Table 3. Bacterial taxon richness and diversity in Triatoma sordida gut.
Operational Taxonomic Units (OTUs) were defined based on a 97% 16S rRNA sequence identity cutoff.

* Sample codes are composed of a first character that identifies the bugs’ development stage (4, 4th stage nymphs; 5, 5th stage nymphs; F, adult female; M, adult male), followed by letters that identify intestinal segments (AM, anterior midgut; PM, posterior midgut; H, hindgut)
