Candida dubliniensis phenotypically mimics Candida albicans in its microbiological features; thus, its clinical characteristics have yet to be fully elucidated. Here we report the case of a 68-year-old Japanese man who developed C. dubliniensis fungemia during treatment for severe coronavirus disease 2019 (COVID-19). The patient was intubated and received a combination of immunosuppressants, including high-dose methylprednisolone and two doses of tocilizumab, as well as remdesivir, intravenous heparin, and ceftriaxone. A blood culture on admission day 11 revealed Candida species, which was confirmed as C. dubliniensis by mass spectrometry. An additional sequencing analysis of the 26S rDNA and ITS regions confirmed that the organism was 100% identical to the reference strain of C. dubliniensis (ATCC MYA-646). Considering the simultaneous isolation of C. dubliniensis from a sputum sample, the lower respiratory tract could be an entry point for candidemia. Although treatment with micafungin successfully eradicated the C. dubliniensis fungemia, the patient died of COVID-19 progression. In this case, aggressive immunosuppressive therapy could have caused the C. dubliniensis fungemia. Due to insufficient clinical reports on C. dubliniensis infection based on definitive diagnosis, the whole picture of the cryptic organism is still unknown. Further accumulation of clinical and microbiological data of the pathogen is needed to elucidate their clinical significance.

Background: With advancements in healthcare services, there has been an increase in the population of immunosuppressed patients and the frequency of opportunistic pathogens including rare yeasts (RY). We aimed to provide data on the distribution of RY causing invasive infections and their antifungal susceptibility profiles. In this retrospective study, the distribution of RYs obtained between January 2015 and January 2023 examined.

Background: The global burden of bloodstream infection (BSI) due to Candida, and species previously classed as Candida (Candida-like species) is substantial. Recent emergence of Candida auris, fluconazole-resistant Candida parapsilosis and echinocandin-resistant Nakaseomyces glabratus emphasise the importance of global and regional surveillance.
Methods: Blood cultures with growth of Candida/Candida-like species in Queensland, Australia (population ≈ 5 million) over a 20-year period (1 January 2000-31 December 2019) were retrospectively identified.

Candidemia can lead to ocular complications, including endophthalmitis and chorioretinitis. Management of candidemia traditionally included ophthalmic exams. However, due to concerns regarding the utility of performing ophthalmic exams in all patients, there is a need for prognostic factors suggestive of ocular complications.

Invasive candida infections are significant infections that may occur in vulnerable patients with high rates of mortality or morbidity. Drug-resistance rates also appear to be on the rise which further complicate treatment options and outcomes. The aims of this study were to describe the prevalence, molecular epidemiology, and genetic features of bloodstream isolates in a hospital setting.

Illicit drugs, especially those injected intravenously, are becoming increasingly more common worldwide. Individuals who use intravenous drugs often reuse or share needles which predisposes them to life-threatening infections. We present the case of a patient who was injecting intravenous drugs into her internal jugular vein, which eventually led to acutely worsening sepsis secondary to fungal infective endocarditis and bilateral septic pulmonary emboli.
