To stabilize cellular integrity in the face of environmental perturbations, most bacteria, including cyanobacteria, synthesize and
maintain a strong, flexible, three-dimensional peptidoglycan lattice. Anabaena sp. strain PCC 7120 is a filamentous cyanobacterium
capable of differentiating morphologically distinct nitrogen-fixing heterocyst cells in a periodic pattern. While heterocyst
development has been shown...

The draft genome of Streptomyces sp. strain ventii, an environmental isolate recovered from deep-sea hydrothermal vents in the Pacific Ocean, is presented along with the resequenced draft genomes of the type strains Streptomyces bohaiensis 11A07 and Streptomyces lonarensis NCL 716.
Vibrio bacteria are commonly found in freshwater, marine, and estuarine environments. Members of this genus can exist in commensal relationships with marine animals or as planktonic bacteria, however, they are well known for their roles as pathogens towards humans and animals. In this dissertation, I investigated aspects of host-bacteria relationships...
Plasmid transformation of chlamydiae has created new opportunities to investigate host–microbe interactions during chlamydial infections; however, there are still limitations. Plasmid transformation requires a replicon derived from the native Chlamydia plasmid, and these transformations are species-specific. We explored the utility of a broad host-range plasmid, pBBR1MCS-4, to transform chlamydiae, with...
A digoxigenin-labeled nonradioactive detection system was used
to screen a zebrafish cDNA library for p53-like and ras-like genes.
One clone was isolated and identified as an incomplete p53-like
gene. The insert size of this clone is 1777 bp, which encodes part of
evolutionarily conserved region II and all of regions...
Melanocytes are dendritic, pigment-producing cells located in the skin and are responsible for its protection against the deleterious effects of solar ultraviolet radiation (UVR), which include DNA damage and elevated reactive oxygen species (ROS). They do so by synthesizing photoprotective melanin pigments and distributing them to adjacent skin cells (e.g.,...
Chlamydia is an obligate intracellular bacterial pathogen that causes a variety of disease in animals and humans worldwide. Veterinary chlamydial pathogens can lead to chronic infections and serious consequences that result in millions of dollars of losses in animals and resources in the agricultural industry in countries that rear ruminants....
