Correlation of Antibody to Sporozoites in Maternal Serum Samples and Recognition of Exposure to Uncooked Meat Versus Material Contaminated by Oocysts From Cats
| Overall (N = 76) | Positive (n = 59) | Negative (n = 17) | P value | |
| At least 1 significant cat risk factora,b | 45 | 49 | 29 | .18 |
| Any risk factora | 84 | 83 | 88 | 1.00 |
a
Numbers are percentages.
b
Significant cat exposure is defined in Methods as cleaning a cat’s litter box, gardening, coming into contact with a sandbox, or very close, sustained contact with a kitten. Owning an indoor cat fed dry or canned food is considered a risk factor associated with cats, but not necessarily one that has substantial risk for exposure to oocysts for the cat owner.
