C. pneumoniae infection may not only be persistent and chronic, but it also has irreversible tissue injury and scarring processes, [2] which are symptoms in asthma patients. Infection with C. pneumoniae induces both humoral and cell-mediated immune responses. [2]
Three stages can be used to categorize the infection process of pneumococcal pneumonia: transmission, colonization, and invasion. [5] The Streptococcus pneumoniae ( S. pneumoniae ) leave the colonized host via shedding in order to be transmissible to new hosts, and must survive in the environment until infection of a new host (unless direct ...
A pulmonary hematoma is a collection of blood within the tissue of the lung. It may result when a pulmonary laceration fills with blood. [1] A lung laceration filled with air is called a pneumatocele. [1] In some cases, both pneumatoceles and hematomas exist in the same injured lung. [2]
Some patients have an underlying problem which increases their risk of infection. Some risk factors are: Obstruction - When part of the airway leading to the alveoli is obstructed, the lung cannot eliminate fluid; this can lead to pneumonia. One cause of obstruction, especially in young children, is inhalation of a foreign object such as a ...
Side effects on the lungs can be very varied, and can include signs and symptoms that are either clinical, or radiological (i.e., seen on chest X-ray or CT), or both.They can include lung inflammation (pneumonitis), secondary (in this context, indirectly caused) lung infection (), lung fibrosis, organising pneumonia (bronchiolitis obliterans organising pneumonia, BOOP), ARDS (acute respiratory ...
Lung abscess is a type of liquefactive necrosis of the lung tissue and formation of cavities (more than 2 cm) [1] containing necrotic debris or fluid caused by microbial infection. This pus -filled cavity is often caused by aspiration, which may occur during anesthesia, sedation, or unconsciousness from injury.
Patients that are immunodeficient and don't get treated immediately for any type of respiratory infection may lead to more severe infections and/or death. [ 6 ] Pneumonitis can be classified into several different specific subcategories, including hypersensitivity pneumonitis , radiation pneumonitis , acute interstitial pneumonitis , and ...
Chlamydia pneumoniae [1] is a species of Chlamydia, an obligate intracellular bacterium [2] that infects humans and is a major cause of pneumonia.It was known as the Taiwan acute respiratory agent (TWAR) from the names of the two original isolates – Taiwan (TW-183) and an acute respiratory isolate designated AR-39.
