Internalin of Listeria monocytogenes with an intact leucine-rich repeat region is sufficient to promote internalization.

Lecuit, M, Ohayon, H, Braun, L, Mengaud, J, Cossart, P

Listeria monocytogenes can use two different surface proteins, internalin (InlA) and InlB, to invade mammalian cells. The exact role of these invasiveness factors in vivo remains to be determined. In...

OlpB, a new outer layer protein of Clostridium thermocellum, and binding of its S-layer-like domains to components of the cell envelope.

Lemaire, M, Ohayon, H, Gounon, P, Fujino, T, Béguin, P

Several proteins of Clostridium thermocellum possess a C-terminal triplicated sequence related to bacterial cell surface proteins. This sequence was named the SLH domain (for S-layer homology), and...

Characterization and subcellular localization of the Clostridium thermocellum scaffoldin dockerin binding protein SdbA.

Leibovitz, E, Ohayon, H, Gounon, P, Béguin, P

This article reports the characterization of the Clostridium thermocellum SdbA protein thought to anchor the cellulosome to the bacterial cell surface. The NH2-terminal region of SdbA consists of a...

Multiple drug resistance in Mycobacterium avium: is the wall architecture responsible for exclusion of antimicrobial agents?

Rastogi, N, Frehel, C, Ryter, A, Ohayon, H, Lesourd, M, David, H L

Whole cells of Mycobacterium avium, characterized by their negative response in the nine biochemical tests used for mycobacterial identification in our laboratory, turned positive for nitrate...

Subcellular localization of Clostridium thermocellum ORF3p, a protein carrying a receptor for the docking sequence borne by the catalytic components of the cellulosome.

Salamitou, S, Lemaire, M, Fujino, T, Ohayon, H, Gounon, P, Béguin, P, ...

The ORF3 gene of Clostridium thermocellum encodes a polypeptide (ORF3p) which contains a receptor domain for the docking sequence borne by the catalytic subunits of the cellulosome and a triplicated...

Nucleotide sequence of the lecithinase operon of Listeria monocytogenes and possible role of lecithinase in cell-to-cell spread.

Vazquez-Boland, J A, Kocks, C, Dramsi, S, Ohayon, H, Geoffroy, C, Mengaud, J, ...

The lecithinase gene of the intracellular pathogen Listeria monocytogenes, plcB, was identified in a 5,648-bp DNA fragment which expressed lecithinase activity when cloned into Escherichia coli. This...

Experimental cecitis in gnotoxenic chickens monoassociated with Clostridium butyricum strains isolated from patients with neonatal necrotizing enterocolitis.

Popoff, M R, Szylit, O, Ravisse, P, Dabard, J, Ohayon, H

An animal model for Clostridium butyricum necrotizing cecitis has been developed in axenic chickens inoculated orally between 2 and 50 days of life. Cecitis was obtained with two C. butyricum strains...
