Beach Sand Mycobiome is currently among the most important health challenges for viticulture in the world. Remarkably, the study of fungal communities in coastal beach sand and recreational waters remains underexplored despite their potential implications for human health. This research aimed to assess the prevalence of fungal species and the antifungal susceptibility profiles of fungi recovered from the beaches of the Persian Gulf and the Sea of Oman.

To treat and heal the rough and thick nail tissue affected by fungal agents, a high dose and plasma concentration of this drug is necessary. This, however, poses a life-threatening risk due to the cytotoxic side effects, drug-drug interactions, and adverse physical and chemical properties associated with oral medications.

Although most agents are susceptible to current antifungal drugs available in clinical settings, frequent relapses and failures, especially in cases due to Trichophyton indotineae, have been frequently reported. Therefore, alternative targets and therapeutic approaches are highly required.

In recent years, the widespread emergence of drug resistance in yeasts and filamentous fungi to existing antifungal armamentariums has become a severe threat to global health. There is also concern regarding increased rates of azole resistance in Aspergillus fumigatus and Terbinafine resistance in Trichophyton species. To overcome this concern of resistance to regular therapies, new antifungal drugs with novel and effective mechanisms are crucially needed.

Background: Although the Candida species continue to be the most frequent colonizer of neonatal skin, a clear increase of colonization due to rare yeast-like fungi has been reported. In this study, we report an unusual high prevalence of Cryptococcus diffluens colonization in neonates admitted to the neonatal intensive care unit (NICU) over a 1-month period.
Methods: From January 2020 to June 2021, the study included all neonates who were admitted to the NICU of Bu Ali Sina Hospital at least 28 days old.
Background: Coronavirus disease 2019 (COVID-19) is a pandemic outbreak of RNA coronaviruses (SARS-CoV-2), associated with acute respiratory distress syndrome, multiple organ failure, and death. The surface electrocardiogram is the first line assessment of cardiac electrical system. We aimed to interpret classically the electrocardiographic parameters at admission and during hospital course and association of them with prognosis in patients admitted with diagnosis of infection with SARS-CoV-2.

The objective of the present study was to isolate and characterize dermatophytes from dogs and cats in Iran.
Method: From December 2022 to May 2023, skin and hair samples were collected from symptomatic and asymptomatic cats and dogs in Mazandaran, a northern province of Iran.

Background: The current study aimed to identify Iranian Nakaseomyces (Candida) glabrata complex species in the clinical isolates and determine their antifungal susceptibility profile.
Methods: In total, 320 N. glabrata clinical isolates were collected from patients hospitalized in different geographical regions of Iran.
A 2.5-year-old stray dog showed signs of hair loss, mild skin crusting, and redness on extremities and trunk. The etiologic agent was confirmed as Trichophyton indotineae by sequencing of ITS region.

Methods: Here we report a pediatric case of Aspergillus quadrilineatus cerebral infection in a recently diagnosed COVID-19-positive patient underlying acute lymphocytic leukemia. Morphological, molecular methods, and sequencing were used to identify this emerging species.
Background And Purpose: Given the high mortality rate of invasive candidiasis in hospitalized pediatric patients, it is crucial to establish a predictive system to achieve early diagnosis and treatment of patients who are likely to benefit from early antifungal treatment. This study aimed to assess the colonization index, species distribution, and antifungal susceptibility pattern of strains isolated from pediatric patients with high colonization index (CI).
Materials And Methods: This study was carried out at the Children's Medical Center in Tehran-Iran.
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.

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.

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.

Samples from a total of 67 stations, distributed amongst 32 cities along the Caspian Sea coastline, were collected during the summer of 2021 on sunny days. The samples were collected from each station, including both dry/wet sand and shoreline water. The grown samples were primarily analyzed for the macro/microscopic morphologic features of the fungi.
