This rabbit has developed dandruff and is losing hair. On physical examination, reddened, hairless, scaly patches are noted over the head and back. On a faecal flotation, the organism shown was recovered.
| Question | Answer | Article | |
| What is this organism? | Cheyletiella parasitivorax. This organism is referred to as ‘walking dandruff’ and its presence in the fecal examination is simply fortuitous as a result of grooming.
Identify the mite by the large palpal claws on its anterior surface. It can often be seen grossly visible moving in the heavily scaled areas. Use clear cellophane tape to collect the mites from the fur and skin. Examine the tape microscopically. |

| How would you treat the condition? | Administer ivermectin for two to four doses or treat the rabbit by dusting with carbaryl or permethrin powder at weekly intervals. Alternatively, use lime/sulfur dips every two weeks for two to three treatments.
