RESUMO
An increasing number of veterinary practices are performing in-office hematology testing. Historically, this involved time-consuming, labor-intensive manual methods. A number of automated and semiautomated hematology instruments are now available for analysis of veterinary samples, which, when used properly, offer more efficient, precise testing than can be achieved through manual methods. This article reviews manual methods for performing a complete blood count and describes some of the available automated hematology instruments. Factors that affect test results and the importance of a quality assurance program are also discussed.

The fungal organism Pseudallescheria boydii was isolated from the cornea of a Quarter Horse with ulcerative keratitis. Despite aggressive hourly medication through a subpalpebral lavage system, with drugs including miconazole and natamycin, the cornea developed a stromal abscess. Orbital exenteration was performed after 3 weeks. The fungal isolate was later determined to be resistant to all 8 antifungal drugs tested. Microscopic examination of the cornea revealed fungal hyphae throughout the corneal stroma and penetrating the Descemet membrane. Pseudallescheria boydii has not been implicated previously as a cause of keratomycosis in horses or in other domestic animals, although cases in human beings have been described.

Calcinosis circumscripta associated with polydioxanone suture material was diagnosed in two young dogs. In each case, the owner noticed a firm mass at the site of a previous surgical incision. Mineralization of soft tissues was visible radiographically. At excision, multiple chalky white nodular masses within the subcutis extended in a linear pattern the length of the sutured incision, but not beyond it. Polydioxanone suture was identified within the center of the nodules, which were identified histologically as calcinosis circumscripta.
