In other cases, these drugs may induce alterations in their normal intestinal flora, mainly through the acquisition of antibiotic-resistant and/or pathogenic bacteria [5], [6].
Compared to normal mice, mice without HIF-1 had 1000 times more bacteria in their body post-infection and developed skin legions that were twice as big, the team reports today in the Journal of Clinical Investigation.
Bacterial inocula were prepared by suspending the freshly grown bacteria in sterile normal saline and adjusted to a 0.5 McFarland standard.
Although anaerobic bacteria significantly outnumber other Gram-negative bacteria in the normal flora of the gastrointestinal (GI) tract, they have surprisingly weak pathogenicity as compared with other species [ 5].
Normal physiological events such as stress are associated with the onset of relapse in IBD patients and have been demonstrated to increase epithelial barrier permeability resulting in elevated levels of intracellular bacteria in normal animals [16],[16].
Figure 5 shows that the most abundant bacteria in normal samples were Bacteroides (27.7%), Prevotella (19.4%), Escherichia (12%), Phascolarctobacterium (3.9%), and Eubacterium (3.5%).
The supervised analysis showed that the most, abundant genera of bacteria in normal samples (from people with a body mass index (BMI) ≤ 24) were Bacteroides (27.7%), Prevotella (19.4%), Escherichia (12%), Phascolarctobacterium (3.9%), and Eubacterium (3.5%).
The MFCs are full of specially-grown bacteria that break down the chemicals in urine as part of their normal metabolic process.
