Candidemia in cancer patients: features of the taxonomic structure.

The aim of the study was to determine the main Candida species isolated from blood of cancer patients, to compare the taxonomic structure of strains obtained from children and adults with candidemia. In total, during the study period, candidemia was microbiologically proven by blood culture in 81 patients (duplicates were excluded). Patients in the intensive care unit (ICU) accounted for 35,8%.

Microbiological and molecular identification of the anaerobic component of the oral microbiota in patients with cancer of the oropharyngeal region.

A research objective - to study tumor tissues of primary and recurrent patients with cancer of the oropharyngeal region for the frequency of occurrence of four types of anaerobic periodontogens and their associations by two methods: real-time PCR and cultural. There is speculation that bacteria can influence the pathogenesis of cancer. A comparative assessment of the content of four anaerobic periodontogens (Porphyromonas gingivalis, Prevotella intermedia, Tannerella forsythensis, Treponema denticola) in the tumor tissue and in the healthy tissue of the oral mucosa of patients with oropharyngeal cancer was carried out.

Global Expansion of Linezolid-Resistant Coagulase-Negative Staphylococci.

Coagulase-negative staphylococci (CoNS) for a long time were considered avirulent constituents of the human and warm-blooded animal microbiota. However, at present, , , and are recognized as opportunistic pathogens. Although linezolid is not registered for the treatment of CoNS infections, it is widely used off-label, promoting emergence of resistance.
