Table 2.

Babesia prevalence, with Jefferys confidence intervals (Jeff. C.I.), among medium sized mammals sampled from two sites in eastern Texas (Gus Engeling WMA and Big Thicket National Preserve). Additionally, 427 small mammals from 10 species from these sites were tested but no positives were detected. For a distribution of sample sizes tested per species and site see Table 2. Positives columns represent numbers of infected individuals (outside parenthesis) and total sample size (n, in parenthesis).
