Visible light induced photocatalytic inactivation of bacteria (Escherichia coli, Staphylococcus aureus, Enterococcus faecalis) and fungi (Candida albicans, Aspergillus niger) was tested. Carbon-doped titanium dioxide and TiO2 modified with platinum(IV) chloride complexes were used as suspension or immobilised at the surface of plastic plates. A biocidal(More)
Lactobacilli, the predominant vaginal microorganisms in healthy premenopausal women, control other members of the vaginal microflora and thus protect against bacterial vaginosis and urinary tract infections. It has been claimed that some lactobacilli are also protective against Candida vaginitis. Little is known, however, about the mechanisms by which these(More)
Macrolide resistance in 169 Streptococcus agalactiae [group B streptococcus (GBS)] isolates originating from pregnant carriers was investigated. Using multiplex PCR the presence of genes encoding erythromycin resistance and capsular polysaccharides, as well as surface proteins, was determined. Random amplification of polymorphic DNA (RAPD) and PFGE were(More)
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)
BACKGROUND This multicentre, randomised, double-blind, placebo-controlled trial was performed to determine whether the use of oral probiotic preparation (prOVag®) containing three Lactobacillus strains together with standard metronidazole treatment and also targeted antibiotic treatment (following the failure of metronidazole therapy) could reduce the(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 This study investigated a possible role of Escherichia coli in propagation and perpetuation of the chronic inflammation in ulcerative colitis (UC). The lesions of UC are located superficially on the rectal and/or colonic mucosa. It is suggested that the commensal bacteria of the digestive tract may play a role in the pathogenesis of UC. Several(More)
Probiotics discussed in this paper are evaluated using the WHO/FAO definition from 2001. The authors present a brief description of the normal microbiota of the gastrointestinal tract, discuss probiotics in the aspects of gut immunity and then move to selection of bacterial strains as probiotics. The main issue raised is the critical evaluation of(More)
AIM To assess the mucosa-associated bacterial microflora and mucus layer in adolescents with inflammatory bowel disease (IBD). METHODS Sixty-one adolescents (mean age 15 years, SD+/-4.13) were included in the study. Intestinal biopsies from inflamed and non-inflamed mucosa of IBD patients and from controls with functional abdominal pain were cultured(More)
Bacteria may exist in nature in a planktonic form or in biofilms that allow bacteria to survive in an unfriendly microenvironment. Biofilm is a structured community of bacteria hidden in a self-produced polymeric matrix of polysaccharides, proteins, and extracellular DNA. Biofilm-growing bacteria cause chronic infections, which are characterized by(More)
