Remnants of Antibiotics Persist in Treated Farm Waste, Research Finds

advanced-anaerobic-digestion.jpg

Each year, farmers in the U.S. purchase tens of millions of pounds of antibiotics approved for use in livestock. When the animals’ manure is reused as fertilizer or bedding, traces of the medicines leach into the environment. New research holds troublesome insights with regard to the scope of this problem.

How Did Gonorrhea Become a Drug-Resistant Superbug?

UNC School of Medicine researchers have identified mutations to the bacterium Neisseria gonnorrhoeae that enable resistance to ceftriaxone that could lead to the global spread of ceftriaxone-resistant “superbug” strains.

Mathematical Modeling Offers New Way to Understand Variable Responses to Targeted Therapy

Cancer therapies that target a specific protein have improved outcomes for patients. However, many patients eventually develop resistance to these targeted therapies and their cancer comes back. It is believed that differences among tumor cells, or heterogeneity, may contribute to this drug resistance. Moffitt Cancer Center researchers are using a unique approach by combining typical cell culture studies with mathematical modeling to determine how heterogeneity within a tumor and the surrounding tumor environment affect responses to targeted drug therapies.

A Chink in Bacteria’s Armor

• Scientists untangle the structure of a recently discovered bacterial wall-building protein, found in nearly all bacteria • The discovery unveils potential weak spots in the protein’s molecular make-up • Findings can pave the way to next-generation broad-spectrum drugs that disrupt the protein’s function and disarm harmful bacteria

Could a Paper Device Diagnose Infectious Disease?

Imagine a small paper device that can rapidly reveal from a drop of blood whether an infection is bacterial or viral. The device could help reduce the overuse of antibiotics – which kill bacteria, not viruses. Misuse of antibiotics has led to antimicrobial resistance, a growing global public health issue.
