Multiple causes of lung infection, multiple causes of lung infection is caused by what

multiple lung infection is caused by what the?

(a) causes

multiple lung infections can be any pathogen spectrum of different types of pathogens, or the same type in different species (species) infected with both pathogens, the more common pathogen combinations:

1. complex of two or more aerobic bacteria (including Gram-positive and gram-negative and two Gram-negative bacilli or both Gram-positive bacteria), aerobic and anaerobic bacteria, sub- branch bacterial infection with ordinary bacteria.

2. bacterial plus fungal infection of any bacterial and fungal infection, the aerobic bacteria and opportunistic pathogens such as Candida, Aspergillus the most common.

3. protozoa increases bacterial infection in insects Pneumocystis carinii is a common bacterial infection.

4. common respiratory viral infection plus bacterial infection secondary bacterial infection, immune suppression in patients with common bacteria and cytomegalovirus infection.

(B) the pathogenesis

1. clinical disease spectrum of multiple infection is common in aspiration pneumonia and lung abscess, bronchiectasis, nosocomial pneumonia, especially ventilator-associated pneumonia, pneumonia and immune damage to host a variety of other severe pneumonia.

2. risk factors age, underlying diseases (chronic airway disease, diabetes, kidney failure, heart failure, etc.), disturbance of consciousness, alcoholism, malnutrition, immunosuppression, mechanical ventilation and other invasive treatment technologies (such as bronchoscopy), the initial antibiotic treatment, latent infection or infectious disease epidemic in some endemic foci of residence or special environmental exposure, with end-stage disease, especially long-term hospitalization of ICU stay and so can be the incidence of multiple lung infection risk factor.
