Anaerobic fluorescent reporters for live imaging of .

thrives in the airways of individuals with cystic fibrosis, in part by forming robust biofilms that are resistant to immune clearance or antibiotic treatment. In the cystic fibrosis lung, the thickened mucus layers create an oxygen gradient, often culminating with the formation of anoxic pockets. In this environment, can use nitrate instead of oxygen to grow.

The T3SS of : Expression, Structure, Function, and Role in Vacuole Escape.

spp. are one of the leading causes of infectious diarrheal diseases. They are pathovars that are characterized by the harboring of a large plasmid that encodes most virulence genes, including a type III secretion system (T3SS).

Diversity of bacteria associated with corn roots inoculated with Canadian woodland soils, and description of sp. nov.

Bacteria associated with corn roots inoculated with soils collected from the Canadian woodlands were isolated and characterized. Genus-level identification based on 16S rRNA sequence analysis classified the 161 isolates in 19 genera. The majority (64%) of the isolates were affiliated with the genus .

Genome analysis of two novel Pseudomonas strains exhibiting differential hypersensitivity reactions on tobacco seedlings reveals differences in nonflagellar T3SS organization and predicted effector proteins.

Multilocus sequence analysis (MLSA) of two new biological control strains (S1E40 and S3E12) of Pseudomonas was performed to assess their taxonomic position relative to close lineages, and comparative genomics employed to investigate whether these strains differ in key genetic features involved in hypersensitivity responses (HRs). Strain S3E12, at high concentration, incites HRs on tobacco and corn plantlets while S1E40 does not. Phylogenies based on individual genes and 16S rRNA-gyrB-rpoB-rpoD concatenated sequence data show strains S1E40 and S3E12 clustering in distinct groups.

Draft Genome Sequences of Two Novel Pseudomonas Strains Exhibiting Differential Hypersensitivity Reactions on Tobacco and Corn Seedlings.

Two novel Pseudomonas strains (S1E40 and S3E12) isolated from corn roots are antagonistic to Rhizoctonia solani and exhibit differential hypersensitivity reactions on tobacco and corn seedlings. We report here the draft genome sequences of strains S1E40 and S3E12, consisting of 6.98 and 7.
