We studied the effects of in vitro and in vivo coating of catheters with human blood proteins on binding of coagulase-negative staphylococci. Coating resulted in no enhancement of binding. Catheters coated in vitro bound fewer organisms than uncoated catheters. Host proteins do not enhance adherence of coagulase-negative staphylococci to biomaterials.

Background: Periprosthetic joint infection (PJI) is a devastating complication following arthroplasty of the hip or knee joint and can be challenging to treat, depending on the underlying pathogen. There is still a debate whether streptococcal PJI are more difficult to treat than those caused by staphylococci. We aimed to investigate if the treatment results after PJI caused by (), spp.

Background: Mobile phones used by healthcare workers (HCWs) in hospitals are significant reservoirs of drug-resistant bacteria responsible for hospital-acquired infections (HAIs).
Aim: The objective of this study was to assess the level of contamination with such bacteria in outpatient clinics.
Methods: Swabs from 83 HCWs' mobile phones were processed using standard biochemical and enzymatic procedures to identify pathogenic bacteria.

Background: Surveillance cultures to identify patients colonized with methicillin-resistant Staphylococcus aureus (MRSA) is recommended at pediatric intensive care unit (PICU) admission but doesn't capture other methicillin-resistant Staphylococcus and is resource intensive. We determined the prevalence and identified nasal microbiome predictors for methicillin-resistant Staphylococcus colonization at the time of PICU admission.
Study Design: A prospective cohort study was performed in a 20-bed pediatric intensive care unit (PICU) between 2020-2021.
Introduction-Aim: Spontaneous bacterial peritonitis (SBP) is a common complication in cirrhotic patients and is associated with a high mortality rate. The aim of this study is to determine the epidemiological and bacteriological profile of spontaneous bacterial peritonitis, as well as antibiotic resistance among hospitalized patients at CHU Mohammed VI, in order to guide empirical antibiotic choices for better management. Methods: This is a prospective study conducted over a period of 12 months, from January to December 2023, focusing on all requests for bacteriological examination of ascitic fluid samples.

Introduction: Room air class (RC) Ib may be necessary for surgical procedures in aseptic working areas. The aim of the study was to examine whether a mobile, three-stage sterile ventilation unit (MSVU) can replace a room ventilation system (RVS) with turbulent mixed flow (TMF) in the area of the operating field and on the instrument table from hygienic-microbiological point of view.
Method: During 26 surgeries (varicose vein stripping or treatment of umbilical and inguinal hernias), the microbial load was recorded at 4 measuring points (M1-M4) during regular operations by setting up sedimentation plates and measuring the particle concentration.
