| isolation of blastomyces dermatitidis from an earthen floor in southwestern ontario, canada. | the first canadian isolation of blastomyces dermatitidis from nature is recorded. this was from the earthern floor of a petroleum filtering shed located in southwestern ontario. a technician working in this environment became infected and was diagnosed as having systemic blastomycosis with meningeal involvement. | 1986 | 3771778 |
| blastomycosis: a new endemic focus in canada. | a survey of the 38 patients resident in ontario from whose sputum, body fluids or tissues blastomyces dermatitidis was cultured by our laboratory between 1970 and 1981 revealed a new endemic focus to the north and east of lake superior, where 20 of 27 traceable patients lived. direct microscopy revealed b. dermatitidis in 90% of the cases. a lack of clinical awareness, however, had often resulted in a delay (average 15 weeks) in diagnosis. in two cases the disease was identified only at autopsy. ... | 1983 | 6616383 |
| epidemiology and clinical spectrum of blastomycosis diagnosed at manitoba hospitals. | blastomyces dermatitidis is a dimorphic fungus endemic to canada and the united states. few reports regarding blastomycosis in canada have been published. we retrospectively reviewed the medical charts of 143 patients with confirmed cases of blastomycosis diagnosed in hospitals in manitoba, canada, from 1988 through 1999. the annual incidence rate of blastomycosis in manitoba was 0.62 cases per 100,000 population, compared with 7.11 cases per 100,000 population in the kenora, ontario district. t ... | 2002 | 11981725 |
| paradise -- not without its plagues: overwhelming blastomycosis pneumonia after visit to lakeside cottages in northeastern ontario. | visiting lakes and cottages is a common leisure activity during summer among most canadians and paradise for some. various leisure activities are involved during these visits, including cleaning and 'airing' the cottage after long-winters, activities at the lakes and dock building etc, exposing the canadians to moist soil and decaying woods -- a source of white or tan mould -- blastomyces dermatitidis that may cause a flu-like illness to severe pneumonia that often remains a diagnostic challenge ... | 2005 | 15871735 |
| blastomycosis in ontario, 1994-2003. | we describe a case of blastomycosis in an 8-year-old boy with blastomyces-associated osteomyelitis and possible pulmonary involvement. we also identify 309 cases of blastomycosis in ontario that were seen during a 10-year period, 57% of which occurred from 2001 to 2003. the overall incidence during the study period was 0.30 cases per 100,000 population. most patients were from north ontario (n = 188), where the incidence was 2.44 cases per 100,000. the incidence in the toronto region was 0.29 pe ... | 2006 | 16494754 |
| blastomycosis in a young african man presenting with a pleural effusion. | blastomyces dermatitidis is a dimorphic fungus endemic to north-western ontario, manitoba and some parts of the united states. the fungus is also endemic to parts of africa. pulmonary and extrapulmonary findings of a 24-year-old african man who presented with weight loss, dry cough and chronic pneumonia not resolving with antibiotic treatment are presented. the unusual occurrence of pulmonary blastomycosis associated with skin lesions and a moderate pleural effusion is reported. | 2006 | 17149463 |
| seasonal variations in the clinical presentation of pulmonary and extrapulmonary blastomycosis. | blastomycosis is a granulomatous infection caused by the thermally dimorphic fungus, blastomyces dermatitidis, for which seasonal variation has been proposed. we conducted a retrospective review of medical records of 324 patients with blastomycosis in manitoba and northwestern ontario. the average age of patients at the time of diagnosis was 39+/-20 (range, 0-85) years. symptoms referable to blastomycosis were first noted in the autumn and winter (september to february) by 63% of the patients. t ... | 2008 | 18651302 |
| clinical characteristics and outcomes in patients with pulmonary blastomycosis. | blastomycosis is an uncommon granulomatous infection caused by the thermally dimorphic fungus blastomyces dermatitidis. the most frequent clinical infections involve the lung, skin, and bone. pulmonary manifestations range from asymptomatic self-limited infection to severe diffuse pneumonia causing respiratory failure. | 2009 | 18931937 |
| red fox as sentinel for blastomyces dermatitidis, ontario, canada. | blastomyces dermatitidis, a fungus that can cause fatal infection in humans and other mammals, is not readily recoverable from soil, its environmental reservoir. because of the red fox's widespread distribution, susceptibility to b. dermatitidis, close association with soil, and well-defined home ranges, this animal has potential utility as a sentinel for this fungus. | 2016 | 27314650 |
