A case of primary myiasis in a dog caused by Phaenicia eximia (Robineau-Desvoidy) in Brazil is presented. A young and healthy female dog, Canis familiaris, approximate to 10 d old and still under maternal care, was found to have several eggs and Is: instars larvae in its abdomen and urogenital regions. Samples were collected in Campinas, São Paulo, and transferred to the laboratory for rearing and identification. A comparative analysis of the mitochondrial DNA (mtDNA) with 12 restriction enzymes in 2 sampled populations of P. eximia collected in different hosts (live dog and bovine carcass) and in the same locality revealed that 4, EcoRI, EcoRV, HaeIII, and MspI were suitable for detecting mtDNA markers in the 2 populations.

Corneal degeneration may occur with a deposition of lipids or calcium, or both. Calcareous and lipid degeneration may be either primary or secondary, associated with systemic diseases such as primary hyperlipidemia, hyperlipidemia associated with hyperadrenocorticism, and hypothyroidism. The authors report a case of bilateral corneal lipid and calcium degeneration in a 7-year-old female Poodle with hyperadrenocorticism. The condition worsened with Lysodren(R) therapy but responded to surgical excision.

A 5-year-old Brazilian Fila dog was presented with a history of vision loss, alopecia, and generalized depigmentation of the skin and hair. Clinical examination confirmed generalized depigmentation and pyodermitis. on ophthalmic examination there was depigmentation at the eyelid mucocutaneous junction, associated with anterior uveitis, and bilateral posterior synechia at 360degrees. Both the complete blood count and skin scraping were normal. Skin biopsy showed histiocytary lichenoid interface dermatitis with an absence of pigment within the queratinocytes, and a moderate lymphomononuclear infiltrate and predominance of histiocytes in the papilar derma suggestive of uveodermatologic syndrome. Clinical management consisted of oral and topical administration of prednisone, associated with 1% indometacine eye drops. Methylprednisone was also used twice via the subconjunctival route, at an interval of 15 days. To prevent the development of secondary glaucoma due to posterior synechiae, dorzolamide and timolol eye drops were indicated. Both dermatologic and ophthalmic signs showed good improvement, vision was preserved, and some repigmentation of the skin and hair occurred.
