The attracted wide audience participants including farmers, vets, academics, researchers other stakeholders. COEEML was developed address potential surveillance gaps extensively animals. Extensive management potentially makes regular or close inspection disease detection more challenging. described previous Vet Record Focus article1 information about it can be found at http://apha.defra.gov.uk/vet-gateway/surveillance/experts/exten-man-livestock.htm Following successful conferences workshops, engage stakeholders virtually. Feedback meetings had identified as one top three priorities livestock, alongside liver fluke sheep scab. APHA's role Fin Twomey, head Intelligence Unit, opened webinar, providing an overview work which includes collection, collation interpretation data identify new re-emerging threats, sharing these support appropriate action (the monthly reports articles are examples this). Changing tick epidemiology Paul Phipps, scientist based Weybridge Wildlife Zoonoses Vector Borne Disease Research Group, delivered first talk. He species Ixodes ricinus Haemaphysalis punctata (red tick) (Fig A), particularly their important vectors, how geographical range, abundance period activity seem changing UK.

TSS successfully threats non-native coming into example, travelling pets migratory birds. Tickborne cause illness were described, Lyme caused bacterium Borrelia burgdorferi (transmitted ricinus) encephalitis (TBE) virus. There 3000–5000 cases UK every year. TBE virus detected through study 2018/19, presence using deer sentinels. Katie Lihou, PhD student department parasitology ecology Bristol, gave her research prevalence cattle farms Great Britain.2 Analysis gathered farmer questionnaires indicated infestation unevenly distributed Britain, areas significantly elevated risk north Wales, north-west western Scotland. Overall, reporting 13 per cent 6 farms, but ‘hot-spot’ clusters ranged 48 100 farms. Upland farming, larger flock sizes being located south-west significant factors sheep.

She highlighted importance obtaining accurate diagnostic tests either postmortem blood samples. “There year Environmental limited, so acaricides treat when managing diseases.
