Fungemia Model

Fungemia model is a disease in which fungi or yeasts exist in the blood. The most common type is Candida, or systemic candidiasis, which is a disease caused by infection with Candida species. Candidiasis is also the most common blood infection. Infections with other fungi (including Saccharomyces cerevisiae, Aspergillus and Cryptococcus) are also called fungal diseases. Infections are most common in immunosuppressed or immunocompromised patients, patients with severe neutropenia, cancer patients, or patients with intravenous catheters.

Further research found that the most common pathogen in mycemia is Candida albicans, which causes about 70% of fungal diseases, followed by Candida glabrata, Aspergillus, and Saccharomyces cerevisiae. However, recent studies have found that the frequency of infections of Chlorella glabrata, Saccharomyces boulardii, Candida tropicalis, Kluyveromyces and Parapsilosis is increasing. This may be due to the high use of fluconazole or antibiotics.

In the blood, as these fungi multiply, a potentially life-threatening infection will develop, called sepsis. These conditions stem from fungi elsewhere in the body. These symptoms are caused by the intermittent or continuous release of fungus into the bloodstream from other parts of the body, including the lungs, abdomen, and urethra. Therefore, corresponding drugs are needed to treat infections clinically. Creative Diagnostics has established an animal disease model for fungemia research to determine the efficacy of new therapies.


We have established a fungemia model in mice (rat verification is available upon request). We inject a certain dose of fungal infection on the animals by intravenous injection (IV) into the lateral tail vein of the mouse. After confirming that the infection model is established, the test candidate drug can be administered by gavage (PO) or subcutaneous (SC), intravenous (IV) or intraperitoneal (IP) injection. In this process, we can customize each research parameter (animal strain, pathogen, comparator and dosing schedule) to meet the needs of customers.
