I am proud to share a new paper out of our lab. We showed that our antimicrobial works with copper and zinc to kill MRSA & Staph epi. It can function through mature biofilms they form and on multiple surfaces. This outstanding work was led by Yamil Sanchez-Rosario.

N-benzyl-N-methyldithiocarbamate (BMDC) combines with metals to produce antimicrobial and anti-biofilm activity against methicillin-resistant Staphylococcus aureus (MRSA) and Staphylococcus epidermidis | mSphere
Antimicrobial-resistant bacteria, such as Staphylococcus aureus (MRSA) and Staphylococcus epidermidis, are a significant cause of morbidity and mortality in vulnerable populations, contributing to an escalating health and economic burden. Biofilms are an important reservoir that protects bacteria from immune clearance and antimicrobial agents. However, current strategies to effectively target MRSA biofilms are limited. This research describes a therapeutic approach that can disrupt biofilms in both MRSA and S. epidermidis, thereby enhancing bacterial clearance.

This Players Era Championship seeding for the championship and 3rd and 4th place games is...well...dumb. Run up the score and risk your players getting hurt to play for the most money, but beat the best teams in the land...meh.
