Journal ArticleDOI
Distribution and Abundance of Bacteria in the Gut of a Soil-feeding Termite Procubitermes aburiensis (Termitidae, Termitinae)
TL;DR: Transmission and scanning electron microscopy of the gut wall showed that the actinomycetes formed novel associations with the host in the mesenteron, mixed segment and colon, and were present in large numbers in the contents of the third proctodaeal segment.
Journal ArticleDOI
Structure, microbial associations and function of the so‐called “mixed segment” of the gut in two soil‐feeding termites, Procubitermes aburiensis and Cubitermes severus (Termitidae, Termitinae)
TL;DR: The morphology, histology and ultrastructure of the mesenteric and proctodaeal components of the mixed segment are described in detail, together with the disposition of the associated gut musculature, the patterns of peristalsis and the streaming movements of soil particles in the gut lumen.
Journal ArticleDOI
Specialization of the hindgut wall for the attachment of symbiotic micro-organisms in a termite Procubitermes aburiensis (Isoptera, Termitidae, Termitinae)
TL;DR: The posterior colon of worker-caste termites accommdates an abundant, heterogeneous population of procaryotic organisms which are retained by attachment to prominent cuticular spines elaborated from the gut wall.
Journal ArticleDOI
Colonization of the epithelial face of the peritrophic membrane and the ectoperitrophic space by actinomycetes in a soil-feeding termite
Journal ArticleDOI
Formation of membrane-bounded secretory granules in the midgut epithelium of a termite, Cubitermes severus , and a possible intercellular route of discharge
TL;DR: Evidence suggests that absorptive functions are reduced in the midgut of this insect and that apical surface area by microvilli is less prominent in Cubitermes than in other termites for which data are available.
