Mixed anaerobic infection

The symbiotic relationship between the normal anaerobic flora and aerobic flora of non-producing spores with mixed anaerobic infection index amount of about 100 is destroyed (such as surgery or other trauma, poor blood supply or tissue necrosis), among which Certain species of bacteria can cause infections with high morbidity and mortality, which can spread to the distance with the bloodstream after entering the body through these pathways. Because aerobic and anaerobic bacteria can often be found at the same site of infection, infections may be mixed, and anaerobic bacteria may be ignored unless they are isolated and cultured by appropriate methods. However, anaerobic bacteria may be the main pathogens of pleural cavity and lung, intraperitoneal cavity, gynecology, central nervous system, upper respiratory tract infections and skin diseases and bacteremia. Mixed infection rate of anaerobic and aerobic bacteria is as high as 82%
