Final answer:
Atypical Pneumonia involves infection of the alveolar septum or interstitium by viral and mycoplasma organisms, presenting with diffuse lung involvement and milder symptoms compared to bacterial pneumonia.
Step-by-step explanation:
The type of pneumonia characterized by viral and mycoplasma infections of the alveolar septum or interstitium is known as Atypical Pneumonia. This form of pneumonia is different from the typical bacterial pneumonia because it doesn't affect the alveoli directly. Instead, the infection is more spread throughout the interstitium, which is the tissue and space around the air sacs of the lungs, causing a more diffuse pattern of lung involvement.
Atypical Pneumonia is caused by various pathogens, including viral agents like influenza and adenoviruses, and bacteria such as Mycoplasma pneumoniae. The symptoms can be milder than those of typical bacterial pneumonia and can include a dry cough, headache, and fever. It often requires a different treatment approach, usually with antibiotics effective against Mycoplasma pneumoniae and supportive care for viral infections.
Atypical Pneumonia is associated with viral and mycoplasma infections of the alveolar septum or interstitium. It presents with diffuse lung involvement that doesn't necessarily abide by the typical symptoms and patterns seen in bacterial pneumonia.
