Haemophili in faeces.

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.
