Table 2. Expressed msp2 allelic diversity over time (in weeks) in three woodrat chronic infections of A. phagocytophilum.

Gene diversity, H, fluctuates over time, as does the observed number of alleles, A, and the effective number of alleles, A_e. The size of the pseudogene library remaining, psleft, reflects the starting state of about 100 pseudogenes and the number of distinct pseudogenes already expressed.
