Abbreviations: NCCCTS, National Collaborative Chicago-Based Congenital Toxoplasmosis Study; NE-II, nonexclusively type II; SES, socioeconomic status.
a For comparing infected and uninfected fathers were P values determined with Fisher exact tests.
b Numerator represents number of infected or uninfected fathers within a particular demographic group; denominator, total number infected or uninfected.
c Rural was defined as hometown population size <1900 at the time of the child's first visit to NCCCTS. Hispanic status was self-identified at the child's first visit. SES was calculated according to the Hollingshead 4-factor socioeconomic score.
d Not demonstrated as recently infected fathers includes uninfected fathers plus those with nonrecent Toxoplasma gondii infections (acquired >12 mo before sample collection).
e Numerator represents number of infected or uninfected fathers who have a child with this serotype; denominator represents total number of fathers infected or uninfected whose children and respective mothers were serotyped through 2009.
