Spirochaeta coccoides sp. nov., a Novel Coccoid Spirochete from the Hindgut of the Termite Neotermes castaneus
TLDR
A novel spirochete strain, SPN1, was isolated from the hindgut contents of the termite Neotermes castaneus and represents a novel species, which was named Spirochaeta coccoides, which shows a coccoid morphology and is immotile.
“Endomicrobia”: Cytoplasmic Symbionts of Termite Gut Protozoa Form a Separate Phylum of Prokaryotes
TLDR
Evidence is provided that the members of the TG-1 phylum are phylogenetically extremely diverse and are present in and also restricted to the guts of all lower termites and wood-feeding cockroaches of the genus Cryptocercus, the only insects that are in an exclusive, obligately mutualistic association with such unique cellulose-fermenting protists.
Endomicrobium proavitum, the first isolate of Endomicrobia class. nov. (phylum Elusimicrobia)--an ultramicrobacterium with an unusual cell cycle that fixes nitrogen with a Group IV nitrogenase.
TLDR
The isolation and characterization of the first free-living member of this clade of 'Endomicrobia', a class-level lineage in the phylum Elusimicrobia, from sterile-filtered gut homogenate of defaunated (starch-fed) Reticulitermes santonensis is reported.
Identification of the ectosymbiotic bacteria of Mixotricha paradoxa involved in movement symbiosis
TLDR
Mixotricha paradoxa, a trichomonad from the hindgut of the Australian termite Mastotermes darwiniensis Froggatt, is a rare example of a movement symbiosis between eukaryotic and prokaryotic microorganisms that should represent a so far undescribed species.
Symbiotic Protozoa of Termites
TLDR
The diversity of the flagellate protozoa, their cytological features and phylogeny and several aspects of the biology and adaptations of these eukaryotes to this particular ecosystem are presented.
'Candidatus Rhabdochlamydia crassificans', an intracellular bacterial pathogen of the cockroach Blatta orientalis (Insecta: Blattodea).
TLDR
The 16S rDNA sequence of another Rickettsiella-like species, causing abdominal swelling to its cockroach host Blatta orientalis, was determined and phylogenetic analysis performed, confirming the affiliation of the cockroach pathogen within the order Chlamydiales and proposing its inclusion in the 'Candidatus Rhabdochlamydia crassificans' as a distinct taxon.
How Oxymonads Lost Their Groove: An Ultrastructural Comparison of Monocercomonoides and Excavate Taxa
TLDR
It is concluded that oxymonads have an excavate ancestry, and that the ‘excavate taxa’ sensu stricto form a paraphyletic assemblage.
The gut flagellate community of the termite Neotermes cubanus with special reference to Staurojoenina and Trichocovina hrdyi nov. gen. nov. sp.
TLDR
At least seven species of flagellates have been found to inhabit the paunch of the termite Neotermes cubanus, with the first report of a pyrsonymphid in a kalotermitid termite.
