the arthromitus stage of bacillus cereus: intestinal symbionts of animals.in the guts of more than 25 species of arthropods we observed filaments containing refractile inclusions previously discovered and named "arthromitus" in 1849 by joseph leidy [leidy, j. (1849) proc. acad. nat. sci. philadelphia 4, 225-233]. we cultivated these microbes from boiled intestines of 10 different species of surface-cleaned soil insects and isopod crustaceans. literature review and these observations lead us to conclude that arthromitus are spore-forming, variably motile, cultivable ba ...19989448315
coevolution of symbiotic spirochete diversity in lower termites.the phylogenetic relationships of symbiotic spirochetes from five dry-wood feeding lower termites (cryptotermes cavifrons, heterotermes tenuis, kalotermes flavicollis, neotermes mona, and reticulitermes grassei) was compared to those described in previous reports. the 16s rdna bacterial genes were pcr-amplified from dna isolated from intestinal samples using a spirochete-selective primer, and the 16s amplicons were cloned into escherichia coli. sequences of the cloned inserts were then used to d ...200717661292
iridoid glucosides with insecticidal activity from galium melanantherum.the insecticidal activity of the endemic species galium melanantherum was evaluated against crematogaster scutellaris ants and kalotermes flavicollis termites. iridoid glucosides 1-7 were isolated for the first time as metabolites of the investigated plant, along with the coumarin scopolin. the main components of the extract were found to be the non-acetylated iridoids: geniposidic acid (1), 10-hydroxyloganin (2), deacetyldaphylloside (3), monotropein (4), deacetylasperulosidic acid (5) and scan ...200717913079
identification and localization of the multiple bacterial symbionts of the termite gut flagellate joenia annectens.the hindgut of wood-feeding lower termites is densely colonized by a multitude of symbiotic micro-organisms. while it is well established that the eukaryotic flagellates play a major role in the degradation of lignocellulose, much less is known about the identity and function of the prokaryotic symbionts associated with the flagellates. our ultrastructural investigations of the gut flagellate joenia annectens (from the termite kalotermes flavicollis) revealed a dense colonization of this flagell ...201020378649
molecular characterization and phylogeny of kalotermes populations from the levant, and description of kalotermes phoeniciae sp. nov.the presence of the yellow-necked drywood termite, kalotermes flavicollis fabr., has been reported along most of the mediterranean coasts of europe, africa and asia. while morphological and genetic data exist on european k. flavicollis populations from western and central mediterranean regions, data on eastern mediterranean kalotermes are scarce, and no genetic data exist to date. in this study, we analyzed 17 kalotermes sp. colonies from 11 localities in the levant (cyprus, lebanon, and israel) ...201525779003
phylogeny and ultrastructure of oxymonas jouteli, a rostellum-free species, and opisthomitus longiflagellatus sp. nov., oxymonadid flagellates from the gut of neotermes jouteli.the biodiversity of oxymonadid flagellates in termite hindguts is not fully explored. many species have been differentiated only by morphological features, and small-celled species have been overlooked or ignored. our analysis of the dry wood termite neotermes jouteli by light and electron microscopy revealed the presence of two distinct morphotypes of oxymonads. the larger one matched the morphology of oxymonas jouteli, the only oxymonad species described from this termite. although it generall ...201424878512
