Science Friday on New Superbugs

As posted in this blog last week, an article was published in the ASM Journal Antimicrobial Agents and Chemotherapy on May 26 that describes the first discovery in the United States of mcr-1 gene, responsible for colistin resistance, in E. coli in a patient with a urinary tract infection. Colistin is considered an antibiotic of last resort because, …

Urban microbiomes and urban agriculture

About half the human population now lives in urban environments. In 2008, populations of more developed nations were about 74% urban, while about 44% of residents of less developed countries lived in urban areas. It is projected that 70% of the world population will be urban by 2050, with most urban growth occurring in less developed countries. While there …

Research on Plant Microbes May Help with Global Food Security

A recent news article discusses the impact of plant/soil microbiome research on agriculture, specifically helping feed a projected 9 million people in 2050. Novozymes and other corporations are working with researchers and farmers to make microbial products that help promote and optimize plant growth in various ways (for instance, drought tolerance). The idea sounds a bit like …
