Abstract

Haemorrhagic Septicaemia (HS), in Indonesia known as Ngorok disease is a fatal acute septicemia disease in cattle and buffalo caused by Pasteurella multocida. Outer membrane Protein H (OmpH) is one of the major proteins in P. multocida envelope has been purified and characterized as porin immunodominant. The aim of this study is to find out the homology of nucleotide sequence of 37 kDa OmpH gene of P. multocida of local isolate from NTT with vaccine strain (Katha) and 5 referen isolates and predict the epitope of 37 kDa OmpH gene. Detection of 37 kDa OmpH gene was done using PCR. Homology analysis of nucleotide and amino acid sequences was performed on the BLAST program at NCBI. Epitope prediction of 37 kDa OmpH genes P. multocida from NTT and vaccine strains was performed using the online programme B Cell Epitope Prediction Tools. The results showed that 37 kDa OmpH gene of P. multocida from NTT has 99% homology to vaccine strain (Katha) and isolates from China, Iran, India, Mesir, and 89% homology to isolate from USA and 37 kDa OmpH gene of P. multocida local isolate from NTT were likely to be immunogen candidates based on B cell epitope that had 11 epitopes. These findings indicate that P. multocida local isolate from NTT has a chance as immunogen candidate, which can be developed as a vaccine candidate and diagnostic kit for HS.

Abstract

This study were conducted to analyze the homology and the relation of nucleotidesencoding partial genomic sequence of Fusion (F) protein Newcastle Disease Virus (NDV) isolated from swanusing phylogenetic tree. Samples were collected from cloacal swabs of seventy one waterfowls. Consisting of twenty four Domestic swan, thirty three Muscovy ducks, and fourteen Domestic ducks form waterfowl in East Java Province, and also positive LaSota isolate (ATCC). Samples were isolated in embryonated chicken eggs(ECEs) with specific pathogen free (SPF)and identified by HA test and confirmed as NDV by HI test. Positive samples were performed by RT-PCR using a forward and reverse primer with a target of 699 bp.The nucleotide sequences from field isolates were compared with the gene of vaccine viruses isolates encoded F protein NDV that used in Indonesia and vaccine viruses encoded F protein NDV that spread across the globe obtained at GenBank data and had very close phylogenetic relation with those vaccine viruses LaSota.Analysis of homology and phylogenetic from isolates in this study relate to isolate of vaccine viruses.
