Registered designation of origin areas of fermented food products defined by microbial phenotypes and artificial neural networks

Article Abstract:

Origin areas of fermented food products, including cheese from the milk of sheep and dry fermented sausage, can be determined by microbial phenotypes and artificial neural networks based on research done in Portugal. The study sought to find ways to confirm Registered Designation of Origin (RDO) certification. Counterfeit products could be detected. Metabolic profiles of Enterococcus and Lactobacillus were studied to determin the geographic origin and organoleptic type.

Environmental contamination with vancomycin-resistant enterococci from hospital sewage in Portugal

Article Abstract:

Vancomycin-resistant enterococci (VRE) were detected in samples of sewage obtained downstream of hospitals of Porto area in Portugal, and in samples from the Douro Estuary. Clonal analysis, Tn1546 typing, and presence of putative virulence traits indicate the clinical origin of these isolates.

Multiniche screening reveals the clinically relevant metallo-beta-lactamase VIM-2 in Pseudomonas aeruginosa far from the hospital setting: An ongoing dispersion process?

Article Abstract:

The screening study was conducted to determine the presence of metallo-beta-lactamases (IMP and VIM types and SPM-1) in isolates from different nonhospital sources. The results have indicated that the hospital setting was the possible origin of these [bla.sub.VIM-2]-carrying strains.
