Damer is Professor of parasite genetics. His research interests are focused on protozoan parasites and pathogens of poultry using genetics and molecular biology.

Damer graduated with a degree in Animal Science from Wye College (University of London) in 1997. Following an MSc in Pig Production, he completed a PhD in bacterial genetics, both at the University of Aberdeen. After the completion of his PhD in 2001 he took up a post at the Institute for Animal Health (IAH) working on avian coccidiosis caused by the protozoan Eimeria species. During his time at IAH he carried out fundamental and applied genetics-led research, contributing to the Eimeria genome sequencing consortium, developing reverse-genetics strategies for use with Eimeria, designing a series of new molecular diagnostic tools and using genetic mapping as a step towards development of a new generation of cost-effective anticoccidial vaccines. In 2010 Damer joined the 51³Ô¹ÏÍø, where he was appointed professor in 2016. Damer is currently Editor-in-Chief of the journal Avian Pathology and a member of the executive committee of the World Veterinary Poultry Association.

Since joining the RVC Damer has extended his research interests in Eimeria - protozoan parasites with cause the disease coccidiosis in all livestock species, most notably poultry. These parasites can cause a severe enteritis and have been estimated to cost the global poultry production industry in excess of £10 billion per annum. Current research strands include continuing studies to map genetic loci that encode genuinely immunoprotective antigens as vaccine candidates and the development of Eimeria as a novel vaccine delivery vehicle (in collaboration with Prof. Fiona Tomley). More recently, Damer has developed research interests in Eimeria population genetics and genetic diversity, interactions of Eimeria with bacterial pathogens of poultry, parasite diagnostics, microbiomes and studies on parasite evolution in domestic and wild animals. Damer also works with a range of other apicomplexan parasites including Toxoplasma gondii and Cryptosporidium species, as well as the poultry red mite (Dermanyssus gallinae), and in the wider areas of poultry health and gut integrity.

  • Development of a poultry vaccine platform based on transgenic coccidia parasites and evaluation of immunoprotection against necrotic enteritis

    The sustainability of poultry meat and egg global production, paramount to respond the worldwide demand for food, is challenged by poultry enteric diseases such as coccidiosis and necrotic enteritis.

    his project aimed to develop a vaccine platform based on Eimeria parasites to protect chickens against pathogens of different origin. The first use to generate a prototype and evaluate a specific product against the re-emerging disease necrotic enteritis is expected to have future applications that could have a direct impact in human health by the targeting of zoonotic organisms that transfer disease from chickens to human, and which have importance in both high income and low-and-middle income countries (e.g. Campylobacter, Salmonella).

  • Optimising response to oral yeast-based vaccines against coccidiosis in chickens

    We aim to improve Saccharomyces cerevisiae as an oral vaccine vector platform for use with poultry, focusing on the economically significant disease coccidiosis. We have developed a yeast-delivery platform in which antigens from Eimeria can be expressed in a stable, non-secreted form, with the yeast itself acting as transport system and adjuvant.

  • SweetAnimals

    The SweetAnimal project studies the presence of sugar-binding receptors in the genomes of a variety of farmed animals, how these differ between species, what ligands expressed on pathogens they bind, and how this information can be used to develop carbohydrate-based vaccines.

  • UK Research and Innovation (UKRI) Global Challenges Research Fund (GCRF) One Health Poultry Hub

    With integrated streams of social, economic, biological, mathematical and policy-led research, we are co-producing detailed knowledge on the biological, structural and socio-economic factors that shape networks of chicken production and distribution. The RVC-led UKRI GCRF One Health Poultry Hub brings together leading laboratory, clinical, veterinary and social scientists, as well as skilled communications experts, programme support staff and external stakeholders.
