All fungi appeared as brown hyphae on hematoxylin and eosin stain. Zigzag forms of hyphae were common in all species except F. pedrosoi. Neither blastoconidia nor chlamydoconidia were present in tissue infected with D. constricta. D. constricta, W. dermatitidis, and X. bantiana were distributed hematogenously throughout the cerebral hemispheres and demonstrated intraluminal, microvascular invasion whereas, CNS infection due to F. pedrosoi developed by extension from extracerebral dural lesions. F. pedrosoi invaded small to medium‐sized cerebral arteries and veins by extraluminal extension. Microabscesses and early granuloma formation occurred with D. constricta, W. dermatitidis, and X. bantiana, but not with F. pedrosoi, which was associated with only scant cellular inflammatory reaction. Only D. constricta caused a necrotizing ventriculitis with periventricular hemorrhage. Other than yeast‐like cells in W. dermatitidis and F. pedrosoi, ventriculitis in D. constricta, and epidural invasion in F. pedrosoi, these infections are remarkably similar in tissue.","PeriodicalId":18826,"journal":{"name":"Mykosen","volume":"30 5","pages":"215-25"},"PeriodicalIF":0.0,"publicationDate":"1987-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1111/j.1439-0507.1987.tb03970.x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14735012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast to the in vitro indications, all 3 drugs showed fungicidal activity as demonstrated by the exponential decreases in CFU from spleens of infected mice. When relating the fungicidal activity obtained by this technique to the ED50 or ED100 values, KTZ and FTZ appeared to be the most active drugs. Fluconazole compared favorably to KTZ. At twice the ED100 Amph B had no significant effect upon viable yeasts recovered until after day 3 or infection (p ≤ 0.01). Thereafter, the drug was fungicidal.

The isolation of T. terrestre was significantly more often achieved from European shorthairs than from Persian cats, and from the group of European shorthairs and Persians kept together than from an other breeds.
