FIG 1.

Relative abundance of bacterial phyla, including Blattabacterium spp., in whole-insect samples. (a) Lab-reared and field-collected German cockroaches. Each bar depicts the mean relative abundance value of independent replicates (lab = 8, field = 20). (b) Male and female lab-reared and field-collected B. germanica cockroaches presented by location (Apt, apartment). Bars depict the mean relative abundance values of independent replicates (for Lab, male [M] = 4, female [F] = 4; for Apt1, M = 3, F = 3; for Apt2, F = 3; for Apt3, M = 2, F = 3; for Apt4, M = 3, F = 3).
