Kevin and Andrew discuss major bioinformatics conferences coming up in 2024, including:

ABPHM (Applied Bioinformatics and Public Health Microbiology) - Held every 2 years in the UK, next one likely in 2025. Smaller size (~150 people), very applied and focused on implementation.

ASM NGS (ASM Next Generation Sequencing Conference) - US equivalent of ABPHM, also applied and implementation focused. Next one is in October 2024.

PHA4GE (Public Health Alliance for Genomic Epidemiology) - Large conference focused on genomic epidemiology. Held every 2 years, next location TBD.

They also briefly touch on some mega conferences like ASM Microbe and ISMB, but note they tend to prefer the smaller, more focused meetings.

Key takeaways:

Conferences are great for networking and collaborating within your field

Smaller, topic-focused conferences allow you to connect with all attendees

Consider European/International conferences to expand your network

Dr Ozan Gundogdu from The London School of Hygiene and Tropical Medicine (LSHTM) and Dr Arnoud van Vliet from the University of Surrey join Andrew to chat about Campylobacter genomics and epidemiology. This was recorded at LSHTM.

This episode of the Bioinformatics Lab podcast discusses Campylobacter genomics and epidemiology. Campylobacter is a major cause of foodborne illness, with over 200,000 cases annually in the UK traced mainly to poultry. While genomic databases hold a wealth of Campylobacter sequences, undiscovered diversity likely remains. Research shows connections between virulence factors and sequence types, aiding epidemiological inference. In the UK, poultry and cattle are primary reservoirs leading to human infection, with minimal direct transmission. Control measures like chlorine washing of poultry can reduce levels but are banned in the EU over animal welfare concerns. Experts argue collaboration along the entire food chain is needed, along with ongoing research, to combat a pathogen that has evolved over millions of years.

In this episode, Kevin shares his experiences and key takeaways from the first PHA4Ge conference which has just been held in South Africa, focusing on genomic surveillance and pathogen genomics.

Kevin discusses the central theme of the conference: establishing and agreeing upon quality assurance standards for genomic surveillance. The need for unified standards across laboratories and countries is emphasized, as the current practice often leads to inconsistent approaches and results. The speaker notes that there has been progress in establishing quality control metrics for certain pathogens, such as SARS-CoV-2, through initiatives like PulseNet. However, there is acknowledgment that more work is needed for other organisms.

Kevin also touches upon computational tools for pathogen genomics and highlights several talks and presentations, including those focusing on bioinformatics tools for non-tuberculous mycobacteria, data platforms from CZI and NCBI, and infrastructure solutions such as the Terra platform.

A key takeaway from the conference is the importance of collaboration and communication within the global network of practitioners working in genomic surveillance. The speaker emphasizes the ethical considerations surrounding data sharing, data governance, and data sovereignty, which were major topics during the conference.
