of a coagglutination kit as a rapid test for diagnosing Newcastle disease in poultry.

Background And Aim: Newcastle disease (ND) is a viral infection that causes high mortality and economic loss in the poultry industry. The Office International des Epizooties (OIE) recommends several diagnostic methods for the detection of ND, including isolation and molecular tests. However, these detection methods are time-consuming and highly expensive.

Lab-Made Electronic Nose for Fast Detection of and .

The aim of this study is to determine the performance of a lab-made electronic nose (e-nose) composed of an array of metal oxide semiconductor (MOS) gas sensors in the detection and differentiation of () and () incubated in trypticsoy broth (TSB) media. Conventionally, the detection of and is often performed by enzyme link immunosorbent assay (ELISA) and polymerase chain reaction (PCR). These techniques require trained operators and expert, expensive reagents and specific containment.

Effect of mangosteen (.) peel extract as an antibiotic growth promoter on growth performance and antibiotic resistance in broilers.

Background And Aim: Antibiotic resistance poses a risk to human health and has therefore been the focus of research. One of the causes of this resistance is the use of antibiotics as feed additives for animal nutrition. The development of antibiotic resistance in poultry through nutrition feed has drawn attention to the need for alternative antibiotic growth promoters (AGPs).

Cloning and sequencing , , and genes to perform the genetic variability of bovine herpesvirus-1 from Indonesia.

Aim: Previous research has shown that bovine herpesvirus-1 (BHV-1) in Indonesia was closely related to subtype-1 based on genes. This study aimed to analyze the genetic variability of the BHV-1 isolated from the recent case in Indonesia not only based on but also other genes such as and and to study the homology and similarity of the sample to other BHV-1 isolated in other countries or regions.

Materials And Methods: Samples were drawn from the tracheal organ in recent field case and prepared for DNA extraction.

Use of M2e ELISAs for longitudinal surveillance of commercial poultry in Indonesia vaccinated against highly pathogenic avian influenza.

In countries where highly pathogenic avian influenza virus (HPAIV) H5N1 is endemic and controlled by vaccination, post-vaccination serological monitoring is essential to differentiate vaccinated poultry from those that are infected. The objectives of this study were to validate two experimental ELISAs that detect antibodies raised against the M2e protein of avian influenza virus that can be used for DIVA purposes. Results from the sM2e and tM2e ELISAs were compared with other conventional tests for the detection of H5N1influenza virus (virus isolation and RT-PCR) using samples collected from 16 commercial flocks in Indonesia.
