Background and Aims: Dermatophytosis is one of the most important superficial infections in humans and animals worldwide. Artemisia species, as rich resources of natural products, have a high potential to treat many human diseases. The present study was conducted to investigate the antifungal effects of various extracts from three Artemisia species against dermatophyte fungi. Materials and Met...
Essential oils from oregano (Origanum vulgare L.), mint (Mentha piperita L.), fennel (Foeniculum vulgare Mill.), and pine (Abies alba Mill.) needles and cones, and their active substances thymol, carvacrol, menthol, and anisaldehyde were tested for antifungal activity against Penicillium verrucosum. The lowest minimal inhibitory concentrations (MICs) were achieved for essential oil of oregano, ...
In order to explore the biochemical scope of ochratoxin A-producing penicillia, we screened 48 Penicillium verrucosum isolates for the production of secondary metabolites. Fungal metabolites were analyzed by high-pressure liquid or gas chromatography coupled to diode array detection or mass spectrometry. The following metabolites were identified: ochratoxins A and B, citrinin, verrucolones, ver...
Studies of three monoconidial subcultures of each of 10 isolates of Trichophyton soudanense on seven trichophyton agars revealed variations in growth among the subcultures of each isolate and among the isolates themselves on six agars. In contrast, greater consistency and generally good to excellent growth were noted with all isolates on trichophyton agar 1 (basal medium). These results are con...
In order to determine the extent and causative agents of dermatophytoses in the Hamadan region of west Iran; a study was made during a 9 month period from October 1991 to June 1992. A total of 7495 individuals were studied of whom 681 (9%) were suspected of having cutaneous mycoses. Among them dermatophytoses were the commonest infection (259/681=38%). Of 256 individuals infected with derm...
BACKGROUND The high degree of phenotypic similarity among Trichophyton species makes their identification difficult. OBJECTIVES The current study aims to establish the use of rolling circle amplification (RCA) based on internal transcribed spacer ribosomal DNA (ITS rDNA) as a powerful, simple, and rapid procedure for distinguishing closely related organisms, and specifically to identify Trich...
Dermatophytosis and superficial mycosis are a major global public health problem that affects 20-25% of the world's population. The increase in fungal resistance to the commercially available antifungal agents, in conjunction with the limited spectrum of action of such drugs, emphasises the need to develop new antifungal agents. Natural products are attractive prototypes for antifungal agents d...
Dermatophytosis is considered as one of the most important fungal skin disease affecting both humans and animals otherwise its importance as zoonotic disease. Treatment of ringworm in cattle is expensive and time consuming especially on herd level. Vaccination can be a giant step forward to prevent the occurrence of mycozoonosis between the affected animals with ringworm and susceptible man. Fi...
Tinea refers to superficial infection with one of three fungal genera-Microsporum, Epidermophyton, or Trichophyton-that are collectively known as dermatophytes. These infections are among the most common diseases worldwide and cause chronic morbidity. They are usually diagnosed by direct microscopy and fungal culture, which are burdensome to perform in the clinical setting. To supplement conven...
در این مطالعه ، جهت مقایسه آنتی ژن های پروتئینی واریته های ترایکوفایتون وروکوزوم ( trichophyton verrucosum) ، 5 واریته از این قارچ با منشاء انسانی و حیوانی ، انتخاب شدند . ابتدا این قارچ ها بر روی محیط های اختصاصی کشت داده شده و در دمای 30 و 37 درجه سانتیگراد به مدت یک ماه نگهداری شدند . سپس برای تهیه عصاره پروتئینی ، قارچ های فوق در محیط سایوروی مایع کشت داده شد و از روش برادفورد ( braudford m...
