This study seeks to investigate the frequency of Aspergillus species among Iranian patients and their susceptibility to seven antifungals. In a cross-sectional study, 233 Aspergillus isolates were collected from 11 university hospitals in Iran between 2018 and 2021.

Black cumin seeds (Nigella sativa) have shown an inhibitory effect against Candida albicans. In this work, the inhibitory effect of standardized extract and different fractions of Nigella sativa seeds has been evaluated on both nystatin-susceptible and resistant strain of C.

The food of infants should be safe and free of various pollutants, including breast milk mycotoxins. This study aimed to measure the mycotoxin of Aflatoxin M1 (AFM1) in human milk samples obtained from lactating mothers living in Rafsanjan city, Iran.

Due to the dispersion of the light amount of essence through the AWs, they have their specific pleasant smell, taste, and medicinal properties. In Iranian traditional medicine, AW is used to treat gastrointestinal disorders.

The present study aimed to investigate the effects of addiction to opium and fungal infection on plasma levels of certain cytokines including interleukin-4 (IL-4), IL-6, IL-17, Interferon gamma (IFN-γ) and transforming growth factor-β (TGF-β).
Methods: Present study included 72 individuals who were divided into 4 groups: 1) opium-addicted with fungal infection; 2) opium-addicted without fungal infection; 3) non-opium-addicted with fungal infection; and 4) normal individuals (non-opium-addicted and non-fungal infection).
Background: Cell-mediated immunity (CMI) by CD4 + Th (T helper)-type cells is the predominant host defense mechanism against Oral Candidiasis (OC) in HIV-infected individuals. Weakened CMI and depletion of CD4 + T cells are the main factor contributing to the output of OC in HIV-positive individuals. The cytokines produced by Th1, Th2 and Th17 cells play a role in mediating an increased susceptibility to OC during HIV infection.

Background: Aflatoxins (AFs) are secondary hazardous fungal metabolites that are produced by strains of some Aspergillus species on food and feedstuffs. Aflatoxin B1 (AFB1) is one of the most important AF with high toxicity. Prevention of AF production and their elimination from food products is a matter of importance for many researchers in the last decades.

Aspergillus infection causes a spectrum of diverse diseases particularly in lung according to host immunity. The two major entities are invasive pulmonary aspergillosis and chronic pulmonary aspergillosis.

In the last decades, the number of people suffering from dermatophytoses has seriously increased, which may be due to the development of resistant strains to a range of antifungal drugs. The present study was aimed to evaluate the antidermatophytic properties of eight extracts from the selected spices and herbs, which were ethno-medicinally used in Iran against Trichophyton mentagrophytes, Trichophyton interdigitale, Microsporum canis, and Microsporum gypseum (10 strain of each). The in vitro antifungal activities of the extracts from four spices and four plants were evaluated by the broth macro dilution method against four dermatophyte strains.

These fungi are the most common infectious agents in humans that are free of any population and geographic area. Microsporum canis is a cause of dermatophytosis (Tinea) in recent years in Iran and atypical strain has been isolated in Iran.

Moreover, antileishmanial and cytotoxicity activity of B. vulgaris and berberine against promastigotes of Leishmania major and Leishmania tropica were evaluated by colorimetric MTT assay.
