TABLE 1.

Coinfection increases the percentage of neutrophils with Ehrlichia^a

Infectionb	% (mean ± SD) of neutrophils with morulaec at:
	1 wk	2 wk
Uninfected (control)	0	0
HGE	6.8 ± 1.9	0.3 ± 0.5
HGE and B. burgdorferi	17 ± 1.4d	3.3 ± 1.7e

^aResults from one of four separate experiments with similar results are shown. 

^bGroups of five mice were either infected with HGE bacteria, coinfected with HGE bacteria and B. burgdorferi, or remained uninfected (control). 

^cThe percentage of neutrophils with morulae was assessed by analysis of 100 granulocytes in duplicate blood smears from each of the four mice in each infected group. 

^dP < 0.0001 relative to HGE-infected mice. 

^eP < 0.02 relative to the HGE-infected mice.
