Hello, my name is Walter Spectre, I am one of the adjunct professors of the department, and on this occasion we are going to talk about community-acquired pneumonia.

As you know, acute community-acquired pneumonia is defined as pneumonia, that is, an acute infection of the lung parenchyma. The second condition that must be present for it to be considered acute community-acquired pneumonia is, obviously, that it be acquired in the community. Community-acquired pneumonia is defined as people who, without prior hospitalization ( 14 days prior to the onset of symptoms) or

currently, are not experiencing the onset of symptoms after two days, or who are hospitalized. When we define the causes, let's say [Music], regarding the etiology of acute community-acquired pneumonia in adult patients, as we can see in this graph, the three main bacterial causes are represented by pneumococcus, that is, Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella

catarrhalis. And if we look at this graph... And also in our country and in the rest of the regions something similar happens. The next germs, which are mycoplasma pneumoniae, chlamydia pneumoniae, and legionella, were what were formerly called atypical pneumonias, a term that no longer depends on these germs for this classification because, given the limited

possibility of predicting the etiological agent based on clinical findings, as it was formerly considered atypical because there was a clinical- radiological dissociation, it was made up of these three main germs, and typical, which was a relationship between the clinical and radiological findings, was made up of the other three germs. Today it is not
