[ 3 ] - مروری بر کراتیت قارچی تشخیص، درمان با تاکید بر اپیدمیولوژی بیماری در ایران
Keratomycosis is the most important cause of ocular morbidity which is mainly occurred in field worker as an occupational disease. Fungal keratitis is caused by yeast and filamentous fungi. Aspergillus and Fusarium species are the most prevalent filamentous cause of keratomycosis. The most common yeast cause is Candida species especially C. albicans. In the last reports, trauma to the cornea...
[ 4 ] - مروری بر عفونت قارچی در بیماران سوختگی، تشخیص و درمان
Burn wound is a suitable environment for growth and reproduction of microorganisms. The tissue in the burn wounds is not live and do not have blood vessels so, polymorphonuclear antibodies and systemic antibiotics cannot diffuse into it. Thus, the condition of the wound is provided for the growth of bacteria and opportunistic fungi such as Candida, Mucor, Rhizopus, Penicillium, and Aspergillus....
[ 5 ] - تعیین توالی در چند ناحیه ژنی (MLST): یک روش تایپینگ مولکولی با قدرت تمایز بسیار بالا جهت شناسایی گونه‌های کاندیدا آلبیکنس در مطالعات اپیدمیولوژیکی
Candida spp. are ubiquitous yeasts commonly. Those are commensally and opportunist pathogens in humans. Candidiasis in immunocompromised patients and patients with severe underlying diseases or critical illnesses need aggressive diagnosis or treatment procedures. Candida albicans (C. albicans) is the most frequently isolated species. For prevention of nosocomial infections caused by C. albicans...

[ 9 ] - مروری بر مایستوما در ایران، با تاکید بر شمال کشور
Mycetomas are chronic granulomatous fungal diseases that involve cutaneous and subcutaneous tissues. Mycetomas are caused by fungi (Ëumycetoma) or fungus-like bacteria (Âctinomycetoma). The exogenous causative agents are geophilic organisms which introduced by traumas. We review 90 cases of mycetoma in Ïran from 1972 to 2009. There are rare reports of Mycetomas from Ïran with most cases (6...

Background and purpose: Onychomycosis is a nail fungal infection caused by various species of dermatophytes, yeasts and non-dermatophytic molds and represents about 30% of cutaneous mycotic infections. The goal of this study was to investigate the frequency of onychomycosis and its associated factors in patients referred to Boali Sina Hospital and Toba dermatology outpatient clinics, Sari. ...
[ 11 ] - تعیین گونه مالاسزیاهای جدا شده از بیماران مبتلا به پیتیر یازیس ورسیکالر و درماتیت سبوروئیک، با روش PCR-RFLP
Background and Purpose: Lipophilic yeast of the genus Malassezia are members of normal human cutaneous micro flora which are also associated with several skin diseases. It is strongly suspected that Malassezia species are responsible for pityriasis versicolor (PV), and seborrhoeic dermatitis (SD). Considering various sensitivities among Malassezia species to antifungal, accurate species identif...
[ 12 ] - Fungal peritonitis and cancer near the abdominal regions
Objective: Guidelines have recommended that structured programs to support fungal peritonitis in cancer patients should be introduced. The role of fungi in causing peritonitis is rare, but fungal peritonitis has high morbidity and mortality. The abdominal fullness may be secondary to the fungi accumulation of peritoneal fluid. The isolation of fungi, particularly Candida from peritoneal fluid s...
[ 13 ] - In vitro antitumor activity of patulin on cervical and colorectal cancer cell lines
Background and Purpose: Patulin is a mycotoxin produced by some molds,especially Aspergillus and Penicilium, and is responsible for mycotoxicosis in animals and humans.There is still not very detailed data about the anti-cancer potency of patulin, but some reports demonstrated that it induces cellular apoptosis and toxicity. Materials and Methods: To determine the efficacy of patulin as a ther...
[ 14 ] - Clinical features, diagnosis, and outcomes of rhino-orbito-cerebral mucormycosis: A retrospective analysis
Background and Purpose: Rhino-orbito-cerebral mucormycosis (ROCM) is a rare disease with acute and fulminant manifestation. This infection is associated with high morbidity and mortality rates.

[ 15 ] - In vitro activity of five antifungal agents against Candida albicans isolates, Sari, Iran
Background and Purpose: Candida albicans is the most common causative agent of candidiasis. Candidiasis management is dependent on the immune status of the host, severity of disease, and the choice of antifungal drug. Antifungals, specifically triazoles, are widely administered for the treatment of invasive fungal infections. Herein, we aimed to evaluate the in vitro susceptibility of C. alb...
