RESUMO
BACKGROUND: Postgrooming furunculosis, as previously described in the dog, is a type of pyoderma that typically responds to routine antimicrobial therapy. Systemic clinical signs are common but are usually mild. ANIMAL: A 3-year-old spayed female great dane was presented with marked dorsal furunculosis of 24 h duration. The clinical signs and blood analyses were consistent with sepsis, systemic inflammatory response syndrome and disseminated intravascular coagulopathy (DIC). METHODS AND RESULTS: Skin culture revealed multi-drug resistant Pseudomonas aeruginosa infection. The dog did not respond to aggressive medical therapy including intravenous antibiotic therapy, fresh frozen plasma and haemodynamic support, and was humanely euthanized. Postmortem findings were consistent with postgrooming furunculosis with associated sepsis and DIC affecting multiple organs including the lungs and brain. CONCLUSIONS AND CLINICAL IMPORTANCE: Postgrooming furunculosis can progress to sepsis and multiple organ dysfunction in the dog and can lead to death.

Fungal disease is a rare cause of pericardial effusion in dogs. This report describes the first case of fungal pericardial effusion and myocarditis secondary to the fungal organism Inonotus tropicalis. A 9-year-old female spayed French bulldog with a multi-year history of treatment with glucocorticoids for management of atopy was presented for exercise intolerance, ascites and weight loss. Physical examination and thoracic imaging revealed enlarged peripheral and cranial mediastinal lymph nodes, left ventricular thickening and cardiac tamponade secondary to pericardial effusion. Fine needle aspiration of the cranial mediastinal lymph node showed pyogranulomatous inflammation with short, thin and poorly septated hyphae. Culture of the aspirate yielded a fungal isolate identified as Inonotus tropicalis based on morphologic features and rRNA gene sequencing. Postmortem examination showed myocardial thickening with multifocal to coalescing, firm, white, ill-defined nodules. Histology confirmed the presence of disseminated fungal infection with extensive myocardial involvement. Inonotus tropicalis is an opportunistic poroid wood-decaying basidiomycete. Infection in this dog was likely the result of chronic immunosuppressive therapy.
