Tritium content in vegetation cover at nuclear test locations at the "Sary-Uzen" site in the Semipalatinsk Test Site.

Numerous areas of the Semipalatinsk Test Site (STS) were subjected to radioactive contamination, including tritium. The tritium content in plants was determined in free water (TFWT) and in the organic component (OBT). It has been established that the OBT content in plants for the "Sary-Uzen" site between combat boreholes ranges from <7-125 Bq/kg and the background OBT content is 21.

The Effect of Radionuclide and Chemical Contamination on Morphological and Anatomical Parameters of Plants.

This article presents the results of a study of the influence of radionuclide and chemical pollution on the morphological and anatomical parameters of plants growing in the territory of "Degelen" at the Semipalatinsk Test Site (STS). Quantitative data of morphological and anatomical parameters are given, and the content of radionuclides and toxic elements in samples of plants obtained. Statistical processing of the obtained data was conducted.

Artificial radionuclides in the plant cover around nuclear fuel cycle facilities.

This paper presents research on the assessment of the radioecological state of plant cover surrounding two research reactor facilities located within the Semipalatinsk Test Site (STS) as examples of nuclear fuel cycle facilities (NFC). Source data on the concentrations of artificial radionuclides in the plant cover were obtained. Quantitative values for 137Cs, 241Am, and 239+240Pu activity concentrations were determined in plants across the perimeters of the facilities, indicating that these compounds may be present in the associated media from the perspective of accumulative bioindication.

High Prevalence of Ribotype 176 in the University Hospital in Kosice.

Dysbiosis of the gut microbiota, caused by antibiotics, plays a key role in the establishment of CD). Toxin-producing strains are involved in the pathogenesis of infection (CDI), one of the most common hospital-acquired infections. We cultured a total of 84 isolates from stool samples of patients hospitalized at Louis Pasteur University Hospital in Kosice, Slovakia, that were suspected of CDI and further characterized by molecular methods.

Antibiotic resistance in the invasive bacteria Escherichia coli.

Objectives: The beta-lactamases with extended spectrum of activity (ESBL) are medically one of the most important group of enzymes. Another group of beta-lactamases representing of Enterobacteriaceae is group of the AmpC-type cephalosporinases. The presented study provides identification and determination of the spectrum of resistance against different and clinically used antimicrobial drugs in the clinical isolates of Escherichia coli.
