Comparative Genome Analysis of Hungarian and Global Strains of Infantis.

Introduction: The emergence and spread of new strains of zoonotic bacteria, such as multidrug resistant (MDR) Infantis, represent a growing health risk for humans in and outside Europe due to foodborne infections of poultry meat origin.

Objectives: In order to understand genome relations of . Infantis strains from Hungary and from different geographic regions, we performed a comprehensive genome analysis of nine Hungarian and 67 globally selected strains of .

Groundwater, soil and compost, as possible sources of virulent and antibiotic-resistant Pseudomonas aeruginosa.

is a major public health concern all around the world. In the frame of this work, a set of diverse environmental isolates with various antibiotic resistance profiles were examined in a virulence model. Motility, serotypes, virulence factors and biofilm-forming ability were also examined.

An international outbreak of Salmonella enterica serotype Enteritidis linked to eggs from Poland: a microbiological and epidemiological study.

Background: Salmonella spp are a major cause of food-borne outbreaks in Europe. We investigated a large multi-country outbreak of Salmonella enterica serotype Enteritidis in the EU and European Economic Area (EEA).

Methods: A confirmed case was defined as a laboratory-confirmed infection with the outbreak strains of S Enteritidis based on whole-genome sequencing (WGS), occurring between May 1, 2015, and Oct 31, 2018.

Characterization of Clinical Vancomycin-Resistant Enterococcus faecium Isolated in Eastern Hungary.

Objectives: The aim of our study was to characterize and elicit the genetic relatedness of emerging vancomycin-resistant enterococci (VRE) isolated between 2012 and 2015 at a teaching hospital in Debrecen, Hungary.

Results: Altogether 43 nonduplicate vancomycin-resistant Enterococcus faecium (VREfm) clinical isolates were obtained. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry was used for species identification.

Dissemination of VanA-Type Enterococcus faecium Isolates in Hungary.

Although vanA carrying Enterococcus faecium human clinical isolates have been rarely found in Hungary before 2012, they have been detected in continuously increasing numbers since then. To identify factors associated with their dissemination, we investigated the clonal relatedness and plasmids of 30 vanA carrying E. faecium isolates originating from different Hungarian healthcare institutions from 2012 to 2014.
