I S Schwartz, G W Hammond
Candida auris is a fungal pathogen that has recently emerged as a global threat to public health. It was first described in Japan in 2009 and has since been reported in 17 countries on five continents. This case report describes the first reported case of multidrug-resistant C. auris in Canada. In May 2017, a 64-year-old individual was evaluated for chronic otitis externa. Past medical history included a recent hospitalization in India for elective oral surgery that was complicated by an odontogenic brain abscess...

Although many oral ulcers have similar clinical appearances, their etiologies can range from reactive to neoplastic to oral manifestations of dermatological diseases. In patients with an HIV infection, fungal diseases may cause ulceration in the oral cavity; however, there have been few studies of oral ulcerative lesions associated with Candida in patients without an HIV infection. Nevertheless, we encountered chronic oral ulcer associated with Candida among our frequent outpatients without an HIV infection...

SCY-078, the first in a new class of β 1,3-glucan synthesis inhibitors, is being developed as an oral and intravenous antifungal treatment for Candida and Aspergillus species fungal infections. In vitro, studies indicated SCY-078 is an inhibitor of cytochrome P450 (CYP) 2C8 with markedly lower effect over other CYP isozymes. To examine clinically relevant effects of the potential interaction with SCY-078, this phase 1, open-label, 2-period crossover study evaluated the pharmacokinetic parameters of rosiglitazone, a sensitive substrate of CYP2C8 metabolism, in the absence and presence of SCY-078 dosed to therapeutically relevant SCY-078 concentration exposure after repeat dosing...

BACKGROUND: Candida albicans is present as part of the normal gut flora and detected in the oral cavities and GI tracts of around fifty percent of adults. Benign colonization can turn pathogenic causing a variety of mild to severe infections. In a pathogen, the cell wall and cell surface proteins are major antigenic determinants and drug targets as they are the primary structures that contact the host. Cell surface proteins perform a variety of functions necessary for virulence such as adhesion, host degradation, resistance to oxidative stress, and drug resistance...

BACKGROUND: Coexistence of bacteria and yeast in a myriad of microbial communities is indicative of their intimate relationship, which could be the intracellular existence of bacteria inside yeast. In this study, the intracellular existence of bacteria inside yeast and bacterial release from amphotericin B-treated yeasts was examined using polymerase chain reaction (PCR) and microscopy. METHODS: Released bacteria, B1 from Y1 (a gastric yeast) and B2 from Y2 (an oral yeast) were identified as Staphylococcus hominis and Staphylococcus haemolyticus by biochemical tests as well as amplification of Staph-specific tuf and 16S rRNA genes...

Pyogenic granuloma (PG) is a capillary hemangioma mainly found in the skin and oral mucosa, but rarely described in the esophagus. We report the case of a 66-year-old man who consulted for retrosternal pain. Endoscopic studies showed a 28-mm polypoid mass located at the distal esophageal mucosa. The patient underwent endoscopic resection, and the histopathological examination showed a neoplastic proliferation of small blood vessels growing in a lobular architecture, with edematous stroma and prominent inflammatory infiltrate...

In vitro studies suggest that stress may generate random standing variation, and that different cellular and ploidy states may evolve more rapidly under stress. Yet this idea has not been tested with pathogenic fungi growing within their host niche in vivo Here, we analyzed the generation of both genotypic and phenotypic diversity during exposure of Candida albicans to the mouse oral cavity. Ploidy, aneuploidy, loss of heterozygosity (LOH) and recombination were determined using flow cytometry and ddRADseq...

OBJECTIVES: Candida albicans is a commensal pathogen associated with both superficial (mucosal and cutaneous) and systemic infections. The extensive use of antifungal agents has led to reduced susceptibility to the few existing drugs. This situation has encouraged the search for novel antifungal agents. Therefore, in the present study, we investigated the antifungal activity of 2,6-bis[(E)-(4-pyridyl)methylidene]cyclohexanone (PMC). METHODS: We evaluated its in vitro activity against C...

The pleiomorphic yeast Candida albicans is a significant pathogen in immunocompromised individuals. In the oral cavity, C. albicans is an inhabitant of polymicrobial communities, and interspecies interactions promote hyphal formation and biofilm formation. C. albicans colonizes the subgingival area, and the frequency of colonization increases in periodontal disease. In this study, we investigated the interactions between C. albicans and the periodontal pathogen Porphyromonas gingivalis C. albicans and P...

Background : Little is known about the normal range of metal levels in unstimulated saliva, nor whether these might impact Candida carriage in healthy individuals. Both are important in determining which populations are at risk for candidiasis, as the availability of metal ions can influence the growth and pathogenesis of Candida albicans . Objective : We quantified salivary metals of healthy individuals to determine the correlation with C. albicans oral colonization. Design : Unstimulated whole saliva was collected from healthy adults and plated to determine fungal carriage, and metal content was measured using ICP-mass spectrometry (ICP-MS)...
