Nasal carriage of methicillin-resistant Staphylococcus aureus (MRSA) among Swiss veterinary health care providers: detection of livestock- and healthcare-associated clones.

We screened a total of 340 veterinarians (including general practitioners, small animal practitioners, large animal practitioners, veterinarians working in different veterinary services or industry), and 29 veterinary assistants for nasal carriage of methicillin-resistant Staphylococcus aureus (MRSA) and Staphylococcus pseudintermedius (MRSP) at the 2012 Swiss veterinary annual meeting. MRSA isolates (n = 14) were detected in 3.8 % (95 % CI 2.1 - 6.3 %) of the participants whereas MRSP was not detected. Large animal practitioners were carriers of livestock-associated MRSA (LA-MRSA) ST398-t011-V (n = 2), ST398-t011-IV (n = 4), and ST398-t034-V (n = 1). On the other hand, participants working with small animals harbored human healthcare-associated MRSA (HCA-MRSA) which belonged to epidemic lineages ST225-t003-II (n = 2), ST225-t014-II (n = 1), ST5-t002-II (n = 2), ST5-t283-IV (n = 1), and ST88-t186-IV (n = 1). HCA-MRSA harbored virulence factors such as enterotoxins, β-hemolysin converting phage and leukocidins. None of the MRSA isolates carried Panton-Valentine leukocidin (PVL). In addition to the methicillin resistance gene mecA, LA-MRSA ST398 isolates generally contained additional antibiotic resistance genes conferring resistance to tetracycline [tet(M) and tet(K)], trimethoprim [dfrK, dfrG], and the aminoglycosides gentamicin and kanamycin [aac(6')-Ie - aph(2')-Ia]. On the other hand, HCA-MRSA ST5 and ST225 mainly contained genes conferring resistance to the macrolide, lincosamide and streptogramin B antibiotics [erm(A)], to spectinomycin [ant(9)-Ia], amikacin and tobramycin [ant(4')-Ia], and to fluoroquinolones [amino acid substitutions in GrlA (S84L) and GyrA (S80F and S81P)]. MRSA carriage may represent an occupational risk and veterinarians should be aware of possible MRSA colonization and potential for developing infection or for transmitting these strains. Professional exposure to animals should be reported upon hospitalization and before medical intervention to allow for preventive measures. Infection prevention measures are also indicated in veterinary medicine to avoid MRSA transmission between humans and animals, and to limit the spread of MRSA both in the community, and to animal and human hospitals.

Outbreak of Morel's disease in a Swiss goat flock

Staphylococcus aureus subsp. anaerobius is the causative agent of Morel’s disease in goats and sheep. We report the first outbreak of Morel’s disease in a Swiss goat flock. Multilocus sequence typing revealed that the Swiss isolates belong to sequence type (ST)1464, which is the ST responsible for outbreaks worldwide.

Evolution of methicillin-resistant Staphylococcus aureus (MRSA)

In 2009, a monitoring survey on the prevalence and genetic diversity of methicillin-resistant Staphylococcus aureus (MRSA) in slaughter pigs in Switzerland was started and revealed the presence of an unusual Multi Locus Sequence Type (ST49), which was detected for the first time in slaughter pigs worldwide. In addition to ST49, pigs also harboured ST398 and ST1. The prevalence of MRSA in slaughter pigs in Switzerland increased from 2.0% (95%CI 0.9-3.9) in 2009 to 5.9% (95% CI 3.8-8.7) in 2010, and remained stable in 2011 with 5,6% (95% CI 3.6-8.4). The increase was mainly due to the spread of ST398-t034, whereas ST49 was less frequently detected in 2010 and 2011. The presence of a specific sequence type (ST49) in MRSA from Switzerland suggests that it has been selected in local pig husbandry. However, MRSA of this lineage seems to have a lower potential for dissemination than ST398, which is increasingly detected in Swissslaughter pigs.

From Framework to Action: The DESIRE Approach to Combat Desertification

It has become increasingly clear that desertification can only be tackled through a multi-disciplinary approach that not only involves scientists but also stakeholders. In the DESIRE project such an approach was taken. As a first step, a conceptual framework was developed in which the factors and processes that may lead to land degradation and desertification were described. Many of these factors do not work independently, but can reinforce or weaken one another, and to illustrate these relationships sustainable management and policy feedback loops were included. This conceptual framework can be applied globally, but can also be made site-specific to take into account that each study site has a unique combination of bio-physical, socio-economic and political conditions. Once the conceptual framework was defined, a methodological framework was developed in which the methodological steps taken in the DESIRE approach were listed and their logic and sequence were explained. The last step was to develop a concrete working plan to put the project into action, involving stakeholders throughout the process. This series of steps, in full or in part, offers explicit guidance for other organizations or projects that aim to reduce land degradation and desertification.

Bereitschaft zu Interprofessionellem Lernen bei Studierenden der Medizin und der Pflege

Fragestellung/Einleitung An der Universität Bern haben die Medizinstudierenden des 1. und 2. Jahres die Möglichkeit mit Pflegestudierenden zusammen ein Wahlpraktikum zu bestreiten. Hierbei stellen sich die Studierenden gegenseitig ihre Curricula vor und verbringen gemeinsam je einen Halbtag in beiden Bildungseinrichtungen. Mit dem RIPLS (readiness for Interprofessional learning scale) wollten wir die Bereitschaft der Studierenden vor und nach dem Wahlpraktikum erfassen und diese mit je einer Kontrollgruppe der beiden Studiengänge vergleichen. Methoden Als Messinstrument wählten wir die Readiness for Interprofessional Learning Scale (RIPLS). Da noch keine validierte deutsche Übersetzung der RIPLS existiert, haben wir die 19 items zu zweit übersetzt und mehrfach überarbeitet. Am Wahlpraktikum nahmen 15 Medizin- und 11 Pflegestudierende teil. Die Kontrollgruppen bestanden aus 34 Medizin- und 21 Pflegestudierenden. Die RIPLS wurden vor und unmittelbar nach dem Wahlpraktikum verteilt und eingesammelt. Ergebnisse Die Resultate der Befragung zeigen, dass sich die Antworten der Medizin- und Pflegestudierenden in der Tendenz sehr ähnlich sind. In der Regel sind alle inklusive die beiden Kontrollgruppen positiv zum interprofessionellen Lernen eingestellt. Nur bei einzelnen Items, die das Rollenverständnis der beiden Berufsgruppen betreffen, waren grössere Unterschiede erkennbar. Die Antworten vor und nach dem Wahlpraktikum unterscheiden sich nicht wesentlich. Diskussion/Schlussfolgerung Sowohl Medizin- als auch Pflegestudierende haben eine positive Haltung gegenüber interprofessionellen Lernen, unabhängig davon, ob sie sich für eine entsprechendes Wahlpraktikum gemeldet haben oder nicht. Die Teilnahme am Wahlpraktikum verändert diese Haltung jedoch nicht wesentlich. Dies kontrastiert mit den sehr positiven spontanen Rückmeldungen der Studierenden beider Studiengänge. Es stellt sich darum die Frage, ob die RIPLS das geeignete Messinstrument ist, um die Effekte eines interprofessionellen Wahlpraktikus zu erfassen. Literaturhinweise: [1] Parsell G, Bligh J.

How much management is enough? Stakeholder views on forest management in fire-prone areas in central Portugal

With the increasing pressure to improve the contribution of forests to help dealing with global changes, it is critical to understand the different perceptions of those involved in the forest. How do forest owners, managers and members of local communities who often depend on the forest, value it and what are the problems affecting the forests in terms of being able to meet these new challenges? In Portugal, this task has taken on an even greater priority as more than 90% of the forest is private and forest management relies on the individual decisions of thousands of forest owners. To understand stakeholder views on forest and forest management, a transversal social perception survey was implemented in the form of a case study of central Portugal which included decision-makers, local technicians, forest owners and the general public. The results show that there is a consensus on the main issues affecting forests and forest management. A shift from classic forest owners to the emergence of indifferent forest owners was observed, although this shift has not been recognized by the forest owners in the survey, who maintain the individual management of their properties.

Does outmigration lead to land degradation? Labour shortage and land management in a western Nepal watershed

In Nepal, changing demographic patterns are leading to changes in land use. The high level of outmigration of men in the hills of Kaski District, Western Development Region of Nepal, is affecting the household structure but also land management. Land is often abandoned, as the burden on those left behind is too high. How do these developments affect the state of the land in terms of land degradation? To find out, we studied land degradation, land abandonment caused by outmigration, and existing sustainable land management practices in a subwatershed in Kaski District. Mapping was done using the methodology of the World Overview of Conservation Approaches and Technologies (WOCAT). While previous studies expected land abandonment to exacerbate slope erosion, we demonstrate in this paper that it is in fact leading to an increase in vegetation cover due to favourable conditions for ecosystem recovery. However, negative impacts are several, including the increase of invasive species harmful to livestock and a decline in soil fertility. Traditional land management practices such as terraces and forest management exist. To date, however, these measures fail to take account of the changing population dynamics in the region, making the question of how migration and land degradation are linked worth revisiting.

Deficiency of ECHS1 causes mitochondrial encephalopathy with cardiac involvement.

OBJECTIVE Short-chain enoyl-CoA hydratase (ECHS1) is a multifunctional mitochondrial matrix enzyme that is involved in the oxidation of fatty acids and essential amino acids such as valine. Here, we describe the broad phenotypic spectrum and pathobiochemistry of individuals with autosomal-recessive ECHS1 deficiency. METHODS Using exome sequencing, we identified ten unrelated individuals carrying compound heterozygous or homozygous mutations in ECHS1. Functional investigations in patient-derived fibroblast cell lines included immunoblotting, enzyme activity measurement, and a palmitate loading assay. RESULTS Patients showed a heterogeneous phenotype with disease onset in the first year of life and course ranging from neonatal death to survival into adulthood. The most prominent clinical features were encephalopathy (10/10), deafness (9/9), epilepsy (6/9), optic atrophy (6/10), and cardiomyopathy (4/10). Serum lactate was elevated and brain magnetic resonance imaging showed white matter changes or a Leigh-like pattern resembling disorders of mitochondrial energy metabolism. Analysis of patients' fibroblast cell lines (6/10) provided further evidence for the pathogenicity of the respective mutations by showing reduced ECHS1 protein levels and reduced 2-enoyl-CoA hydratase activity. While serum acylcarnitine profiles were largely normal, in vitro palmitate loading of patient fibroblasts revealed increased butyrylcarnitine, unmasking the functional defect in mitochondrial β-oxidation of short-chain fatty acids. Urinary excretion of 2-methyl-2,3-dihydroxybutyrate - a potential derivative of acryloyl-CoA in the valine catabolic pathway - was significantly increased, indicating impaired valine oxidation. INTERPRETATION In conclusion, we define the phenotypic spectrum of a new syndrome caused by ECHS1 deficiency. We speculate that both the β-oxidation defect and the block in l-valine metabolism, with accumulation of toxic methacrylyl-CoA and acryloyl-CoA, contribute to the disorder that may be amenable to metabolic treatment approaches.

A systematized workflow for assessing land resources using readily available spatial datasets

Land degradation as well as land conservation maps at a (sub-) national scale are critical for pro-ject planning for sustainable land management. It has long been recognized that online accessible and low-cost raster data sets (e.g. Landsat imagery, SRTM-DEM’s) provide a readily available basis for land resource assessments for developing countries. However, choice of spatial, tempo-ral and spectral resolution of such data is often limited. Furthermore, while local expert knowl-edge on land degradation processes is abundant, difficulties are often encountered when linking existing knowledge with modern approaches including GIS and RS. The aim of this study was to develop an easily applicable, standardized workflow for preliminary spatial assessments of land degradation and conservation, which also allows the integration of existing expert knowledge. The core of the developed method consists of a workflow for rule-based land resource assess-ment. In a systematic way, this workflow leads from predefined land degradation and conserva-tion classes to field indicators, to suitable spatial proxy data, and finally to a set of rules for clas-sification of spatial datasets. Pre-conditions are used to narrow the area of interest. Decision tree models are used for integrating the different rules. It can be concluded that the workflow presented assists experts from different disciplines in col-laboration GIS/RS specialists in establishing a preliminary model for assessing land degradation and conservation in a spatially explicit manner. The workflow provides support when linking field indicators and spatial datasets, and when determining field indicators for groundtruthing.

Guidelines for WB3 Part III: Stakeholder workshop 2: Selection and decision on prevention and mitigation strategies to be implemented

These guidelines were developed in the context of working block 3 of the DESIRE project. They address the facilitators in the 18 DESIRE study sites and support them in conducting stakeholder workshops aiming at the selection and decision on mitigation strategies to be implemented in the study site context. The decision-making process is supported by a multi-objective decision support system (MODSS) Software called 'Facilitator'.

A methodology for appraising and selecting strategies to mitigate desertification based on stakeholder participation and global best practices

The main aim of the methodology presented in this paper is to provide a framework for a participatory process for the appraisal and selection of options to mitigate desertification and land degradation. This methodology is being developed within the EU project DESIRE (www.desire-project.eu/) in collaboration with WOCAT (www.wocat.org). It is used to select promising conservation strategies for test-implementation in each of the 16 degradation and desertification hotspot sites in the Mediterranean and around the world. The methodology consists of three main parts: In a first step, prevention and mitigation strategies already applied at the respective DESIRE study site are identified and listed during a workshop with representatives of different stakeholders groups (land users, policy makers, researchers). The participatory and process-oriented approach initiates a mutual learning process among the different stakeholders by sharing knowledge and jointly reflecting on current problems and solutions related to land degradation and desertification. In the second step these identified, locally applied solutions (technologies and approaches) are assessed with the help of the WOCAT methodology. Comprehensive questionnaires and a database system have been developed to document and evaluate all relevant aspects of technical measures as well as implementation approaches by teams of researchers and specialists, together with land users. This research process ensures systematic assessing and piecing together of local information, together with specific details about the environmental and socio-economic setting. The third part consists of another stakeholder workshop where promising strategies for sustainable land management in the given context are selected, based on the best practices database of WOCAT, including the evaluated locally applied strategies at the DESIRE sites. These promising strategies will be assessed with the help of a selection and decision support tool and adapted for test-implementation at the study site.

Where the land is greener - experiences contributing to sustainable land management

There are numerous positive experiences that contribute to sustainable land management – but this wealth of information is often not tapped, and commonly not even recognised. The World Overview of Conservation Approaches and Technologies (WOCAT) is a network and a methodology with the aim of sharing this valuable knowledge to improve livelihoods and the environment. Forty-two promising case studies were recently documented and analysed in a global overview book entitled ‘where the land is greener’ (WOCAT 2007), from which a consolidated list of policy points were drawn. This paper highlights some of these conclusions and policy points.
