Schedule

  • Tuesdays at 12 noon - 2pm by Zoom
  • Sept 1, 2020. Week 1. Meet & Greet; Intro to projects
  • Sept 8, 2020. Week 2. Presentations (background, data, and methods), based on assigned readings

Project 1. Structure & evolution of multipartite genome of Lyme disease bacteria

  • Participants: Desiree & Ramon (Summer 2020), Jerry
  • Readings
  • Data set: lp54 & cp26 plasmids
  • TO DO:
    • Week 1. 9/8/2020, 12 noon: 5-slides presentation on multipartite bacterial genome evolution (based on the paper above)
    • Week 2. 9/15, 12 noon: Use prorgram codonO to calculate codon bias (SCUO) for replicons (n=23) on Borrelia burgdorferi B31 genome
    • Week 3. 9/22, 12 noon: codonO paper presentation (Jerry)

Project 2. OspC Cross-reactivity analysis

    • Week 1. 9/8/2020 12 noon: 5-slide presentation on background, material & methods, and data capture using ImageJ
    • Week 2. 9/15: Create Excel sheet to capture immunoblot intensities on C3H mice & P.lucus. Capture background for each serum. Getting ready to makes plots in R/Rstudio

Project 3. Clostridium transcriptome analysis

  • Participants: Eaman, Zaheen
  • Readings
  • Data set: posted on "genometracker.org"
    • Wild type transcriptome at 12 hour, paired-end read files:

    • /home/azureuser/18134XR-29-01_S0_L001_R2_001.fastq.gz
  • To Do
    • Week 1. 9/8/2020 12 noon:
      • A short presentation on C. diff transcriptome (one of the 2 papers above)
      • Demo on read quality using FastQC and mapping reads to reference genomes with bowtie
    • Week 2. Use HT-Seq to quantify RNA abundance for C. diff genes.
