BACKGROUND Multiple studies document that probiotics are effective in treating infectious diarrhoea in children. Lactobacillus rhamnosus GG is the most extensively studied but effectiveness of other strains has been poorly examined. AIM To determine whether L. rhamnosus strains (573L/1; 573L/2; 573L/3) (Lakcid L, Biomed, Lublin, Poland) would be effective(More)
Lactobacillus rhamnosus (573L/1-3) strains are considered effective in the treatment of rotaviral diarrhoea in children. The colonisation of the gastrointestinal (G.I.) tract by the Lactobacillus rhamnosus strains and the determining factors are discussed reporting data of a prospective, double-blinded, placebo-controlled randomized study in children(More)
In recent decades, the interest in probiotics as diet supplements or drugs has increased. In order to determine a specific bacterial isolate to be probiotic, it is necessary to describe precisely its probiotic characteristics and taxonomic properties, including the strain level. Most of the well-known genotyping methods were designed for the commonly-found(More)
Chronic active colitis (including inflammatory bowel disease - IBD) is maintained by a variety of pro-inflammatory mediators. Certain intestinal bacterial strains may induce colitis, whereas some strains (e.g. Lactobacillus spp.) show a protective effect in colitis owing to their anti-inflammatory activity. In this study, we have examined the production of(More)
OBJECTIVES Three clinical Acinetobacter baumannii isolates (A-C) were isolated from three separate patients during an outbreak in a hospital in Krakow, Poland. Isolate A was recovered first and was susceptible to carbapenems, whereas isolates B and C were resistant. The aim of this study was to investigate the differences in carbapenem susceptibility in(More)
BACKGROUND The aims of our study were analysis of the occurrence of infections by members of the Enterobacteriaceae family in 6 Polish neonatal intensive care units in 2009, their drug resistance, the epidemiology of extended-spectrum β-lactamase (ESBL)-producing strains and the possibility of using modern tools of microbiology diagnosis in infection(More)
OBJECTIVES The vaginal microflora is composed of many bacterial species and plays a major role in maintaining the balance of this complex environment. This study was conducted in order to assess the degree and persistence of the colonization of vaginal epithelium by strains from an orally administered mixture of lactobacilli, containing Lactobacillus(More)
BACKGROUND The aim of this study was to assess the prevalence of multidrug-resistant Escherichia coli and extended-spectrum â-lactamases (ESBL) pathogens isolated from asymptomatic bacteriuria and urinary tract infections (UTIs), and the relationship between the phylogeny, antimicrobial resistance, and virulence among isolates in residents of 3 long-term(More)
The objectives of the present study were to investigate the carbapenemase and metallo-beta-lactamase genes of Acinetobacter baumannii clinical isolates by polymerase chain reaction (PCR) and real time PCR and to determine the molecular epidemiology of the strains using the DiversiLab tool. From these data, correlations between drug resistance, resistance(More)
The aim of this study was to investigate the prevalence of plasmid-mediated quinolone resistance (PMQR) determinants in Escherichia coli from neonatal intensive care units (NICUs) in Poland. The study was conducted on 80 E. coli isolates from different types of infections collected between 2009 and 2012. Six (5%) isolates were not susceptible to(More)
