Two distinct types of hematological leukocyte kinetics among adult and newly weaned ferrets after H1N1pdm infection. Hematological cells were counted for total leukocytes (A), lymphocytes (B), monocytes (C), neutrophils (D), eosinophils (E), and basophils (F) in adult and newly weaned ferrets on the indicated days for 2 weeks after initial leukocyte sampling. A minimum of three samples from each time point were collected per group. K/μl, thousands of cells per microliter. Error bars represent standard errors of the means. *, P < 0.05 by Student's t test comparing infected adult and young ferrets on the same corresponding days.
