Whole-genome in vitro expression analysis of F. tularensis isolates grown to mid log phase

ABSTRACT: This study was aimed to perform comparative expression analysis of both virulent and avirulent strains of F. tularensis with a goal to possibly identify genes unique to low and high virulent strains to understand their role, if any in virulence features of an isolate. Initially, thirty strains were selected representing both type A and type B clades of F. tularensis. Five strains failed to grow on Chamberlain's medium (Chamberlain 1965) and were excluded from the study. All the isolates were grown to mid-log phase in Chamberlain’s medium and the total RNA was collected by standard protocols for expression analysis. The samples were analyzed in duplicates. F. tularensis Schu S4, a known virulent strains was used as a reference strain for this study. Chamberlain RE (1965) "Evaluation of Live Tularemia Vaccine Prepared in a Chemically Defined Medium," Applied Microbiology, 13(2): 232-5 Twenty four query strains and one reference strain (FRAN016 Schu S4) were used in the hybridizations. Most of the hybridizations have more than one biological replicates, resulting in a total of fifty five samples analyzed.

Project description:Staphylococcus aureus is a Gram-positive human pathogen causing a variety of human diseases in both hospital and community settings. This bacterium is so closely associated with prophages that it is rare to find S. aureus isolates without prophages. Two phages are known to be important for staphylococcal virulence: the beta-hemolysin (hlb) converting phage and the Panton-Valentine Leukocidin (PVL) converting phage. The hlb-converting phage is found in more than 90% of clinical isolates of S. aureus. This phage produces exotoxins and immune modulatory molecules, which inhibit human innate immune responses. The PVL-converting phage produces the two-component exotoxin PVL, which can kill human leucocytes. This phage is wide-spread among community-associated methicillin resistant S. aureus (CA-MRSA). It also shows strong association with soft tissue infections and necrotizing pneumonia. Several lines of evidence suggest that staphylococcal prophages increase bacterial virulence not only by providing virulence factors but also by altering bacterial gene expression: 1) Transposon insertion into prophage regulatory genes, but not into the genes of virulence factors, reduced S. aureus killing of Caenorhabditis elegans.; 2) Although the toxins and immune modulatory molecules encoded by the hlb- converting phages do not function in the murine system, deletion of NM3, the hlb-converting phage in S. aureus Newman, reduced staphylococcal virulence in the murine abscess formation model. 3) In a preliminary microarray experiment, prophages in S. aureus Newman altered the expression of more than 300 genes. In this research proposal, using microarray and high-throughput quantitative RT-PCR (qRT-PCR) technologies, we will identify the effects of the two important staphylococcal phages on the gene expression of S. aureus in both in vitro and in vivo conditions. This project is intended to be completed within one year. All the data – microarray, qRT-PCR and all the primer sequences- will be made available to public 6 month after completion. Data from this project will help us to understand the role of prophages in the S. aureus pathogenesis and can lead to development of a strategy to interfere with the pathogenesis process. Staphylococcus aureus subsp.aureus strain Newman (reference) and Staphylococcus aureus subsp.aureus strain Newman yhcR knockout(query) were grown in TSA broth.Samples were grown under aerobic and anaerobic conditions and RNA samples harvested at mid log, stationary, and log phases.Samples were hybridized on aminosilane coated slides with 70-mer oligos.

Project description:The induction of genetic competence is a strategy used by bacteria to increase their genetic repertoire under stressful environmental conditions. Recently, Streptococcus pneumoniae has been shown to co-ordinate the uptake of transforming DNA with fratricide via increased expression of the peptide pheromone responsible for competence induction. Here, we document that environmental stress-induced expression of the peptide pheromone competence-stimulating peptide (CSP) in the oral pathogen Streptococcus mutans. We showed that CSP is involved in the stress response and determined the CSP-induced regulon in S. mutans by microarray analysis. Contrary to pneumococcus, S. mutans responds to increased concentrations of CSP by cell lysis in only a fraction of the population. We have focused on the mechanism of cell lysis and have identified a novel bacteriocin as the M-bM-^@M-^Xdeath effectorM-bM-^@M-^Y. Most importantly, we showed that this bacteriocin causes cell death via a novel mechanism of action: intracellular action against self. We have also identified the cognate bacteriocin immunity protein, which resides in a separate unlinked genetic locus to allow its differential regulation. The role of the lytic response in S. mutans competence is also discussed. Together, these findings reveal a novel autolytic pathway in S. mutans which may be involved in the dissemination of fitness-enhancing genes in the oral biofilm. Streptococcus mutans UA159 were grown with 2 uM CSP or without (uninduced control) to mid-log phase. Total RNA was extracted as described above. The cDNAs were prepared for hybridization using the PFGRC protocol. Microarray chips were scanned using a Gene Pix 4000B (Axon) and analyzed using the TM4 Microarray Software Suite (http://www.tm4.org/). Transcript levels were measured by cDNA hybridized to a fourfold redundant S. mutans microarray and averaged for three replicated hybridizations. Differential gene expression was based on a post-normalization cut-off of M-BM-1> twofold.
