Localities (1- Cururupu; 2- São Bento; 3- Açailândia; 4- Grajaú; 5- Barreirinhas; 6- Caxias; 7- São Domingos; 8- Balsas) where domestic dogs were sampled in the state of Maranhão, northeastern Brazil.

<p>Pie charts represent the proportions of seropositive and seronegative dogs in urban and rural areas in each locality (Urban dogs +: seropositive dogs in the urban area; Urban dogs -: seronegative dogs in the urban area; Rural dogs +: seropositive dogs in the rural area; Rural dogs -: seronegative dogs in the rural area). Percent numbers above each pie chart represent canine seroreactivity values in urban and rural areas (lower numbers), and total canine seropositivity (top number). Different lower case letters inside parenthesis mean statistically different (<i>P</i><0.05) total seroreactivity values between the 8 localities. The distribution of <i>Amblyomma cajennense</i> s.s. and <i>Amblyomma sculptum</i> in the map was retrieved from the study of Martins et al.[<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0179163#pone.0179163.ref009" target="_blank">9</a>].</p>
