Molecular characterization of Treponema pallidum subsp. pallidum in Switzerland and France with a new multilocus sequence typing scheme

2018

Syphilis is an important public health problem and an increasing incidence has been noted in recent years. Characterization of strain diversity through molecular data plays a critical role in the epidemiological understanding of this re-emergence. We here propose a new high-resolution multilocus sequence typing (MLST) scheme for Treponema pallidum subsp. pallidum (TPA). We analyzed 30 complete and draft TPA genomes obtained directly from clinical samples or from rabbit propagated strains to identify suitable typing loci and tested the new scheme on 120 clinical samples collected in Switzerland and France. Our analyses yielded three loci with high discriminatory power: TP0136, TP0548, and TP…

Assessment of allyl isothiocyanate as a fumigant to avoid mycotoxin production during corn storage

2016

The occurrence of fungi and mycotoxins in foods modify sensorial properties and represents a health risk for consumers, and the use of natural antimicrobials may be an alternative to reduce this problem. The objective of this study was evaluate the potential of allyl isothiocyanate (AITC) in inhibit the production of mycotoxins in corn kernels by Aspergillus parasticus, Fusarium tricinctum, Fusarium verticillioides, Alternaria alternata and Gibberela zeae. Kernels were treated with gaseous AITC at 50, 100 or 500 μL/L during 48 h in hermetic flasks. Then, flasks were opened for 24 h and 100 g of corn were inoculated with 105 conidia/g of either fungal species. Flasks were kept at 23 °…

The many faces of human sociality: uncovering the distribution and stability of social preferences

2018

There is vast heterogeneity in the human willingness to weigh others' interests in decision making. This heterogeneity concerns the motivational intricacies as well as the strength of other-regarding behaviors, and raises the question how one can parsimoniously model and characterize heterogeneity across several dimensions of social preferences while still being able to predict behavior over time and across situations. We tackle this task with an experiment and a structural model of preferences that allows us to simultaneously estimate outcome-based and reciprocity-based social preferences. We find that non-selfish preferences are the rule rather than the exception. Neither at the level of …

Indirect majority and minority influence: An exploratory study

1991

In a 2 × 2 design, 85 subjects were asked to estimate the size of angles (direct influence) that were either 90 or 85°, after being confronted with incorrect judgements of a majority (88 per cent) or a minority (12 per cent) of people estimating the angles at 50°. Additionally, pre- and post-test measures were used to establish indirect influence on subjects' judgements pertaining to acute angles (i.e. on the estimation of the length of lines constituting the angles, and on the imaginary weight of figures represented by these angles). Overall, little direct influence is observed. This may partly be due to the introduction of a denial of the credibility of the source in all conditions. In fa…

El uso de GPS para el análisis del comportamiento espacio-temporal de los turistas. Pre-test en el Valle de Boí

2015

Este artículo es un análisis exploratorio sobre el uso de los GPS para estudiar el comportamiento de los visitantes en un espacio abierto. El Valle de Boí es un escenario turístico que ofrece diversos recursos de primer orden, por lo que el estudio de los recorridos de los visitantes permite analizar la respuesta a estímulos muy diferentes. Los resultados demuestran que el recurso del GPS en espacios abiertos permite ampliar la información sobre el uso social del espacio turístico y abre las puertas a nuevas formas de análisis. This article is an exploratory analysis of the use of GPS for the study of visitors’ behaviour in an open space. The Boi Valley is an open space that offers importan…
