Osteochondrosis (OC) is common in large-breed dogs. According to the breeding guidelines of the Swiss kennel clubs, the shoulder joints are included in the radiographic screening for joint diseases in the Greater Swiss Mountain dog (GSMD) and the Border Collie (BC) since 1993 and 2003, respectively. The aim of this study was to estimate the overall prevalence of humeral head OC in these 2 breeds in Switzerland based on the data of the Swiss National Dysplasia Committees. All radiographs were re-evaluated to assess single radiographic changes. From 1993 and 2003, accordingly, until 2013, the overall prevalence was 14% for the GSMD and 8% for the BC, respectively. Affected joints showed a focally reduced opacity or a flattened/indented contour of the caudal section of the humeral head. Articular flaps were only seen occasionally. Degenerative joint disease was significantly more common in OC affected joints (GSMD: 32%; BC: 20%) than in joints without OC. The present study is the first report on the prevalence of humeral head OC in a large cohort of GSMD and the BC over a long study period. In comparison to other breeds, the herein reported prevalences are in the mid to upper range. Results of the present study should alert veterinarians to the disease in these breeds and may serve as a starting point for further epidemiological and genetic studies.

Objective To express the views of a working party held to consider antibiotic resistance surveillance systems, their strengths and weaknesses, and their current and future applications. Methods The participants, all of whom were experienced in this field, discussed the development of surveillance systems in relation to the increasing prevalence of resistance to antibacterial agents and the current interest in surveillance systems shown by many official bodies, in both the human and veterinary fields. The problems inherent in surveillance systems were considered together with the applications of different systems. Results The properties of good antibiotic resistance surveillance systems were defined. Surveillance systems vary widely from those with a narrow base, focusing on few organisms in one disease area, to those covering many diseases, many organisms (including normal flora) and many compounds. Whatever their design, they should be able to detect significant differences and shifts in susceptibility to various antibacterial agents, and the information derived from them should reach as many interested parties as possible in a timely manner. In using this information to decide strategies, criteria for action need to be determined by pragmatic consensus. Funding remains a major problem, with few large studies being supported by official bodies in spite of their professed enthusiasm for surveillance. In consequence, many current systems are funded by the pharmaceutical industry and are of necessity restricted in their focus. Conclusions Antibiotic resistance surveillance studies should and can be well planned and well executed. Many current systems suffer from well-recognized but uncorrected biases. Consortium funding will be necessary for large schemes to be successful. There is no 'ideal' surveillance system.
