Catalases of Aspergillus fumigatus [PDF]

Infection and Immunity, 2003
ABSTRACT Upon infection of a host, the pathogenic fungus Aspergillus fumigatus is attacked by the reactive oxygen species produced by phagocytic cells. Detoxification of hydrogen peroxide by catalases was proposed as a way to overcome this host response. A.

Infection of burn wound by Aspergillus fumigatus with gross appearance of fungal colonies

Medical Mycology Case Reports, 2019
The morbidity of invasive aspergillosis in burn patients is low but the diagnosis is difficult and the mortality rate is high. A severe burned patient at the Vietnam National Institute of Burn was suspected of fungal wound infection (FWI) with fungal ...

Regulation of gliotoxin biosynthesis and protection in Aspergillus species.

PLoS Genetics, 2022
Aspergillus fumigatus causes a range of human and animal diseases collectively known as aspergillosis. A. fumigatus possesses and expresses a range of genetic determinants of virulence, which facilitate colonisation and disease progression, including the

Azole resistance survey on clinical Aspergillus fumigatus isolates in Spain.

Clinical Microbiology and Infection, 2020
OBJECTIVES We aimed to assess the percentage of azole resistance in Aspergillus fumigatus in Spain. METHODS Thirty participating Spanish hospitals stored all morphologically identified A.

Acquired immunity to Aspergillus fumigatus [PDF]

Infection and Immunity, 1976
In mice preinfected with Aspergillus fumigatus for greater than or equal to days, administration of cortisone failed to stimulate mycelial growth. The liver and heart of mice preinfected for 14 days resisted infection after a cortisone + conidia challenge.

Structural and biochemical characterization of the exopolysaccharide deacetylase Agd3 required for Aspergillus fumigatus biofilm formation

Nature Communications, 2020
The exopolysaccharide galactosaminogalactan (GAG) is an important virulence factor of the fungal pathogen Aspergillus fumigatus. Deletion of a gene encoding a putative deacetylase, Agd3, leads to defects in GAG deacetylation, biofilm formation, and ...

Germination of Aspergillus fumigatus inside avian respiratory macrophages is associated with cytotoxicity [PDF]

, 2012
Although aspergillosis is one of the most common diseases in captive birds, the pathogenesis of avian aspergillosis is poorly known. We studied the role of avian respiratory macrophages as a first line of defense against avian aspergillosis.

Adaptative survival of Aspergillus fumigatus to echinocandins arises from cell wall remodeling beyond β−1,3-glucan synthesis inhibition

Nature Communications
Antifungal echinocandins inhibit the biosynthesis of β−1,3-glucan, a major and essential polysaccharide component of the fungal cell wall. However, the efficacy of echinocandins against the pathogen Aspergillus fumigatus is limited.
