Comparative analyses of clinical and environmental populations of Cryptococcus neoformans in Botswana.
(Mol Ecol, 2015-07)Cryptococcus neoformans var. grubii (Cng) is the most common cause of fungal meningitis, and its prevalence is highest in sub-Saharan Africa. Patients become infected by inhaling airborne spores or desiccated yeast cells ... -
Defining and managing COVID-19-associated pulmonary aspergillosis: the 2020 ECMM/ISHAM consensus criteria for research and clinical guidance.
(The Lancet. Infectious diseases, 2021-06)Severe acute respiratory syndrome coronavirus 2 causes direct damage to the airway epithelium, enabling aspergillus invasion. Reports of COVID-19-associated pulmonary aspergillosis have raised concerns about it worsening ... -
Curvularia alcornii Aortic Pseudoaneurysm Following Aortic Valve Replacement: Case Report and Review of the Literature.
(Open forum infectious diseases, 2021-11)We report the first case of Curvularia alcornii aortic pseudoaneurysm following bioprosthetic aortic valve replacement in an immunocompetent host. Infection was complicated by septic emboli to multiple organs. Despite aggressive ... -
Live Imaging of Host-Parasite Interactions in a Zebrafish Infection Model Reveals Cryptococcal Determinants of Virulence and Central Nervous System Invasion.
(MBio, 2015-09-29)UNLABELLED: The human fungal pathogen Cryptococcus neoformans is capable of infecting a broad range of hosts, from invertebrates like amoebas and nematodes to standard vertebrate models such as mice and rabbits. Here we ... -
Microevolution of Serial Clinical Isolates of Cryptococcus neoformans var. grubii and C. gattii.
(MBio, 2017-03-07)The pathogenic species of Cryptococcus are a major cause of mortality owing to severe infections in immunocompromised as well as immunocompetent individuals. Although antifungal treatment is usually effective, many patients ... -
Microfluidic platform versus conventional real-time polymerase chain reaction for the detection of Mycoplasma pneumoniae in respiratory specimens.
(Diagn Microbiol Infect Dis, 2010-05)Rapid, accurate diagnosis of community-acquired pneumonia (CAP) due to Mycoplasma pneumoniae is compromised by low sensitivity of culture and serology. Polymerase chain reaction (PCR) has emerged as a sensitive method to ... -
Next generation multilocus sequence typing (NGMLST) and the analytical software program MLSTEZ enable efficient, cost-effective, high-throughput, multilocus sequencing typing.
(Fungal Genet Biol, 2015-02)Multilocus sequence typing (MLST) has become the preferred method for genotyping many biological species, and it is especially useful for analyzing haploid eukaryotes. MLST is rigorous, reproducible, and informative, and ... -
Novel Treatment of Cryptococcal Meningitis via Neurapheresis Therapy.
(The Journal of infectious diseases, 2018-08)Cryptococcal meningitis (CM) has emerged as the most common life-threatening fungal meningitis worldwide. Current management involves a sequential, longitudinal regimen of antifungals; despite a significant improvement in ... -
PKC signaling regulates drug resistance of the fungal pathogen Candida albicans via circuitry comprised of Mkc1, calcineurin, and Hsp90.
(PLoS Pathog, 2010-08-26)Fungal pathogens exploit diverse mechanisms to survive exposure to antifungal drugs. This poses concern given the limited number of clinically useful antifungals and the growing population of immunocompromised individuals ... -

The consensus definitions of the Infectious Diseases Group of the European Organization for Research and Treatment of ... -
The Cryptococcus neoformans transcriptome at the site of human meningitis
(mBio, 2014-02-04)Cryptococcus neoformans is the leading cause of fungal meningitis worldwide. Previous studies have characterized the cryptococcal transcriptome under various stress conditions, but a comprehensive profile of the C. neoformans ... -
The Hsp90 co-chaperone Sgt1 governs Candida albicans morphogenesis and drug resistance.
(PLoS One, 2012)The molecular chaperone Hsp90 orchestrates regulatory circuitry governing fungal morphogenesis, biofilm development, drug resistance, and virulence. Hsp90 functions in concert with co-chaperones to regulate stability and ... -
Variation in chromosome copy number influences the virulence of Cryptococcus neoformans and occurs in isolates from AIDS patients.
(BMC Genomics, 2011-10-27)BACKGROUND: The adaptation of pathogenic fungi to the host environment via large-scale genomic changes is a poorly characterized phenomenon. Cryptococcus neoformans is the leading cause of fungal meningoencephalitis in HIV/AIDS ... -
