The synthesis of a new class of ring peptides that selectively increase the permeability of bacterial cell membranes is reported in Nature (2001;412:452-5). The accompanying in vitro and pilot studies in mice demonstrating the efficacy of these peptides against methicillin resistant Staphylococcus aureus are encouraging. New antimicrobial agents are urgently needed to counter growing drug resistance.

The 1999 outbreak was thought to have affected 2.6% of the population, but the survey data show that 90% of mildly symptomatic and asymptomatic infections were missed.
A clear account of the global distribution of West Nile virus appears in Emerging Infectious Diseases (2001;7(suppl 3)). One of a group of papers in a special supplement, it emphasises “the ease with which exotic pathogens can move between continents,” and the need to improve the surveillance, prevention, and control of vector-borne diseases.
