Auswirkungen eines neuen Wassersystems auf nosokomiale Kolonisierung oder Infektion mit Pseudomonas aeruginosa
2016
Aim: We aimed to study the impact of new water systems, which were less contaminated with P. aeruginosa, on the incidence of healthcare-associated P. aeruginosa cases (colonizations or infections) in care units that moved to a different building between 2005 and 2014. Methods: Generalized Estimated Equations were used to compare the incidence of P. aeruginosa healthcare-associated cases according to the building. Results: Twenty-nine units moved during the study period and 2,759 cases occurred in these units. No difference was observed when the new building was compared with older buildings overall. Conclusion: Our results did not support our hypothesis of a positive association between wat…
Phenotypic and genetic analysis of biofilm formation by Staphylococcus epidermidis.
2012
Objective. The most important virulence factor of Staphylococcus epidermidis is their capability to form a biofilm on the surfaces of implanted medical devices. The accumulative phase of biofilm formation is linked to the production of intercellular adhesin encoded by the icaADBC operon and accumulation-associated protein by the aap gene. The aim of the study was to investigate biofilm formation phenotypically and genetically in clinical strains of S. epidermidis in comparison with commensal strains. Material and Methods. The study was carried out in 4 hospitals in Riga, Latvia. In total, 105 clinical strains of Staphylococcus epidermidis isolated from patients’ blood (n=67) and intravenous…
ESBL-producing Klebsiella pneumoniae in a University hospital: Molecular features, diffusion of epidemic clones and evaluation of cross-transmission.
2021
The worldwide spread of Klebsiella pneumoniae producing extended-spectrum β-lactamase (ESBL-Kp) is a significant threat. Specifically, various pandemic clones of ESBL-Kp are involved in hospital outbreaks and caused serious infections. In that context, we assessed the phenotypic and molecular features of a collection of ESBL-Kp isolates in a French university hospital and evaluated the occurrence of potential cross-transmissions. Over a 2-year period (2017–2018), 204 non-duplicate isolates of ESBL-Kp were isolated from clinical (n = 118, 57.8%) or screening (n = 86, 42.2%) sample cultures. These isolates were predominantly resistant to cotrimoxazole (88.8%) and ofloxacin (82.8%) but remaine…
Trend of MDR-microorganisms isolated from the biological samples of patients with HAI and from the surfaces around that patient.
2018
Healthcare-associated infections (HAI) continue to be a major public health concern. A number of epidemiologically relevant HAI microorganisms are multidrug-resistant (MDR) germs that can spread rapidly and/or carry multiple resistance to antibiotics. They are the cause of high mortality and possible nosocomial epidemics. For this reason, we implemented microbiological surveillance acquiring samples from patients with HAI and environmental samples from the surfaces surrounding those patients. A retrospective study was carried out from January 2014 to December 2016 in two departments of the University Hospital in Messina, Italy: the Microbiology and the Hygiene Laboratories. A comparison was…
Methicillin-resistant Staphylococcus aureus colonization: a three-year prospective study in a neonatal intensive care unit in Italy.
2014
Background: Methicillin resistant Staphylococcus aureus (MRSA) is a major etiological agent of infection in neonatal intensive care units (NICUs). Routes of entry of this organism can be different and the transmission pathway complex. Colonized neonates are the main endogenous reservoir. Methods and Results: We conducted a prospective three-year study on MRSA colonization recruiting 722 neonates admitted between 2009 and 2012. Nasal swabs were cultured weekly and MRSA isolates were submitted to molecular typing. The annual incidence density of acquisition of MRSA ranged from a maximum of 20.2 cases for 1000 patient-days during the first year to a minimum of 8.8 cases in the second one to ra…
Neonatal sepsis caused by Ralstonia pickettii
2008
e describe the clinical case of apremature newborn, born at 26weeks by cesarean delivery, followed inthe neonatal intensive care unit. Themother was diabetic with adequate con-trol during pregnancy.Neonatal weight was 930 g;APGAR score 3 at 1 minute and 8 at 5minutes. She received forced ventilationby endotracheal tube and parenteralnutrition by a central venous catheter.She was treated with ampicillin for thefirst 20 days of life. At 25 days, apneaand bradychardia episodes occurredwith a progressive increment in sever-ity and frequency. Leukocytes, C-re-active protein, cerebral echography,and echocardiogram were normal.Oralfeeding was transiently stopped and rani-tidine treatment was starte…
Assessment of the impact of inpatient infectious events in pediatric patients with newly diagnosed acute leukemia at Dr. Robert Reid Cabral Children’…
2020
Survival rates for pediatric acute leukemia vary dramatically worldwide. Infections are a leading cause of morbidity and mortality, and the impact is amplified in low and middle-income countries. Defining the epidemiology of infection in a specific health care setting is paramount to developing effective interventions. This study aimed to define the epidemiology of and outcomes from infection in children with acute leukemia treated in a large public pediatric hospital in the Dominican Republic. A retrospective cohort was assembled of children newly diagnosed with acute leukemia between July 1, 2015 to June 30, 2017 at Hospital Infantil Dr. Robert Reid Cabral in Santo Domingo. Patients were …
Detection of Temporal Clusters of Healthcare-Associated Infections or Colonizations with Pseudomonas aeruginosa in Two Hospitals: Comparison of SaTSc…
2014
International audience; The identification of temporal clusters of healthcare-associated colonizations or infections is a challenge in infection control. WHONET software is available to achieve these objectives using laboratory databases of hospitals but it has never been compared with SaTScan regarding its detection performance. This study provided the opportunity to evaluate the performance of WHONET software in comparison with SaTScan software as a reference to detect clusters of Pseudomonas aeruginosa. A retrospective study was conducted in two French university hospitals. Cases of P. aeruginosa colonizations or infections occurring between 1st January 2005 and 30th April 2014 in the fi…
Prevention of nosocomial infections and surveillance of emerging resistances in NICU
2011
Neonates hospitalized in NICU are at risk for healthcare associated infections because of their poor immune defenses, related to gestational age, colonization of mucous membranes and skin with nosocomial microorganisms, exposure to antibiotics, invasive procedures and frequent contacts with healthcare workers (HCWs). Healthcare associated infections are the major source of morbidity and mortality in NICU in the developed world. Most infections are caused by Gram-positive organisms, fulminant sepsis are often associated to Gram-negative organisms, fungal sepsis occurs frequently in ELBW infants. Hand hygiene is the most important preventive procedure, nevertheless hand hygiene compliance amo…
Development of a modified DNA extraction method for pulsed-field gel electrophoresis analysis of Staphylococcus aureus and enterococci without using …
2010
A modified pulsed-field gel electrophoresis (PFGE) protocol was developed and applied to clinical isolates of Staphylococcus aureus and enterococci to reduce the cost of using lysostaphin. This protocol reduces the expenses of PFGE typing of S. aureus and enterococci as it removes the use of lysostaphin during the spheroplast formation from these bacteria.
