Project description:ReeS, previously named as CPE1512, was originally annotated as the only hybrid sensor histidine kinase/response regulator in Clostridium perfringens. Further evidence suggests that ReeS is more likely to function as an orphan sensor histidine kinase. A reeS deletion mutant was constructed and the transcriptome analysed using microarrays.

Further evidence suggests that ReeS is more likely to function as an orphan sensor histidine kinase. A reeS deletion mutant was constructed and the transcriptome analysed using microarrays. Total RNA was isolated from the reeS mutant and the wild-type control cells during exponential phase growth. Gene expression levels were compared between the reeS mutant and wild-type strain 13
Project description:RevR is a putative orphan response regulator with a high degree of similarity to YycF from Bacilus subtilis and PhoB from Clostridium kluyveri. A revR deletion mutant of C. perfringens strain 13 was generated and the transcriptome analysed using microarrays.
Project description:The MalNO is a putative two-component signal transduction system, previously known as the VirJI sytem. MalO is the putative cognate response regulator of the MalN sensor histidine kinase. Based on previous evidence that suggested the plc gene, encoding α-toxin, was upregulated during stationary phase in the malO mutant, microarrays were used to analyse the transcriptome of a malO mutant during stationary phase growth.

A revR deletion mutant of C. perfringens strain 13 was generated and the transcriptome analysed using microarrays. Total RNA was isolated from exponentially growing cells from the revR mutant and the wild-type control. Gene expression levels were compared between the revR mutant and wild-type strain 13
Project description:The MalNO is a putative two-component signal transduction system, previously known as the VirJI sytem. MalO is the putative cognate response regulator of the MalN sensor histidine kinase. Based on previous evidence that suggested the plc gene, encoding ?-toxin, was upregulated during stationary phase in the malO mutant, microarrays were used to analyse the transcriptome of a malO mutant during stationary phase growth. Total RNA was isolated from stationary phase cells of the malO mutant and the wild-type control. Gene expression levels were compared between the malO mutant and wild-type strain 13
Project description:Transcriptional profiling of C. perfringens 13 strain compared with strain 13∆cpe1786 erm after growth in minimal medium with 0.5 mM cystine.
Project description:Purpose: Analyze gene expression during C. perfringens colonization in the chicken Transcriptomic profile of mRNA from C. perfrinegns from in vivo and in vitro conditions were determined in biological duplicates by RNA-Seq using Illumina HiSeq 2500
Project description:Transcriptional profiling of C. perfringens 13 strain compared with strain 13?cpe1786 erm after growth in minimal medium with 0.5 mM cystine. two-condition experiment, 13 vs 13?cpe1786 erm, 4 biological replicates for each condition
Project description:Clostridium perfringens is an anaerobic, gram-positive, spore-forming bacterium spread throughout the environment. This bacterium is a common agent in the gastrointestinal tracts of healthy human beings and other mammals. Simultaneously, this agent is one of the most significant producers of toxins among all known bacteria. This expressive toxicity is due to the bacterium’s ability collectively to produce different protein toxins and/or enzymes with diverse modes of action. The present study uses currently developed targeted proteomic methods for the simultaneous detection of selected C. perfringens protein toxins. The method was applied in different kinds of environmental matrices and was used to analyze toxins production in a set of collection strains.
