Résumé : International audience
Ciguatera Fish Poisoning (CFP) is a non-bacterial seafood poisoning well characterized in the remote archipelagos of French Polynesia, yet poorly documented in the Society archipelago, most notably on Moorea, the second most populated island in French Polynesia, which counts a high proportion of fishermen fishing on a regular basis. To address this knowledge gap, a holistic study of the ciguatera issue was conducted on Moorea. First, ciguatera risk was analysed in terms of incidence rate, fish species most commonly involved and risk stratification in Moorea lagoon based on 2007–2013 epidemiological data. A mean incidence rate of 8 cases per 10,000 inhabitants for the study period and an average under-reporting rate of 54% were found. Taking into account hospitalization and medication fees, and loss of productive days, the health-related costs due to CFP were estimated to be USD $1613 and $749 for each reported and unreported case, respectively, with an overall cost of USD $241,847 for the study period. Comparison of the present status of CFP on Moorea with a risk map established in the late 1970’s showed that the spatial distribution of the risk has stayed relatively stable in time, with the north shore of the island remaining the most prone to ciguatera. Evaluation of the current knowledge on CFP among different populations groups, i.e. fishermen, residents and visitors, was also conducted through direct and indirect interviews. About half of the fishermen interviewed were actually able to identify risky fishing areas. While, overall, the CFP risk perception in the fishing community of Moorea seemed accurate, although not scientifically complete, it was sufficient for the safe practice of their fishing activities. This may be due in part to adaptive responses adopted by 36% of the fishermen interviewed, such as the avoidance of either high-risk fishing sites or toxic species. At the residents and visitors’ level, the study points out a striking lack of awareness of the CFP issue among visitors, as compared to local residents. Indeed, less than 25% of Moorea visitors vs. an average of 98% in residents were aware of CFP or of its presence on the island. Interestingly, evaluation of the fish consumption preferences showed that 70% of visitors do not consume lagoon fish during their stay, not for fear of CFP, but mainly due to the lack of availability of these species in recreational facilities or because they have nutritional preference for pelagic fish. This lack of awareness, along with the report by several CFP patients of the consumption of fish species yet banned for sale, stress the need for improved communication efforts on this critical issue among both residents and visitors on Moorea. The implementation of a public outreach strategy is proposed, based on both existing information networks and low-cost communication actions through information displays at various strategic locations, e.g. Tahiti-Faa’a international airport, the ferry boat station, recreational facilities, as well as the major trading points on Moorea Island.

Résumé : International audience
Portable microbial samplers are useful for detecting microorganisms in the air. However, limited data are available on their performance when sampling airborne biological agents in a routine practice. We compared bacterial and fungal concentrations obtained in field conditions using three impactor samplers with different designs (AES Chemunex Sampl'Air, bioMérieux Air Ideal, and Sartorius AirPort MD8/BACTair). The linearity of mold collection was tested in the range of 100 L to 1000 L, and all the devices had a correlation coefficient higher than 0.95. For optimal comparison of the samplers, we performed experiments in different hospital rooms with varying levels of air biocontamination. Each sampling procedure was repeated to assess reproducibility. No significant difference between the samplers was observed for the mold concentrations on Sabouraud agar, whereas Sampl'Air collected significantly more bacteria on tryptic soy agar than Air Ideal or BACTair at one of the sites. Impactor location in the room was nevertheless associated with the variability observed with the three samplers at the highest microbial concentration levels. On the basis of their performance, autonomy and simplicity of use, these three impactors are suitable for routine indoor evaluation of microbial air contamination.

Résumé : En l’espace de trente ans, la petite île de Saint-Barthélemy (25 km²) est sortie de son isolement séculaire pour s’imposer parmi les grandes destinations du tourisme de luxe dans le monde. Dans le cadre de cette étude, l’idée est d’identifier les éléments structurels et les différents facteurs conjoncturels qui permettent de comprendre la situation touristique de Saint-Barthélemy. L’exiguïté du territoire en lui-même peut être perçue comme un handicap fondamental ou, inversement, comme un atout considérable. Tout dépend du projet de développement. Il faut savoir tirer profit des spécificités du territoire considéré. Dans le cas de Saint-Barthélemy, l’exiguïté favorise la rareté et cette rareté convoitée n’est accessible qu’aux personnes les plus argentées. La rareté convoitée conduit au luxe. L’isolement est relatif : cette destination n’est pas accessible aux avions gros porteurs, l’essentiel du marché aérien est contrôlé par deux petites compagnies locales et l’espace aérien est ouvert aux petits avions privés. Le luxe ne se décrète pas, il ne se planifie pas. Le tourisme de luxe, c’est l’élection d’un territoire par des élites qui s’y retrouvent pour jouir de leur fortune à l’écart du monde.
Within thirty years, the small island of Saint-Barthelemy (25 km²) is out of its secular isolation to be among major luxury tourism destinations in the world. In this study, the idea is to identify structural element and different cyclical factors that help to understand Saint-Barthelemy tourism situation. The small size of the territory itself can be seen as a fundamental handicap or, conversely, as a considerable asset. Everything depends on development project. It is necessary to know how to take advantage of specific characteristics of this type of territory. In Saint-Barthelemy case, scarcity is coveted; this coveted rarity is accessible only for rich people. The coveted rarity leads to luxury. Isolation is relative: this destination is not accessible to the jumbo jets. The airline market is controlled essentially by two small local companies and the airspace is open to charter flies and private aircrafts. Some other companies provide more or less regular flights from nearby airports of San Juan (Puerto Rico), Sint-Maarten and Guadeloupe. Luxury cannot be decreed, it is not planned. Luxury tourism is the election of a territory by elites who gather there to enjoy away from the rest of the world.

Résumé : The Costa Maya is a vernacular coastal region of southeastern Quintana Roo (Mexico) and adjacent Ambergris Cay, Belize. As Mexico’s Caribbean coast suffered many growth pains associated with mass tourism development in Cancun and along the Riviera Maya, the Costa Maya by contrast was projected for more sustainable development including low-density housing and ecotourism. Development so far has been concentrated in Puerto Costa Maya, where a cruise ship pier and terminal were built in 2001. The nearby beach resort (balneario) of Majahual became dependent upon the 10-12 shiploads of tourists that descended upon it every week. In spite of big development plans, the more remote beaches of the Costa Maya cater to fewer, but well-heeled ecotourists and dive tourists. Hurricane Dean made landfall in August 2007 as a category-5 storm, and economic recovery only began in late 2008 when the cruise ship pier re-opened and Majahual rebuilt. As of late 2009, the cruise-ship traffic had still not recovered to pre-Dean levels, and a global recession coupled with swine-flu and drug violence scares has lowered U.S. tourism to Mexico. To what degree new tourism infrastructure such as an international airport at Tulum, a proposed causeway from Chetumal to the beach, and a new resort complex at Xahuayxel will stimulate tourism on the Mexican Costa Maya and eventually lead to a coastal highway link with San Pedro, Belize is still unknown.
La Costa Maya est une région côtière du sud du Quintana Roo (Mexique), proche de l'îlet Ambergris au Bélize. Contrairement à la côte caribéenne du Mexique qui a souffert du développement du tourisme de masse à Cancun et le long de la Riviera Maya, la Costa Maya s'est orientée vers un développement durable avec notamment une faible densité de construction et le développement de l'écotourisme.Le développement s'est concentré autour de Puerto Costa Maya où un terminal de croisière a été construit en 2001. La station balnéaire (balneario) de Majahual est devenue dépendante des 10-12 bateaux de touristes qui débarquaient chaque semaine. En dépit d'importants plans de développement, les plages reculées de la Costa Maya accueillaient tout au plus des écotouristes aisés et du tourisme lié à la plongée sous-marine.Le cyclone Dean, de catégorie 5, a dévasté le paysage en août 2007 et le rétablissement économique n'a pu être entamé que fin 2008, après la réouverture du terminal de croisière et la reconstruction de Majahual. Fin 2009, le trafic de croisière n'a pas retrouvé son niveau d'avant Dean et la récession mondiale couplée avec la grippe porcine et les violences liées à la drogue ont fait diminuer le tourisme en provenance des Etats-Unis. On ignore à quel niveau les nouvelles infrastructures tels l'aéroport international de Tulum qui propose un itinéraire de Chetumal à la plage et le nouveau complexe hôtelier à Xahuayxel, stimuleront la Costa Maya mexicaine créant peut-être une autoroute côtière reliée à San Pedro au Bélize.
