Introduction: COVID-19 is associated with a broad spectrum of bacterial and fungal superinfections.

Case Presentation: We present a case of mucormycosis developing during post-COVID-19 therapeutic management. A 63-year-old diabetic female presented with COVID-19 and received combination therapy per institutional protocol, including dexamethasone, remdesivir, and ivermectin.

  • * Among 647 positive cases, 280 were identified as TMTISG, primarily from tinea corporis and tinea cruris, with 14.3% (40 cases) showing resistance to terbinafine (TRB).
  • * Molecular analysis revealed that most TRB-resistant isolates had mutations in the squalene epoxidase (SQLE) gene, particularly the PheLeu mutation, which appears

Fusarium species are an emerging cause of onychomycosis, and the number of cases has dramatically increased in recent decades worldwide. This review presents an overview of the onychomycosis cases caused by Fusarium species and diagnosis and treatment that have been reported in the literature. The most common causative agent of onychomycosis is F.

Since its first emergence in December 2019, due to its fast distribution throughout the world, SARS-COV-2 become a global concern. With the extremely increased number of hospitalized patients, this situation provided a potential basis for the transmission of nosocomial infections. is a multidrug-resistant pathogen with improved transmission dynamics and resistance traits.

Background And Purpose: Invasive candidiasis is a life-threatening condition that kills a large number of immunocompromised patients each year worldwide. We used post-antifungal effect studies to analyze the activities of anidulafungin (AFG), as a clinically crucial antifungal drug, amphotericin B (AMB), and fluconazole (alone and in combinations) against FLC-susceptible and -resistant () isolates obtained from the cancer patients.

Materials And Methods: We tested the phenomenon of post antifungal effects of FLC, AMB, AFG, and combinations of FLC+AFG, AFG+AMB, and FLC+AMB against 17 isolates obtained from the oral cavity of cancer patients.

Miltefosine, an alkylphosphocholine, has been approved recently for the treatment of visceral leishmaniasis. Miltefosine has shown promise as a treatment for paracoccidioidomycosis, and has mixed activity against other fungi and yeast. There are limited data on the in-vitro activity of miltefosine against azole-resistant and -susceptible Aspergillus spp.

The accurate diagnosis of malaria cases, especially asymptotic and low-parasitemia patients, using robust molecular methods (nested-PCR) have been emphasized. The goal of this study was to detect active cases of malaria in areas with a history of local malaria transmission focusing on the use of molecular tools to ensure that the malaria elimination program has been implemented successfully. In this cross-sectional study, 816 blood samples were taken from immigrants and local residents of malaria-endemic areas in Hormozgan province, Iran.

Otomycosis is a common mycotic infection of the external auditory canal, and Aspergillus species are one of the most frequent causative agents worldwide. The limited antifungal arsenal, the high toxicity and side effects of antifungal agents, and the growing resistance to the currently available antifungals underscore the need for new therapeutic strategies. The present study aimed to evaluate the combined in vitro efficacy of terbinafine and ketoconazole against Aspergillus species with terbinafine high MIC values isolated from patients with otomycosis.

Background: Invasive aspergillosis is one of the most common fungal infections and azole resistance in Aspergillus fumigatus (ARAf) is a growing medical concern in high-risk patients. To our knowledge, there is no comprehensive epidemiological surveillance study on the prevalence and incidence of ARAf isolates available in Iran.

Objectives: The study aimed to report a five-year survey of triazole phenotypes and genotype patterns concerning the resistance in clinical and environmental A.

Article Synopsis
  • The study updates the epidemiology and antifungal susceptibility of tinea capitis (TC) in Iran, analyzing data over one year from six national mycology centers.
  • Out of 2100 clinical samples, 94 cases of TC were identified, predominantly affecting children, with a higher prevalence in males aged 5-9 years.
  • Terbinafine showed the most effectiveness among antifungals tested, while some isolates displayed resistance to fluconazole and griseofulvin, with genetic analysis revealing specific mutations linked to terbinafine resistance.

The treatment of invasive aspergillosis caused by cryptic species remains a challenge due to the lack of randomised clinical trials and investigation of the efficacy and safety of different therapeutic strategies. We aimed to evaluate the in vitro activity of 23 conventional and new antifungal drugs against 54 clinical and environmental Aspergillus oryzae isolates by using the Clinical and Laboratory Standards Institute (CLSI) standard M38-A3. The lowest geometric mean MIC values were found for luliconazole and lanoconazole (0.

Aspergillus flavus and Aspergillus oryzae, two species of Aspergillus section Flavi, are of utmost significance in health, medicine, biotechnology, and foods industries. The methods currently used in mycology for the discrimination of these two closely related species were unable to definitively and rapidly distinguish. The present study aimed to develop a restriction fragment length polymorphism (RFLP) test based on the cyp51A gene to discriminate between A.

Article Synopsis
  • A new pathogenic yeast has gained attention for its rapid spread and resistance to multiple drugs, often causing hospital outbreaks and being misidentified by traditional methods.
  • The report details the first case of fluconazole-resistant otitis in an immunocompetent patient in Iran, showing a high resistance level to the drug yet successfully treated with alternative medications.
  • This case marks the second instance of a fluconazole-resistant yeast strain found in otitis in Iran, differing from the earlier strain identified.
