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.
Geobacillus thermoleovorans CCB_US3_UF5 is a thermophilic bacterium isolated from a hot spring in Malaysia. Here, we report the complete genome of G. thermoleovorans CCB_US3_UF5, which shows high similarity to the genome of Geobacillus kaustophilus HTA 426 in terms of synteny and orthologous genes.
Thermus sp. strain CCB_US3_UF1, a thermophilic bacterium, has been isolated from a hot spring in Malaysia. Here, we present the complete genome sequence of Thermus sp. CCB_US3_UF1.
We report here the complete genome sequence of Salmonella enterica subsp. enterica serovar Typhi P-stx-12, a clinical isolate obtained from a typhoid carrier in India.
Thermus sp. strain CCB_US3_UF1 is a thermophilic bacterium of the genus Thermus, a member of the family Thermaceae. Members of the genus Thermus have been widely used as a biological model for structural biology studies and to understand the mechanism of microbial adaptation under thermal environments. Here, we present the complete genome sequence of Thermus sp. CCB_US3_UF1 isolated from a hot spring in Malaysia, which is the fifth member of the genus Thermus with a completely sequenced and publicly available genome (Genbank date of release: December 2, 2011). Thermus sp. CCB_US3_UF1 has the third largest genome within the genus. The complete genome comprises of a chromosome of 2.26 Mb and a plasmid of 19.7 kb. The genome contains 2279 protein-coding and 54 RNA genes. In addition, its genome revealed potential pathways for the synthesis of secondary metabolites (isoprenoid) and pigments (carotenoid).
