My work comprises the collection, isolation and identification of microorganisms, anti-biograms, from both the clinical and post-mortem examination specimens from various Wildlife Epidemiology Theme (WLE) projects and assisting in post-mortem examinations of wildlife. I maintain isolation and identification techniques for the Garden Wildlife Health (GWH) project, including isolating and identifying Trichomonassp. I conduct isolation and identification techniques for the Cetacean Strandings Investigation Programme (CSIP) , which monitors disease in cetaceans, pinipeds, basking sharks & turtles around the British Isles.
The microbiology laboratory also screens captive exotic animals in quarantine and from within the collections at London Zoo and Whipsnade Zoo. All reintroduction projects authorised by Natural England include a detailed veterinary management protocol. This consists of screening, clinical & post-mortem examination of endangered indigenous British species including red squirrel (Sciurus vulgaris), corncrake (Crex crex), red kite (Milvus milvus) common dormouse (Muscardinus avellanarius), field cricket (Gryllus campstris), red-barbed ants (Formica rufibarbis) and cirl bunting (Emberiza cirlus).
The laboratory provides technical support for molecular diagnostic studies of various amphibian species, looking for the chytrid fungus (Batrachochytrium dendrobatidis) and Ranavirus using Real-time PCR.
Finally, I manage several wildlife pathology archives (including frozen and formalin tissues and parasite samples) in posterity.
My research interests include isolating and identifying pathogenic microorganisms from wild animal population and comparative studies of micro-flora in wild-caught and captive-bred animals.
Our screening methods have led to advances in the practice of ‘parasite conservation’, where captive-bred animals destined for release are managed so that their natural complement of bacteria, viruses, worms and fungi are as similar to their wild cousins as possible. This reduces the risk of them encountering novel pathogens after release. It also reduces the need for medication during captivity which has been linked to resistance in parasites. These advances have led to improved veterinary protocols in breeding projects across the UK.
I am also interested in raptors and have studied haematozoa of falcons, normal and abnormal haematology of raptors and the haemo-response to therapeutics and disease in birds of prey.
