A 65-year-old man from rural Canada presented with pruritus on his chest; he mentioned that even with frequent bathing the symptoms persisted. Possible arthropod ectoparasites were observed on his chest hair (Figure A) and a specimen was collected and sent to the Microbiology lab for examination. Figure B shows a close-up of one of the organisms observed by the attending microbiologist. The object measured 1.5 mm in length. What is your diagnosis? Based on what criteria?
