Contributed by Cory Schlesener, B.S. Historically it has been difficult to categorize prokaryotes into taxonomic units. Advances made have utilized DNA sequence identity to profile organisms at a higher resolution.  Older technologies based on genomic DNA hybridization, or sequence comparison … Continue reading →

Contributed by DJ Darwin Bandoy, PhD Candidate I am now in my year four of my PhD studies in Integrative Pathobiology in UC Davis, still in the middle of the COVID-19 Pandemic. I presented in the lab meeting yesterday the … Continue reading →

Contributed by Cory Schlesener, B.S. DNA sequencing, in a high throughput process, generates errors in the reads, such as low confidence nucleotide based calling. Quality control is needed to evaluate the quality of the sequencing output and identify undesired features. … Continue reading →

Contributed by Carol Huang, Sr. Research Specialist                      @BartWeimersLab The equilibrium of gut microbiota is fundamental to our health. The gut microbiota composition established at birth which changes with aging, diet, … Continue reading →

Contributed by DJ Darwin Bandoy, PhD Candidate One distinguishing feature of this pandemic is the rapid release of whole genome sequencing data. These sequences are usually uploaded in public databases with minimal accompanying metadata. While dates and geographic origin are … Continue reading →

Contributed by Cory Schlesener, B.S. One important component of a genome’s overall composition is the larger structure of how conserved blocks of genetic sequence are arranged. As segments of DNA recombine, sequences are introduced into new locations and/or orientations in a … Continue reading →

Contributed by Ashleigh Flores, M.S. Within the GI Tract, horses can host up to 1015 bacterial cells, with the highest population residing within the caecum. Recent studies have revealed that distinct individual ecosystems for each compartment of the equine gut … Continue reading →

Contributed by DJ Darwin Bandoy, Ph.D. Candidate California is in full lockdown again after a surge in cases. This is a consequence of opening too early when the cases are not fully suppressed. This requires people to wear masks, practice … Continue reading →

Contributed by Ashleigh Flores, M.S. Corynebacterium pseudotuberculosis biovar equi is responsible for the highly contagious disease in horses commonly known as “Pigeon Fever”. Although flies act as the primary vector, soil serves as a reservoir for this robust microorganism. Research … Continue reading →
