“…C. dubliniensis has been frequently associated to oral and systemic candidiasis in HIV-positive patients 4,19,23 under chemotherapy and bone marrow transplant patients 3,18 , sometimes liable for death cases 28 . Thus, it is very important to identify among the population of immunossuppressed patients those who have C. dubliniensis in their oral microbiota, and how big is this ratio (cfu/mL).…”

Candida spp. can lead to infections or even fungal sepsis particularly among immunocompromized individuals.ObjectiveThe aim of the present study was to analyze the presence of Candida spp. among patients subjected to orthotopic heart transplantation.Material and MethodsOral rinses from 50 patients subjected to orthotopic heart transplantation, aged 13 to 70 years, 40 males and 10 females, were examined. Sexage-oral conditions matched-control included 50 individuals who were not subjected to any kind of transplantation and were not immunocompromized for any other reason. Counts of yeasts were expressed as median values of logarithm of cfu/mL and were statistically compared by Mann-Whitney’s test. The heart transplant and control groups were compared for the presence of Candida spp. by chi-square test (p<0.05).ResultsThe results showed statistically significant difference (p=0.001) in the prevalence of Candida spp. between the transplantation and control groups. Counts of yeasts (cfu/mL) in the transplanted group were significantly higher than in the control group (p=0.005). Candida albicans was the most prevalent species isolated from both groups.ConclusionIt was concluded that Candida yeast counts were higher in the heart transplant recipients than in the controls. There was higher variation of Candida species among the heart transplant patients and the most frequently isolated samples were: Candida albicans, Candida glabrata and Candida tropicalis. Isolates of Candida dubliniensis was not found in either of the groups.

“…dubliniensis has been more frequently detected in individuals with systemic metabolic alterations, in addition to HIV-positive and diabetic patients (13,14). However, several studies have reported the detection of C. dubliniensis from not only the oral cavity but also other body sites in both HIV-positive and HIV-negative patients(15-17).…”

Distribution of Candida dubliniensis from Denture Membrane Surfaces

et al. 2013

It is difficult to separate Candida dubliniensis from Candida albicans in clinical specimens, because the phenotypic characteristics of C.dubliniensis are similar to those of C.albicans.In this study, we examined the distribution of C. dubliniensis from denture membrane surfaces and the genotype of C. albicans. Twenty-two subjects provided samples obtained using swabs from the denture membrane surfaces of worn dentures. CHROMagar TM Candida medium was used for the isolation of Candida spp. Candida spp. were detected in 18 of the 22 subjects, and Candida spp. constituted 0.256% (range: 0~1.41%) of the total cultivable microorganisms. C. dubliniensis was detected in 5 of 18 subjects (27.8%). C. dubliniensis was found in coexistence with C. albicans or C. glabrata. As a result of the classification of C. albicans by genotype analysis, the predominant genotype was found to be A. In conclusion, we found that C. dubliniensis was present in healthy denture-wearing individuals.

Dedico este trabalho:Aos meus amados pais, José Sabino e Vera Lúcia, por tudo, emespecial, pelo amor, confiança, apoio animals taken part in the study, the dogs over 4 years old and those which presented periodontal diseases had a higher isolation percentage. Yeasts were identified 43 of the 45 isolates, being that 86%(37) were from the genus Candida spp, 11,6% (5) belonged to the genus Trichosporon spp., and 2,3% (1) belonged to the genus Malasseziapachydermatis.The susceptibility profile through the "Etest®" method identified a relevant resistance of some strains to the antifungal drugs commonly used in the veterinary medical clinic. This found highlights the relevance of the continuity of this study to improve the clinical conduct and to explain many relapse treatments in both animals and humans.
