Identification of a Mycobacterium tuberculosis Gene That Enhances Mycobacterial Survival in Macrophages

Wei, Jun, Dahl, John L., Moulder, James W., Roberts, Esteban A., O'Gaora, Peadar, Young, Douglas B., ...

Intracellular survival plays a central role in the pathogenesis of Mycobacterium tuberculosis. To identify M. tuberculosis genes required for intracellular survival within macrophages, an M....

Subcellular Localization of the Intracellular Survival-Enhancing Eis Protein of Mycobacterium tuberculosis

Dahl, John L., Wei, Jun, Moulder, James W., Laal, Suman, Friedman, Richard L.

Mycobacterium tuberculosis is a facultative intracellular pathogen that has evolved the ability to survive and multiply within human macrophages. It is not clear how M. tuberculosis avoids the...

The role of RelMtb-mediated adaptation to stationary phase in long-term persistence of Mycobacterium tuberculosis in mice

Dahl, John L., Kraus, Carl N., Boshoff, Helena I. M., Doan, Bernard, Foley, Korrie, Avarbock, David, ...

Long-term survival of nonreplicating Mycobacterium tuberculosis (Mtb) is ensured by the coordinated shutdown of active metabolism through a broad transcriptional program called the stringent...

Analysis of the Immune Response to Mycobacterium avium subsp. paratuberculosis in Experimentally Infected Calves

Koo, Hye Cheong, Park, Yong Ho, Hamilton, Mary Jo, Barrington, George M., Davies, Christopher J., Kim, Jong Bae, ...

Johne's disease of cattle is widespread and causes significant economic loss to producers. Control has been hindered by limited understanding of the immune response to the causative agent,...

The relA Homolog of Mycobacterium smegmatis Affects Cell Appearance, Viability, and Gene Expression

Dahl, John L., Arora, Kriti, Boshoff, Helena I., Whiteford, Danelle C., Pacheco, Sophia A., Walsh, Olaus J., ...

The modification of metabolic pathways to allow for a dormant lifestyle appears to be an important feature for the survival of pathogenic bacteria within their host. One regulatory mechanism for...

CbgA, a Protein Involved in Cortex Formation and Stress Resistance in Myxococcus xanthus Spores▿

Tengra, Farah K., Dahl, John L., Dutton, David, Caberoy, Nora B., Coyne, Lia, Garza, Anthony G.

CbgA plays a role in cortex formation and the acquisition of a subset of stress resistance properties in Myxococcus xanthus spores. The cbgA mutant produces spores with thin or no cortex layers, and...

Identification of Major Sporulation Proteins of Myxococcus xanthus Using a Proteomic Approach▿

Dahl, John L., Tengra, Farah K., Dutton, David, Yan, Jinyuan, Andacht, Tracy M., Coyne, Lia, ...

Myxococcus xanthus is a soil-dwelling, gram-negative bacterium that during nutrient deprivation is capable of undergoing morphogenesis from a vegetative rod to a spherical, stress-resistant spore...

Demonstration of Allelic Exchange in the Slow-Growing Bacterium Mycobacterium avium subsp. paratuberculosis, and Generation of Mutants with Deletions at the pknG, relA, and lsr2 Loci▿

Park, Kun Taek, Dahl, John L., Bannantine, John P., Barletta, Raúl G., Ahn, Jongsam, Allen, Andrew J., ...

Mycobacterium avium subsp. paratuberculosis is the causative pathogen of Johne's disease, a chronic inflammatory wasting disease in ruminants. This disease has been difficult to control because of...

Inactivation of lsr2 Results in a Hypermotile Phenotype in Mycobacterium smegmatis▿ †

Arora, Kriti, Whiteford, Danelle C., Lau-Bonilla, Dalia, Davitt, Christine M., Dahl, John L.

Mycobacterial species are characterized by the presence of lipid-rich, hydrophobic cell envelopes. These cell envelopes contribute to properties such as roughness of colonies, aggregation of cells in...
