Bacterial viability in dry-surface biofilms in healthcare facilities: a systematic review.

Background: Bacteria are known to live inside architectural structures called biofilms. Though standard biofilms have been studied extensively for more than 50 years, little is known about dry-surface biofilms (DSBs). Since 2012, DSBs have been described in several scientific papers, but basic knowledge about the viability and culturability of bacteria remains limited.

A new spray-based method for the in-vitro development of dry-surface biofilms.

The inanimate environment immediately surrounding the patient in healthcare facilities is a reservoir of microorganisms embedded in dry-surface biofilms (DSB). These biofilms, first highlighted in 2012, are increasingly studied, but currently available in-vitro models only allow for the growth of semi-hydrated biofilms. We developed a new in-vitro method under actual dehydration conditions based on the hypothesis that surface contamination is mainly due to splashes of respiratory secretions.

spp. Surgical Site Infections: A Systematic Review of Case Reports and Case Series.

species are isolated from rare but severe healthcare-associated infections, including surgical site infections. They are considered to preferentially infect immunocompromised patients but so far with limited evidence. We conducted a systematic review on spp.

Achromobacter xylosoxidans in hospital environments: still waters run deep!

Background: Hospital reservoirs of Achromobacter xylosoxidans, responsible for nosocomial infections, are poorly known.

Methods: We examined the growth, survival and biofilm formation of five A. xylosoxidans strains for up to 2 y in distilled, dialysis or microfiltered water.

Achromobacter spp. healthcare associated infections in the French West Indies: a longitudinal study from 2006 to 2016.

Background: Bacteria of the Achromobacter genus, more particularly xylosoxidans species, are responsible for various healthcare associated infections (HAI) which are increasingly described since the last decade. Cystic fibrosis (CF) patients are considered as potential reservoirs in hospitals. We performed a retrospective study to estimate the frequencies of Achromobacter spp.
