Parasitology encompasses all diseases that are caused by parasites in animals and humans including parasites as vectors of disease. This is a multidisciplinary work area across APHA.

Parasitology work at APHA Veterinary Investigation Centres includes:

  • Endemic parasites diagnosis and surveillance
  • New and emerging parasite detection
  • Non-statutory zoonotic parasite disease investigation
  • Anthelmintic resistance investigation
  • Providing consultancy and samples for research
  • Coccidial oocyst identification
  • Larval differentiation of Trichostrongyle-type eggs
  • Differential staining¬† for Haemonchus spp eggs
  • Some import and export testing on companion animals

The work carried out at APHA feeds into the Species Expert Groups, the Veterinary Risk Group (VRG) and Human Animal Infections and Risk Surveillance Group (HAIRS) as appropriate. 

There are an additional two sites within APHA that carry out parasitology work

APHA Sand Hutton:

  • Parasitology research projects
  • Exotic parasites of wildlife surveillance (Trichinella and Echinococcus spp)
  • Endemic parasite and anthelmintic resistance research
  • Risk assessments and modelling

APHA Weybridge:

  • Vectors and vector-borne parasite research and surveillance (Babesia and Theileria spp vector competence studies)
  • Protozoan and helminth expertise
  • Import and export testing on companion animals and horses
