Identification and susceptibility of Aspergillus section nigri in china: prevalence of species and paradoxical growth in response to echinocandins.
نویسندگان
چکیده
Molecular identification and in vitro antifungal susceptibility tests of 43 Aspergillus section Nigri isolates from China were performed. Aspergillus niger and Aspergillus tubingensis were present in almost equal numbers. All of the isolates had low MIC/MECs (minimum effective concentrations) for the 7 common antifungals, and a paradoxical effect was observed for the first time in response to caspofungin and micafungin.

Aspergillus species are major causes of pre- and post-harvest degradation of agricultural products. During 2004-07, the presence and population of Aspergillus species were studied in various fields and orchards of Fars and Kerman Provinces. Soil samples were collected from 0-40 cm depth. Isolates were recovered from soil using modified Czapek, AFPA and SPDA media. Based on macroscopic and micro...
متن کاملIdentification of fungi of the genus Aspergillus section nigri using polyphasic taxonomy
In spite of the taxonomy of the Aspergillus species of the Nigri Section being regarded as troublesome, a number of methods have been proposed to aid in the classification of this Section. This work aimed to distinguish Aspergillus species of the Nigri Section from foods, grains and caves on the basis in Polyphasic Taxonomy by utilizing morphologic and physiologic characters, and sequencing of ...

The resistance of Aspergillus species to antifungal is increasingly reported and the knowledge of the local epidemiology and antifungal susceptibility pattern is pivotal to define adequate treatment policies. Our study aimed to: 1) describe the in vitro antifungal susceptibility profile of the Aspergillus species isolated from patients with haematological malignancies in Tunisia; 2) compare the...

Recently a species in the genus Talaromyces, a uniseriate species of Aspergillus section Nigri and an isolate each of two widespread species, Penicillium rubens and P. commune, were reported to produce ochratoxin A. This claim was based on insufficient biological and chemical data. We propose a list of criteria that need to be met before an unexpected mycotoxin producer is reported. There have ...

BACKGROUND Aspergillus tubingensis is a black Aspergillus belonging to the Aspergillus section Nigri, which includes species that morphologically resemble Aspergillus niger. Recent developments in species determination have resulted in clinical isolates presumed to be Aspergillus niger being reclassified as Aspergillus tubingensis by sequencing. We present a report of a patient with an osteomye...
