RNA Atlas of Bacterial Human Pathogens Uncovers Stress Dynamics Linked to Bacterial Infections

Project description:Pathogenic bacteria encounter a variety of stressful host environments during infection. Their responses to meet these challenges protect them from deadly damages and aid in adaption to harmful environments. Bacterial products critical for this protection are therefore interesting as suitable targets for new antimicrobials. To shed light on the complex array of molecular pathways involved in bacterial stress responses we challenged 32 diverse human pathogenic bacteria to 11 infection related stress conditions and catalogued their transcriptomes. Initial analyses of the comprehensive data set showed that beside coding RNAs, known and yet unknown putative novel ncRNAs comprise a significant part of the responses. We also computed a scores for all genes to be used for predictions for their probability to be regulated at certain stresses. The core scores enabled identification of universal stress responders representing conserved gene products involved in basic mechanisms important for responses to multiple stresses. Further, the environmental specific core scores made it possible to predict functions of yet non-characterized and also hypothetical gene products. All data are collected in the PATHOGENEX interactive RNA atlas, which is made available to the research community providing ample opportunities for discovering new aspects of regulatory networks in pathogenic bacteria as well as identification of novel players critical for bacterial infectivity and maintenance of infections.

RNA atlas of human bacterial pathogens uncovers stress dynamics linked to infection.

Project description:Bacterial processes necessary for adaption to stressful host environments are potential targets for new antimicrobials. Here, we report large-scale transcriptomic analyses of 32 human bacterial pathogens grown under 11 stress conditions mimicking human host environments. The potential relevance of the in vitro stress conditions and responses is supported by comparisons with available in vivo transcriptomes of clinically important pathogens. Calculation of a probability score enables comparative cross-microbial analyses of the stress responses, revealing common and unique regulatory responses to different stresses, as well as overlapping processes participating in different stress responses. We identify conserved and species-specific 'universal stress responders', that is, genes showing altered expression in multiple stress conditions. Non-coding RNAs are involved in a substantial proportion of the responses. The data are collected in a freely available, interactive online resource (PATHOgenex).

Host-response Transcriptional Biomarkers Accurately Discriminate Bacterial and Viral Infections by Global Pathogens

Project description:Global endemic infections, such as leptospirosis, rickettsial diseases, and dengue infections present diagnostic challenges, posing a dilemma for antibiotic stewardship worldwide. The goal of this project was to identify accurate transcriptional classifiers able to discriminate between bacterial and viral illness of global pathogens.

Rapid Identification of Bacterial Pathogens using a PCR- and Microarray-Based Assay

Project description:A method based on a modified broad-range PCR and an oligonucleotide microarray for the simultaneous detection and identification of 12 bacterial pathogens at the species level. The feasibility of this assay in routine diagnostic testing was evaluated using 146 blood culture positive and 40 blood culture negative samples. The processed data are composed of ORGANISM NAME or NEGATIVE answer depending if the pathogen is detected in the sample or not. See supplementary file linked below.

Human patients with influenza virus and bacterial infections

Project description:Peripheral blood was collected from human patients infected with influenza A virus only or in addition with bacterial pathogens and at different days after hospital admission. For comparison, blood from healthy controls was collected. Gene expression differences were detected in influenza and bacterial infections compared to healthy controls, and at various days post infection.

Defining RNA Transcriptional Biosignatures to Distinguish Febrile Infants 60 Days of Age and Younger with Bacterial vs Non-Bacterial Infections

Project description:The use of microbiological cultures for diagnosing bacterial infections in young febrile infants have substantial limitations, including false positive and false negative cultures, and non-ideal turn-around times. Analysis of host genomic expression patterns (“RNA biosignatures”) in response to the presence of specific pathogens, however, may provide an alternate and potentially improved diagnostic approach. This study was designed to define bacterial and non-bacterial RNA biosignatures to distinguish these infections in young febrile infants.
