2017 International Journal for Parasitology

We have carried out a population genetic study of liver fluke and link our findings with the impact this could have on the emergence and spread of drug resistance.

2016 Scientific Reports

We have used models to assess the potential effect a vaccine would have on controlling liver fluke.

2015 Preventive Veterinary Medicine

We assessed the epidemiology of Fasciola hepatica on high-yielding dairy herds and the impact infection had on production.

2015 Parasitology

We determined that Fasciola hepatica from naturally infected sheep and cattle in Great Britain are diploid.

2014 Cattle Practice

Members of the liver fluke group have written an overview on liver fluke for veterinary practitioners which will be published in Cattle Practice later this year, as well as being available on the COWS website.

2014 Parasitology

Professor Diana Williams co-wrote a recent review for Parasitology advocating a change in how we use diagnostics to evaluate the impact of Fasciola hepatica infection on productivity of dairy and beef cattle.  The review also evaluates the likely effects of climate change on the epidemiology of fluke.  The paper highlights the need for research to develop non-chemotherapeutic management options, alongside more targeted use of anthelmintics, in the face of growing flukicide resistance and a changing pattern of disease.

2013 Parasitology

Dr Jane Hodgkinson was invited to write a review for a special edition of Parasitology to highlight her recent £700,000 BBSRC-funded project. The review summarizes the current understanding of drug resistance to the commonly used drug, triclabendazole, in Fasciola hepatica. The context for the project involves discussing the currently available genomic and genetic resources for F. hepatica. It then describes the generation of new genomic resources and subsequent non-biased approach to mapping the major genetic loci involved in conferring triclabendazole resistance in phenotyped F. hepatica populations.

2012 Nature Communications

In 2012, research by the liver fluke group was published in Nature Communications. The study found that if cattle are infected with liver fluke we are not reliably able to diagnose infection with bovine tuberculosis (TB). Bovine TB has a major economic impact on milk and meat production and seriously impacts on the UK’s export market as well as being a zoonotic disease. This finding may compromise the government’s planned eradication programme for bovine TB in the UK, which is currently costing the tax payer about £100 million per year.
