The good, the bad and the ugly: framing debates on nature in a One Health community.

Originating in medical and veterinary spheres, the One Health concept stands as an open call for collaboration also between these disciplines or professions and those of environmental and social science. However, the communities of practice in question show uneasy or under-developed collaborations, due to a variety of factors. We argue that an important factor is the way issues are raised and questions are formulated, i.e., their framing. Based on complementary perspectives on health and knowledge, this overview provides an inter- and trans-disciplinary analysis of the role of the framing of « nature ¼ in One Health discourses as a barrier or a facilitator to collaboration, as revealed by the scientific literature. We find that the lack of reflection by scientists about the framing under which they operate appears as a major factor of misunderstanding between disciplines, and a barrier for inter- and trans-disciplinary solutions to improve management of health risks and benefits. Hence, to build such solutions, framing will have to be a conscious and repeated step in the process, acknowledging and explaining the diversity of viewpoints and values. The interdisciplinary dialogues inherent in this process promote translation between scientific domains, policy-makers and citizens, with a critical but pluralistic recourse to various framings of health risks and benefits associated with nature, and a deep awareness of their practical and ethical consequences.

Prevalence and risk factors for carriage of multi-drug resistant Staphylococci in healthy cats and dogs

We investigated the distribution of commensal staphylococcal species and determined the prevalence of multi-drug resistance in healthy cats and dogs. Risk factors associated with the carriage of multi-drug resistant strains were explored. Isolates from 256 dogs and 277 cats were identified at the species level using matrix-assisted laser desorption ionisation-time of flight mass spectrometry. The diversity of coagulase-negative Staphylococci (CNS) was high, with 22 species in dogs and 24 in cats. Multi-drug resistance was frequent (17%) and not always associated with the presence of the mecA gene. A stay in a veterinary clinic in the last year was associated with an increased risk of colonisation by multi-drug resistant Staphylococci (OR = 2.4, 95% CI: 1.1~5.2, p value LRT = 0.04). When identifying efficient control strategies against antibiotic resistance, the presence of mechanisms other than methicillin resistance and the possible role of CNS in the spread of resistance determinants should be considered.

[Evaluation of variable number of tandem repeats (VNTR) isolates of Mycobacterium bovis in Algeria]. / Evaluation des VNTR (variable number of tandem repeats) des isolats de Mycobacterium bovis en Algérie.

The discriminatory potency of variable number of tandem repeats (VNTR), based on 7 loci (MIRU 26, 27 and 5 ETRs A, B, C, D, E) was assayed on Mycobacterium bovis strains obtained from samples due to tuberculosis in two slaughterhouses in Algeria. The technique of MIRU-VNTR has been evaluated on 88 strains of M. bovis and one strain of M. caprea and shows 41 different profiles. Results showed that the VNTR were highly discriminatory with an allelic diversity of 0.930 when four loci (ETR A, B, C and MIRU 27) were highly discriminatory (h>0.25) and three loci (ETR D and E MIRU 26) moderately discriminatory (0.11
