PURPOSE: Rare yeasts species are increasingly reported as causative agents of invasive human infection. Proper identification and antifungal therapy are essential to manage these infections. Candida blankii is one of these emerging pathogens and is known for its reduced susceptibility to multiple antifungals. METHODS: To obtain more insight into the characteristics of this species, 26 isolates reported as C. blankii were investigated using genetic and phenotypical approaches...

OBJECTIVE: The frequency and mortality of candidemia remain important. Non-albicans Candida species such as C. auris are increasing. PATIENTS AND METHODS: A retrospective review of adult patients diagnosed with bloodstream infection due to Candida species in the 17 months between July 1, 2020, and December 1, 2021, was performed. Yeast colonies grown in culture were identified by matrix-assisted laser desorption/ionization time-of-flight. Antifungal susceptibility tests of Candida strains were performed with Sensititre YeastOne (TREK Diagnostic Systems Inc...

The first choice of treatment for simple pulmonary aspergilloma is surgery, but in clinical practice, many cases find surgery difficult. We report a case of simple pulmonary aspergilloma in which significant improvement was observed with pharmacological treatment alone, despite initially presenting with a large fungus ball.

Although rare, trans-kingdom infection features an interesting infection biology concept, in which highly versatile pathogenic attributes allow successful infections in evolutionarily highly divergent species. Corynespora cassiicola is a phytopathogenic fungus and occasionally causes human infections. Herein, we report a phaeohyphomycosis case caused by C . cassiicola . Given that sporadic reports may contribute to a lack of awareness of the transmission route, clinical manifestations, and diagnostic and clinical management, we systematically reviewed the cases reported thus far...

BACKGROUND: Recurrent vulvovaginal candidiasis (RVVC) is an important and underestimated fungal infection. OBJECTIVE: We aimed to determine the fungicidal and proliferative capacities of neutrophils and peripheral blood mononuclear cells (PBMCs), respectively and the clinical and microbiological characteristics of a cohort of Colombian patients diagnosed with RVVC. METHODS: A cross-sectional study was conducted. A total of 66 women were included (40 diagnosed with RVVC and 26 healthy women [HW])...

We present two cases with a history of trauma to the cornea and after a few days patients developed symptoms of corneal ulcers with one showing hypopyon as well. Due to strong suspicion of fungal keratitis both cases were treated with topical and intravenously voriconazole. Fungal culture showed white fluffy growth which was identified as Schizophyllum commune by conventional and molecular methods. In both cases surgical intervention was essential. Therapeutic keratoplasty was done in both cases but failed...

Hyalohyphomycosis includes infections caused by various fungal species that produce hyaline, septate, branched hyphae. Fusarium is one such species which usually causes multiple papulo-nodules, ecthyma gangrenosum-like ulcers in immunocompromised individuals. Also, fusariosis is usually difficult to manage and responds favorably to amphotericin B, voriconazole, and posaconazole in disseminated cases. Here, we report an atypical case of cutaneous fusariosis in an immunocompetent individual who presented with multiple large cystic swellings, psoriasiform plaques, and palmoplantar keratoderma, and the patient responded completely to itraconazole...

OBJECTIVE: De-escalation (DES) from echinocandins to azoles is recommended by several medical societies in Candida infections. We summarize the evidence of DES on clinical and microbiological cure and 30-day survival and compare it with continuing the treatment with echinocandins (Non-DES). METHODS: We searched MEDLINE, Embase, Web of Science, Scopus. Studies describing DES in inpatients and reporting any of the outcomes evaluated were included. Pooled estimates of the tree outcomes were calculated with a fixed or random-effects model...

(1) Background: Despite being considered a non-pathogenic yeast, recently, a growing occurrence of Saccharomyces cerevisiae infections has been noted. There is little knowledge about the drug susceptibility of this species. Therefore, the objective of this research was to expand it and determine the drug susceptibility profile of a local collection of clinical isolates of this species. (2) Methods: This study contained 55 clinical isolates identified as Saccharomyces cerevisiae using the MALDI-TOF method. The susceptibility of Saccharomyces cerevisiae was tested to 10 antifungals (amphotericin B, flucytosine, fluconazole, voriconazole, posaconazole, micafungin, anidulafungin, caspofungin, and itraconazole) using MICRONAUT-AT tests and manogepix, a new drug, using the microdilution method according to EUCAST...

Commercial tests are often employed in clinical microbiology laboratories for antifungal susceptibility testing of filamentous fungi. Method-dependent epidemiological cutoff values (ECVs) have been defined in order to detect non-wild-type (NWT) isolates harboring resistance mechanisms. We reviewed the literature in order to find studies where commercial methods were used to evaluate for in vitro susceptibility of filamentous fungi and assess their ability to detect NWT isolates according to the available ECVs...

This study assessed the changes in Candida species distribution and antifungal susceptibility patterns during the coronavirus disease 2019 (COVID-19) pandemic compared with a pre-pandemic period in Korea. We retrospectively investigated the specimen, species type, and antifungal susceptibility of Candida isolates obtained between 2016 and 2022. Data between two periods were compared: 2016-2019 (pre-pandemic) and 2020-2022 (pandemic). We included 11,396 clinical isolates of Candida species (5137 isolates in the pre-pandemic and 6259 isolates in the pandemic)...

AIMS: The aims of this study are to investigate the etiology, microbiological spectrum, and risk factors associated with visual outcomes of fungal endophthalmitis (FE) in a tertiary eye specialty hospital in Shanghai, China. METHODS: This was a retrospective, single-center case series. The clinical characteristics, etiology, microbiological spectrum, and management, as well as the visual outcomes, were analyzed. Logistic regression was used to analyze the factors related to visual outcomes...

UNLABELLED: The emergence of azole-resistant Aspergillus fumigatus (AR Af ) across the world is an important public health concern. We sought to determine if propiconazole, a demethylase inhibitor (DMI) fungicide, exerted a selective pressure for AR Af in a tomato production environment following multiple exposures to the fungicide. A tomato field trial was established in 2019 and propiconazole was applied weekly until harvest. Soil, leaf, and fruit (when present) samples were collected at baseline and after each propiconazole application...

Muyocopron laterale is a type of endophytic fungus that parasitizes monocotyledonous plants. Cases of humans and other mammals being infected by M. laterale are very rare around the world. We report the first case of subcutaneous mycosis caused by M. laterale in China. A kidney transplant recipient was admitted for Pneumocystis carinii pneumonia and subsequently developed left calf redness and swelling due to a M. laterale infection. The patient was treated with sulfamethoxazole and voriconazole and underwent five surgical debridements and vacuum sealing drainage (VSD) applications with the left leg...

INTRODUCTION: Aspergillus species are ubiquitously found in the environment worldwide and are important causative agents for infection. Drug resistance among Aspergillus species is emerging, hence the present study was undertaken to look for antifungal susceptibility profiles of clinical and environmental isolates of Aspergillus species. MATERIALS AND METHODS: During the period from January 2018 to June 2019, a total of 102 Aspergillus isolates (40 clinical, 40 hospital, and 22 community environment) were tested for antifungal susceptibility testing for determination of minimum inhibitory concentration (MIC)/minimum effective concentration (MEC) as per Clinical and Laboratory Standards Institute (CLSI) M38-A3 method for itraconazole, voriconazole, amphotericin B, and caspofungin...

PURPOSE: To report a case of endogenous Lomentospora prolificans endophthalmitis treated with the novel antifungal agent Olorofim. CASE REPORT: A 57-year-old man developed disseminated Lomentospora prolificans with right endophthalmitis on the background of immunosuppression following lung transplantation for interstitial lung disease. He was treated with early vitrectomy, intravitreal voriconazole, and systemic Olorofim, voriconazole and terbinafine. His symptoms improved and remained stable in the right eye...

Scedosporium apiospermum species complex are widely distributed fungi that can be found in a variety of polluted environments, including soil, sewage, and decaying vegetation. Those opportunistic pathogens with strong potential of invasion commonly affect immunosuppressed populations However, few cases of scedosporiosis are reported in immunocompetent individuals, who might be misdiagnosed, leading to a high mortality rate. Here, we reported an immunocompetent case of systemtic infection involved in lung, brain and spine, caused by S...

Imidazoles are a category of azole antifungals that encompass compounds such as ketoconazole, miconazole, esomeprazole, and clotrimazole. In contrast, the triazoles group, which includes fluconazole, voriconazole, and itraconazole, also plays a significant role. The rise of antibiotic resistance in fungal pathogens has evolved into a substantial global public health concern. In this study, two newly synthesized imidazo[1,2-a]pyridine derivative (Probe I and Probe II) molecules were investigated for its antimicrobial potency against of a panel of bacterial (Gram-positive and Gram-negative bacteria) and fungal pathogens...
