The epidemiological landscape of bloodstream infections in children undergoing chemotherapy or haematopoietic cell transplantation: A retrospective study by Infectious Diseases Working Group of Italian Association of Pediatric Hematology and Oncology (AIEOP)

British Journal of Haematology, EarlyView.
Summary Understanding bloodstream infection (BSI) epidemiology is crucial for optimizing antibiotic therapy in paediatric haematology–oncology patients undergoing chemotherapy or haematopoietic cell transplantation (HCT). However, updated paediatric data remain scarce.

Attachment ofStreptococcus oralison acrylic substrates of varying roughness [PDF]

Letters in Applied Microbiology, 2009
To determine the effect of the surface roughness of denture acrylic on the attachment of Streptococcus oralis.Roughened denture acrylic samples were assessed for bacterial attachment, over time, using microscopy. The area of the image covered by bacteria was calculated and converted into a percentage of the total area sampled.
