Abstract:
Aims:The present study determined Candida species occurrence in the mouth of HIV/AIDS, pregnant women and healthy individuals, and Candida susceptibility to antimycotics.
Methodology and results:A cross-sectional study of the Candida species occurrence and their in vitro sensitivity to nystatin, clotrimazole, ketoconazole and fluconazole was studied. Oral swabs were taken from the dorsum of the tongue of 63 HIV/AIDS patients, 38 pregnant women and 53 apparently healthy humans served as control. All participants gave their consent. The samples were cultured for isolation of Candida species. The susceptibility of commonly used antimycotics against Candida species was determined using agar-well and disc-diffusion methods. The broth dilution method was adopted in the determination of the minimum inhibitory concentration of the drugs. The rate of Candida species colonization in HIV/AIDS patients was higher than that among pregnant women and apparently healthy humans. Candida albicans had the highest frequency. Candida species displayed higher sensitivity to nystatin and clotrimazole than ketoconazole and fluconazole. Candida albicans exhibiting low sensitivity to fluconazole were found in the mouth of AIDS patients, pregnant women and apparently healthy humans.
Conclusion, significance and impact of study:Candida species prevalence was highest among HIV patients. Candida albicans had the highest frequency among the study groups and had reduced susceptibility to fluconazole. The findings of the study underscore the need for regular surveillance and susceptibility testing of Candida isolates before prescription of antimycotics, especially in cases of chronic infection, as well as the development of safe and efficacious treatment alternatives since Candida isolates are becoming less susceptible to fluconazole. - Full text:20.2022my0028.pdf
