Hospitalised patients are at risk of_______________
resistant hospital-acquired bacteria
What part of the lung does lobar pneumonia affect?

What is the common culprit for lobar pneumonia? and who is at risk?
S. pneumoniae
Otherwise healthy young adults
What symptoms are associated with lobar pneumonia?
rigors, chills, high fever, pleurisy
Describe how bronchopneumonia looks like
Patchy distribution
Centred on inflamed bronchi and bronchioles with spread into surrounding alveoli
* Bronchi filled with pus and acute inflammation seen in bronchi and surrounding alveoli
Bacteria causing bronchopneumonia
S. pneumonia, H. influenza, S. aureus
T/F Lobar pneumonia is more common than bronchopneumonia
F
Problems with atypical bacteria
Don’t grow on routine laboratory media
* Don’t respond to beta-lactam antibiotics
* Can sometimes be associated with some unusual systemic features
Causes of atypical bacterial pneumonia (bacteria involved)
Mycoplasma pneumoniae
* Chlamydophila pneumoniae
* Chlamydophila psittaci
* Legionella pneumophila
Chlamydia psittaci is associated with what condition?
Parrot fever
Which bacteria is more dangerous and can cause outbrakes in both the community and hospitals?
Legionella pneumophila
Where is legionella pneumophila normally found?
In warm water systems
How does legionella pneumophila enter the human body?
Inhalation of contaminated aerosols causes disease
* e.g. showers, sprinklers, de-misters, cooling towers, jacuzzis,
