FINAL EXAM SLIDO Flashcards
(23 cards)
What do we call a disease that can be transferred to another host during the incubation period, before the first person shows any signs of disease?
Communicable disease
Which type of bacteria are more resistant to antibodies
Gram negative
Would immunocompromised patients need more or less strains of bacteria to become infected?
Only takes a few to cause disease because immune system is already weak
Why are serious fungal infections hard to treat in humans?
We BOTH have nuclei
Fungi thrive in acidic environments, and gram positive bacteria is acidic. So, if there is an imbalance and disruption of the normal flora… What will happen?
More fungi will grow in this environment
What are spherical bacteria called?
Cocci
Which bacterial growth curve phase has no overall population growth?
Stationary
Which type of bacteria releases endotoxins?
Gram (-) = Lipopolysaccharide
Which RNA can result in a worse infection?
Positive, because can replicate faster
