Antimicrobial drug self-medication occurs most often in eastern and southern Europe and least often in northern and western Europe.

Background.Patients with blood disorders colonized with antibiotic-resistant bacteria (ARB) are prone to systemic infections that are difficult to treat. Reintroduction of commensal bacteria in a murine model of enterococcal colonization of the gut can lead to eradication of enterococci. We hypothesized that fecal microbiota transplantation (FMT) could be used to eradicate ARB in humans.Methods. Participants colonized with ARB were treated with intraduodenal FMT according to a prospective protocol (NCT02461199). The primary endpoint was complete ARB decolonization at 1 month after FMT. Secondary endpoints included safety assessment and partial ARB decolonization. Microbiome sequencing was performed to investigate the influence of microbial composition of the transplanted material on the outcome of FMT.Results. Twenty-five FMTs were performed in 20 participants (including 40% who had neutropenia) who were colonized by a median of 2 (range, 1-4) strains of ARB. The primary endpoint was reached in 15/25 (60%) of the FMTs and more frequently in cases in which there was no periprocedural use of antibiotics (79% vs 36%, P < .05). Among participants, 15/20 (75%) experienced complete ARB decolonization. There were no severe adverse events, and partial ARB decolonization was observed in 20/25 (80%) of the FMTs. The microbiota composition analysis revealed higher abundance of Barnesiella spp., Bacteroides, and Butyricimonas and greater bacterial richness in the fecal material, resulting in eradication of Klebsiella pneumoniae compared with nonresponders.Conclusions. FMT in patients with blood disorders is safe and promotes eradication of ARB from the gastrointestinal tract. Clinical Trials Registration. NCT02461199.

Nasopharyngeal carriage of Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis in 226 children in different settings (in a crèche [day care center], in an orphanage, and at home) during two seasons (winter and spring) was studied. The rates of carriage of S. pneumoniae and H. influenzae were markedly higher in the crèche and in the orphanage than in the home setting (e.g., 56.5, 63.3, and 25.9%, respectively, for S. pneumoniae in winter). Approximately 80% of the S. pneumoniae isolates identified in the crèche and in the orphanage belonged to the serotypes represented in the seven-valent pneumococcal vaccine, and 4.4% of the children were colonized by H. influenzae type b. Almost all H. influenzae isolates were fully susceptible to the antimicrobial agents tested, and only five (3.6%) produced ␤-lactamase; in contrast, 100% of the M. catarrhalis isolates were ␤-lactamase positive. Among S. pneumoniae isolates, 36.2% were nonsusceptible to penicillin (PNSP) and 11.8% were fully resistant to penicillin (PRP). All PNSP isolates were obtained from children at the crèche and at the orphanage but not among children brought up at home, and all PRP isolates showed a multiresistant phenotype. Colonization by PRP isolates correlated well with prior treatment with ␤-lactams. For the majority of children colonized at both sampling times, strain replacement of S. pneumoniae and H. influenzae was observed; long-term colonization by a single strain was rare.The nasopharynx of children is colonized by a broad variety of microorganisms, including such potential pathogens as Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. Well-known risk factors that promote bacterial carriage include overcrowding, e.g., due to attending day care centers (DCCs) (crèches) or residing in orphanages; frequent viral infections; and an excessive use of antibiotics (12). DCCs and orphanages have also been identified as places that promote the clonal spread of multiresistant strains; thus, healthy children represent an important reservoir of bacterial strains, in particular, S. pneumoniae, that are resistant to many antimicrobial agents. These strains are subsequently disseminated in the community by other contacts of colonized children, e.g., their siblings and parents. It is possible to limit the spread of H. influenzae type b and some serotypes of S. pneumoniae by vaccination, but studies of the impact of immunization on colonization have yielded discrepant results (5,11,14,22).Colonization of mucosal surfaces in the human respiratory tract represents a dynamic process in which bacteria are acquired, eliminated, and reacquired many times in a lifetime. Extensive and often excessive use of antibiotics can promote the replacement of strains susceptible to antimicrobial agents by resistant ones (12, 28). Moreover, the human nasopharynx is also often viewed as a place where frequent genetic exchange takes place due to such processes as transformation with foreign DNA, bacterial intra-and interspecies c...

Antibiotic resistance is an increasing community problem and is related to antibiotic use. If antibiotic use could be reduced, the tide of increasing resistance could be stemmed. e-Bug is a European project involving 18 European countries, partly funded by The Directorate-General for Health and Consumers (DG SANCO) of the European Commission. It aims to develop and disseminate across Europe a junior and senior school teaching pack and web site (hosting the lesson plans and complementary games) that teach young people about prudent antibiotic use, microbes, transmission of infection, hygiene and vaccines. The aim of e-Bug is to increase young people's understanding, through enjoyable activities, of why it is so important to use antibiotics correctly in order to control antibiotic resistance, and to have good hand and respiratory hygiene to help reduce the spread of infection. Within the senior school pack the sexual transmission of infections has also been included, as the peak age of chlamydial infection is in 16-24 year olds. Teachers, young people and the consortium of 18 countries were closely involved with agreeing learning outcomes and developing the resource activities. Young people helped create the characters and microbe artwork. The resources have been translated, adapted for and disseminated to schools across 10 countries in Europe, and endorsed by the relevant government departments of health and education. The web site has been accessed from >200 countries. The resources will be translated into all European Union languages, and have been used to promote European Antibiotic Awareness Day and better hand and respiratory hygiene during the influenza pandemic in 2009.

Dysbiosis plays a major role in the etiology of inflammatory bowel disease (IBD). Fecal microbiota transplantation (FMT) is a new promising option for IBD treatment. We aimed to assess the effectiveness of a two-week FMT course in children with IBD. Ten patients, 10-17 years of age with moderate to severe IBD received a course of eight doses of freshly prepared FMT via a naso-duodenal tube or gastroscopy. All of the patients had pancolitis. There were eight cases of ulcerative colitis (UC) and two of Crohn's disease (CD). Disease activity was evaluated using the Pediatric UC Activity Index (PUCAI) and Pediatric CD Activity Index (PCDAI) for UC and CD, respectively, CRP, and fecal calprotectin on the day before the first infusion and then on the day before the next course of FMT. Clinical response, defined as a decrease of 15 points in either index, was observed in 9/10 patients (seven UC and two CD). Clinical remission, defined as a PCDAI score ≤ 10 and PUCAI score < 10 measured at the same time point, was observed in 3/8 UC patients and 2/2 CD patients. Side effects observed were self-limiting and benign. We conclude that a short, intensive course of FMT has a beneficial effect on UC and CD colitis. FMT was well-tolerated and safe. Nonetheless, an optimal protocol of FMT administration is crucial for treatment efficacy.

Colonization of the gastrointestinal tract with multidrug-resistant (MDR) bacteria is a consequence of gut dysbiosis. We describe the successful utilization of fecal microbiota transplantation to inhibit Klebsiella pneumoniae MBL+ and Escherichia coli ESBL+ gut colonization in the immunocompromised host as a novel tool in the battle against MDR microorganisms.ClinicalTrials.gov identifier NCT02461199.

OBJECTIVE: To evaluate relatedness among methicillin-resistant Staphylococcus aureus (MRSA) strains isolated in Poland. METHODS: Ninety-three MRSA hospital isolates were collected from different regions in Poland from 1990 to 1992. Strains were analyzed with respect to heterogeneity of methicillin resistance, phage types, resistance patterns, crystal violet staining, chromosomal DNA SmaI restriction patterns by PFGE, ERIC1 and ERIC2 AP-PCR types and DNA repeat polymorphism within the protein A gene. Resistance to methicillin was confirmed by the detection of the mecA gene by PCR. RESULTS: The combined results of typing methods demonstrate that all MRSA strains analyzed could be easily divided into two distinct clones (clonally related strains). The first consisted of strains with clear heterogeneous expression of resistance to methicillin (34 isolates) and the second showed more homogeneous resistance (59 isolates). In this study the best method for epidemiologic analysis of MRSA was found to be PFGE. A good correlation between the epidemic behavior of MRSA and a high number of repetitive DNA units within the protein A gene was observed. CONCLUSIONS: Results show that in Poland two distinct clones of epidemic MRSA have circulated in the past, easily discriminated by pheno- and genotyping methods, and both could be found together in a single hospital.
