a

Number of sampled rodents;

b

Number of rodents considered for serological analyses;

c

Seroprevalence of T. gondii;

d

Simpson’s diversity index;

e

Trap success, calculated as the ratio between the number of rodents sampled and the number of traps set in the houses, minus non-active traps (e.g., those found closed and empty, or those having captured small mammals other than rodents);

f

Number of individuals sampled/Number of individuals serotyped/Number of seropositive individuals.
