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 105 bacterial cells/well (106/ml), which is comparable with or outperforms other(More)
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.(More)
Immunological response related to photodynamic therapy (PDT) is one of the basic elements that influence on the efficiency of this cancer treatment method. Diamino acid derivatives of protoporphyrin IX are promising photosensitizing agents that are intended to be the components of new anti-tumor drug. The influence of three derivatives - PP(Ser)(2)Arg(2),(More)
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. Expression of O54(More)
