Collagenolytic activity of bacteria.
Actively growing aerobic and anaerobic bacteria were screened by a plate assay, with reconstituted guinea pig collagen as a substrate, for their ability to produce a collagenolytic factor. Collagenolytic activity was not demonstrated among the aerobic organisms tested, with the exception of one strain of Staphylococcus aureus (only when grown under anaerobic conditions). Collagenolytic activity...

متن کاملCollagenolytic activity in traumatized human primary teeth undergoing accelerated resorption.
Human pe~odont~l ligamen~ from rapidly resorbing pzqmary teeth which also exhibited periapical radiolucency on radiograph demonstrated co]]agenolytic activity when incubated on collagen gels. This activity was direc~ly proportional ~o the size of the explant and length of time of incubation.
متن کاملCollagenolytic activity of Coccidioides immitis.
Coccidioides immitis appears to be unable to digest particulate collagen when cultured on collagen-containing semisolid culture media. However, all C. immitis strains solubilized collagen when the fungus was grown in liquid suspension cultures. Moreover, sterile culture filtrates were collagenolytic in collagen-buffer-agar plate assays.
متن کاملHistopathological study of radicular cysts diagnosed in a Brazilian population.
The aim of this study was to investigate the histopathological features of radicular cysts (RCs) diagnosed in a Brazilian population. Seventy-three cases of RCs, from a total of 1480 biopsies diagnosed between 2001 and 2008 at the Laboratory of Oral Surgical Pathology of the Dental School of the Federal University of Bahia were investigated regarding their histopathological features. Morphologi...
