The incidence of extended-spectrum β-lactamases (ESBLs) was analyzed in Enterobacteriaceae population circulating in the Upper Silesian Child and Mother Health Center in Katowice (USC&MHC). Altogether 1164 clinical specimens, collected from children hospitalized in 8 different hospital units of USC&MHC were investigated. Five hundred and eighty-five clinical isolates of the family Enterobacteriaceae...
Group B streptococcus causes infections in woman during pregnancy and confinement, perinatal infections in newborns related to mothers carrier-state and in adults, mostly in the elderly, with one or more predisposing to infections conditions. Diabetes mellitus is the most common underlying condition. The aim of the study was to determine the frequency of GBS occurrence and GBS antibiotic susceptibility...
The association between the presence of self-splicing intron Ca.LSU and proteolytic activity of Candida albicans isolates was tested. Study included 95 C. albicans strains isolated from gastrointestinal tract of diabetes children. The strains with the intron (genotype B) displayed a significantly higher proteolytic activity (385.2 ± 192U/L) than did strains without intron (genotype A) (119 ± 115U/L)...
Presence of specific IgM, IgG and IgA antibodies against Chlamydia pneumoniae was evaluated in children aged 1 week to 36 months to investigate the role of C. pneumoniae in respiratory infections and other diseases. Serum samples were obtained from 150 hospitalized children, including 123 children presenting the clinical symptoms of various respiratory tract infections, two children with acute diarrhoea,...
An association between Helicobacter infection and autoimmune hepatitis (AIH) in children was investigated. The prevalence of antibodies to H. pylori did not differ between the AIH and the control group, (22% versus 14%), and antibodies to non-gastric Helicobacter were not detected in either group. H. pylori DNA was found in two AIH liver tissues, but Helicobacter was not cultured from any sample.
Although integrons by themselves are not mobile, due to their presence in plasmids and transposons, they can be transferred horizontally. For these reasons integrons are a major mechanism for the spread and maintenance of multidrug resistance (MDR). This study describes the distribution of integron gene cassette classes in a collection of uropathogenic Escherichia coli (UPEC) isolated from children...
This study analysed the pattern of antibiotic resistance in 251 Campylobacter strains isolated from symptomatic children hospitalized in 4 large paediatric hospitals in Poland from 2000 through 2007. The highest resistance was found for ciprofloxacin (49.5% for C. jejuni and 51.3% for C. coli), followed by tetracycline (17.5% and 18.0%, respectively), and ampicillin (13.2% and 10.2%, respectively)...
Respiratory Syncytial Virus (RSV) is one of the most common causes of lower respiratory tract infections in young children, immunocompromised patients (children and adults), patients with chronic respiratory diseases and elderly people. Reinfections occur throughout the life, but the severity of disease decreased with subsequent infection. The aim of this study was to analyze the frequency of RSV...
Gut microbiota was analyzed in children, aged 6–18 months and su$ering from atopic dermatitis before and after 3 month supplementation of their diet with Lactobacillus casei DN – 114001 in a dose of 10⁹ cells daily. On completion of this period the total number of fecal Lactobacillus sp. cells decreased from 7.86 Log₁₀ CFU/g to 6.40 Log₁₀ CFU/g. After the next 5 months (without dietary supplementation...
The aim of the study was to analyze the differences in the activity of β-glucuronidase and β-glucosidase in stool specimens of children with Inflammatory Bowel Diseases (IBD) and healthy subjects. The disease activity was determined according to the PCDAI scale (Crohn disease) and Truelove-Witts scale (Ulcerative colitis). Enzyme activity was determined by spectrophotometry. There was a correlation...
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.e. diffusely...
There is a 10–30% prevalence of HP infection in the general pediatric population in Poland. This study aimed to determine its prevalence in T1DM children in Upper Silesia, Poland and estimate its influence on metabolic control of patients. We studied 149(82♀) children with T1DM (duration > 12 months, mean HbA1c) and 298(164♀) age-matched controls. In all cases height and weight z-scores and Cole’s...
The resistance of microorganisms to antibiotics has become a serious issue in recent years in the therapy of bacterial infections. This problem also concerns the treatment of infections caused by Helicobacter pylori strains. The aim of this study was to evaluate the frequency of primary resistance of H. pylori strains isolated from children and adults. The subject of the research was 105 strains of...
The gold standard in microbiological diagnostics of bacteremia is a blood culture in automated systems. This method may take several days and has low sensitivity. New screening methods that could quickly reveal the presence of bacteria would be extremely useful. The objective of this study was to estimate the effectiveness of these methods with respect to blood cultures in the context of antibiotic...
