It had been housed indoors, with 2 other ferrets, 2 cats, and humans that lacked signs or symptoms of disease.<\/jats:p>\n<jats:p><jats:bold>Clinical Findings<\/jats:bold>\u2014Physical examination revealed a thin body condition, tachypnea, an increase in respiratory effort, and retching. Splenomegaly was detected during abdominal palpation. Clinicopathologic analysis revealed lymphopenia, lactic acidosis, hypoglycemia, hypocalcemia, hypoalbuminemia, and hyperglobulinemia. A pulmonary bronchointerstitial pattern was evident on radiographs, and abdominal ultrasonography revealed a suspected pancreatic mass and mesenteric lymphadenopathy.<\/jats:p>\n<jats:p><jats:bold>Treatment and Outcome<\/jats:bold>\u2014After 2 weeks of medical treatment and once clinical signs resolved, an exploratory laparotomy was performed and a lymph node biopsy specimen was collected. Histologic evaluation of the specimen revealed <jats:italic>Cryptococcus<\/jats:italic>-like organisms. Antifungal treatment was initiated with itraconazole (PO) and amphotericin B (IV). The ferret died after 2 days of treatment. A full necropsy was performed, revealing multicentric cryptococcosis affecting the lungs, brain, spleen, and multiple lymph nodes. Paraffin-embedded, formalin-fixed lung tissue was submitted for DNA extraction, and the organism was identified as <jats:italic>Cryptococcus neoformans<\/jats:italic> var <jats:italic>grubii<\/jats:italic>.<\/jats:p>\n<jats:p><jats:bold>Clinical Relevance<\/jats:bold>\u2014To the authors' knowledge, this is the first report of disseminated cryptococcosis in a North American ferret. This case is unique in that the ferret lived indoors, in a geographic region in which reports of cryptococcosis are rare. The genotyping technique used to identify the <jats:italic>Cryptococcus<\/jats:italic> strain can aid in better understanding the epidemiology of cryptococcosis.<\/jats:p>","DOI":"10.2460\/javma.236.7.770","type":"journal-article","created":{"date-parts":[[2010,4,1]],"date-time":"2010-04-01T07:13:24Z","timestamp":1270106004000},"page":"770-774","source":"Crossref","is-referenced-by-count":27,"title":["Disseminated,
