Female adult beardie, clinically well and bright except in the previous 2 weeks had had this black spreading across it&#39;s back, pics below: Ddx included CANV / bacterial.

I hadn&#39;t thought about UV exposure as a potential cause, that&#39;s a good point! Thanks very much for that, I will assess the situation with that and perhaps ask them to change the bulb regardless. Thanks again!</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/88221?ContentTypeID=1Sun, 12 May 2013 20:20:59 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:054e5d0e-1cb9-4c36-9600-3685d8960f57Marie Kubiak<p>Hi,</p> <p>usually in CANV/bacterial infections there are clear pathogens identifiable on histopath. Is the pathologist familiar with reptile skin as it can be very difficult to assess pathology if compared to mammalian skin.</p> <p>If no pathogen identified on histopath or culture then consider a non-infectious aetiology - I have seen similar changes recently in a montane chameleon that had been exposed to an excessively high intensity of ultraviolet light due to a faulty bulb. The histopath was non-specific inflammatory changes and gross appearance was similar to your case. Also the distribution on your beardie would fit with the regions of most intense exposure to a basking heat/UV light.</p> <p>Marie</p><div style="clear:both;"></div>
