Assessing microbial colonization of peripheral intravascular devices.

Microbial colonization of endotracheal tube in intensive care unit patients

Microbial biofilms has remained a major complication of tracheal intubation in patients requiring ventilator equipment. The aim of this study was to characterize bacterial and fungal biofilms in endotracheal tubes from intensive care unit (ICU) patients in Ahwaz, Iran. In this cross-sectional descriptive study, patients admitted to ICU that required mechanical ventilation for at least 24 hours ...

Microbial colonization of human ileal conduits.

Morphological and microbiological techniques were used to locate and identify the microorganisms that colonized the human ileal conduits in 17 different patients from 5 days after surgery up to as many as 16 years of service as a urine conduit. The ecological sequence of this colonization assumes some practical importance because the ascending growth of pathogenic organisms in this essentially ...

Micromechanical devices for intravascular drug delivery.

Microfabrication technology, more commonly applied to the manufacture of integrated circuits, can be used to build devices useful for mechanical delivery of drugs and genes. Microprobes fabricated using silicon micromachining have been used to deliver DNA into cells as an alternative to bombardment and microinjection. This idea can be extended to intravascular stents with integrated microprobes...

Colonization-Induced Host-Gut Microbial Metabolic Interaction

UNLABELLED The gut microbiota enhances the host's metabolic capacity for processing nutrients and drugs and modulate the activities of multiple pathways in a variety of organ systems. We have probed the systemic metabolic adaptation to gut colonization for 20 days following exposure of axenic mice (n = 35) to a typical environmental microbial background using high-resolution (1)H nuclear magnet...
