- Why is MRSA more pathogenic than other strains of Staphylococcus
aureus?
A. MRSA has increased antibiotic resistance
, B. MRSA produces an enterotoxin
C. MRSA resists degradation by phagocytes

at home, they noticed swelling and redness at their incision site. How would
this infection be classified?
A. Latrogenic
B. Zoonotic
C. Noncommunicable
D. Vectors-transmitted - -A. Iatrogenic

annually?

clotting of blood to protect the bacteria in the bloodstream, then a digestion
of the clots to allow the bacteria to spread?

cells genome - -A. Coinfection provides the opportunity for an antigenic
shift.
