Sensitivity, specificity, positive predictive value, negative predictive value and accordance were calculated with blood culture as reference method.

Based on direct detection in blood by alternative methods (e.g. blood culture, alternative PCR), 1-3-beta-D-Glucan, patient risk factors and detection of the same species in other sample materials, each result was categorised as \"proven\", \"probable\", \"possible\", \"improbable\" or \"not assessable\".</p><p><strong>Results: </strong>2105 samples from 1447 unique patients were submitted for analysis during the study period. 94 samples were positive (4.5%) in the T2Candida, with 4 samples positive for more than one target. 26 out of these 94 (27.7%) were also positive in blood culture. 339 (16.1%) samples were invalid.

It is very important to develop novel and effective antifungal agents due to the increasing resistance to commonly used drugs such as fluconazole (FLC). In our previous research, the essential oil of Carica papaya L. seed (PSEO) was extracted and in vitro studies demonstrated that PSEO exhibited strong antifungal activity against C. albicans. It is crucial to investigate the therapeutic effect of PSEO in vivo to develop it into a viable antifungal agent. This study aimed to investigate acute toxicity of PSEO and its in vivo effects on a systemic candidiasis model in mice induced with both FLC-sensitive and -resistant C. albicans. The results showed that PSEO showed no acute toxicity up to 100 mg/kg. PSEO and FLC can improve the water intake, food intake, and mental state of systemic candidiasis model mice. The body weight of the infected mice recovered, the survival rate and splenic index increased, the fungal burden decreased, and pathological damage was alleviated to varying degrees. Moreover, the higher the dose of PSEO, the more pronounced the effect. PSEO exhibited significantly better efficacy than FLC against FLC-resistant C. albicans-induced systemic candidiasis. These findings indicate that PSEO holds great promise as a natural, novel, and effective agent for clinical treatment of C. albicans infections, especially for drug-resistant C. albicans infections.
