In vitro and silico activity of piperlongumine against azole-susceptible/resistant Aspergillus fumigatus and terbinafine-susceptible/resistant Trichophyton species.

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.

Clinic-mycological spectrum of infection in diabetic foot ulcers in a tertiary care hospital.

Background And Purpose: In diabetic foot ulcers, if fungal agents, such as species penetrate the cutaneous or depth of the ulcer, it can increase the wound severity and make it more difficult to heal.

Materials And Methods: A cross-sectional study was performed on 100 diabetic patients with a foot ulcer from December 2019 to November 2020 in northern Iran. Patient data and wound grades were recorded in a questionnaire.

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.

Antifungal activity of miltefosine against both azole-susceptible and -resistant Aspergillus strains.

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.

In Vitro Combination of Terbinafine with Ketoconazole Against Aspergillus Species with Terbinafine High MIC Values Isolated From Otomycosis.

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.

In vitro antifungal susceptibility profile of Iranian Fusarium isolates: Emphasising on the potent inhibitory effect of efinaconazole compared to other drugs.

Background: Fusarium species are opportunistic human pathogens that remarkably cause fungal infections ranging from superficial to fatal invasive disseminated infections. Fusarium species are notoriously resistant to the majority of antifungal agents.

Objectives: Therefore, detailed studies regarding in vitro susceptibility are required and may lead to a better prognosis of severe infections.

In Vitro Antifungal Susceptibility Profile of Miltefosine against a Collection of Azole and Echinocandins Resistant Strains.

species are filamentous fungi that cause a variety of infections in humans. Because they are commonly resistant to many antifungal drugs currently available in clinical settings, research into alternative targets in fungal cells and therapeutic approaches is required. The antifungal activity of miltefosine and four comparators, amphotericin B, voriconazole, itraconazole, and caspofungin, were tested in vitro against a collection of susceptible and resistant clinical ( = 68) and environmental ( = 42) isolates.

In vitro activity of 23 antifungal drugs against 54 clinical and environmental Aspergillus oryzae isolates.

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.

High prevalence of asymptomatic nosocomial candiduria due to among hospitalized patients with heart failure: a matter of some concern?

Background And Purpose: Heart failure is a leading cause of hospitalization, and asymptomatic candiduria is common in hospitalized patients with low morbidity. However, in most patients, it is resolved spontaneously on the removal of the catheter. Despite the publication of guidelines, there are still controversies over the diagnosis and management of candiduria.

Phylogenetic Analysis of Clinically Relevant Fusarium Species in Iran.

Fungi of the genus Fusarium are well known as major plant pathogens but also cause a broad spectrum of human infections. Sixty-three clinical isolates, collected during 2014-2017, were identified using a part of the TEF1 gene as barcoding marker. Fusarium fujikuroi species complex (FFSC, n = 41, 65%) showed to be the dominant etiological agent, followed by F.

Molecular epidemiology of Tinea gladiatorum in contact sports in northern Iran.

Background: Tinea gladiatorum as the major health concern among combat athletes and the most common cause of a decrease in the quality of their sports activities.

Objectives: This study aimed to determine the molecular epidemiology of tinea gladiatorum in contact sports in Mazandaran Province, Northern Iran.

Materials/methods: In total, 631 suspected athletes out of 4240 ones were screened for tinea gladiatorum in this cross-sectional study from May 2018 to February 2019.

Catheter-related candidemia and identification of causative species in patients with cardiovascular disorder.

Background And Purpose: Catheter-related blood circulation infection is the most dangerous and serious side-effects of vascular catheters, which leads to the enhancement of the costs, mortality, and hospital stay duration, especially in the Intensive Care Unit. Regarding this, the aim of the current study was to identify the prevalence of catheter-induced candidemia in the Tehran Heart Center, a heart hospital in Tehran, Iran.

Materials And Methods: This study was conducted on patients admitted to Tehran Heart Center for a minimum of 7 days during 18 months.

Low Antifungal Activity of Tavaborole against Yeasts and Molds from Onychomycosis.

The activity of tavaborole, an FDA-approved antifungal drug, was compared to that of four antifungal agents against 170 clinical fungal isolates originating from patients with onychomycosis. Tavaborole had low activity against all isolates compared to itraconazole, terbinafine, and fluconazole, the principal choices for treatment of onychomycosis. Thus, it appears that tavaborole is not a candidate for the treatment of onychomycosis due to species, species, and dermatophytes.

Objective/background: Tuberculosis (TB) continues to be a major public health problem worldwide. This is especially true in Northern Iran, which has high TB prevalence. The chronic nature of this disease is further exacerbated if it is accompanied by fungal infection, which usually remains undiagnosed and thus untreated.

Intravenous Catheter-Associated Candidemia due to Candida membranaefaciens: The First Iranian Case.

The incidence of candidemia due to the uncommon non-albicans Candida species appears to be increasing, and certain species such as Candida (C.) membranaefaciens have been reported in some clinical researches. Vascular catheters are considered the likely culprit for the sudden emergence of hospital-acquired candidemia.

Comparison of diagnostic methods in the evaluation of onychomycosis.

Onychomycosis is a common nail problem, accounting for up to half of all nail diseases. Several nail disorders may mimic the onychomycosis clinically. Therefore, a sensitive, quick, and inexpensive test is essential for screening nail specimens for the administration of the proper drug.
