“…Previous studies have characterized microbial communities of cockroaches, primarily the gut microbiome. Consistent with our findings, Bacteroidetes, Firmicutes, Proteobacteria, and unclassified bacteria are repeatedly found to be prominent members of adult cockroach endosymbiont communities (Bauer et al, ; Bertino‐Grimaldi et al, ; Carrasco et al, ; Gontang et al, ; Kakumanu, Maritz, Carlton, & Schal, ; Pérez‐Cobas et al, ; Schauer, Thompson, & Brune, ; Tinker & Ottesen, ). Similar to our adult female samples, other studies have shown Porphyromonadaceae, Rikenellaceae, and Bacteroidaceae to be the most abundant families of Bacteroidetes; while Lachnospiraceae, Ruminococcaceae, Clostridiaceae, and Lactobacillaceae are commonly represented Firmicutes (Bauer et al, ; Bertino‐Grimaldi et al, ; Carrasco et al, ; Gontang et al, ; Kakumanu et al, ; Pérez‐Cobas et al, ; Sabree & Moran, ; Schauer et al, ; Tinker & Ottesen, ).…”
