Pulmonary aspergillosis is a life-threatening fungal infection with worldwide distribution. In the present study, clinical epidemiology of pulmonary aspergillosis and antifungal susceptibility of etiologic Aspergillus species were evaluated in one-hundred fifty patients with special focus on the frequency of voriconazole resistance. All the cases were confirmed by the clinical pictures, laboratory findings, and isolation of etiologic Aspergillus species which belonged to two major species, i.

Background: One important complication of the coronavirus disease 2019 (COVID-19) is COVID Associated Mucormycosis (CAM), especially in patients with conditions such as diabetes and in immunosuppressed patients. Systemic acidosis, hyperglycemia, and other biochemical factors such as free iron and β-hydroxybutyrate (BHB) can play a role in this complication.

Materials And Methods: was isolated from a patient at Masih Daneshvari Hospital microbiology laboratory and sub-cultured on the Potato Dextrose Agar (PDA) for 48 hours at 37 °C.

Post-pneumonectomy empyema (PPE), with or without bronchopleural fistula, is a challenging and serious entity with significant mortality and morbidity. PPE is usually caused by bacteria such as staphylococci, streptococci and also gram-negative rods. Among fungal pathogens, species is a very rare cause of this entity.

Acute invasive fungal rhinosinusitis (AIFR) is a life-threatening infection often found in immunocompromised patients. In the COVID-19 era, reports of AIFR have emerged, with high mortality and morbidity rate. This paper presents two cases of COVID-19 associated AIFR with the combined proven fungal etiology of and in case 1 and and in case 2.

Introduction: Acute invasive fungal rhino-sinusitis (AIFR) is a life-threatening infection that is mostly found in immunocompromised patients with serious morbidity and mortality. Recently, reports of AIFR have also emerged among SARS-CoV-2 infected patients.

Case Presentation: A 50-year-old diabetic woman, previously diagnosed with COVID-19 pneumonia, was presented to the hospital with left facial pain on day 12 after discharge.

COVID-19 first emerged in Wuhan, China, in December 2019. Since that time, the frequency of bacterial and fungal coinfections has been continuously increasing. Although invasive pulmonary aspergillosis is being increasingly recognized in association with COVID-19, there is limited information regarding COVID-19-associated mucormycosis.

Background: Allergic bronchopulmonary aspergillosis (ABPA) has been reported in various degrees among patients with persistent allergic asthma (PAA). Currently, there is no gold standard approach for diagnosis of ABPA.

Objectives: In the current study, we aimed the evaluation of three different mainly used algorithms as Rosenberg & Patterson (A), ISHAM Working Group (B) and Greenberger (C) for diagnosis of ABPA in 200 patients with underlying PAA.

Introduction: The aim of this study was to evaluate some virulence factors in Candida albicans isolates from patients with onychomycosis and determine the correlation between these factors and the antifungal resistance profile.

Methods: Seventy species of C. albicans were confirmed using polymerase chain reaction amplification of the HWP1 gene.

Background And Purpose: as a ubiquitous fungus can be found in the respiratory tract of the asthmatic and healthy people. The inhalation of spores leads to an immune response in individuals with asthma and results in the aggravation of the clinical symptoms. The present study aimed to investigate the prevalence of specific immunoglobulin E and G IgE and IgG) against in asthmatic patients.

Article Synopsis
  • Candida parapsilosis sensu stricto is becoming more common in hospital infections, especially in regions like southern Europe, South America, and Asia, prompting a study on its genetic diversity and antifungal resistance in 170 patient strains from Turkey.
  • The researchers used specific genetic techniques to identify the strains and evaluated their resistance to antifungal drugs, finding that posaconazole, caspofungin, and amphotericin B were the most effective treatments.
  • They discovered a high level of genetic diversity among the strains and emphasized the need for strong surveillance and infection-control measures to protect patients from this pathogen.

Background And Purpose: Aspergillosis is one of the most common opportunistic fungal infections in immunocompromised and neutropenic patients. () is the most common causative agent of this infection. Due to variable CO concentrations that pathogens are exposed to during the infection process and to understand the role of CO, we examined the effects of various CO concentrations as one of the environmental factors on morphological changes and induction of antifungal resistance in .

Background: Rapid and accurate identification and evaluation of antifungal susceptibility pattern of isolates are crucial to determine suitable antifungal drugs for the treatment of patients with vulvovaginitis candidiasis.

Materials And Methods: Vaginal samples were collected from 150 women with suspicious vaginal candidiasis, and then cultured on Sabouraoud's Dextrose Agar with chloramphenicol to isolate species. After identification of isolates using polymerase chain reaction-restriction fragment length polymorphism technique, antifungal susceptibility testing of four azolic antifungal drugs was carried out using broth microdilution method according to the CLSI M27-A3.

Background: Anthracosis of the lung occurs due to the deposition of carbon and silica in the mucosa and submucosa, manifested as black lesions. The association of anthracosis with lung cancer has remained to be clearly elucidated The current study aimed to assess the P16, CDH1 and LUNX genes expression level to evaluate the association of anthracotic lesions in the lungs with the occurrence of non-small cell lung cancer. Methods: Forty biopsy samples were taken from the center and 40 from the margins of black anthracotic lesions in the lungs; RNA was extracted from the samples and cDNA was synthesized.

Background: Aflatoxins are highly toxic secondary metabolites mainly produced by . This species can contaminate a wide range of agricultural commodities, including cereals, peanuts, and crops in the field. In recent years, research on medicinal herbs, such as , have led to reduced microbial growth, and these herbs also have a particular effect on the production of aflatoxins as carcinogenic compounds.

The family Trichomeriaceae (Chaetothyriales) mainly comprises epiphytic and epilithic organisms. In some species elaborate ascomata are formed, but for the great majority the species no asexual conidium formation is known other than simple fragmentation of the thallus. The present paper re-establishes the genus Arthrocladium with three non-sporulating species.
