  1. Nn and Nall refer to the number of nests and microsatellite alleles. Five worker ants were screened from each nest. Hexp = expected heterozygosity, r = relatedness and F = inbreeding coefficient. The standard error of relatedness was obtained by jackknifing over the nests. Number of infected nests is given for each bacterium (Serr, Wolb, Card) and for double infections (SW, SC and WC).
