The investigation of an outbreak of Pseudomonas aeruginosa urinary tract infections after ambulatory cystoscopies identified a damaged cystoscope contaminated by P aeruginosa and acting as a relay object. This outbreak urges us not to trivialize urinary tract infections occurring after an elective cystoscopy. Patients should be advised to signal the occurrence of urologic symptoms after urologic exploration.

ESBL-KP strains isolated from patients and environment were compared by molecular typing. The density of incidence of multi-drug-resistant bacteria (MDRB) was calculated from January 2014 to September 2016.

Through 2 emblematic cases of in-hospital transmission of extensively drug-resistant bacteria producing carbapenemases, we demonstrate the impact of colony sampling in typing results. Because of intra-population diversity, typing several colonies of same species and resistotype was needed to fully track the transmission among patients.

We aimed to determine the CVC maintenance-related complications at this site compared to the others (i.e.

Despite many advantages, PICC-related complications can occur such as infection, thrombosis or mechanical complications. We aimed to evaluate rates and nature of PICC-related complications from insertion to removal and analyze risk factors of complications at baseline and during healthcare.

In this study, we investigate epidemiological links between apparently unrelated cases of OXA-48-producing Klebsiella pneumoniae (Kp OXA-48) colonisation or infection. We genotyped detected organisms by repetitive sequence-based PCR, and used a dynamic registry of cases and contacts to cross-reference patients' hospital stays.

Due to the predilection toward a wet environment, strong adhesion, biofilm formation, and resistance to biocides, Pseudomonas aeruginosa, a major human opportunistic pathogen, is adapted to DCUW colonization. Other nonfermentative Gram-negative bacilli, such as members of the genus Achromobacter, are emerging pathogens found in water networks.

A role of microbiota disequilibrium in infection occurrence is hypothesized, particularly in surgical site infections. We study the diversities of operative site microbiota and its dynamics during surgical pathway of patients undergoing coronary-artery by-pass graft (CABG).

Background: In the context of a methicillin-susceptible Staphylococcus aureus (MSSA) outbreak, we aimed to improve our knowledge of S. aureus (SA) epidemiology in the neonatal care center (NCC) of a tertiary care teaching hospital.
Methods: We performed a complete one-year review of SA carrier, colonized or infected patients.
We report the observation of a necrotizing pneumonia due to methicillin-resistant Staphylococcus aureus harboring the Panton-Valentine leukocidin-encoding gene in a previously healthy neonate, with favorable clinical outcome in spite of extensive radiologic lesions. The case was linked to a cluster of 3 neonates colonized by Panton-Valentine leukocidin-producing, methicillin-resistant S. aureus through cross-transmission in the nursery, underlining the need to comply with standard infection control precautions in the maternity ward.

We investigated the role of hospital hygiene in the transmission and eradication of an h-GISA outbreak.

Antiseptic and topical antimicrobial compounds constitute major resources for burns care but in vitro testing of their activity is not performed in practice.
Results: In our burn unit, a P.
We describe what we believe to be the first documented case of Mycobacterium goodii infection in Europe. It is also the second documented report of a pacemaker pocket surgical site infection caused by M. goodii.

Objective: To evaluate the impact of an infection control program in an intensive care unit (ICU).
Design: Prospective before-after study. Two 6-month study periods were compared; between these periods, an infection control program based on isolation was implemented.
Between January and April 2003, a sudden increase in positive respiratory tract specimens for Pseudomonas aeruginosa was observed in an intensive care unit of the University Teaching Hospital of Montpellier, France. Most of the strains were cultured from bronchoalveolar lavage fluid samples, suggesting that bronchoscopic procedures could be implicated. The relationships between isolates were investigated by antibiotyping and pulsed-field gel electrophoresis.
