[Fimbriae as virulence factors of uropathogenic strains of Escherichia coli].

In this paper uropathogenic Escherichia coli strains are characterized. In particular, fimbrie as virulence factors are presented and their role in the clinical course of urinary tract infection is assessed.

[Molecular analysis of uropathogenic strains of Escherichia coli and the clinical course of urinary tract infection in children].

Unlabelled: The most frequent etiological factor of urinary tract infections are virulent Escherichia coli strains. Identification of uropathogenic Escherichia coli strains is possible using biomolecular techniques. THE PURPOSE OF THIS STUDY was to determine the prevalence of Escherichia coli strains encoding papG adhesins and adhesins of Dr family in children with urinary tract infections and to establish the relationship between the bacterial genotype and clinical course of a sickness.

Cytomegalovirus disease in neonates and infants--clinical presentation, diagnostic and therapeutic problems--own experience.

Background: The aim of the study was to present diagnostic problems, different clinical presentations and results of treatment of cytomegalovirus infections in neonates and infants.

Material/methods: The study was carried out in a group of 31 children from 10 days to 12 months of age (17 boys, 14 girls). The diagnosis was based on serological investigations (presence of specific IgM antibodies and/or increasing titer of IgG antibodies), presence of intermediate or early CMV antigen in peripheral blood leukocytes or positive blood or urine PCR results.
