Abstract
This study wasconducted toidentify and characterizethe Candidaspecies isolates from external surfaces of Americancockroachesand houseflies by using Hichrome Candida agar as differential culture medium, germ tube , chlamydospore production and carbohydrate assimilation test. Genotypic confirmation was performed by PCR.The results of this study showed that the predominantCandidaspecies includedC. albicans(44.6%),C. glabrata(23%), C.krusei(19.6%), C. tropicalis(7.4%), C. dubliniensis(3.6%) and C. parapsilisis(1.8%) . All 27 strains indicative of C. albicans and C. dubliniensiswere confirmed by PCR as C.albicans(25 isolates) and C. dubliniensis (2isolates). The study should no difference between the species of Candidastrains from Americancockroaches and houseflies except thatC. parapsilisisand C.dubliniensiswhich were isolated from Americancockroaches. Antifungal susceptibility revealed that nystatin (98%) and fluconazole (89.3%)were highly effective against Candidaspecies,on the hand ,the highest resistance was observed in the case of ketoconazole (16%)and MICs method was excellent for determiningthelevels of dosage pattern foreach species comparewith disc diffusionmethod.
