Case Study 1
A 64-year old male with fever, malaise, and cough.
Nothing of clinical significance is isolated when the bronchial lavage
fluid is cultured on blood agar plates. However, the organism grows well
on charcoal yeast extract agar with blood.
Despite antimicrobial and supportive therapy, the patient subsequently
develops multiorgan failure and dies after a protracted course.
Question 4 of 6
Which organism caused this disease?
Bordetella pertussis is an uncommon
cause of bronchopneumonia, but usually has an acute course unlike the one
described in this case. Furthermore, as the patient has been vaccinated
(DPT) he is probably immune to infections caused by Bordetella pertussis.
