Table 3.
Prevalence and levels (titers) of serovar-specific anti-Leptospira antibodies measured by the microscopic agglutination test (MAT) among cattle slaughtered at major Ugandan abattoirs (N = 500).

Npos*titer refers to the number of cattle with the various levels of antibodies (titers) and Npos* serovar to those reacting against the respective Leptospira serovars/serogroups tested.
CI, Confidence interval; MAT, microscopic agglutination test.
