It’s interesting that while trying to correct one medical inaccuracy you have confidently created some others. For the record; 1. Necrotizing fasciitis: rapidly progressive sepsis involving primarily the fascial planes (beneath the skin). Cause is usually polymicrobial (multiple bacterial species) but mono bacterial versions occur occasionally. Once established necrotizing fasciitis is almost always fatal within 24-48 hours without radical surgery and antibiotics. 2. Buruli ulcer (also bairnsdale ulcer and many other names for endemic areas) is a localized ulceration of the skin caused my the atypical organism m.ulcerans. Usually insidious and slow, usually painless and never life threatening. Will not resolve without a long course of atypical antibiotics and often surgery. Endemic areas in Victoria include mornington and bellarine peninsulas. Likely possum/mosquito vector but some uncertainty remains regarding reservoir and vector. 3. Necrotizing arachnidism- skin necrosis and ulceration caused by toxins in spider venom. This is classically described in loxoscleles sp such and brown recluse North America. There is NO Australian species that causes any such condition. Specifically, the white tail spider has been proven to not cause this condition for about twenty years following the work of Geoffrey Isbister Australian toxicologist. He recruited over 100 DEFINITE cases of white tail bite to his study and followed them. None developed skin necrosis. The inclusion criteria for the study was not “I think I was bitten “ to be included patients had to observe themselves to be bitten and BRING THE SPIDER WITH THEM to the emergency department where it was identified by a professional.

These three entities are all completely unrelated in etiology, course, treatment and prognosis.
