Herpesviruses are a large family of DNA viruses. Elephant Endotheliotropic Herpesviruses (EEHVs) are classified in the genus Proboscivirus family Herpesviridae and fall into 7 genotypes. The EEHVs, and in particular EEHV-1, are the cause of an acute haemorrhagic disease in young Asian elephants (Elephas maximus) and account for a significant amount of fatalities in juvenile Asian elephants. Herd screenings have revealed a widespread prevalence of the viruses and their periodical reactivation and shedding.
It is been documented that EEHV viraemia is detectable days before clinical symptoms. However, no drug with proven efficacy is currently available and lack of progress on virus culture has so far made a conventional vaccine an uncertain and far reaching goal.
Immunological control of herpesviruses is achieved by both the innate and adaptive immune responses. In the innate antiviral immune response, anti-viral interferons (IFNs), macrophages and natural killer (NK) cells have key roles in the containment of herpesvirus infections, whereas the role of gamma/delta T cells remains unclear as is their existence and distribution in elephants. This PhD study therefore aims to assess key components of the Asian elephant’s immune system that could be used to control the infection. Specifically we want to characterise some interferon genes and determine NK and T cells responses to establish targets for a suitable vaccine and other control strategies.
The project will be carried out in collaboration with the Animal and Plant Health Agency (www.gov.uk/apha) and the successful candidate will be mainly working at their Weybridge labs.
