Wild Duck () as a Source of Antibiotic-Resistant subsp. O58-The First Report in Poland.

The "One Health" approach increasingly demonstrates the global spread of pathogenic microorganisms and their antimicrobial resistance in the environment, both in animals and humans. subsp. is nowadays very often isolated from cold-blooded reptiles to a lesser extent from sheep, but unfortunately more and more often from humans.

Plasmid- and chromosomal genes-encoded two separate O-polysaccharide chains of Salmonella Uccle (O:3,54)--structural elucidation.

The bacterium Salmonella Uccle belongs to serotype O:54 in the Kauffmann'a-White scheme. Group O:54 is unique among the serogroups belonging to the genus Salmonella. Normally, the enzymes involved in the biosynthesis of the repeating units of somatic antigen are encoded by a set of genes, located in the region of the bacterial chromosome.

[Phage types recognized within Salmonella Enteritidis strains isolated in Poland in 1996-2007].

Unlabelled: Phage typing carried out according to the well-defined schemes is still recommended as a standard, fast and inexpensive method for epidemiological investigations all over the world to control Salmonella infections. However, the method should be in the hands of well-trained staff. This means that it is generally limited to reference laboratories.

Specific detection of Salmonella enterica and Escherichia coli strains by using ELISA with bacteriophages as recognition agents.

The use of bacteriophages, instead of antibodies, in the ELISA-based detection of bacterial strains was tested. This procedure appeared to be efficient, and specific strains of Salmonella enterica and Escherichia coli could be detected. The sensitivity of the assay was about 10(5) bacterial cells/well (10(6)/ml), which is comparable with or outperforms other ELISA tests detecting intact bacterial cells without an enrichment step.
