Asymptomatic carriage and molecular characterization of Staphylococcus aureus in pre-clinical and clinical medical students.
Folia Microbiol (Praha)
January 2025
Department of Public Health, Faculty of Medicine, Masaryk University, Kamenice 753/5, 625 00, Brno, Czech Republic.
Medical students are exposed to the hospital environment and patients during their studies, increasing the risk of exposure to virulent and antibiotic-resistant isolates of Staphylococcus aureus. The aim of the study is to determine the prevalence of Staphylococcus aureus among medical students who have varying levels of exposure to the hospital environment to provide valuable insights into the risk of colonization and transmission. Nasal swabs and fingerprints were obtained and cultured on a selective medium for staphylococci.

Neonatal sepsis, a severe infection in newborns, remains one of the leading causes of morbidity and mortality among preterm infants. This study aimed to investigate the distribution of pathogens responsible for early-onset sepsis (EOS) and late-onset sepsis (LOS), the annual variability of pathogens responsible for each type of infection, and potential trends in their profiles in preterm infants from a tertiary care neonatal intensive care unit over a ten-year period. We analyzed 177 episodes of confirmed bloodstream infection between 1 January 2014 and 31 December 2023.

This study aims to validate sanitation standard operating procedures (SSOP) of the pre-cooling system in two immersion stages with different temperatures followed by dripping for 3 minutes. The variables evaluated were temperature, weight, microbiological quality, and safety of chicken carcasses. Groups of indicator microorganisms were quantified and the occurrence of Salmonella spp.

Introduction: Open repair of Congenital diaphragmatic hernia (CDH) in neonates often involves reconstruction of the abdominal wall using a patch. Data on predictors for the need of a patch and associated postoperative risks, such as infection or patch detachment, are limited. Specifically, the question regarding the ideal timepoint of patch removal remains unanswered.

Finding effective antibiotics against multi-resistant strains of bacteria has been a challenging race. Linker-Evolved-Group-Optimized-Lipophosphonoxins (LEGO-LPPOs) are small modular synthetic antibacterial compounds targeting the cytoplasmic membrane. Here we focused on understanding the reasons for the variable efficacy of selected LEGO-LPPOs (LEGO-1, LEGO-2, LEGO-3, and LEGO-4) differing in hydrophobic and linker module structure and length.
