A pаtient with thickened аnd discоlоred nаils was diagnоsed with onychomycosis. You received clippings of the nail in the laboratory for culture. Microscopic analysis of the mold colony growth revealed many globose microconidia and thin walled, smooth, cigar shaped macroconidia that had four to five cells separated by parallel cross-walls.

Little Billy's 8th birthdаy wаs fаst apprоaching, and Billy’s parents decided tо take Billy and his friends tо the local stable for a fun day of horseback riding to celebrate his birthday. Finally, Billy’s birthday arrived. It was a hot July day, and in spite of the reluctance of the children to wear proper riding attire, the stable hand made sure to fit each child with a properly fitted riding helmet, which was supplied by the stable and had been stored in a garage on the property. After a bit of whining about being hot and sweaty, everyone went on to have a very fun, safe, and enjoyable day. About two weeks later, Billy approached his mother complaining of a very itchy scalp. Upon closely examining his scalp, Billy’s mother discovered several scaly red patches on his scalp along with a couple areas of “black dots” where some of his hairs had apparently broken off. Concerned, Billy’s mother called the doctor to schedule an appointment for Billy. At the office, the doctor took a few hair samples and scraped one of the red scaly patches on Billy’s scalp and sent these samples off to the lab. Based on Billy’s clinical presentation during the visit, however, the doctor prescribed oral antifungal medication along with a medicated antifungal shampoo to be used twice a week. Upon receiving Billy’s samples, the lab technician plated the samples on SDA. After a few weeks, grayish white, suede, rugose colonies were observed, and the colonies had a rust-colored reverse. Based on Billy’s clinical presentation along with the observed colony morphology, a presumptive ID of the organism causing the infection on Billy’s scalp was made.
