The NADH-dependent glutamate dehydrogenase enzyme of Bacteroides fragilis Bf1 is induced by peptides in the growth medium
Article Abstract:
A study was conducted to characterize the cloning and molecular features of the NADH-specific glutamate dehydrogenase (GDH) and its response to nitrogen sources. The responses were compared to the NAD(P)H-dependent GDH enzyme in Bacteroides fragilis. Standard techniques were utilized in performing general recombinant DNA manipulations. Results indicated that the gdhB gene supported a number of similarities with other cloned GDH genes. Findings also showed that the gene was closely assocaited with the hexameric GDH Family I group.

Immune reactions to Bacteroides fragilis populations with three different types of capsule in a model of infection
Article Abstract:
The survival and growth of Bacterium fragilis enriched for large capsules (LC)small capsules (SC) or an electron dense layer (EDL) were examined in mouse model of infection over a minimum period of 20 days. Chambers allowing the influx of leukocytes were implanted in the mouse peritoneal cavity. The LC and EDL populations regularly attained viable cell densities of 10 raised to 8-9 c.f.u. ml(super -1) within 24 hours but SC did not. After three days all bacterial population maintained this value within chambers.

The essential role of fumarate reductase in haem-dependent growth stimulation of Bacteroides fragilis
Article Abstract:
Research reveals the operon for the fumarate reductase contains three genes, including the haemoprotein in Bacteroides fragilis. The genes encode the cytochrome, iron-sulfur cluster protein and flavoprotein of the fumarate reductase. Data indicate that fumarate reductase is required for both energy metabolism and succinate biosynthesis in these bacteria.
