You Are Looking After Your Sister's Cat Singa

You are looking after your sister's cat Singa. While playing one evening, Singa accidentally bites you instead of the toy mouse you are holding. The bite wound is very small but is in the fleshy part of your hand. You wash the wound, which is not bleeding much, and put a band aid on it. The next day, your whole hand is red, swollen, and painful, and some lymph nodes in your arm are enlarged and tender. You call your sister, who is an RN. She urges you to go to the doctor, telling you that animal bites can sometimes be infected, and that if that is the case, you will need treatment before the infection gets any worse.
-The PA goes on to explain that cat bite infections and bartonellosis (cat scratch disease) differ in that

A) P. multicoda is a Gram-positive organism while B. henselae is a Gram-negative organism.
B) P. multicoda is transmitted by cat bites, while B. henselae may be transmitted by bites or scratches.
C) P. multicoda may be transmitted form person-to-person while B. henselae can only be transmitted by cat bites.
D) the virulence factors of P. multicoda are as yet unknown while B. henselae has an antiphagocytic capsule.
E) cat bite infections can be prevented with prophylactic antibiotics while bartonellosis may be prevented with an attenuated vaccine.
