Gross hydrosalpinx scores following primary and secondary infections with differing doses

Infectiona	Doseb	No. of OD with score ofc:
		0	1	2	3
1°	1 × 107	17	6	9	2
	1.5 × 105	12	8	5	7
	1 × 104	10	13	9	2
2°	1 × 107	6	9	14	3
	1.5 × 105	9	11	8	4

^a1°, primary infection; 2°, repeat infection.

^bThere was no statistical difference by dose in the number of oviducts with respective hydrosalpinx scores by Spearman rank order correlation (P > 0.05).

^cNumber of oviducts per dose assigned respective hydrosalpinx scores based on gross diameter following removal of genital tracts from mice 49 days post-primary infection (1°) or 6 days after a repeat infection (2°). Data are representative of results from four independent experiments with four to seven mice per experiment. Hydrosalpinx scores are as follows: 0, none; 1, increase; 2, 2.5 mm in diameter; and 3, ≥ 3.5 mm in diameter.
