Rapid identification of Candida tropicalis from canine cystitis.
The isolate from urine of a dog with cystitis was molecularly identified Candida tropicalis and its minimum inhibitory concentration (MIC) was determined by a microdilution method. The 25S ribosomal DNA sequence analysis indicated that the clinical isolate was essentially identical to that of C. tropicalis and distinct from other Candida species. The MIC(50) and the MIC(90) of fluconazole (FLZ) for the clinical isolate of C. tropicalis was 6.25 and 25 microg/ml, respectively, indicating that susceptibility of the clinical isolate of C. tropicalis to FLZ was less than for other strains of C. tropicalis as well as C. albicans. The molecular analysis as presented in this study assisted the diagnosis of candidiasis by identifying the yeasts in urine samples within 2 days. The patient dog, a 10-year-old male Shih Tzu dog (7.0 kg) referred for examination of cystitis was successfully treated with itraconazole.
