A fatal case with disseminated Myceliophthora thermophila infection in a lymphoma patient.

We report a lethal Myceliophthora thermophila infection in an immunocompromised patient. Based upon the clinical and mycological presentation, an initial diagnosis of invasive aspergillosis was made, possibly delaying optimal management in the patient. Melanized fungi are emerging pathogens that require early identification to improve their unfavorable prognosis.

Rapid and accurate identification of species belonging to the Candida parapsilosis complex by real-time PCR and melting curve analysis.

Candida parapsilosis is the second most frequent Candida species isolated from blood cultures. Since 2005, C. parapsilosis has been divided into three distinct species based on genetic traits: Candida parapsilosis, Candida metapsilosis and Candida orthopsilosis.

Genotype of 88 Toxoplasma gondii isolates associated with toxoplasmosis in immunocompromised patients and correlation with clinical findings.

We report the genotyping analysis of Toxoplasma gondii isolates in samples collected from 88 immunocompromised patients, along with clinical and epidemiological data. Most of these samples were collected in France during the current decade by the Toxoplasma Biological Resource Center. Lack of specific anti-Toxoplasma treatment, pulmonary toxoplasmosis, and involvement of multiple organs were the 3 main risk factors associated with death for this patient group.

Lung scedosporiosis: a differential diagnosis of aspergillosis.

Lung scedosporiosis is an opportunistic fungus in humans that rarely affects the lung. It may give clinical presentations that are similar to aspergillosis. However, it must be detected because of its frequent resistance to medical treatment.
