Abstract:

Chamaecyparis lawsonia, which brings beauty in parks and green space, is attacked by a variety of pathogenic agents specially fungi. In this study, some Chamaecyparis lawsonia available in parks that had disease symptoms were  sampled. After sample collection, in order to isolate fungal pathogens, cuts of the infected plant tissues were placed on PDA (potato dextrose agar) and later were put on WA (water agar) for identifying. Then test of pathogenicity of these isolates on Chamaecyparis lawsonia was done inside the box with plastic stopper. To do this, cuts of colonies of 4 day fungi obtained on PDA medium were put on leaves. The final evaluation was performed after 10 days. This experiment was performed in a completely randomized design with 3 replications and 7 treatments. The results showed that isolated fungi are in 2 groups as following: Alternaria franseriae and Alternaria tenuissima. According to theresults, both species were pathogenic on host. Totally, A. franseriae showed more disease severity compared to A. tenuissima on C. lawsonia.

A Novel Alternaria Species Isolated from Peucedanum japonicum in Korea

We isolated and examined a new Alternaria sp., which causes leaf spots on Peucedanum japonicum in Korea, by using molecular and morphological methods. Phylogenetic analysis based on a combined internal transcribed spacer region analysis and two protein-coding genes (gpd and Alt a1) demonstrated that the causal fungus was most closely related to A. cinerariae and A. sonchi, and relevant to A. br...

In vitro activity of kombucha tea ethyl acetate fraction against Malassezia species isolated from seborrhoeic dermatitis

Background and Purpose: Seborrheic dermatitis is a chronic and recurrent superficial dermatitis in which Malassezia species play an important role. There are different Malassezia species, which have been recently reported to be resistant to common antifungals. Natural sources can be useful alternatives to reduce the emergence of this resistance. Kombucha tea is believed to have potential antimi...

In vitro antifungal activities of Actinomyces species isolated from soil samples against Trichophyton mentagrophytes

Background and Purpose: Cutaneous infections arise from a homogeneous group of keratinophilic fungi, known as dermatophytes. Since these pathogenic dermatophytes are eukaryotes in nature, use of chemical antifungal agents for treatment may affect the host tissue cells. In this study, we aimed to evaluate the antifungal activity of Actinomyces species against Trichophyton mentagrophytes (abbrevi...

Molecular identification and in-vitro antifungal susceptibility testing of Candida species isolated from patients with onychomycosis

Background and Purpose: Candida species are the most opportunistic fungi affecting the nails and resulting in onychomycosis. In this study, we identified and evaluated in-vitro susceptibility of the recovered isolates against fluconazole (FLC), voriconazole (VRC), and clotrimazole (CLT) using the Clinical and Laboratory Standards Institute (CLSI) M27-A3 document. Materials and Method...
