Molecular Identification of Selected Strains Isolated from Mexican Tropical Soils and their Anti- Activity.

The increasing incidence of infections and resistance to current antifungal therapies has led to the search for new and more effective antifungal compounds. Actinobacterial species from the genus are recognized as some of the major producers of antimicrobial compounds. Therefore, the aims of this study were: (1) the identification of strains isolated from Mexican tropical acidic soils, (2) the evaluation of their antifungal activity on , and (3) the exploration of the presence of polyketide synthase genes in their genome and antifungal secondary metabolites in their extracts.

"Antimicrobial and antiproliferative activity of essential oil, aqueous and ethanolic extracts of Ocimum micranthum Willd leaves".

Background: Ocimum micranthum Willd is a plant used in traditional medicine practiced in the region of the Yucatan peninsula. In particular, it is used for the treatment of cutaneous infections and wound healing, however there are currently no existing scientific studies that support these applications. The aim of the present study was to evaluate the antimicrobial and the in vitro proliferative activity (on healthy mammalian cell lines) of the essential oil and extracts (aqueous and ethanolic) of this plant.

[Microbiological analysis of red octopus in fishing ports of Campeche, Mexico].

Objective: In this work we studied the microbiological quality of the red octopus given its important economic and social impact on the region South-Southeast of Mexico.

Materials And Methods: Samples were taken in different areas of capture of the species and analyzed with biochemical tests described in the Mexican official standards, identifying strains belonging to the genus Vibrio, Salmonella and faecal coliforms, and E. coli O157: H7.
