There are few studies about post-cardiac surgery fungal infections especially by Aspergillus fumigatus. In this paper we report a case of Aspergillus fumigatus endocarditis after tetralogy of Fallot total correction (TFTC), and permanent pacemaker (PPM) implantation. A five-year-old female patient with current history of total correction of tetralogy of fallot was admitted in Rajaie Ca...

OBJECTIVES The objectives of this study were to determine the prevalence of Aspergillus fumigatus and Candida albicans in the sputa of patients with cystic fibrosis (CF), to assess serologic IgE responses of these patients to the presence of fungi in the sputum, to evaluate what effect this may have on clinical status, and to determine how the above-mentioned factors relate to allergic bronchop...

To elucidate the epidemiology of the different forms of avian aspergillosis, 114 Aspergillus fumigatus isolates from sacrificed turkeys and 134 A. fumigatus isolates from air samples were collected and genotyped by microsatellite polymorphism marker analysis. Air sampling confirmed the huge diversity of A. fumigatus populations. Whereas older animals harbored several combinations of genotypes, ...

The case is reported of a patient with cavitary sarcoidosis complicated by an aspergilloma caused by an itraconazole-resistant strain of Aspergillus fumigatus, who was treated with voriconazole. The authors suggest that susceptibility testing of A. fumigatus strains is of value during long-term therapy with itraconazole, and that voriconazole may be a good option for treatment of patients infec...

The specifity of gene encoding the ribotoxin protein in Aspergillus fumigatus was determined by PCR amplification of a portion of the gene. All A. fumigatus strains studied showed the presence of amplifiable ribotoxin product, while none of the other fungal species, with the exception of Aspergillus restrictus, showed this amplification product. Hence, this method may be used for rapid and spec...

Sir, Triazole antifungals are the mainstay of therapy for patients with aspergillosis. Notably, the mortality associated with aspergillosis is high and the rate of treatment failure is much higher if patients are infected with multiple-triazole-resistant (MTR) Aspergillus fumigatus. MTR A. fumigatus strains with the mutation TR34/ L98H occur both in azole-treated as well as in azole-naive patie...

Background and Purpose: Aspergillosis is one of the most common opportunistic fungal infections in immunocompromised and neutropenic patients. Aspergillus fumigatus (A. fumigatus) is the most common causative agent of this infection. Due to variable CO2 concentrations that pathogens are exposed to during the infection process and to understand the role of CO2, we examined the effects of various...

Allergic bronchopulmonary mycosis, characterized by excessive mucus secretion, airflow limitation, bronchiectasis, and peripheral blood eosinophilia, is predominantly caused by a fungal pathogen, Aspergillus fumigatus. Using DNA microarray analysis of NCI-H292 cells, a human bronchial epithelial cell line, stimulated with fungal extracts from A. fumigatus, Alternaria alternata, or Penicillium n...

Aspergillus fumigatus, a ubiquitous airborne fungus, can cause invasive infection in immunocompromised individuals but also triggers allergic bronchopulmonary aspergillosis in a subset of otherwise healthy individuals repeatedly exposed to the organism. This study addresses a critical gap in our understanding of the immunoregulation in response to repeated exposure to A. fumigatus conidia. C57B...

background aspergillus fumigatus (af) is responsible for 90% of human infections. the lung is the predominate site of infection. it is able to colonize in respiratory tract of asymptomatic population and changed clinical features from noninvasive to invasive according to immuncomponent state of individuals. the aim of the present study was to determine the frequency of af immunoglobulin (igg) a...
