Studies on natural gastric flora. I. Bacterial flora of fasting human subjects

摘要: Abstract The presence and survival of ingested micro-organisms, both pathogenic commensal, is practical interest because the stomach one principal portals entry bacteria in humans. A study environmental factors governing indigenous flora gastric lumen will assist determining whether potentially organisms survive pass on. The authors set out to determine significance mucin such survival, with ultimate objective learning what provide optimal bactericidal conditions. Samples juice were aspirated from 149 fasting individuals; samples saliva, nose throat swabs also obtained. Positive cultures found 82%. effects pH demonstrated an increase number showing growth above 2.0 a concomitant total bacterial growth. At lower than 2.0, certain are selected out. It appears that even minor changes gastrointestinal physiology disrupt normal clearing flora.
