Cluster of cases due to Shigella flexneri producing CTX-M-15 in Spain.

The aim of our study was to delineate an outbreak of gastroenteritis caused by Shigella flexneri and affecting sixteen persons between May and June 2014 in Bilbao, Spain. All patients exhibited symptoms after consuming kebab in the same kebab shop.The outbreak is described through the clinical cases, the microbiological and molecular genetic diagnosis, and the epidemiologic investigation.

Összefoglaló. A cardiovascularis megbetegedések kialakulását és progresszióját jelentősen befolyásolja az életmód, ezen belül a fizikai aktivitás. A rendszeres testmozgás csökkenti a szív- és érrendszeri kórképek kockázatát, többek között a magas vérnyomásra, a zsíranyagcsere-eltérésekre és az elhízásra gyakorolt kedvező hatásán keresztül, továbbá független tényező a cardiovascularis halálozás szempontjából is.

Natural radioactivity and radiological risks of common building materials used in Semnan Province dwellings, Iran.

Impact assessment of building materials is a focused topic in the field of radioecology. A radiological survey has conducted to monitor radioactivity of most common building materials in Semnan Province, Iran, and assess the radiation risk. Activity concentrations of Ra, Th, and K were measured in 29 samples including nine commonly used building materials that were collected from local suppliers and manufacturers, using a high purity germanium gamma-ray detector.

Transfer of radionuclides from soil to Acacia auriculiformis trees in high radioactive background areas in North Vietnam.

The Acacia auriculiformis is a tree common in tropical Asian countries, capable of growing in many different soil types, so it could be used for biomonitoring for high natural radionuclide areas in tropical and subtropical climates. The transfer factor (TF) of radionuclides from soil to A. auriculiformis in eight uranium and rare earth element (REE) mining areas of North Vietnam was investigated.

Study of Well Waters from High-Level Natural Radiation Areas in Northern Vietnam.

The determination of natural radionuclide concentrations plays an important role for assuring public health and in the estimation of the radiological hazards. This is especially true for high level radiation areas. In this study, Ra, Ra and U concentrations were measured in well waters surrounding eight of the high-level natural radiation areas in northern Vietnam.

blaNDM-1 Carriage on IncR Plasmid in Enterobacteriaceae Strains.

Four NDM-1-producing Enterobacteriaceae strains (three Klebsiella pneumoniae and one Citrobacter koseri) were isolated between 2009 and 2011 through a nationwide surveillance for carbapenem-resistant Enterobacteriaceae in Croatia to study the molecular genetic background of blaNDM and the responsible plasmid types. Phenotypically, the clinical strains proved to be multidrug resistant. All strains remained susceptible to tigecycline and colistin.

KPC-3 carbapenemase harbored in FIIk plasmid from Klebsiella pneumoniae ST512 and Escherichia coli ST43 in the same patient.

Five carbapenem-resistant strains (three Klebsiella pneumoniae, one Escherichia coli, and one Enterobacter aerogenes) were isolated between 2009 and 2012 at the Verona University Hospital, Italy, during an epidemiological analysis of antibiotic resistance determinants and plasmid profiles in Enterobacteriaceae. Two out of the five strains, K. pneumoniae E530 and E.

Identification of blaLAP-₂ and qnrS1 genes in the internationally successful Klebsiella pneumoniae ST147 clone.

We investigated the presence of β-lactamase genes (bla) in 26 strains of Enterobacteriaceae already found positive for the qnrS1 gene, a plasmid-mediated quinolone resistance determinant. Three strains of K. pneumoniae, isolated in the period 2008-2009 at the University Hospital in Verona, were positive for LAP-2, a narrow-spectrum β-lactamase.

Co-infection by two linezolid-resistant coagulase-negative staphylococci with two different resistance determinants.

Linezolid resistance among Gram-positive pathogens is being reported with increasing frequency. We examined 14 linezolid-resistant coagulase-negative staphylococci (CoNS) isolated from blood cultures obtained from patients admitted to the Intensive Care Unit of Vicenza General Hospital, Italy. The species identification yielded 10 Staphylococcus epidermidis, 3 Staphylococcus hominis, and 1 Staphylococcus capitis.

Role of direct bioautographic method for detection of antistaphylococcal activity of essential oils.

The aim of the present study was the chemical characterization of some traditionally used and therapeutically relevant essential oils (thyme, eucalyptus, cinnamon bark, clove, and tea tree) and the optimized microbiological investigation of the effect of these oils on clinical isolates of methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-susceptible S. aureus (MSSA). The chemical composition of the oils was analyzed by TLC, and controlled by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS).

Design, synthesis and determination of antifungal activity of 5(6)-substituted benzotriazoles.

In an effort to find inhibitors that are effective against both Candida and Aspergillus spp., a series of 5(6)-(un)substituted benzotriazole analogs, represented by compounds 3a-3h and 3b'-3f', were prepared using a crystalline oxirane intermediate 1 previously synthesized in our laboratory. All the compounds were evaluated for inhibitory activity against various species of Candida and Aspergillus.

Clinical microbiology of early-onset and late-onset neonatal sepsis, particularly among preterm babies.

Prematurity has got special challenge for clinicians and also other medical staff, such as microbiologists. Immature host defense mechanisms support early-onset sepsis, which can be very serious with very high mortality. While the past decade has been marked by a significant decline in early-onset group B streptococcal (GBS) sepsis in both term and preterm neonates, the overall incidence of early-onset sepsis has not decreased in many centers, and several studies have found an increase in sepsis due to gram-negative organisms.

Comparison of Austrian, Hungarian and Macedonian methicillin-resistant and methicillin-sensitive Staphylococcus aureus strains in relation to prevalence of cytotoxin genes.

Cytotoxin genes in 128 Austrian (AT) MSSA, 48 MRSA, 94 Hungarian (HU) MSSA, 110 MRSA and 67 Macedonian (MK) MSSA, 81 MRSA strains were examined. The presence of alfa-haemolysin gene (hla) was more common in HU MSSA strains compared to AT and MK (99%, 86%, 72%: p<0.001).
