Synopsis
Antibiotic resistance is a growing global health crisis, rendering many life-saving drugs ineffective and complicating the treatment of bacterial infections. Predicting antibiotic resistance in bacterial strains based on genomic or metagenomic data can help guide clinical decisions, improve treatment outcomes, and inform public health strategies. In this project, we aim to develop a deep learning-based system to predict antibiotic resistance by analyzing bacterial genomes. The model will use sequence-based approaches, such as Convolutional Neural Networks (CNNs) or transformer architectures, to identify mutations, genes, or pathways associated with resistance. Additionally, multi-task learning will be employed to predict resistance to multiple antibiotics simultaneously, enabling a comprehensive analysis of bacterial strains. This approach will assist in early identification of resistant strains, optimize antibiotic stewardship, and accelerate drug discovery.
Relevance of the Topic
The rise of antibiotic-resistant bacteria poses a significant threat to global health, food security, and economic development. Traditional methods for detecting antibiotic resistance, such as culture-based assays, are time-consuming and labor-intensive. Automated prediction systems using genomic data can provide rapid and accurate insights into resistance profiles, enabling timely interventions. With the increasing availability of genomic datasets and advancements in deep learning, there is an opportunity to develop scalable models that can address this critical challenge.
