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.
Many of these infections are less serious, but the Centers for Disease Control and Prevention (CDC) estimate that there are 80,461 invasive MRSA infections and 11,285 deaths due to MRSA annually. [109] In 2003, the cost for a hospitalization due to MRSA infection was US$92,363; a hospital stay for MSSA was $52,791. [89]
First-line treatment for serious invasive infections due to MRSA is currently glycopeptide antibiotics (vancomycin and teicoplanin). A number of problems with these antibiotics occur, such as the need for intravenous administration (no oral preparation is available), toxicity, and the need to monitor drug levels regularly by blood tests.
Problematically, methicillin-resistant Staphylococcus aureus (MRSA) has become a major cause of hospital-acquired infections. MRSA has also been recognized with increasing frequency in community-acquired infections. [7] The symptoms of a staphylococcal infection include a collection of pus, such as a boil or furuncle, or abscess.
[12] [14] Pneumonia is also the leading cause of death in children less than five years of age in low income countries. [14] The most common cause of pneumonia is pneumococcal bacteria, Streptococcus pneumoniae accounts for 2/3 of bacteremic pneumonias. [15] Invasive pneumococcal pneumonia has a mortality rate of around 20%. [13]
Lung abscesses can usually be seen with a chest X-ray but frequently require a chest CT scan to confirm the diagnosis. [141] Abscesses typically occur in aspiration pneumonia, and often contain several types of bacteria. Long-term antibiotics are usually adequate to treat a lung abscess, but sometimes the abscess must be drained by a surgeon or ...
The more invasive methicillin-resistant Staphylococcus aureus (MRSA) may also be a source of infection, though is much rarer. [22] Among spinal subdural abscesses, methicillin-sensitive Staphylococcus aureus is the most common organism involved. [21] Rarely parasites can cause abscesses and this is more common in the developing world. [3]
Peptostreptococcus can cause brain, liver, breast, and lung abscesses, as well as generalized necrotizing soft tissue infections. They participate in mixed anaerobic infections , a term which is used to describe infections that are caused by multiple bacteria that do not require or may even be harmed by oxygen.
