How to Start Up a National Wildlife Health Surveillance Programme.

Whilst multiple countries in Europe have wildlife health surveillance (WHS) programmes, they vary in scope. In many countries, coordinated general surveillance at a national scale is not conducted and the knowledge of wildlife health status in Europe remains limited. Learning lessons from countries with established systems may help others to effectively implement WHS schemes. In order to facilitate information exchange, the WHS Network of the European Wildlife Disease Association organised a workshop to both collate knowledge and experience from countries that had started or expanded WHS programmes and to translate this information into practical recommendations. Presentations were given by invited representatives of European countries with different WHS levels. Events that led to the start-up and fostered growth spurts of WHS were highlighted, including action plan creation, partnership formation, organisation restructuring and appraisal by external audit. Challenges to programme development, such as a lack of funding, data sharing, infrastructural provision and method harmonisation, were explored. Recommendations to help overcome key challenges were summarised as: understanding and awareness; cross-sectoral scope; national-scale collaboration; harmonisation of methods; government support; academic support; other funding support; staff expertise and capacity; leadership, feedback and engagement; and threat mitigation and wildlife disease management. This resource may enable the development of WHS programmes in Europe and beyond.

Resistance to carbapenems and other antibiotics in Klebsiella pneumoniae found in seals indicates anthropogenic pollution.

BACKGROUND: The beta-lactamase enzyme OXA-48 has spread widely in recent years in Enterobacteriaceae associated with man, disseminated primarily on incompatibility group L/M plasmids. OXA-48 confers resistance to carbapenems, important antimicrobials for treating highly resistant bacterial infections in humans. This enzyme has rarely been detected in bacteria from animals. Furthermore, the use of carbapenem compounds is not permitted in food-producing animals in Europe and to our knowledge has not been reported in food-producing animals globally. METHODS: Bacterial isolates from lesions in stranded, free-living, juvenile common seals (Phoca vitulina) were identified. Antimicrobial susceptibility testing and whole genome sequencing analysis were used to characterise antimicrobial resistance genes carried by the bacteria. RESULTS: Here, we report the detection of Klebsiella pneumoniae subspecies pneumoniae carrying the bla OXA-48 gene on an incompatibility group L/M plasmid from an infection in a common seal. CONCLUSION: Evidence is accruing that marine mammals may be infected with bacteria originating from anthropogenic sources, such as human sewage, contaminating the environment.

Has respiratory cryptosporidiosis spread to black grouse Tetrao tetrix?

Infection by Cryptosporidium baileyi was first confirmed in red grouse in northern England in 2010 and within three years spread to 48 per cent of moors. These form the last English stronghold for the rarer black grouse, and given the rapid spread of respiratory cryptosporidiosis among red grouse, concern has been expressed about possible infection. In 2010, the authors started screening black grouse for cryptosporidiosis in (1) dead birds taken for postmortem examination, (2) sample birds caught at night and (3) an observational study of birds attending leks. Between 2011 and 2016, five males were sent for postmortem examination, of which three had suspected cryptosporidiosis. No disease was found in one; the second had extensive, subacute to chronic sinusitis; and the third had severe sinusitis and unilateral conjunctivitis. PCR analysis detected cryptosporidial DNA in the third bird only; however, the parasite was not seen in stained preparations or on histopathology. No cryptosporidiosis clinical signs were observed in 69 birds caught at night or in 170 birds attending leks. The authors have no conclusive evidence that cryptosporidiosis is causing sinusitis in black grouse. However, a single positive cryptosporidia PCR result from an affected bird does raise the possibility that they may be infected with the parasite.
