B)Blood serum
C)Mucus


3A doctor's office saw two different patients, one week apart, with similar symptoms. Bacterial infection was suspected and blood samples were taken from both students. Serological tests were performed on both samples using the same prepared, known, antigen. Both samples had visible agglutination reactions. Which of the following conclusions can be drawn from the lab work?
A)The students were exposed to similar strains of bacteria.
B)The students were exposed to the same strain/serotype of bacteria.


4Referring to the lab tests done in question 3: Both samples had visible agglutination reactions with the same prepared, known, antigen; however one of the samples demonstrated agglutination after 15 seconds, while the other sample took 2 minutes to agglutinate. Which of the following answers explains this phenomenon?
A)The sample that took 15 seconds to agglutinate contains more antibody than the sample that took two minutes to agglutinate.
B)The sample that took 15 seconds to agglutinate contains less antibody than the sample that took two minutes to agglutinate.


5When serological testing is done to identify an unknown organism, it is not necessary to have known antibodies.
A)True
B)False
