Unusual cell wall ultrastructure of Leptotrichia buccalis.
Leptotrichia buccalis was examined by transmission electron microscopy. Its cell wall structure in generally compatible with that of gram-negative bacteria. However, the scale-like membranous folds associated with the external surface of the outer cell membrane appear to be sufficiently unusual to serve as a useful morphological criterion in the identification of L. baccalis cells.
متن کاملLeptotrichia Buccalis: A Novel Cause of Chorioamnionitis
Intra-amniotic Leptotrichia buccalis has not been previously associated with adverse pregnancy outcome. We report a case of chorioamnionitis and pregnancy loss associated with this primarily oral commensal. We review Leptotrichia buccalis and other oral commensals that have been identified in cases of intraamniotic infection.
متن کاملLeptotrichia buccalis bacteremia in neutropenic children.
Two new cases of Leptotrichia buccalis bacteremia in seriously ill patients were described. The anaerobic, gram-negative microorganism L. buccalis was isolated from blood cultures of two children with severe leukopenia. Anaerobic organisms should be taken into account when a standard protective antibiotic chemotherapy is considered in the immunosuppressed host.

متن کاملOral Fusobacteria.
The genus Fusobacterium was proposed by Knorr (1922) for the pointed, nonsporulating, gram-negative, anaerobic bacilli found in the oral cavity. On the basis of morphology, three species were named, Fusobacterium nucleatum, Fusobacterium polymorphum, and Fusobacterium plauti-vincentii. Similarly, Hine and Berry (1937) described three species, based primarily on morphological and cultural charac...
