Mucormycosis (MM) is one of the main invasive fungal infection (IFI), and is determined by filamentous fungi belonging to the order of Mucorales, with a mortality rate ranging from 20 to 60% according to localization. Prompt initiation of adequate antifungal therapy is critical for treating mucormycosis. Early diagnostic is therefore essential. The presence in the Mucorales' cell wall of uncommon monosaccharides open interesting perspectives for the development of specific diagnostic biomarkers.
This study evaluate a diagnostic test for mucormycosis in a cohort of patients with MM and in control groups (high-risk patients without MM and patients with another IFI).

|---|---|---|---|
| Patients with MM | Age : from 3 to 75 years old ; - Specific medical conditions : patient hospitalized in one of the departments of the University Hospital of Lille or Amiens, in whom the diagnosis of mucormycosis will have been made on the criteria below, with compatible clinical and radiological evolution :

| Venous sample | Biological | at Day 0, Day 3, Day 7, Day 14, Day 28 (7 ml blood sample collecting on dry tube) D0 = Diagnostic day |
|
| Measure | Description | Time Frame |
|---|---|---|
| Values of the biomarker studied in the patient group versus control groups, expressed as Optical density (OD). | Detection and quantification of the oligosaccharide biomarker will be performed using a sandwich type enzyme-linked immunosorbent assay (ELISA).Biomarker values could also be reported in arbitrary units / mL (plotting the calibration curve). | at Day 0 |
| Measure | Description | Time Frame |
|---|---|---|
| Kinetics of the biomarker value measured for hospitalized patients, expressed as Optical density (OD). | At each day of interest (at Day 3, Day 7, Day 14 and Day 28), values of OD obtained with an in-house immunoenzymatic sandwich microplate assay for the detection of a specific carbohydrate epitope of Mucorales will be reported for each sera. | at Day 3, Day 7, Day 14 and Day 28 |
