Clinical and hematologic findings during the acute phase of infection in mice infected with Ehrlichia muris–like agent (EMLA) by the intravenous route. A, Change in the body weight of mice infected with lethal and sublethal doses of EMLA. B, Serum concentration of alanine aminotransferase (ALT) in mice lethally infected with EMLA on day 10 after infection. C, Total white blood cell (WBC) and differential cell counts in mice lethally infected with EMLA. D, Hematocrit values in lethally infected animals. E, Platelet counts in lethally infected mice. Bars represent means ± SD. Control and EMLA-infected groups were compared by an unpaired t test. *P < .05 and **P < .01. Abbreviations: LD₅₀, median lethal dose; LY, lymphocyte; MO, monocyte; NE, neutrophil.
