Abstract

Background and Aim: IPB D1 chicken is a crossbreed developed by crossing local Indonesian chickens-Pelung, Sentul, and Kampung-with commercial broilers. This crossbreeding initiative led by researchers from the Faculty of Animal Science at IPB University, aims to develop a meat-type chicken breed that is well adapted to traditional backyard farming systems commonly found in rural areas.Materials and Methods: The objective of this study was to evaluate the resistance of IPB D1 chickens carrying the Toll-like receptor 4 (TLR4) gene against Salmonella enterica serovar Enteritidis. A total of 11 chickens were used in this experiment. Detection of the TLR4 gene was conducted using Polymerase Chain Reaction (PCR) and sequencing techniques, followed by assessment of the chickens' immune response through total and differential leukocyte counts.Results: The results showed that IPB D1 chickens with the TLR4-positive genotypes (GG and AG) exhibited stronger immune responses and more stable leukocyte profiles compared to TLR4-negative chickens (AA genotype) following exposure to S. Enteritidis. These findings suggest that the TLR4 gene plays an important role in innate immunity and may enhance resistance to bacterial infection.Conclusion: Overall, this study highlights the potential of IPB D1 chickens as a resilient local breed suited for sustainable poultry farming, particularly in resource limited environments.Keywords: IPB D1 chickens, leukocyte profile, non-specific immune response, Salmonella Enteritidis, TLR4 gene

Abstract

Haemorrhagic Septicaemia (HS) is a devastating disease affecting cattle and water buffaloes in Indonesia, causing annual economic losses in livestock industries, particularly in Asia, Africa, and the Middle East. Pasteurella multocida, the causative agent of the disease, has shown increasing antimicrobial resistance, complicating treatment efforts. Therefore, this study aims to provide the first genomic analysis of P. multocida isolates from different Indonesian provinces, focusing on genes conferring resistance to beta-lactam antibiotics based on Whole Genome Sequencing (WGS) results. Genomic data can be used to confirm the results of phenotypic antibiotic resistance testing. P. multocida isolates analyzed in this study were sourced from the Indonesian Research Center for Veterinary Science (IRCVS) collection, which included 2 samples originating from different geographic locations within Indonesia. The samples were subjected to biochemical, molecular, and antimicrobial susceptibility testing. WGS was performed using Oxford Nanopore Technologies (ONT) with subsequent bioinformatics analysis for genome assembly and resistance profiling. Phenotypic analysis showed significant variations between the isolates. The NTT isolate showed resistance to Penicillin, while the Lampung 2952 remained susceptible in the disk antibiotic test. Genome sequencing revealed extensive resistance determinants, including β-lactamase genes (blaZ, blaR1) in the NTT isolate, correlating with its phenotypic resistance. The high-quality genome assemblies (N50: 17,225 bp for NTT; 12,662 bp for Lampung 2952) enabled comprehensive resistome characterization, identifying more than 22 resistance genes in each isolate, including novel variants not previously reported in Indonesian strains. Therefore, this study provides the first genomic and resistance analysis based on Whole Genomic Sequencing data of Indonesian P. multocida isolates. The results show the urgent need for enhanced surveillance and prudent antimicrobial use in livestock management.
