Pseudomonas folliculitis

Notes from a talk given at the European Congress of Clinical Microbiology & Infectious Diseases, 2011.

The skin infections it can cause are probably under-recognised, but where public health surveillance is in place, have appeared in small case clusters. Some states have active monitoring of spa bath hygiene measures.
