Using Multi-fluorinated Bile Acids and In Vivo Magnetic Resonance Imaging to Measure Bile Acid Transport
Published on: November 27, 2016
Abstract:
By plating faeces on a selective medium, haemophili were isolated from 26% of 612 samples from patients of all ages and 12% of 525 samples from apparently healthy meatworkers. Most isolates were Haemophilus parainfluenzae. Only specimens received for laboratory investigation for pathogens were examined in this study; the faecal carriage of haemophili in healthy persons is not known.
Insights
Haemophilus bacteria were found in the feces of 26% of patients and 12% of healthy meatworkers. Most isolates were Haemophilus parainfluenzae, but fecal carriage in the general population remains unknown.
Area of Science:
- Microbiology
- Bacteriology
Background:
- Haemophilus species are known human commensals and pathogens.
- The presence and prevalence of Haemophilus in human feces are not well-documented.
Purpose of the Study:
- To investigate the prevalence of Haemophilus in fecal samples from patients and healthy meatworkers.
- To identify the predominant Haemophilus species found in fecal carriage.
Main Methods:
- Fecal samples were collected from 612 patients and 525 healthy meatworkers.
- Samples were plated on a selective medium for the isolation of Haemophilus.
- Isolates were identified to the species level.
Main Results:
- Haemophilus was isolated from 26% of patient fecal samples.
- Haemophilus was isolated from 12% of healthy meatworker fecal samples.
- The majority of isolates were identified as Haemophilus parainfluenzae.
Conclusions:
- Haemophilus species, particularly Haemophilus parainfluenzae, are present in human feces.
- Fecal carriage of Haemophilus is detectable in both patient and healthy populations.
- Further studies are needed to determine the fecal carriage rate in the general healthy population.

Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which forms a...
