The assumption that Mycobacterium tuberculosis infections should be considered clonally homogeneous has been weakened in the last few years. Recent studies have shown (i) the isolation of different M. tuberculosis strains from sequential episodes, (ii) mixed infections by two M. tuberculosis strains, and (iii) genetic variations in M. tuberculosis(More)
The composition of the vaginal microbiota is an important health determinant. Several members of the phylum Actinobacteria have been implicated in bacterial vaginosis, a condition associated with many negative health outcomes. Here, we present 11 strains of vaginal Actinobacteria (now available through BEI Resources) along with draft genome sequences.
Research on vaginal infections is currently limited by a lack of available fully sequenced bacterial reference strains. Here, we present strains (now available through BEI Resources) and genome sequences for a set of 14 vaginal isolates from the phylum Firmicutes These genome sequences provide a valuable resource for future research in understanding the(More)
The genus Lactobacillus daily generates a growing interest among microbiologists and technologists, who try to discover new biotechnological applications and probiotic properties. The main goal of this study was to evaluate the inhibitory capacity of Lactobacillus spp. against pathogens (Escherichia coli O157:H7, Salmonella spp., Staphylococcus aureus)(More)
This paper presents the theoretical basis and practical implications of the incorporation of learning objects to Higher Education learning architectures. Assuming that in order to improve their cost-effectiveness such architectures should benefit from the richness of resources that instructional digital libraries have available, the problem is found in(More)
Pigs are important reservoirs of Shiga toxin-producing Escherichia coli (STEC). The entrance of these strains into the food chain implies a risk to consumers because of the severity of hemolytic uremic syndrome. This study reports the prevalence and characterization of STEC throughout the pork production chain. From 764 samples, 31 (4.05%) were stx positive(More)
OBJECTIVE To determine the prevalence of depression and anxiety in main carers of dependent patients as defined by the Dependent Care Law 39/2006. MATERIAL AND METHODS We selected 294 main carers of dependent patients as defined by Law 39/2006, and performed a descriptive, cross-sectional and multi-centre study. They were recruited during the first(More)
