Effects of binary metal combinations on zinc, copper, cadmium and lead uptake and distribution in Brassica juncea.

The interaction between lead, copper, cadmium and zinc in their binary combinations was investigated in Indian mustard seedlings (Brassica juncea L. var. Malopolska).

[Influence of Lactobacillus casei on biofilm formation by enteroaggregative Escherichia coli strains isolated from irritable bowel syndrome (IBS)].

Introduction: Many pathogenic bacterial species have the ability to biofilm formation. In our study we determined the influence of Lactobacillus casei on biofilm formation by enteroaggregative Escherichia coli (EAEC) strains obtained from irritable bowel syndrome patients.

Methods: The ability of EAEC isolates to biofilm formation was assessed in the presence of various concentrations of the probiotic L.

Association of untypeable enteropathogenic Escherichia coli (EPEC) strains with persistent diarrhea in children from the region of lower Silesia in Poland.

Enteropathogenic Escherichia coli strains (EPEC) carrying the eae gene encoding intimin are divided into typical strains producing bundle forming pili, encoded by the bfpA gene, and atypical strains lacking the gene. In the study typical and atypical EPEC that did not agglutinated with EPEC polyvalent antisera but carrying virulence factors characteristic to other pathogenic E. coli i.
