Background And Objectives: The ability of to produce biofilm is considered an important pathogenic factor. In addition, the low sensitivity of biofilms to antifungal drugs is a challenge for patients, clinicians, and laboratory workers. We aimed to investigate the effectiveness of luliconazole and caspofungin on the planktonic and biofilm types of strains.

Molecular epidemiology, diversity, and antifungal susceptibility profiles of clinical and environmental mucorales: a five-year multicenter study in Iran (2018-2023).

Purpose: The incidence of Mucormycosis has increased during the last decades globally due to more patients being at risk for these life-threatening infections. Early diagnosis and proper selection of appropriate antifungal therapy are vital in enhancing patient outcomes. Mucorales species present a significant challenge due to their resistance to many drugs, so investigations for new therapies and strategies must be undertaken.

Development and Evaluation of SYBR Green Real-Time PCR for Rapid and Specific Identification of Trichophyton indotineae.

Background: Since 2017, dermatophytosis caused by the newly introduced species Trichophyton indotineae has gained new interest worldwide due to the rise in terbinafine resistance and difficulty in the treatment of recalcitrant infections. Distinguishing T. indotineae from other Trichophyton species based on morphological features is impossible and DNA sequencing is necessary for accurate identification.

Aspergillus hubkae, a Novel Species Isolated from a Patient with Probable Invasive Pulmonary Aspergillosis.

A 50-year-old man, previously diagnosed with pulmonary tuberculosis and lung cavities, presented with symptoms including fever, shortness of breath, and cough. A pulmonary CT scan revealed multiple cavities, consolidation and tree-in-bud in the upper lungs. Further investigation through direct examination of bronchoalveolar lavage fluid showed septate hyphae with dichotomous acute branching.

Potential Inhibitory Effect of Miltefosine against Terbinafine-Resistant .

Several prolonged and significant outbreaks of dermatophytosis caused by , a new emerging terbinafine-resistant species, have been ongoing in India in recent years, and have since spread to various countries outside Asia. Miltefosine, an alkylphosphocholine, is the most recently approved drug for the treatment of both visceral and cutaneous leishmaniasis. Miltefosine in vitro activity against terbinafine-resistant and susceptible / species complex, including , is limited.

Time and cost-efficient identification of Trichophyton indotineae.

Background: During the past 5 years, an outbreak of recalcitrant dermatophytosis due to a novel Trichophyton species generally resistant to terbinafine, T. indotineae, has spread out from South Asia to many countries around the World. These isolates cannot be reliably differentiated from other Trichophyton spp.

Quantitative analysis of in vitro biofilm formation by clinical isolates of dermatophyte and antibiofilm activity of common antifungal drugs.

Background: The ability of dermatophytes to develop biofilm, as one of the virulence factors in fungal infections which contribute to antifungal resistance, is an outstanding aspect of dermatophytosis that has been noted recently. Because of the paucity of data about the biofilm formation by dermatophytes and their susceptibility to antifungal drugs, this study evaluated the biofilm formation by clinical isolates of dermatophytes and antibiofilm activity of common antifungals widely used to manage dermatophytosis.

Methods: The ribosomal DNA internal transcribed spacer (ITS) regions sequencing for species identification of 50 clinical dermatophyte isolates was performed.

A simple multiplex polymerase chain reaction assay for rapid identification of the common pathogenic dermatophytes: Trichophyton interdigitale, Trichophyton rubrum, and Epidermophyton floccosum.

Background And Purpose: The most common etiological agents of human dermatophytosis in various parts of the world are , , and . The main aim of this study was to design and evaluate a simple and straightforward multiplex polymerase chain reaction (PCR) assay for reliable identification/differentiation of these species in clinical isolates.

Materials And Methods: The reliable sequences of several molecular targets of dermatophytes species were used to design a multiplex PCR for the identification of common pathogenic dermatophytes.

In vitro activities of 8 antifungal agents against geophilic dermatophyte isolates.

Background: Members of the Nannizzia gypsea complex are globally the most common geophilic dermatophytes which cause infection in animals and human. Although the susceptibility patterns of anthropophilic or zoophilic dermatophyte species to antifungal agents are well documented, the effectiveness of such drugs against geophilic species have rarely been explored.

Objectives: This study was aimed to evaluate the in vitro antifungal activity of common and new antifungals against a set of environmental and clinical geophilic dermatophyte isolates.

Pediatric candiduria, epidemiology, genotype distribution and virulence factors of Candida albicans.

The presence of Candida species in urine may be due to colonization of this species in the bladder, urinary catheter, and perineum. Candida albicans has been the most commonly isolated from urine samples in patients with candiduria. Several virulence factors include adhesion to host cells, secreted extracellular enzymes, phenotype switching, and biofilm formation are contributing to the pathogenicity of C.

Discovery of New Members, T. persicum and T. spiraliforme spp. nov., as a Cause of Highly Inflammatory Tinea Cases in Iran and Czechia.

Pathogens from the Trichophyton benhamiae complex are one of the most important causes of animal mycoses with significant zoonotic potential. In light of the recently revised taxonomy of this complex, we retrospectively identified 38 isolates that could not be resolved into any of the existing species. These strains were isolated from Iranian and Czech patients during molecular epidemiological surveys on dermatophytosis and were predominantly associated with highly inflammatory tinea corporis cases, suggesting possible zoonotic etiology.

Diversity of Geophilic Dermatophytes Species in the Soils of Iran; The Significant Preponderance of .

A molecular epidemiology study was conducted between 2016 and 2017 by a network of collaborators from 12 provinces in the Islamic Republic of Iran. A total of 1484 soil samples from different habitats were screened for the presence of dermatophytes by using the hair baiting technique. The primary identification of isolates was carried out by amplification and I restriction fragment length polymorphism (RFLP) of the internal transcribed spacers regions of ribosomal DNA (ITS-rDNA).
