lostridium difficile has been identified as a significant agent of diarrhoea and enterocolitis in both foals and adult horses. Hospitalization, antibiotic therapy or changes in diet may contribute to the development of C. difficile infection. Horses admitted to a care unit are therefore at greater risk of being colonized. The aim of this study was to investigate the carriage of C. difficile in hospitalized horses and the possible influence of some risk factors in colonization. During a seven-month period, faecal samples and data relating the clinical history of horses admitted to a veterinary teaching hospital were collected. C. difficile isolates were characterized through toxin profiles, cytotoxicity activity, PCR-ribotyping, antimicrobial resistance and multilocus sequence typing (MLST). Ten isolates were obtained with a total of seven different PCR-ribotypes, including PCR-ribotype 014. Five of them were identified as toxinogenic. A high resistance to gentamicin, clindamycin and ceftiofur was found. MLST revealed four different sequencing types (ST), which included ST11, ST26, ST2 and ST15, and phylogenetic analysis showed that most of the isolates clustered in the same lineage. Clinical history suggests that horses frequently harbour toxigenic and non-toxigenic C. difficile and that in most cases they are colonized regardless of the reason for hospitalization; the development of diarrhoea is more unusual.

Increasing age, several co-morbidities, environmental contamination, antibiotic exposure and other intestinal perturbations appear to be the greatest risk factors for C. difficile infection (CDI). Therefore, hospitalized patients are considered particularly vulnerable to CDI. The main objective of this study was to evaluate the prevalence of C. difficile in a Spanish hospital and to characterize the isolates with respect to the PCR-ribotype, antibiotic resistance and toxin activity. In addition, multilocus sequence typing (MLST) was performed in order to study clonal relationships between C. difficile isolates obtained from two different countries. Culture of samples was performed in a selective medium cycloserine cefoxitin fructose cholate. An identification of the isolated colonies was done by PCR detection of tpi, tcdA, tcdB and cdtA genes. Toxic activity was confirmed by a cytotoxic immunoassay. Further characterization was performed by PCR ribotyping. MLST was used in order to determine genetic relationships between Spanish and Belgian C. difficile isolates recovered from hospital patients in both countries. C. difficile was frequently detected in hospitalized patients. The isolates belonged to different PCR ribotypes, including type 027. Most of the strains obtained harboured tcdA and tcdB genes. The number of positive faecal samples considerably increased among elderly patients over 65 years old. The multi-locus sequence typing (MLST) analysis showed that some Spanish and Belgian isolates cluster in the same lineage. This study reveals the circulation of toxigenic C. difficile in a Spanish hospital. The relatedness between Belgian and Spanish isolates indicate a common source or a lack of diversity from some PCR-ribotypes. Moreover, data obtained suggest that the combination of ribotyping and MLST is a good tool for the inter-laboratory comparison of strains among different countries. Continuous inter-country surveillance is suitable to understand the spread of C. difficile isolates among hospitalized patients. [less ▲]

A profilometer which takes advantage of polarization states splitting technique and monochromatic light projection method as a way to overcome ambient lighting for in-situ measurement is under development [1, 2]. Because of the Savart plate which refracts two out of axis beams, the device suffers from aberrations (mostly coma and astigmatism). These aberrations affect the quality of the sinusoidal fringe pattern. In fringe projection profilometry, the unwrapped phase distribution map contains the sum of the object’s shape-related phase and carrier-fringe-related phase. In order to extract the 3D shape of the object, the carrier phase has to be removed [3, 4]. An easy way to remove both the fringe carrier and the aberrations of the optical system is to measure the phases of the test object and to measure the phase of a reference plane with the same set up and to subtract both phase maps. This time consuming technique is suitable for laboratory but not for industry. We propose a method to numerically remove both the fringe carrier and the aberrations. A first reference phase of a calibration plane is evaluated knowing the position of the different elements in the set up and the orientation of the fringes. Then a fitting of the phase map by Zernike polynomials is computed [5]. As the triangulation parameters are known during the calibration, the computation of Zernike coefficients has only to be made once. The wavefront error can be adjusted by a scale factor which depends on the position of the test object. [less ▲]

Une revue de la littérature sur les rapports entre agriculteurs et entreprises agro-industrielles, entre betteraviers et fabricants de sucre… tourne le plus souvent autour d’histoires entre humains, sur des questions de rapports de forces économiques, politiques, ou sociales et culturelles. Mais quid de ce qui les rassemble : ici, la betterave elle-même ? Cela peut paraître trivial, mais s’attacher « réellement » à cette dernière permet de comprendre d’une manière différente et pourtant essentielle leurs pratiques professionnelles. En choisissant de mettre l’accent sur la « carrière » de la betterave sucrière, l’objectif est à la fois de montrer la ténacité et la méticulosité du rapport que betteraviers et sucriers entretiennent avec cette dernière lorsqu’ils ont à se coordonner pour sa valorisation économique. Pourquoi passer par un non humain ? Parce qu’aux dires des acteurs eux-mêmes, c’est là que « les choses se jouent… ». Plusieurs éléments remarquables attachés à l’étude de cas proposé viennent mettre en valeur cet argument : - La betterave peut être considérée comme une des premières plantes industrialisées : elle repose sur un dispositif de coordination très poussé entre agriculteurs et industries. Une de ses manifestations les plus évidentes est celle du fonctionnement de ces « laboratoires de campagnes » : lieu technicisé de la rencontre entre deux mondes où les passions entre les protagonistes s’expriment de la manière la plus forte ; - l’évolution des manières de mesurer la richesse en sucre de la betterave (protocoles et contrôles) à entraîner l’évolution (voir la création) identitaire à la fois, des acteurs en présence (surtout du côté des agriculteurs avec la création d’un syndicat betteravier) et de la betterave sucrière elle-même (dont on a dû découvrir, pour les besoins de la cause, la répartition des concentrations en sucre en son sein ; ce qui a profondément modifié l’organisation sociale, technique et contractuelle à l’intérieur des laboratoires ou se réalise l’analyse des livraisons à la sucrerie) ; - le fait d’avoir un corps à corps avec de la matière vivante entraîne des incertitudes à la fois techniques et humaines : comment évaluer « objectivement » cette richesse en sucre ? - l’élaboration du protocole d’analyse polarimétrique de la richesse en sucre qui est encore aujourd’hui (plus d’un siècle et demi après) utilisée dans le monde entier, a accompagné la création de l’Association Belge de Chimie ! (ce qui témoigne de l’intérêt économique que cette élaboration technique pouvait avoir); L’idée (méthodologique) que j’aimerais ainsi faire passer chez le lecteur, c’est que s’intéresser à ce qui pourrait passer pour un rapport anecdotique au fonctionnement d’une filière agro-industrielle – à savoir la mise au point d’un protocole chargé « de faire parler la betterave » – est, au contraire, incontournable afin de comprendre l’évolution à la fois sociale, institutionnelle, politique et économique de ce secteur, mais également de la composition même des acteurs d’une société tout entière (la création de syndicats et d’associations professionnelles, l’évolution des rapports avec des ministères, etc.).
