We invite you to attend a special topics research seminar to learn about Merck's efforts to discover new drugs aimed at fighting deadly, antibiotic-resistant bacterial infections, better known as "superbugs." The featured presenter is Scott S. Walker, PhD, Principal Scientist at Merck Research Laboratories. Antibiotic resistant Gram-negative bacteria are a serious and growing threat to human health. To combat this crisis, novel agents that circumvent established resistance mechanisms are urgently needed. Merck's use of large-scale antibacterial phenotypic screening and systematic hit triage has revealed novel targets and novel inhibitors of established targets. Turning these leads into drugs remains a significant challenge. No registration is required. This event is sponsored by Research Development, the Center for Medical Innovation, and Corporate and Foundation Relations.
