Proposed attributes of national wildlife health programmes

Wildlife health is important for conservation, healthy ecosystems, sustainable development, and biosecurity. It presents unique challenges for national programme governance and delivery because wildlife health crosses not only jurisdictional responsibilities and authorities but also inherently spans multiple sectors of expertise. The World Organisation for Animal Health (OIE) encourages its Members to have wildlife disease monitoring and notification systems. Where national wildlife health surveillance programmes do exist, they vary in scope and size. Evidence-based guidance is lacking on the critical functions and roles needed to meet the OIE’s recommendations and other expectations of a national programme. A literature review and consultation with national wildlife health programme leaders identified five key attributes of national programmes including: (1) being knowledge and science based; (2) fostering cross-nation equivalence and harmonisation; (3) developing partnerships and national coordination; (4) providing leadership and administration of national efforts and (5) capacity development. Proposed core purposes include: (1) establishing and communication of the national wildlife health status; (2) leading national planning; (3) centralising information and expertise; (4) developing national networks leading to harmonisation and collaborations; (5) developing wildlife health workforces and (6) centralising administration and management of national programmes. A national wildlife health programme should aim to identify, effectively communicate, and manage the risk to or from a country’s wildlife populations. It should generate the appropriate knowledge required to improve the effectiveness of wildlife policies and systems, including identifyinhttp://www.oie.int/en/publications-and-documentation/scientific-and-technical-review-free-access/peer-reviewed-papers-for-the-plurithematic-review-2018/g and assessing emerging priorities, thus increasing warning for preparedness and preventive actions.

An outbreak of type C botulism in Herring Gulls (Larus argentatus) in Southeastern Sweden

From 2000 to 2004, over 10,000 seabirds, primarily Herring Gulls ( Larus argentatus ), died from an undetermined cause in the Blekinge archipelago in southeastern Sweden. In June 2004, 24 affected Herring Gulls were examined clinically, killed humanely, and 23 were examined by necropsy. Seven and 10 unaffected Herring Gulls collected from a local landfill site and from Iceland, respectively, served as controls. All affected birds showed similar neurologic signs, ranging from mild incoordination and weakness to severe flaccid paralysis of legs and wings, but generally were alert and responsive. All affected gulls were in normal nutritional condition, but were dehydrated and had empty stomachs. No gross or microscopic lesions, and no bacterial or viral pathogens were identified. Type C botulinum toxin was detected in the sera of 11 of 16 (69%) affected gulls by mouse inoculation. Type C botulism was the proximate cause of disease in 2004. Sera from 31% of birds tested from outbreaks in 2000 to 2003 also had detectable type C botulinum toxin by mouse inoculation. No large-scale botulism outbreak has been documented previously in this area. The source of toxin, initiating conditions, and thus, the ultimate cause of this outbreak are not known. This epidemic might signal environmental change in the Baltic Sea.
