The results of our study showed both a worrying percentage of strains of Salmonella Enteritidis resistant to nalidixic acid and of strains of Salmonella Typhimurium with a pattern of resistance to four antibiotics or more. Surveillance of antimicrobial resistance should carry on and improve in order to be able to evaluate the control measures carried out for decreasing resistance in Salmonella, specifically that addressed to the prudent use of antimicrobial agents by farmers and veterinarians.

The Sierra Madre del Sur, Oaxaca is considered an area with high diversity of ecosystems, and low levels of fragmentation due to human disturbance. An indigenous people, the Zapotecs, have inhabited this area for centuries and Zapotec communities have used and continue to make use of local resources for their subsistence. Agroforestry systems provide timber, firewood, and non-timber forest products to local communities. Despite the ecological and cultural relevance of this region, basic information about local practices of management and harvesting are lacking. Little is known about the possible effects of these practices on biodiversity conservation. The objectives of this study were: to determine the local uses of forest wood resources in the municipality of San Agustín Loxicha, to determine the tree species most used by the inhabitants of this municipality and to discuss the implications of this management in the conservation of plant cover in this Priority Terrestrial Region. The reported main use of tree species was firewood, obtained by gathering dry branches and bark, as well as by felling dead trees. To a lesser extent, tree species are used to build houses and make furniture. Local people collect trees from the surrounding vegetation, so the richness and abundance of tree species in the area surrounding each community will always influence the ability of the communities to meet their needs. These practices do not have drastic effects on plant cover, mainly in areas of established forests. These traditional practices are involved in an empirical strategy to conserve and manage local resources.

Particleboard containing 20% Eucalyptus nitens, and MDF consisting of 100% Eucalyptus nitens wood were produced industrially at two plants owned by the company MASISA S.A. Normal production parameters for Pinus radiata were maintained. The particleboard produced had the same mechanical and physical properties that MASISA S.A. achieves under normal conditions for Pinus radiata. The MDF panels containing E. nitens did not reach industrial standards. Further investigations are necessary to achieve the required mechanical and physical property standards for MDF boards. The investigation of the properties of these panels indicated that with some process corrections, it will be possible to produce MDF using Eucalyptus nitens.

Care paths for the maternal and infant populations are used to define immediate and long-term outcomes related to care received in the home. This article describes a care path developed by public health nurses for intervention with an at-risk maternal-child population in a city/county health department. A public health nursing care management model provided the framework for developing this care path to foster cost-effective use of limited resources. It is crucial that public health nurses articulate clearly the services provided in the home both for those who may seek service and for policy makers who determine funding structure. The project demonstrated that care paths for home visitation involving high-risk prenatal clients are useful tools that streamline documentation, foster consistency and continuity of care, facilitate quality improvement efforts, and provide outcome data.
