Histomonosis, also commonly referred to as blackhead disease, is a disease that infects several known species of gallinaceous fowl. It is caused by the protozoan parasite Histomonas meleagridis and was first seen in Rhode Island in 1893. This parasite can cause mortality, particularly in turkeys, and has been found all over the globe in economically important avian species. In the 1970s Nitroimidazoles drugs were discovered to be effective in combatting the disease, and were used to treat histomonosis. Unfortunately, due to human health concerns, these drugs were banned for use on animals for human consumption in the EU and US initially (2002-2015), and then globally, as they were suspected of being carcinogens. The last drug to be banned was Nitarsone, in 2015, which was only available in the US at that time. Since then, there have been some attempts to produce drugs that are effective in preventing and treating H. meleagridis infections, whilst being safe for the consumer, nonetheless these have varied efficacies. Some of these include paramomycin (commonly used to treat coccidiosis) and Agricure Enteroguard, an essential oils-based product. Paramomycin and enteroguard mode of action on H. meleagridis and the reasons for the varied responses are unknown. Irrespective, blackhead disease continues to be a major challenge for the poultry industry with mortalities of more than 1 million turkeys reported/annum in the UK alone (Personal Communication, British Poultry Council). The aim of this project is to develop innovative solutions to treat blackhead disease in turkeys. This PhDt is a DFE CAST studentship partially funded by Aviagen and the British poultry council and the second supervisor is also based in the Agri-Food Biosciences instate, Northern Ireland. Therefore this project has a strong link to industry and government. This project will be well suited to students interested in microbiology/animal science/computational biology. A budget for training in necessary skills is available as part of the project.
The four objectives of the proposed research project are:
•Assess mode of action of both paramomycin and Enteroguard together or separately on H. meleagridis in vitro. A thorough review of approved drugs used to treat protozoal infections will be completed and added to an in vitro screen in order to check whether other viable options for treating the disease exist.
•Assess efficacy and mode of action of both paramomycin and Enteroguard on H. meleagridis in vivo. Turkeys with be infected with H. meleagridis, using facilities at AFBI, and subsequently affect of early and mid-disease treatment with either paramomycin and Enteroguard or both in combination at recommended dosages will be monitored. This study will allow mechanism of action to be elucidated.
•Assess efficacy and mode of action of ‘other’ potential treatments in vivo. This objective is open-ended and will largely depend on the outcomes of the desk search conducted in objective 1. Specifically, we will infect turkeys with H. meleagridis using facilities at AFBI and monitor effect of these during early and mid-phases of the disease as noted above.

The School of Biological Sciences provides PhD and MPhil (research degree) programmes in subjects ranging from basic biochemistry, molecular genetics and cancer research, to agricultural science, marine ecology and the economic evaluation of ecosystem services and food retailing. If you have a topic or research question in mind, please use the Find a Supervisor link (see Apply tab) to identify the most appropriate member of staff to support your idea. If not, don't worry, we regularly advertise funded projects and there is no harm in browsing our academic staff profiles for inspiration and then contacting whoever seems best: we are very open to applications from suitably qualified people interested in scientific research. In every case, a PhD or MPhil course provides the means of being part of a cutting edge scientific research team and contributing to genuine new discoveries or the development of new methods for practical use. If you cannot study full time, we offer pro-rata part time research degree programmes as well.
To help orientation, the School is organised into three research theme clusters:
- Ecosystem Biology and Sustainability
- Microbes and Pathogen Biology
- Food Safety and Nutrition
Ecosystem Biology and Sustainability:
In this cluster, you could research biodiversity and ecosystem services for environments ranging from tropical forests to deep oceans, using field techniques and skills such as wildlife tracking, taxonomy, geostatistics, molecular and genetic ecology, foodweb-analysis, microcosm and mesocosm experiments and mathematical/computational methods. Alternatively, you could study the behaviour and temperament of wild, agricultural or domestic animals and their implications for welfare and ability to respond to environmental change. Potential research projects include phylogenetic analysis of rare and newly discovered species, examination of ecological interactions in tropical systems, agricultural soils, or marine communities, using state-of-the-art genetic analysis, surveys using drones or satellite tagging, or experiments in tanks and field plots, including careful and ethical examinations of animal behaviour. Projects range from theoretical analysis of stability in ecosystems, through discovery of new species and mechanisms of interaction, or responses to climate change, to the assessment of EU agri-environment schemes, development of new methods for commercial fisheries management and economic evaluations of conservation measures. Projects very often have an international dimension and include collaboration with other researchers worldwide.
Microbes and Pathogen Biology:
This cluster covers a diverse array of research interests united by an emphasis on molecular approaches applied to both fundamental and applied questions over the range from molecular to ecological systems. These interests include biochemistry, food safety, microbiology and parasite control with applications in human and animal health, nutrition, plant and soil sciences, and agricultural development. We have a long-standing reputation in parasite biology and in applied microbiology (for example in clearing land of contamination) as well as strong contributions to fundamental methods in understanding cancer, developing veterinary vaccines and molecular detectors for toxins and diseases. The common thread is our strong molecular approach using and developing cutting edge genomic, transcriptomic/proteomic methods. Research students in this cluster enjoy a range of strong international links across Europe, Asia, North and South America.
Food Safety and Nutrition:
Research opportunities offered by this cluster span the entire food chain "from farm to fork" with a strong emphasis on food safety and nutrition, public health and food security. In this cluster you would conduct research under the supervision of leading scientists based in the Institute for Global Food Security and benefit from integration with business experts, helping you gain leadership positions nationally and internationally.

School of Biological Sciences
For a PhD you will have a principal and second supervisor who advise your independent studies and will be supported by a wider team from the academic staff - who they are, of course, depends on your project. For further details on any aspect of postgraduate research degrees within the School of Biological Sciences, contact: email@example.com.
A research degree offers students an opportunity to foster their capacity for independent research and critical thought. It also allows students to explore an area of interest and so understand and solve theoretical and practical problems within the field. Undertaking a research degree can enhance a student’s written and oral communication skills and a PhD is almost always a formal requirement for an academic post.
Assessment processes for the Research Degree differ from taught degrees. Students will be expected to present drafts of their work at regular intervals to their supervisor who will provide written and oral feedback; a formal assessment process takes place annually.
This Annual Progress Review requires students to present their work in writing and orally to a panel of academics from within the School. Successful completion of this process will allow students to register for the next academic year.
The final assessment of the doctoral degree is both oral and written. Students will submit their thesis to an internal and external examining team who will review the written thesis before inviting the student to orally defend their work at a Viva Voce.
Supervisors will offer feedback on draft work at regular intervals throughout the period of registration on the degree.
The minimum academic requirement for admission to a research degree programme is normally an Upper Second Class Honours degree from a UK or ROI HE provider, or an equivalent qualification acceptable to the University. Further information can be obtained by contacting the School.
For information on international qualification equivalents, please check the specific information for your country.
Evidence of an IELTS* score of 6.5, with not less than 5.5 in any component, or an equivalent qualification acceptable to the University is required (*taken within the last 2 years).
