The plasmidome of a Salmonella enterica serovar Derby isolated from pork meat.

The complete nucleotide sequences of four plasmids hosted by a Salmonella enterica serovar. Derby strain 6MK1 isolated from pork were determined by shotgun Sanger sequencing. A 107,637 base pairs (bp) conjugative plasmid pSD107 containing 150 putative coding sequences (CDS) could be assigned to the narrow host range incompatibility group IncI1.

Molecular basis and evolution of multiple drug resistance in the foodborne pathogen Salmonella enterica serovar Ohio.

The molecular basis and evolution of multidrug resistance were established for 54 isolates of Salmonella enterica serovar Ohio, recorded between 1991 and 2005 in Asturias, a northern region of Spain. All isolates were closely related, as shown by cluster analysis of XbaI-BlnI combined profiles. Of these, 33.

[Identification of bacteria through 16S rRNA sequencing: principles, methods and applications in clinical microbiology].

Phylogenetic relationships among prokaryotes can be inferred from comparisons of their 16S rRNA (or 16S rDNA) sequences. This has had an enormous repercussion on bacterial taxonomy, leading to the currently applied system of classification, and allowing a rapid and precise identification of bacteria. In clinical microbiology, molecular identification based on 16S rDNA sequencing is applied fundamentally to bacteria whose identification by means of other types of techniques turns out impossible, difficult, or requires a lot of time.
