Happy New Year: A round up of all of the parasites we have seen this year

Happy New Year: A round up of all of the parasites we have seen this year We’ve been lucky enough to see quite a range of parasites at Ridgeway this year, including some new ones and some that we’ve encountered many times. We thought we would share a few of these with you to sum up some of our work this year. We look forward to seeing what new and exciting species 2021 brings us! Dictyocaulus filaria A new parasite…

Anthelmintics: When Should I Use a Wormer?

Anthelmintics: When Should I Use a Wormer? What are wormers? An anthelmintic, or wormer, is a drug which treats infections of parasitic worms. These could be nematodes — roundworms like Ascaradia galli in chickens, cestodes — tapeworms like Moniezia expansa in sheep, or trematodes — flukes like Calicophoron daubneyi in various livestock species. Anthelmintics are widely used across the globe, but misuse is leading to the growing issue of resistance. How do I know which wormer to use? Firstly, how do you know your animals need…

Quality monitoring of Liver fluke metacercariae

Quality monitoring of Liver fluke metacercariae At our laboratory part of the work we do is to maintain several colonies of snails, these are the intermediate host in the life cycle of the liver fluke Fasciola hepatica. The metacercariae we produce are supplied to Universities and Pharmaceutical Companies and used in research to gain a better understanding of the parasite, its control and the growing problem of its resistance to anthelmintic treatments. To ensure the metacercariae we supply to our customers…

The shifting nature of veterinary pharmaceutical R&D delivery…a new niche opportunity

The shifting nature of veterinary pharmaceutical R&D delivery…a new niche opportunity Increasingly, large pharmaceutical companies are evolving their business strategies and are incorporating outsourcing of R&D as a norm. Traditionally, large pharma companies would operate in house R&D activities. Nowadays, a multifaceted approach exists for delivering new technologies incorporating in house R&D activities; use of contract research organisations (CROs); and utilising venture capital funded start-up companies. Why are veterinary pharmaceutical companies moving to favour outsourcing of R&D? Companies are moving…
