Cyclic Lipodepsipeptides From Pseudomonas spp. - Biological Swiss-Army Knives.

abstract：:The first documented nosocomial outbreak caused by Serratia marcescens in Spain occurred in 1969 at the neonatal intensive care unit (NICU) of the tertiary La Paz Children's Hospital in Madrid, Spain, and based on the available phenotyping techniques at this time, it was considered as a monoclonal outbreak. Only 47 ye...
