The causal agent of this mycotic infection is commonly either ''Trichophyton mentagrophytes'' or ''Microsporum gypseum''. Areas of alopecia and seborrhoea can be found and hair can easily be plucked. Microscopic examination of hair plucked from areas of lesion is sufficient to confirm diagnosis.<br />

This mite infection is commonly caused by ''Trixacarus caviae'', a sarcoptiform mite. Clinical signs usually occur 3-5 weeks after infection and lesions are usually visible around the head, shoulders and back. Hair is easily plucked and skin is usually seborrhoeic and pruritic. In some cases self trauma may also compound problems.<br />
