Prevalence and Antimicrobial Resistance of in Different Raw Food from Reynosa, Tamaulipas, Mexico.

() is an opportunistic foodborne pathogen that causes listeriosis in humans and animals, reaching up to 30% case mortality. There are only a few reports in Mexico about the strains found in various foods. The aim of this study was to determine the prevalence of , serogroups, virulence genes, and antimicrobial resistance in different foods from Reynosa, Tamaulipas, Mexico.

Gene Variants Identified in Mexican Patients with Alopecia Areata.

Alopecia Areata (AA) is a multifactorial, dermatological disease characterized by non-scarring hair loss. Alterations in candidate genes, such as (Hairless), could represent a risk factor for its development. The aim of this study was to search for and analyze variants in exons 3, 15 and 17 of the gene in Mexican patients with AA.

Flocculation and Expression of Genes of a Mezcal Strain with High Stress Tolerance.

Mezcal is a distillate produced by spontaneous fermentation of the must obtained from stalks of spp. plants that are cooked and pressed. Agave must contains a high amount of fructose and phenolic compounds, and fermentation usually occurs under stressful (and uncontrolled) environmental conditions.

The effect of hexose ratios on metabolite production in Saccharomyces cerevisiae strains obtained from the spontaneous fermentation of mezcal.

Mezcal from Tamaulipas (México) is produced by spontaneous alcoholic fermentation using Agave spp. musts, which are rich in fructose. In this study eight Saccharomyces cerevisiae isolates obtained at the final stage of fermentation from a traditional mezcal winery were analysed in three semi-synthetic media.
