Q009 MHC class II molecules are expressed by A) B 1A and C 2 A 3 B and D 4 A,B,C, and D cells; B) Erythrocytes. C) Macrophages D) Hepatocytes 0010 Two patients were suspected of exposure to a rare parasite. When sera from these patients were analyzed, patient A had mostly IgM antibodies to the infectious agent while patient B had a very high titer of mostly IgG, What can you conclude from these results. 1 Patient B has been infected with the parasite for a long time or has been infected multiple times 2 Patient A is resistant to the infection 3 Patient B might have been infected very recently by the parasite 4 Some antibodies in patient A's serum might have become degraded 5 Niether patient has been exposed to the parasiteExplanation / Answer
