Small Heat Shock Proteins Produced by Pseudomonas Aeruginosa Clonal Variants Isolated from Diverse Niches

Adaptation of Mycoplasmas to Antimicrobial Peptides: Development of Melittin Resistance in Acholeplasma laidlawii Is Associated with Changes in Genomic and Proteomic Profiles and in Virulence

For the first time it is shown that the development of resistance to melittin in Acholeplasma laidlawii, a mycoplasma that is widely spread in nature and that is the main contaminant of cell cultures and vaccines, is associated with significant changes in the genomic profile, in cellular and vesicular proteomes, as well as in virulence.

Transcriptome analysis of Pseudomonas aeruginosa PAO1 grown at both body and elevated temperatures

Functional genomics research can give us valuable insights into bacterial gene function. RNA Sequencing (RNA-seq) can generate information on transcript abundance in bacteria following abiotic stress treatments. In this study, we used the RNA-seq technique to study the transcriptomes of the opportunistic nosocomial pathogen Pseudomonas aeruginosa PAO1 following heat shock. Samples were grown at both the human body temperature (37 °C) and an arbitrarily-selected temperature of 46 °C. In this work using RNA-seq, we identified 133 genes that are differentially expressed at 46 °C compared to the human body temperature. Our work identifies some key P. aeruginosa PAO1 genes whose products have importance in both environmental adaptation as well as in vivo infection in febrile hosts. More importantly, our transcriptomic results show that many genes are only expressed when subjected to heat shock. Because the RNA-seq can generate high throughput gene expression profiles, our work reveals many unanticipated genes with further work to be done exploring such genes products.
