324 kHz -327 kHz Bacteroides fragilis:
Infectivity category: 2.
This bacteria can cause necrotizing inflammation such as gingivitis, which can also lead to autoimmune gum atrophy.
As an anaerobic bacterium the Bacteroides fragilis causes inflammation and necrosis, in which the blood circulation and the oxygen supply to the tissue are poor, for example in damaged tissues.
The toxins of these bacteria promote susceptibility to allergies, are involved in the development of allergies and can therefore play a role in the development of asthma.
