Campylobacter fetus Uses Multiple Loci for DNA Inversion within the 5′ Conserved Regions of sap Homologs

Tu, Zheng-Chao, Ray, Kevin C., Thompson, Stuart A., Blaser, Martin J.

Campylobacter fetus cells possess multiple promoterless sap homologs, each capable of expressing a surface layer protein (SLP) by utilizing a unique promoter present on a 6.2-kb invertible element....

Evidence that the Campylobacter fetus sap Locus Is an Ancient Genomic Constituent with Origins before Mammals and Reptiles Diverged

Tu, Zheng-Chao, Dewhirst, Floyd E., Blaser, Martin J.

Campylobacter fetus bacteria, isolated from both mammals and reptiles, may be either subsp. fetus or subsp. venerealis and either serotype A or serotype B. Surface layer proteins, expressed and...

Campylobacter fetus sap Inversion Occurs in the Absence of RecA Function

Ray, Kevin C., Tu, Zheng-Chao, Grogono-Thomas, Rosemary, Newell, Diane G., Thompson, Stuart A., Blaser, Martin J.

Phase variation of Campylobacter fetus surface layer proteins (SLPs) occurs by inversion of a 6.2-kb DNA segment containing the unique sap promoter, permitting expression of a single SLP-encoding...

Conservation and Diversity of sap Homologues and Their Organization among Campylobacter fetus Isolates

Tu, Zheng-Chao, Hui, John, Blaser, Martin J.

Campylobacter fetus surface layer proteins (SLPs), encoded by sapA homologues, are important in virulence. In wild-type C. fetus strain 23D, all eight sapA homologues are located in the 54-kb sap...

Campylobacter fetus of Reptile Origin as a Human Pathogen

Tu, Zheng-Chao, Zeitlin, Gary, Gagner, Jean-Pierre, Keo, Thormika, Hanna, Bruce A., Blaser, Martin J.

A Campylobacter species was isolated from blood from a febrile patient with precursor T-cell acute lymphoblastic leukemia, and after antibiotic treatment, a similar bacterium was isolated from blood...

Genetic Divergence of Campylobacter fetus Strains of Mammal and Reptile Origins

Tu, Zheng-Chao, Eisner, William, Kreiswirth, Barry N., Blaser, Martin J.

Campylobacter fetus is a gram-negative bacterial pathogen of both humans and animals. Two subspecies have been identified, Campylobacter fetus subsp. fetus and Campylobacter fetus subsp. venerealis,...
