Infectious diseases continue to threaten the sustainability, productivity and growth of the poultry industry worldwide and some present a risk to public health. Many are also present in wild bird populations, with the potential to spill over into domestic birds. This meeting capitalises on the success of the previous Microbiology Society Focused Meeting entitled ‘Pathogenesis and Molecular Biology of Avian Viruses’ and expands the remit to include bacteria and parasites. In addition, while the meeting will continue to incorporate reports of molecular and cell biology, pathogenesis and host response, it will be expanded to include molecular epidemiology, host genetics, host range, and control. This will bring together the scientific community to help find solutions to the biggest challenges in avian infectious diseases and provide a forum for discussion not only on individual pathogens, but also on cross-cutting areas of relevance to multiple infections, for example the effect of immunosuppression on secondary infections, microbiota-pathogen interactions, and multivalent vaccines against several infections.

Key topics
  • Molecular and Cell Biology
  • Molecular Epidemiology
  • Pathogenesis and host response
  • Host Genetics
  • Host Range
  • Control
Organising committee:
  • Holly Shelton (The Pirbright Institute, UK)
  • Andrew Broadbent (The Pirbright Institute, UK & University of Maryland, USA)
  • Roberto La Ragione (University of Surrey, UK)
  • Fiona Tomley (Royal Veterinary College, UK)
Further information will be announced in the build up to the meeting on our social media channels and you can follow us on Twitter @MicrobioSoc using the hashtag #Avian21.

Oliver Pybus
Oliver Pybus

Oliver Pybus is Professor of Evolution & Infectious Disease at the University of Oxford and Professor of Infectious Diseases at the Royal Veterinary College London. He is co-Director of the Oxford Martin School Program for Pandemic Genomics and editor-in-chief of Virus Evolution. He investigates the evolution and genetics of viruses and helped to establish the field of phylodynamics. This year he has been working on the genomic epidemiology of SARS-CoV-2 and contributes to COG-UK (the COVID-19 Genomics UK Consortium).

Helena Maier

Helena completed a DPhil at the Sir William Dunn School of Pathology, University of Oxford studying the function of the Influenza A virus polymerase complex. After this she moved to the Institute for Animal Health/The Pirbright Institute to study modulation of cellular autophagy by avian coronavirus, Infectious Bronchitis Virus (IBV) and formation of virus replication sites. She progressed to senior post-doctoral researcher and Independent Fellow at The Pirbright Institute focussing on coronavirus-host cell interactions using IBV vas a model virus. Helena now leads the Coronavirus-cell interactions group. Her group focusses on understanding how coronaviruses change the cellular environment to benefit replication and where there is conservation across the coronavirus family. This understanding will inform future development of vaccines, antivirals, and viral surveillance. A major area of research is the function and formation of virus induced membranous replication organelles. Other interests include viral regulation of translation and stress responses, viral budding and exit and coronavirus cross-species transmission. Her group now works on a wide range of coronaviruses including SARS-CoV-2 and other human viruses.

Androniki Psifidi

Androniki Psifidi

Androniki Psifidi is a Senior Lecturer in Veterinary Clinical Genetics at the Royal Veterinary College and a visiting researcher at the Roslin Institute (University of Edinburgh). Androniki is a member of the editorial board of Frontiers in Genetics and Frontiers in Veterinary Science, and a member of several consortia on poultry genomic resources.  Her work aims to dissect the genetic architecture and study the underlying molecular mechanisms of animal resistance to important diseases including zoonoses.  She is involved in multiple UKRI, EU, BMGF, charity and industry funded projects, where quantitative genetics, genomics, functional genomics and microbiome data is integrated in order to develop novel strategies to control disease. Translation of her research could lead to identification of disease biomarkers, novel drug-target discovery, and development of genomic tools with predictive capacity to underpin selective breeding, diagnostic testing and preventative disease management in both farm and companion animals. Visit her group’s website.

Damer Blake

Following a PhD focused on bacterial genetics from the University of Aberdeen, Damer began working with Eimeria species parasites in 2001 at the Institute for Animal Health (IAH, UK). During his time at IAH he carried out fundamental and applied genetics-led research, contributing to the Eimeria genome sequencing consortium and working towards new, cost-effective anticoccidial vaccines. Damer joined the Royal Veterinary College in 2010, becoming Professor of Parasite Genetics in 2016. Current research strands include population genetic analyses of recognised and cryptic Eimeria species, development of novel vaccine delivery strategies, understanding the genetic basis of host resistance to coccidiosis and interactions of Eimeria with bacterial microbiota of poultry. In 2017 Damer became Editor-in-Chief of the journal Avian Pathology.

Alasdair Nisbet
Alasdair Nisbet
Alasdair Nisbet is Head of the Vaccines and Diagnostics Department at Moredun Research Institute and has 31 years of research experience in veterinary and medical parasitology and in insect physiology. Throughout this time his research focus has been on novel methods of controlling invertebrate pests and parasites with an emphasis on understanding and exploiting the unique physiology of parasites of veterinary significance. He has national and international funding from Scottish Government, EU, UKRI and industry partners and has fruitful collaborations with academic, public sector and stakeholder groups worldwide (e.g. USDA, NFUS, Meat and Livestock Australia). His current work on avian pathogens encompasses the development of tools for understanding the poultry red mite’s biology, investigating gene function and host:parasite interactions and, ultimately, developing new ways of controlling the parasite, for example with vaccines. He recently led the international expert group delivering the DISCONTOOLS assessment for poultry red mite.
