TABLE 3.

IgG endpoint titers are similar in vector-borne infection of WT and MyD88^−/− mice, but accurate detection is B. burgdorferi strain specific^e

Mouse group	No. of positive blood cultures/total no.	Endpoint IgG ELISA titer ± SEM using:
		BL206 antigen	B348 antigen
BL206-infected WT	0/4	22,500 ± 3,200	19,200 ± 3,695
BL206-infected MyD88−/−	5/5a	37,120 ± 22,933b	15,360 ± 5,724
B348-infected WT	0/4	2,000 ± 400	12,800 ± 5,226
B348-infected MyD88−/−	4/5c	3,520 ± 1,176d	16,000 ± 6,072

^aThese results were significantly different from WT values (P = 0.0079; Fisher's exact test).

^bNo significant difference from WT values (P = 0.6201; Mann-Whitney test).

^cThese results were significantly different from WT values (P = 0.0476; Fisher's exact test).

^dNo significant difference from WT values (P = 0.6129; Mann-Whitney test).

^eAll skin, heart, and joint cultures were culture positive (data not shown).
